January 1986, space engineer Hambini speaks to he masses, he emphasizes his masterfully work on the Challenger Spaceship, a few hours before the launch 😂
Jesus, that is literally the worst mechanicing (if that's a word) I have ever seen!!! I have always been a bit suspicious of Hambini but this train wreck means I cannot ever take him seriously again!! I would honestly sack any mechanic working for me for practices like this! Thanks for highlighting this.
Another Hambini roast. Standard engineering practise is to grease any metal/ composite interface/threads. He may be an aerodynamicist or whatever as well as a plumber but not a mechanic I would trust.
Just stumbled on this video, Reginald. Never seen the Hambini video before. I’d just like to say that the jury isn’t out! 😂 This is a genuine “how not to”.
Wow, this video has just blown my mind! I had never seen that Hambini vid, but yikes 😳 I swear about 50% of steerer bearings out there are under-preloaded (loose), and about 40% are over-preloaded, leaving a sliver of bearings out there actually operating as they should be. That was painful watching Hambini cranking his up so tightly, and crazy to think that that same person actually designs and sells bearing systems (bottom brackets). Not only that, but he has taken on the mission of producing remedial bottom brackets to fix everyone else's flawed designs. That was an eye-opener!
@@reginaldscot165 This was the third Hambini-bashing video of yours that I watched. One comment said that this headset vid of his might be from 7 years ago, so it's feasible that he's learnt a lot in those 7 years, but it's still surprising to see an engineer treating bearings and an assembly in this way. His unsympathetic use of hand tools is also concerning, but then I see a lot of engineers operating tools in this way! My experience is that it's rare for modern engineers to be good at the theoretical AND practical aspects of engineering, which seriously needs addressing. I can't blame you for meeting fire with fire after he tried to call you out. I hope you manage to continue keeping these vids more technically critical than personal and retalliatory 🙂
Also, why did the compression plug have to come out, especially if your going to bash on the steerer? Leaving the compression plug installed at least means you're hitting metal and not raw unsuppored carbon. Also how he just keeps bashing it risking the compression ring to gouge into the steerer 🤦 Just a little tap to get some play and then push the steerer back up to release the compression ring from the bearing and the ring just slides off and the steerer drops. Also just clamp the seat post and tilt the bike down and that way nothing can fall anyways. I've never seen an "expert" litteraly get every step of the most basic maintenance task wrong 🤦
Serious question, Can you explain why you hold your Titanium bike in high acclaim when it has a defective bottom bracket? According to the SRAM specifications, your frame hole is too small. Do you feel that you ignore manufacturer data because you know better?
Not really a serious question is it old boy. 😉 It’s a PF30, in it is a PF30 BB with a 30mm spindle. It spins fine. 👍🏻 Stop trusting people who are dishonest. 😘
@@reginaldscot165So, SRAM is dishonest? I mean the BB specs are on Sram website and on your video it shows your BB be undersized. So who is dishonest, you, Sram or hambini for pointing that out?
The backwards brake pad is telling. As an engineer, I'm an electrical engineer, your job is ALL ABOUT DETAILS. Small details. Large details. All of them. The more critical the detail, the more attention you pay. If you're a good engineer, this mindset is ingrained into everything you do. If you're not a good engineer, well, you might mount brakes backwards.
We are all doing our best to service our bikes at home, it’s good to see others sometimes struggling as well w certain challenges and parts and have a debate on these technical issues 👍
Specific greases and weights are needed for each application. E.g ti prep for titanium etc. Where 2 different metals contact each other there is galvanic corrosion. Water and salt is the catalyst therfore cleaning and re-greasing is needed more in wet or dirty conditions. This maybe stating the obvious but it is often neglected.
I totally agree. He recently started that he had never herd of corrosion with aluminium and stainless steel… can you believe that coming from an aerospace engineer?
That top cap is obviously threaded to the bolt. Also, do you know any doctors who smoke or drink excessively? He may treat his own bikes carelessly but that has no bearing on his competence.
@@reginaldscot165Also I live in Norway rid eon salty roads no issues with top cap, I out a bit of grease at the bottom threads and underneath the bolt head. Never gets stuck. To me it looks like months of corrosion by sweat from his head. I ride a MTB so would not be in that position often, but simply cleaning the bike after each ride would help. It's so quick and easy to do. Only times I don't do it is if my back is really bad. He talks about proof about grease attacking the resin but where is it? Where's the proof of the threaded cap? 😁
sorry to brake your logic but your brake on pushing on the bolt straight.. you are wrong. if you have a rubber, tightened at the "entrance" of the friction force, as you brake harder, the tension on the brake pad will elongate it thin it out (reducing the thickness of the pad), and also start tearing it. the bolt of the brake pad is not meant to hold the braking force, but just the rubber insert not to fall out. if you have it as shown in Hambinies video, you will have compression in the direction of braking force, making the pad thicker and also it will be butting up against the insert holder. also you will have more pat material where your biggest braking force is generated... from most of the comments it seams that you are trying to find a way to make it look worse than maybe it is. 1st of, you assume the video is uncut and every part of the video, blt not being tight is as is... the wheel was supported by the tool drawer from underneeth... which you would see maybe... but to your credit you have a lot of good points and explanation
Sorry I found this comment impossible to understand. I’m guessing your first language is not English? If you can get a friend who speaks better English to help with making this comment clearer I will happily try to read it again. 👍🏻 Or maybe try Google translate, that seems to work well for me. All the best! 👍🏻
I as a rule dont like people point scoring off each other, I would never criticise another persons video. However I was pretty shocked at the poor practice in this video. Its certainly not the way I work. I also cringed at the top cap being tightened, that was pretty much the worst thing on the video. This is after all a pretty simple job for a decent bike mechanic 👍
But is it a simple job for a aerospace engineer? 😂 Well normally I wouldn’t “point score” but he made the mistake of lying about me and my tools in his video so now the gloves are off! 😉
7:51 After sending a clarification I did not get any answer from ITM, so I tried to send more info trying to explain what I'm asking, I referenced this video, and shared a link to it, a screen shot. But still no answer. It's simple, thing to answer, is the stem cap threaded? only two options Yes, No. Strange they can't answer a simple question.
I’d bet money it’s not, I found some photos online of the cap and it looks like every other design out there. The only thread one I’ve seen is the FSA one designed for cannondale about 6 years ago. It looks very different.
@@reginaldscot165Update: I sent them a new request, still no answer. Maybe they are ignoring me this time. I don't know. Maybe they are busy who knows. It would be best for them to give a clear answer or even response to Hambini's video if Hambini is wrong. But yes I saw the pictures of it it looks like any compression plug top cap. Or post more pictures.
There's one subtle issue glossed over in this video that is worth mentioning - the clamp bolts on the stem should be tightened and loosened incrementally, alternating between the 2 bolts, in order to ensure the loading on the clamp is reasonably even from top to bottom at all times. A quick thought experiment to explain why - If both bolts are initially evenly tightened and one is loosened completely, then the remaining tension (Which is more than the tension either bolt was carrying while both were tight) is carried entirely by the remaining bolt, leaving the bolt and more importantly the clamp loaded significantly more than they were when both bolts were tight. Similarly, when tightening the bolts, if you tighten one bolt up to the recommended torque and then tighten the second one, also to the recommended torque, the first bolt will now be loose. This is not mentioned even in the official instructions for installing a lot of parts with paired bolts on the same clamp, so you can follow the official installation procedure to the letter, using a torque wrench and still have a dangerously installed stem with a loose stem bolt afterwards. A scenario where this is even more important is on Hollowtech II crank pinch bolts, where the bolts are even closer together and in the much stiffer clamp at the end of the crank. It takes a little longer to tighten and loosen paired bolts like this (Especially on cranks where you usually have to spin the cranks 180 degrees for access each time you switch bolt), but at least you can be sure they are sharing the load evenly and the part is firstly clamping firmly enough to stay in place and secondly that the stress on the part is carried evenly across the clamp as per the part's design. Speaking as both a very well qualified mechanical engineer and someone who worked on and off for over a decade as a bike mechanic, that Hambini video is absolutely shocking from both sides of the fence. One trick I have seen, and even occasionally used, with GT85/WD40 is when MTBing in extremely muddy conditions is that spraying the downtube and chainstays with WD40 just before going out riding in thick mud does stop mud sticking to the frame, for a while at least.
Excellent comment and a very interesting point about the bolt tightening process. I must admit that I do know that you should follow that protocol, but sometimes I don’t… for the cranks I almost always do, it’s become second nature by this point. Thank you for the detailed explanation. Always good to hear from an expert. 🙏🏻🙂
Shimano manual for their 105/Ultegra/DA groupsets does say the tightening of those crank arm pinch bolts must be done incrementally. I always initially use just an allen key for the first coupe turns until the second bolt stops getting loose when I turn the other one, then switch to a torque spanner and do them up alternately to 3/6/9 and finally 12Nm. For stem face plates where there are mostly 4 bolts the tightening is done incrementally in a diagonal pattern too.
@@Bonky-wonkyonly I back my statements up with evidence and I actually prove Hambini to have lied on several occasions. You might like hambini but “facts don’t care about your feelings.”
I laughed so hard when i saw that big hammer in his hand 😂 And the sound of those hits...hahahahaha 🤣 Hammerini making a foul of himself again. I bet anybody will do that job better after watching a youtube video with how it should be done properly.
When I was doing q group project as part of my degree, I had one guy complain about the module leader. I believe his exact words were "What does he expect me to do? I'm not an engineer!". This is a final year student, mind! Anyway, that's when it dawned on me that he was only there to please his parents. Absolutely zero passion for the craft. I wouldn't be surprised it this idiot turns out to have been the same. "Engineer" in name only.
This video needs some kind of content warning. Watching that bike getting that treatment has left me traumatized. And what's going on with that bar tape?
OMG what did I just watch? This is even worst then a novice diy!! The brake pads In reverse, no proper tools , the corrosion! Not removing the wheels , the bar tapes , clamping on the top frames , not putting grease etc etc . This is aerospace standard!
CFRP is made of uh... carbon, and epoxy. That's it. Nothing overly complicated, nor all that chemically sensitive. You can manufacture your parts on the cheap, in which case they will kind of suck, or you can spend the big money and do it properly, in which case you'll get something reasonably skookum (though still ill-suited for making bike frames out of; or deep ocean subs). Either way, chemically they're about identical. In both cases I don't see how regular ol' water resistant grease will do anything nasty.
For the life of me, I don't understand why he didn't remove the front wheel, before removing the fork... I'm not skillful in anything,and I can be a bit of...cluts😅 but I would definitely remove the wheel first, before removing the fork,to be serviced,greaced, cleaned, whatever... Why he didn't loosen the screws,when removing the stem... Again...idk😅 And that squeaking sound when installing the stem on the steerer, I mean...why making it harder than it has to be..And no lubricant of whatsoever????? Man.. And... just because someone is highly educated engineer, doesn't mean he's good with tools,or just plain old bike service! We learn..!😅😊 Greetings from Croatia from Kris 😎
@@waiakalulu7544 I kinda like the dude! He can be very informative,and even funny 🤣 But watching that service video,idk... I thought engineers know better,or something 😅
I know a lot of engineers. They know the Theory with no practical application. It’s a rare element where both meet. I worked in the mechanical hands on realm for years then got my degree.
It’s not just road salt, Hambini lives close to the sea, in the well known aerospace capital of the UK, Grimsby😀 That regular ride to ‘the oil refinery’ exposes the bike to wind blown salty sand from the Humber estuary. A few weeks commuting in those conditions and any bike will experience corrosion. Grease would indeed help, GT85, a more expensive version of WD40 aka kerosine with added teflon doesn’t.
I don't think so. I lived on the coast for several years and routinely rode parallel with the coast with the wind blowing from the water. I've never had anything nearly as bad as that.
It's not quite the same as WD40. GT85 contains PTFE which acts as a lubricant. In fact it's often advertised as a 'bike lubricant' although I doubt they intend it for bearings which are more appropriate with grease. For a general frame protector (steel) I use furniture polish, in other words wax. It's not long lasting so it does need to be done on a regular basis.
@@vihuelamig I guess you shouldn't be spraying anything like WD40 or GT85 all over bearings as it'll dissolve the grease and you'll be left with whatever light lubrication it provides (i.e. not enough for bearings long term). If GT85 is sold as a bike lubricant I guess they would mean for the chain, cassette and so on.
Totally agree. What’s crazy is some of his fans try to pretend everything here is totally fine. Just like the meme of the dog in the burning house: “this is fine.” 😆
I am a complete amateur bike mechanic but have successfully looked after my 4 bikes for years now. I would never count myself as an expert but this clown does ?? When he preloaded his top cap i nearly screamed out. U need to just take the play out the system then maybe an extra quarter of a turn for luck. Technically u can remove the top cap once the stem bolts have been tightened up but I wouldn't. I would never have done that even at the beginning of my maintenance journey. And the wooden mallet. Wtaf 😅. I've heard mapdec raving about hambini and this is the man himself ? No thank you won't be listening to his opinion about anything
I have never had to bang out my fork. Maybe a soft tap from my hand, but never had to bang on it like like that. I have a friend who owns a bike shop. She has a "wall of shame". His headset would go onto that wall. And who works on the fork and doesn't remove the wheel?
Good question, maybe he isn’t very good at mechanical things? I also used to watch his channel, until he decided to completely lie about me and my tools. 🤷🏻♂️
The video of Hambini is alright, the only error is in the title of his video, which should read "How to butcher a new headset bearing so that it can rust in peace"
Hes not even using a Torque wrench on a carbon head tube waw! 31.38 the top cap the back is higher than the front like he's stripping threads not putting it back in straight!.be why it's screaming!
Yes, this is a really strange thing what Hambini is doing here. Especially when you know how much precision and meticulousness he puts into his bottom brackets (of which i got a PF30, that works very well). Besides - i am a very thorough „greaser“ myself. I grease literally almost ANY screw on my bikes. Most important: The pedal axis screws! I had a case some time ago with a so-called bike „designer“ who sold me a bike where he had installed the pedals without any grease. It was almost impossible to loosen them later on. Never forget to put LOTS of grease on those threads…
Grease is almost always a good idea, certainly in bike terms. I think the precision of his BBs is over complemented, especially when you consider it’s the very expensive CNC machines at his workplace that he uses for free to make his BBs. When you have industrial grade programmable equipment you didn’t pay for it’s very easy to make precise products. I know this from personal experience: I used to work with industrial welding robots. Now personally I’m terrible at hand welding, I can do it, but I’m just awful. However, when I plug a few numbers into a welding program for a robot that robots makes some beautiful welds that out class the work of a professional hand welder with 20 years experience! Hambini is the same, we see in this video that he is just awful with his hands, not even capable of the most basic maintenance tasks. But, he puts some numbers into a programmable industrial machine and then all of a sudden everyone is complementing him on his work. 😂
Reginald, may I ask for advice? I got a Triban RC120 for free, it's brand new and I liked it. Planning to do some upgrade to 105 groupset, what are your thoughts? What would you do? I also will upgrade tires and little things like carbon seatpost and stem...
That’s awesome! Contact points! Contact points! Contact points! 😂 Tyres first, spend as much as you can afford on hood tyres. My personal favourite is the conti 4 seasons. Then saddle is the next most important. Find one that works for you, try before you buy. The rest I mostly unimportant to be honest. Just have fun at that stage. Tape would be next cheapest, wheels the best bang for your performance buck. 🙂👍🏻
From viewing this video of his, he looks like an amateur bike mechanic. But many of your criticism of him in your video show that you are often wrong as well (from his response video), and yet you claim to be a trained bike mechanic. It seems weird that you have had to go back 5 years into Hambini's history to find something wrong. Greasing the bearing seating is optional. I apply a very small amount. The grease shown in the mountain bike video was excessive. That much grease is a great muck accumulator.
So you do use grease? So do I. So what’s your argument here? Hambini wasn’t wrong because? It’s only optional if you want the bearings to rust and you want to do a bad job. Everything he did during the video was completely wrong and every justification for doing it in his recent video was a bare faced lie. When you have been a bike mechanic as long as me and serviced as many bikes you would be able to see his lies more easily.
@@reginaldscot165 I'm not making an argument. I am leaving a comment. That, with the exchange between the two of you, you both seem to make a lot of mistakes. With the mistakes that Hambini has pointed out about you, I wouldn't use you as a bike mechanic. On the flip side, the five year old video of Hambini's bodgey skills is unrepresentative of his current skills. I would also not use him as a bike mechanic as he doesn't look after his own bikes. However he is an expert at bottom Brackets. I would consider sending my frame to him, if it had a major BB problem. So, you seem to be the slightly better (or less bad) general bike mechanic, but he is far superior in the BB repair area.
So it's OK to spray your frame with GT85 (with all its rough aditivites) all over but not good to put a small amount of grease between the bearing and the frame... blimey!
Well now I feel not do bad, working on my bikes like I am not sure what I am doing. Still doing better job than aero engineer... Thanks for video, I really liked that video.
I've not seen this video of his before, and I do admit I've followed him for some time. But it does go to show that just because someone works with stringent tolerances on components in a different field altogether, doesn't mean that he's a competent BIKE mechanic, or any good at dealing with bikes specifically... Surely his video is a skit?? There must be a disclaimer somewhere?
That was appalling. For starters, how did his bike get into that state in the first place! I'm an engineer (software admittedly) but I take pride in the machines I work on I put grease everywhere - just basic lithium grease. Additionally, I did not see any evidence of him checking the condition of the carbon fork - e.g. for cracks, scratches, or the ring of death. I reckon that bike was left out in the rain. Methinks "Brought to you by Hambini, aged 5" could be a Freudian slip.
@@sturidesbikesReally? I'll tell you the truth, the one who responsible are _-censored-_ They're moved the bikes production to far east with slave wages and Chinese tofu level engineers for their profit and greediness.
@@reginaldscot165 the video was bad, but I must admit he is brilliant in certain areas. Def a BB specialist, and he does point out how crap QC is with carbon crap.
I was not surprised you made a video on this. I missed that vid, but I recently saw it. You made a great analysis of his awful. 4:27 Yep '''spray it every where'' Ok mr Hambini, even on the brakes so they don't work, tyres too? 6:10 He even makes the job harder by having the ratchet head over the top tupe and the bar turned. This makes zero sense, probably just for the camera, but still just reposition the camera then. Showing a bad technique is not good. At least without a warning. I was not surprised you mentioned it later at 7:37.
I appreciate the first video I saw of you debunking Hambini about striking a bearing vs using a puller but watching this video? Oh man, saltiness is in the video. You are just going overboard, to the point that I can also smell jelousy. Stop using Hambini on your videos, instead make videos that contradict him and other "wrong" mechanics without mentioning their name, make your own name without riding someone else's name. Disclaimer: I am not a Hambini fan, I am not an expert(that is I'm watching bike videos) and English is not my native language but this will be the last time I will watch your videos. I did not even finish watching this video because all I can feel is saltiness. Good luck.
I'm an Aerospace Engineer with vast experience with the big players. I've always been suspicious of your Hambini, Peak Torque experts. It is extremely rare to work and gain working knowledge in a wide range of speciality areas, typically Manufacturing, Composites, Design, Stress, Aerodynamics, Fluid Mechanics etc. They are distinct roles in themselves and you don't move between them and definately not expert in all of them.....
They know everything because they read it in a book. Crossing the bridge between the abstract and the practical reality becomes an impossible challenge when the mind is stuck in the knowledge trap. The placebo of mental ascent has deceived the soul. They 'say', but they 'do not'. Woe unto them.
"Composites, Design, Stress, Aerodynamics, Fluid Mechanics etc." - You just listed an array of topics a single aerospace engineer is expected to have, at the very least, working proficiency in. Some specialize, but implying that an aerospace engineer worth his salt, especially one with experience investigating incidents shouldn't be expected to have knowledge in these areas makes me doubt your claim to be an Engineer. If we assume you are right that he can't know all these things, what the hell makes aerospace engineers different from Mechanical engineers then? Hambi/Peak Torque have only made basic engineering assertions that any engineer should know including you if you are one.
@@moshet842 Unfortunately modern education has produced a generation of 'knowers' and 'sayers', just don't let them 'do' anything because they'll mess it right up.
remember who Hambini or Sanjeev really is: a PhD in Aerodynamics, Lead engineer from a reputable company, 25+ years experience in the job of aerospace engineering, selling bicycle parts on his UA-cam channel under as chosen synonom 'Hambini'. If anything above written sounds strange to you, especially the part with PhD and selling bicycle parts: congratulations! You passed the red flag test of how to spot a con artist. Well done. Nothing wrong about selling bicycle parts, but things Hambini claim he is and thing he does on YT doesn't match together.
Hambini is right on many accounts and he has a courage for calling out the bike industry that went in deranged mode recently with its unnecessary tech nobody has asked for and insane prices... but then Hambini is absolutely shite bike wrench and I would not let him work on my trusty steel bikes let alone carbon fiber ones... My aluminum seatpost gets off from the steel frame easier than he can drop his carbon fiber fork. Go figure...
Ha ha yeah, you clearly know what you are doing. I think many people are brave enough to call out the bike industry, it’s not like calling out the communist government or something. 🤣
Talking about taking the piss. George, please can you tell us how much you trust the quality of Shimano cranks even though Shimano admitted they'd fooktup?
You still whining about that nonsense 😂 love my Shimano cranks I’m still riding all the cranks listed in the date range/codes. Still a non-issue people like you made a big deal out of nothing. You’re never going to take the piss out of me on this non-issue. Carry on dude find someone else to troll. 🧌 😂
Oh wait there’s more if you watch my latest video I used a Shimano crank to build a Frankenbike 11/12 speed bike. AND I just built matching bikes for Jess and I with Shimano R9100 groupsets including guess what Shimano Cranksets. It’s a non-issue for me.

He published a reaming of this video where he claims his top cap has a threaded collar. That does not make any sense to me. Why would a top cap be threaded. I commented and he replied. He wrote wits obvious that it's threaded. Strange. Nothing obvious.
He wrote this: Hambini wrote: ''It's plainly obvious it's threaded. Saying corrosion was holding it together was the most stupid thing I have heard for some time. I can't believe a "pro" mechanic said that. '' ''Providing you can generate the clamping force, the bearings don't care. I guess the ITM guy didn't care about having logos lining up.'' I will wait and see what ITM(ITALMANUBRI) says in the message I sendt them. If their contact form worked. @@reginaldscot165
They received my email. I will come back with what they wrote. But they needed clarification, as they did not understand my question. So waiting for an answer. @@reginaldscot165
My first thought was his actions were just plain inexperience. But I think there's actual ill in his skill and a blithe desire to beat unmerciful on carbon components. People have been slapping things together for years I suppose. But it's a strong reminder why I do all my own work. If I get stranded in the boonies or late for work, I have only myself to blame.
14.23 whats up with that tyre the rubber looks all deformed that bike Looks like a barn find but hes got the garmin on it so is this a daily driver? No i hope not its someone who doesn't appreciate what they have!
What a complet bodge job. The kind of repair you do at the side of the road in an emergency. All in a hurry, no grease, brute force. Apparently the top cap has an integrated bolt. Hambini got himself a bit cocky. You known you're going to be watched by thousands of people. He should've informed himself a bit better and tried to do a more professional job if his intention was to educate people. I can't understand it unless he was asking to get rimmed 😅😂
@@reginaldscot165 would be great to see you rip him a new one. That guy is next level of self love and lack of basic common sense. He's most famous for stating that manufacturers never build tolerances into parts, e.g. max torque or max pressures are hard limits that if exceeded will lead to disaster that's why he'd rather damage customers' parts by checking for play than follow manufacturers instructions and torque up to recommended spec (i.e. he adds his own made up tolerance). He typically never responds when you point out his lack of basic technical knowledge e.g. Continental test their tyres at 2x recommended max pressures.
Well, Reginald you seem to have exposed Hambini as a pretty sloppy bike mechanic, the level of work expected from a 5 year old and as an added bonus, you've made a pretty entertaining enemy, I can't wait for the next installment.
Thanks for posting. This video is shocking! Not even my winter bike, that sees both snow, rain and sweat from indoor training, have ever had corroded steerer tube bearings. The handling of this bike is pure foolish. I kinda expected he would put it down on the handlebar/saddle at some point.
An engineer designs stuff, a mechanic repairs it. Two different skill sets so I think it’s a bit of a cheap shot to slate him for being a bad mechanic.
@@reginaldscot165 hambini’s channel is about engineering, the few bits of wrenching are purely illustrative and aren’t meant to be a guide on how to work on your bike or show his mechanical skills. In life we sometimes do stuff we’re not particularly good at. You are pretty bad at communication yet you still engage in it. Grow up and accept the fact that you’re clearly just bitter about him being critical of your work.
I enjoy Hambini’s more academic videos/power points, he demonstrates he inherently understands stack tolerance issues, something most just do not get. He is definitely a smart “Engineer”. Most qualified BE, PHD “Engineers” go through a predominantly academic training route and hence commonly do not ever gain the soft skills and knowledge of those that go through a more practical route. This video should be used as a brilliant example of getting someone with the wrong training/experience doing a job. I hope Hambini takes the positives from your video in understanding that being a smart PHD person, commonly does not give you the soft Engineering skills. This is what apprentice training was for. Horses for Courses. For videos on more academic subjects. I smart PHD person is the Horse for the course. For videos on the soft aspects of basic bike maintenance, an experienced, thinking maintainer is the Horse for the course. Being wise in Engineering, is knowing you can learn something from everybody.🙂

You are welcome, he is not what he seems. 😳
3:05 white powder? for a minute I thought we were about to discover the source of Hambini’s weird erratic personality. A bit of Charlie
If he’s sniffing aluminium oxide it would definitely have some effect on his mental stability. 😂
Thanks for the informative video on what not to do on a headset service!
Well, you can thank Hambini for that. 😅😉
Another Hambini roast.
Standard engineering practise is to grease any metal/ composite interface/threads.
He may be an aerodynamicist or whatever as well as a plumber but not a mechanic I would trust.
Not sure what he is but I also don’t trust his work.
Just stumbled on this video, Reginald. Never seen the Hambini video before. I’d just like to say that the jury isn’t out! 😂 This is a genuine “how not to”.
Yes just do the opposite of what he recommends and it would be a better service. 😅
Wow, this video has just blown my mind! I had never seen that Hambini vid, but yikes 😳 I swear about 50% of steerer bearings out there are under-preloaded (loose), and about 40% are over-preloaded, leaving a sliver of bearings out there actually operating as they should be. That was painful watching Hambini cranking his up so tightly, and crazy to think that that same person actually designs and sells bearing systems (bottom brackets). Not only that, but he has taken on the mission of producing remedial bottom brackets to fix everyone else's flawed designs. That was an eye-opener!
If you think that was bad you should see my other videos on him… 😳
But only if you want to get more shocked. 😅
@@reginaldscot165 This was the third Hambini-bashing video of yours that I watched. One comment said that this headset vid of his might be from 7 years ago, so it's feasible that he's learnt a lot in those 7 years, but it's still surprising to see an engineer treating bearings and an assembly in this way. His unsympathetic use of hand tools is also concerning, but then I see a lot of engineers operating tools in this way! My experience is that it's rare for modern engineers to be good at the theoretical AND practical aspects of engineering, which seriously needs addressing. I can't blame you for meeting fire with fire after he tried to call you out. I hope you manage to continue keeping these vids more technically critical than personal and retalliatory 🙂
That video was gold dude... Looks like the aerospace oil imagineer got reamed !
Yes it was rather fun, pass it on for others to enjoy. 😁👍🏻
Ham could paraphrase Dr. McCoy's (Star Trek) favorite declaration: "Damn it Jim, I am an engineer, not a mechanic".
He could indeed. But McCoy would never try to demonstrate how to fix a warp core. 😉
I can feel your frustration. Reginald, and mine , too! Holly Chromoly!
Indeed! Thanks! 🙂
Excellent video focused on the facts rather than rants - subscribed !
Thank you I really appreciate that .🙂
Also, why did the compression plug have to come out, especially if your going to bash on the steerer? Leaving the compression plug installed at least means you're hitting metal and not raw unsuppored carbon. Also how he just keeps bashing it risking the compression ring to gouge into the steerer 🤦 Just a little tap to get some play and then push the steerer back up to release the compression ring from the bearing and the ring just slides off and the steerer drops.
Also just clamp the seat post and tilt the bike down and that way nothing can fall anyways.
I've never seen an "expert" litteraly get every step of the most basic maintenance task wrong 🤦
It’s totally insane, to think people consider him the “expert” on everything now. 🤔
was that hambini video a halloween video???
Arggg!
Maybe April 1st. 😂
Be thankful he's not working on handguns 😅
Yikes 😳
Serious question, Can you explain why you hold your Titanium bike in high acclaim when it has a defective bottom bracket? According to the SRAM specifications, your frame hole is too small. Do you feel that you ignore manufacturer data because you know better?
Not really a serious question is it old boy. 😉
It’s a PF30, in it is a PF30 BB with a 30mm spindle. It spins fine. 👍🏻
Stop trusting people who are dishonest. 😘
@@reginaldscot165 So you know better than the manufacturer?
@@reginaldscot165So, SRAM is dishonest? I mean the BB specs are on Sram website and on your video it shows your BB be undersized. So who is dishonest, you, Sram or hambini for pointing that out?
@@thedronescene7474 Reginald is too hurt to admit he has made a mistake. For all Hambini's failings, he readily admits his headset video was rubbish.
@@theillegalimmigrant9314 Exactly! Which is why Reginald should not be trusted. If he cant accept when he is wrong then no one should trust him.

The backwards brake pad is telling. As an engineer, I'm an electrical engineer, your job is ALL ABOUT DETAILS. Small details. Large details. All of them. The more critical the detail, the more attention you pay. If you're a good engineer, this mindset is ingrained into everything you do. If you're not a good engineer, well, you might mount brakes backwards.
Worrying isn’t it. 😳
We are all doing our best to service our bikes at home, it’s good to see others sometimes struggling as well w certain challenges and parts and have a debate on these technical issues 👍
👍🏻
You seem to like taking shots at him but as a point so does he to others. He puts his work out so it’s open to criticism, all is fair.
True. Agreed 👍🏻
Disagree! It’s the manner in which Hanbini takes his shots. Doesn’t need to use profanity all time. Shows his lack of maturity.
@@FL-ym6hmHe doesn't claim to be mature.
@@FL-ym6hm Which part of "by hambini aged 5" part did you miss?
If he's this wrong, it doesn't matter at all how polite he is. He's politely showing people how to mess up their 5 thousand dollar bikes
Specific greases and weights are needed for each application.
E.g ti prep for titanium etc.
Where 2 different metals contact each other there is galvanic corrosion.
Water and salt is the catalyst therfore cleaning and re-greasing is needed more in wet or dirty conditions.
This maybe stating the obvious but it is often neglected.
I totally agree. He recently started that he had never herd of corrosion with aluminium and stainless steel… can you believe that coming from an aerospace engineer?
@@reginaldscot165yikes, can you link where he says that? Find that pretty shocking
He is not the neatest mechanic/engineer but this service deserves a badge of dishonor; Sewage headset service by a 5 yrs old!
Agreed 👍🏻
That top cap is obviously threaded to the bolt.
Also, do you know any doctors who smoke or drink excessively? He may treat his own bikes carelessly but that has no bearing on his competence.
That was a very poor attempt to defend his incompetence. 😂 and no you are wrong about the top cap but nice try. 👌🏻☺️
@@reginaldscot165Also I live in Norway rid eon salty roads no issues with top cap, I out a bit of grease at the bottom threads and underneath the bolt head. Never gets stuck. To me it looks like months of corrosion by sweat from his head. I ride a MTB so would not be in that position often, but simply cleaning the bike after each ride would help. It's so quick and easy to do. Only times I don't do it is if my back is really bad. He talks about proof about grease attacking the resin but where is it? Where's the proof of the threaded cap? 😁
Crazy state of the bike….
I’ve seen worse… unfortunately. 🤣
sorry to brake your logic but your brake on pushing on the bolt straight.. you are wrong.
if you have a rubber, tightened at the "entrance" of the friction force, as you brake harder, the tension on the brake pad will elongate it thin it out (reducing the thickness of the pad), and also start tearing it. the bolt of the brake pad is not meant to hold the braking force, but just the rubber insert not to fall out.
if you have it as shown in Hambinies video, you will have compression in the direction of braking force, making the pad thicker and also it will be butting up against the insert holder. also you will have more pat material where your biggest braking force is generated...
from most of the comments it seams that you are trying to find a way to make it look worse than maybe it is. 1st of, you assume the video is uncut and every part of the video, blt not being tight is as is... the wheel was supported by the tool drawer from underneeth... which you would see maybe...
but to your credit you have a lot of good points and explanation
Sorry I found this comment impossible to understand. I’m guessing your first language is not English?
If you can get a friend who speaks better English to help with making this comment clearer I will happily try to read it again. 👍🏻 Or maybe try Google translate, that seems to work well for me.
All the best! 👍🏻

I as a rule dont like people point scoring off each other, I would never criticise another persons video. However I was pretty shocked at the poor practice in this video. Its certainly not the way I work. I also cringed at the top cap being tightened, that was pretty much the worst thing on the video.
This is after all a pretty simple job for a decent bike mechanic 👍
But is it a simple job for a aerospace engineer? 😂
Well normally I wouldn’t “point score” but he made the mistake of lying about me and my tools in his video so now the gloves are off! 😉
@@reginaldscot165“…the gloves are off“ - understandably.
Bambini as a bike mechanic makes a good comedian 🤣🤣🤣🤣🤣 I think he did a perfect video on how not to do it🤡
Agreed 👍🏻
7:51 After sending a clarification I did not get any answer from ITM, so I tried to send more info trying to explain what I'm asking, I referenced this video, and shared a link to it, a screen shot.
But still no answer. It's simple, thing to answer, is the stem cap threaded?
only two options Yes, No. Strange they can't answer a simple question.
I’d bet money it’s not, I found some photos online of the cap and it looks like every other design out there. The only thread one I’ve seen is the FSA one designed for cannondale about 6 years ago. It looks very different.
@@reginaldscot165Update: I sent them a new request, still no answer. Maybe they are ignoring me this time. I don't know. Maybe they are busy who knows.
It would be best for them to give a clear answer or even response to Hambini's video if Hambini is wrong. But yes I saw the pictures of it it looks like any compression plug top cap. Or post more pictures.
You'd think for an engineer he'd have the correct tools
For working on a bike! Like the headset remover tools ive seen enough 😂
He has the tools, just doesn’t use them… and when he does he uses them wrong. 😢
Thoughts on the Hambini Christmas Reaming? 😂
Not seen it, busy with family. ❤️🙂
Proper reaming
Full ream.
There's one subtle issue glossed over in this video that is worth mentioning - the clamp bolts on the stem should be tightened and loosened incrementally, alternating between the 2 bolts, in order to ensure the loading on the clamp is reasonably even from top to bottom at all times. A quick thought experiment to explain why - If both bolts are initially evenly tightened and one is loosened completely, then the remaining tension (Which is more than the tension either bolt was carrying while both were tight) is carried entirely by the remaining bolt, leaving the bolt and more importantly the clamp loaded significantly more than they were when both bolts were tight. Similarly, when tightening the bolts, if you tighten one bolt up to the recommended torque and then tighten the second one, also to the recommended torque, the first bolt will now be loose. This is not mentioned even in the official instructions for installing a lot of parts with paired bolts on the same clamp, so you can follow the official installation procedure to the letter, using a torque wrench and still have a dangerously installed stem with a loose stem bolt afterwards.
A scenario where this is even more important is on Hollowtech II crank pinch bolts, where the bolts are even closer together and in the much stiffer clamp at the end of the crank. It takes a little longer to tighten and loosen paired bolts like this (Especially on cranks where you usually have to spin the cranks 180 degrees for access each time you switch bolt), but at least you can be sure they are sharing the load evenly and the part is firstly clamping firmly enough to stay in place and secondly that the stress on the part is carried evenly across the clamp as per the part's design.
Speaking as both a very well qualified mechanical engineer and someone who worked on and off for over a decade as a bike mechanic, that Hambini video is absolutely shocking from both sides of the fence.
One trick I have seen, and even occasionally used, with GT85/WD40 is when MTBing in extremely muddy conditions is that spraying the downtube and chainstays with WD40 just before going out riding in thick mud does stop mud sticking to the frame, for a while at least.
Excellent comment and a very interesting point about the bolt tightening process. I must admit that I do know that you should follow that protocol, but sometimes I don’t… for the cranks I almost always do, it’s become second nature by this point.
Thank you for the detailed explanation.
Always good to hear from an expert. 🙏🏻🙂
Shimano manual for their 105/Ultegra/DA groupsets does say the tightening of those crank arm pinch bolts must be done incrementally. I always initially use just an allen key for the first coupe turns until the second bolt stops getting loose when I turn the other one, then switch to a torque spanner and do them up alternately to 3/6/9 and finally 12Nm. For stem face plates where there are mostly 4 bolts the tightening is done incrementally in a diagonal pattern too.
He was pretty quick to post a reply video, slamming your titanium bottom bracket description.
Must have touched a nerve 😅
The fact Reginald was so wrong about the top cap makes him look a bit stupid though, you have to admit no?

I hope so! 😅
When I was doing q group project as part of my degree, I had one guy complain about the module leader. I believe his exact words were "What does he expect me to do? I'm not an engineer!". This is a final year student, mind!
Anyway, that's when it dawned on me that he was only there to please his parents. Absolutely zero passion for the craft. I wouldn't be surprised it this idiot turns out to have been the same. "Engineer" in name only.
Good call. 👍🏻
This video needs some kind of content warning. Watching that bike getting that treatment has left me traumatized. And what's going on with that bar tape?
I’m sorry, I really should have considered that! 😅
Please, don't get too harsh with this 5 yrs old engineer and his beloved hairdryer. 🙏🏻
His hairdryer? 😁 that’s a fun fetish. 😉
He went in dry 😂
My days.
That’s what she said…
The front wheel was not removed for obvious reasons, it was seized in..
Ha ha ha 😅
To be fair to Hambini, that video appears to be from 2017. His maintenance skills might have improved a bit since then.
That’s true… but he is trying to show people how to do it. 🫢
so why doesn't he remove that video and make one that shows the right way to fit new headset bearings?
I hope so, for the sake of the aerospace industry 😁
Because he believes he does the job righr.
OMG what did I just watch? This is even worst then a novice diy!! The brake pads In reverse, no proper tools , the corrosion! Not removing the wheels , the bar tapes , clamping on the top frames , not putting grease etc etc . This is aerospace standard!
CFRP is made of uh... carbon, and epoxy. That's it. Nothing overly complicated, nor all that chemically sensitive.
You can manufacture your parts on the cheap, in which case they will kind of suck, or you can spend the big money and do it properly, in which case you'll get something reasonably skookum (though still ill-suited for making bike frames out of; or deep ocean subs). Either way, chemically they're about identical. In both cases I don't see how regular ol' water resistant grease will do anything nasty.
Agreed 👍🏻
For the life of me, I don't understand why he didn't remove the front wheel, before removing the fork... I'm not skillful in anything,and I can be a bit of...cluts😅 but I would definitely remove the wheel first, before removing the fork,to be serviced,greaced, cleaned, whatever...
Why he didn't loosen the screws,when removing the stem... Again...idk😅
And that squeaking sound when installing the stem on the steerer, I mean...why making it harder than it has to be..And no lubricant of whatsoever????? Man..
And... just because someone is highly educated engineer, doesn't mean he's good with tools,or just plain old bike service! We learn..!😅😊

True 👍🏻
I know a lot of engineers. They know the Theory with no practical application. It’s a rare element where both meet. I worked in the mechanical hands on realm for years then got my degree.
Spraying your whole bike with GT85 makes it faster when braking!
So true 😅
It’s not just road salt, Hambini lives close to the sea, in the well known aerospace capital of the UK, Grimsby😀 That regular ride to ‘the oil refinery’ exposes the bike to wind blown salty sand from the Humber estuary. A few weeks commuting in those conditions and any bike will experience corrosion. Grease would indeed help, GT85, a more expensive version of WD40 aka kerosine with added teflon doesn’t.
I also live by the sea in a very humid climate, my bikes don’t look like that… 😐
😉
I don't think so. I lived on the coast for several years and routinely rode parallel with the coast with the wind blowing from the water. I've never had anything nearly as bad as that.
Obviously your just a part timer@@reginaldscot165
It's not quite the same as WD40. GT85 contains PTFE which acts as a lubricant. In fact it's often advertised as a 'bike lubricant' although I doubt they intend it for bearings which are more appropriate with grease.
For a general frame protector (steel) I use furniture polish, in other words wax. It's not long lasting so it does need to be done on a regular basis.
@@vihuelamig I guess you shouldn't be spraying anything like WD40 or GT85 all over bearings as it'll dissolve the grease and you'll be left with whatever light lubrication it provides (i.e. not enough for bearings long term). If GT85 is sold as a bike lubricant I guess they would mean for the chain, cassette and so on.
30:27 my ears hurt listening to that squeaking sound. Damn that bike is screaming for help. He tightened that top cap way too tight.
Totally agree. What’s crazy is some of his fans try to pretend everything here is totally fine. Just like the meme of the dog in the burning house: “this is fine.” 😆
I am a complete amateur bike mechanic but have successfully looked after my 4 bikes for years now. I would never count myself as an expert but this clown does ?? When he preloaded his top cap i nearly screamed out. U need to just take the play out the system then maybe an extra quarter of a turn for luck. Technically u can remove the top cap once the stem bolts have been tightened up but I wouldn't. I would never have done that even at the beginning of my maintenance journey. And the wooden mallet. Wtaf 😅. I've heard mapdec raving about hambini and this is the man himself ? No thank you won't be listening to his opinion about anything
Yes you are a much better mechanic. I can bet money on that! 😅
I have never had to bang out my fork. Maybe a soft tap from my hand, but never had to bang on it like like that. I have a friend who owns a bike shop. She has a "wall of shame". His headset would go onto that wall. And who works on the fork and doesn't remove the wheel?
Sounds like your headset is in good condition. 😁👍🏻
To be fair, that does look like how a 5 year old would service a headset.
I think that’s an insult to the intelligence of 5 year olds.😅
Wow, I like watching Hambini but this was painful. How can he do so many things wrong in what is a very simple job.
Good question, maybe he isn’t very good at mechanical things? I also used to watch his channel, until he decided to completely lie about me and my tools. 🤷🏻♂️

trying to go head to head with Hambini is a bad idea
I disagree, it’s amusing and very successful. 😉
I had missed this one... Oh my god, poor bike!!!
Needs to be rescued like a puppy that’s being abused by its owner. 😢
Yes, this is a really strange thing what Hambini is doing here. Especially when you know how much precision and meticulousness he puts into his bottom brackets (of which i got a PF30, that works very well). Besides - i am a very thorough „greaser“ myself. I grease literally almost ANY screw on my bikes. Most important: The pedal axis screws! I had a case some time ago with a so-called bike „designer“ who sold me a bike where he had installed the pedals without any grease. It was almost impossible to loosen them later on. Never forget to put LOTS of grease on those threads…
Grease is almost always a good idea, certainly in bike terms. I think the precision of his BBs is over complemented, especially when you consider it’s the very expensive CNC machines at his workplace that he uses for free to make his BBs. When you have industrial grade programmable equipment you didn’t pay for it’s very easy to make precise products. I know this from personal experience: I used to work with industrial welding robots. Now personally I’m terrible at hand welding, I can do it, but I’m just awful. However, when I plug a few numbers into a welding program for a robot that robots makes some beautiful welds that out class the work of a professional hand welder with 20 years experience! Hambini is the same, we see in this video that he is just awful with his hands, not even capable of the most basic maintenance tasks. But, he puts some numbers into a programmable industrial machine and then all of a sudden everyone is complementing him on his work. 😂
his bike is an absolute mess, wouldn't want to own that bike even if you gave it to me for free

Whose bike was it? His own?

Reginald, may I ask for advice? I got a Triban RC120 for free, it's brand new and I liked it. Planning to do some upgrade to 105 groupset, what are your thoughts? What would you do? I also will upgrade tires and little things like carbon seatpost and stem...
That’s awesome!

Tyres first, spend as much as you can afford on hood tyres. My personal favourite is the conti 4 seasons.

The rest I mostly unimportant to be honest. Just have fun at that stage. Tape would be next cheapest, wheels the best bang for your performance buck. 🙂👍🏻
From viewing this video of his, he looks like an amateur bike mechanic. But many of your criticism of him in your video show that you are often wrong as well (from his response video), and yet you claim to be a trained bike mechanic.
It seems weird that you have had to go back 5 years into Hambini's history to find something wrong.
Greasing the bearing seating is optional. I apply a very small amount. The grease shown in the mountain bike video was excessive. That much grease is a great muck accumulator.
So you do use grease? So do I. So what’s your argument here? Hambini wasn’t wrong because? It’s only optional if you want the bearings to rust and you want to do a bad job.
Everything he did during the video was completely wrong and every justification for doing it in his recent video was a bare faced lie. When you have been a bike mechanic as long as me and serviced as many bikes you would be able to see his lies more easily.
@@reginaldscot165
I'm not making an argument. I am leaving a comment. That, with the exchange between the two of you, you both seem to make a lot of mistakes.
With the mistakes that Hambini has pointed out about you, I wouldn't use you as a bike mechanic.
On the flip side, the five year old video of Hambini's bodgey skills is unrepresentative of his current skills. I would also not use him as a bike mechanic as he doesn't look after his own bikes. However he is an expert at bottom Brackets. I would consider sending my frame to him, if it had a major BB problem.
So, you seem to be the slightly better (or less bad) general bike mechanic, but he is far superior in the BB repair area.
So it's OK to spray your frame with GT85 (with all its rough aditivites) all over but not good to put a small amount of grease between the bearing and the frame... blimey!
Logical reasoning. 👍🏻🙂
Never seen a Hambini video before. He appears to be quite clumsy
You are lucky. 😅

I've not seen this video of his before, and I do admit I've followed him for some time. But it does go to show that just because someone works with stringent tolerances on components in a different field altogether, doesn't mean that he's a competent BIKE mechanic, or any good at dealing with bikes specifically...
Surely his video is a skit?? There must be a disclaimer somewhere?
He certainly has not admitted it was a troll. In fact he defended the video by saying “I don’t care about my bike.”

That ratchet head resting on the frame...................mmmmmmmmmmmmmmmnnnnnnnnnnngggggggggggghhhhhhhhh
😳
That was appalling. For starters, how did his bike get into that state in the first place! I'm an engineer (software admittedly) but I take pride in the machines I work on I put grease everywhere - just basic lithium grease. Additionally, I did not see any evidence of him checking the condition of the carbon fork - e.g. for cracks, scratches, or the ring of death.
I reckon that bike was left out in the rain. Methinks "Brought to you by Hambini, aged 5" could be a Freudian slip.
Yes it was not well looked after. Im not trusting of people who don’t take care of their equipment.

6:10 He even makes the job harder by having the ratchet head over the top tupe and the bar turned. This makes zero sense, probably just for the camera, but still just reposition the camera then. Showing a bad technique is not good. At least without a warning. I was not surprised you mentioned it later at 7:37.

I appreciate the first video I saw of you debunking Hambini about striking a bearing vs using a puller but watching this video? Oh man, saltiness is in the video. You are just going overboard, to the point that I can also smell jelousy. Stop using Hambini on your videos, instead make videos that contradict him and other "wrong" mechanics without mentioning their name, make your own name without riding someone else's name.

I'm an Aerospace Engineer with vast experience with the big players. I've always been suspicious of your Hambini, Peak Torque experts. It is extremely rare to work and gain working knowledge in a wide range of speciality areas, typically Manufacturing, Composites, Design, Stress, Aerodynamics, Fluid Mechanics etc. They are distinct roles in themselves and you don't move between them and definately not expert in all of them.....
I was also considering that, seems very odd to me to be the one stop shop for all things engineering?
They know everything because they read it in a book. Crossing the bridge between the abstract and the practical reality becomes an impossible challenge when the mind is stuck in the knowledge trap. The placebo of mental ascent has deceived the soul. They 'say', but they 'do not'. Woe unto them.
"Composites, Design, Stress, Aerodynamics, Fluid Mechanics etc."
- You just listed an array of topics a single aerospace engineer is expected to have, at the very least, working proficiency in. Some specialize, but implying that an aerospace engineer worth his salt, especially one with experience investigating incidents shouldn't be expected to have knowledge in these areas makes me doubt your claim to be an Engineer. If we assume you are right that he can't know all these things, what the hell makes aerospace engineers different from Mechanical engineers then?

Lets assume he is in his 40s. Thats a reasonable assumption based on his appearance. 25 years of experience??😅😅😅😅
Genuinely can't work out if he's trolling or not
Ha ha I think not… but if he is it’s a massive troll. 😅
As a bike mechanic i'm crying as his bike is. That is painfull to watch 😢😢😢
I also felt pain watching it…
Hambini is right on many accounts and he has a courage for calling out the bike industry that went in deranged mode recently with its unnecessary tech nobody has asked for and insane prices... but then Hambini is absolutely shite bike wrench and I would not let him work on my trusty steel bikes let alone carbon fiber ones... My aluminum seatpost gets off from the steel frame easier than he can drop his carbon fiber fork. Go figure...
Ha ha yeah, you clearly know what you are doing. I think many people are brave enough to call out the bike industry, it’s not like calling out the communist government or something. 🤣
Taking the piss out of Hambini? That was fun 🤩
Wasn’t it! Must be bad for us. 😅
Talking about taking the piss. George, please can you tell us how much you trust the quality of Shimano cranks even though Shimano admitted they'd fooktup?
You still whining about that nonsense 😂 love my Shimano cranks I’m still riding all the cranks listed in the date range/codes. Still a non-issue people like you made a big deal out of nothing. You’re never going to take the piss out of me on this non-issue. Carry on dude find someone else to troll. 🧌 😂
Oh wait there’s more if you watch my latest video I used a Shimano crank to build a Frankenbike 11/12 speed bike. AND I just built matching bikes for Jess and I with Shimano R9100 groupsets including guess what Shimano Cranksets. It’s a non-issue for me.
@@SeeYouUpTheRoad luckily to those in charge of Shimano (even though they denied it for years) and anyone with working brain, it is an issue. I'm glad I unsubscribed.
So awesome love all your vids, you dont see this kind of stuff from bigger youtubers like gcn. Happy holidays!❤
Thank you so much! That means a lot to me. ❤️🙏🏻
Pixie dust ALWAYS works!!!!😊😊😊
Well the Muc-off pixie dust normally turns to a goopy mess after a few days. I much prefer the Morgan Blue blend of Pixie dust and graphite powder. 😉
whoops! - i actually meant REAL pixie dust from fairies and pixies!! - i'd no idea there was any product ripping off the jolly sprinkles from the magical world!! 😊😊😊@@reginaldscot165
hahahaha - d'ya mean some (clowns) actually called products Pixie Dust!!!!!???? - i actually meant the stuff fairies n pixies sprinkle on things with their stars and magic wands.... 😊😊😊 on a more serious note - ive used graphite on some extreme applications (hot, high pressure, hi revs in excess 100k rpm etc) with great results - its astoundingly good for plastic on plastic rotation and reciprocation too. on bikes i use jst normal stuff - no 'bike' specialised and never had lube or corrosion probs in over 60 yrs biking!! ive watched a good few of u r vids and like u r approach to engineering - use of pullers and pushers - only thing ive ever hammered and then only with a backing dollie was cotter pins - the never to be missed total pia bike bits from the distant past.....@@reginaldscot165
He published a reaming of this video where he claims his top cap has a threaded collar. That does not make any sense to me. Why would a top cap be threaded.
I commented and he replied. He wrote wits obvious that it's threaded. Strange. Nothing obvious.
We love for him to prove that. It doesn't really make sense but it's a weird headset.
Yes well the logical and simple answer Is he’s lying. 😂
He wrote this:
Hambini wrote: ''It's plainly obvious it's threaded. Saying corrosion was holding it together was the most stupid thing I have heard for some time. I can't believe a "pro" mechanic said that. ''
''Providing you can generate the clamping force, the bearings don't care. I guess the ITM guy didn't care about having logos lining up.''
I will wait and see what ITM(ITALMANUBRI) says in the message I sendt them. If their contact form worked.
@@reginaldscot165
They received my email. I will come back with what they wrote. But they needed clarification, as they did not understand my question. So waiting for an answer. @@reginaldscot165
I sent ITM another email. lining to this video and a screenshot. @@reginaldscot165
My first thought was his actions were just plain inexperience. But I think there's actual ill in his skill and a blithe desire to beat unmerciful on carbon components. People have been slapping things together for years I suppose. But it's a strong reminder why I do all my own work. If I get stranded in the boonies or late for work, I have only myself to blame.
Good comment. 👍🏻
14.23 whats up with that tyre the rubber looks all deformed that bike
Looks like a barn find but hes got the garmin on it so is this a daily driver? No i hope not its someone who doesn't appreciate what they have!
I didn’t notice the rubber. 😳
Have you tried to pull off a stem on a specialized? Even with the bolts out, it's tight. You need to critique Sam Pilgrim's work.
Yes I have. (Not a Specialized) I will check him out. (I literally can’t imagine anything worse than what I’m seeing here.)
Never had a problem removing any stem from any Specialized.
That rust in that steering is exactly what GT 85 leaves for you in winter months! Don't do it!
Yes it’s not the best idea.
What a complet bodge job. The kind of repair you do at the side of the road in an emergency. All in a hurry, no grease, brute force. Apparently the top cap has an integrated bolt. Hambini got himself a bit cocky. You known you're going to be watched by thousands of people. He should've informed himself a bit better and tried to do a more professional job if his intention was to educate people. I can't understand it unless he was asking to get rimmed 😅😂
That bit about the “threaded bolt” is total BS 😂 He’s just lying again. 🤷🏻♂️
I wonder if Hambini applied for the vacancy with Paul at Mapdec? 😮
Ha ha I was thinking of doing one of his videos next. ☺️
@@reginaldscot165 tread carefully there... His approach to bike maintenance is the polar opposite to Mr H.. 🥰
@@reginaldscot165 would be great to see you rip him a new one. That guy is next level of self love and lack of basic common sense. He's most famous for stating that manufacturers never build tolerances into parts, e.g. max torque or max pressures are hard limits that if exceeded will lead to disaster that's why he'd rather damage customers' parts by checking for play than follow manufacturers instructions and torque up to recommended spec (i.e. he adds his own made up tolerance). He typically never responds when you point out his lack of basic technical knowledge e.g. Continental test their tyres at 2x recommended max pressures.
Well, Reginald you seem to have exposed Hambini as a pretty sloppy bike mechanic, the level of work expected from a 5 year old and as an added bonus, you've made a pretty entertaining enemy, I can't wait for the next installment.
Well, at least you noticed. Some people can watch the same video and see nothing wrong. 😅
No grease in the bearing steerer wtf!
I know right! 🤨
i did cycling years. and i never seen bike look like that. why so dirty. i doubt mechanic bike look like that.
True 👍🏻
Thanks for posting. This video is shocking! Not even my winter bike, that sees both snow, rain and sweat from indoor training, have ever had corroded steerer tube bearings. The handling of this bike is pure foolish. I kinda expected he would put it down on the handlebar/saddle at some point.
Thank you. Yes it is shocking.
Wow, I wouldn't treat my hack bike with so much disrespect! It's obvious he hasn't got a clue.
Shocking isn’t it. 😱
An engineer designs stuff, a mechanic repairs it. Two different skill sets so I think it’s a bit of a cheap shot to slate him for being a bad mechanic.
I’m no good as a welder. I’m terrible at it. You don’t see me making videos on how to weld something.
Do you understand?
@@reginaldscot165 hambini’s channel is about engineering, the few bits of wrenching are purely illustrative and aren’t meant to be a guide on how to work on your bike or show his mechanical skills.
In life we sometimes do stuff we’re not particularly good at. You are pretty bad at communication yet you still engage in it. Grow up and accept the fact that you’re clearly just bitter about him being critical of your work.
I enjoy Hambini’s more academic videos/power points, he demonstrates he inherently understands stack tolerance issues, something most just do not get. He is definitely a smart “Engineer”.
Most qualified BE, PHD “Engineers” go through a predominantly academic training route and hence commonly do not ever gain the soft skills and knowledge of those that go through a more practical route.
This video should be used as a brilliant example of getting someone with the wrong training/experience doing a job.
I hope Hambini takes the positives from your video in understanding that being a smart PHD person, commonly does not give you the soft Engineering skills. This is what apprentice training was for.
Horses for Courses.
For videos on more academic subjects. I smart PHD person is the Horse for the course.
For videos on the soft aspects of basic bike maintenance, an experienced, thinking maintainer is the Horse for the course.
Being wise in Engineering, is knowing you can learn something from everybody.🙂
Great comment 🙂👍🏻
