Two points to make on this video: 1 -- I'm surprised you didn't mention that he wasn't holding the calipers "square" to the bore of the BB shell? Even assuming he had the touch of a master, there is no way to obtain even a "relatively" accurate measurement on a bore with calipers unless the internal jaws are square with the bore. 2 - Not to nitpick (but I'll do it anyways), at 9:30 in the video you talk about setting "pre-load" on a Shimano crank (or others). Technically, I believe a better term would be: "adjusting end-play". The last thing anyone should be doing on crank bearings is pre-loading them axially. Even if end-play is adjusted to zero, it is technically still not pre-load. 👍🙂
The resolution of the calipers is 0.01 mm which is more than double to the machining tolerance of the bearings. No amount of experience can fix that. Calipers were never meant for precision measurement. Telescoping gage and micrometer would be so much better but he wouldn't know how.
To even measure hundreds with a caliper is... just because it says many numbers on the display, it doesn't mean that you are able to trust that it, A) measure correct, B) YOU holding it correct... As a 25year machinist, this makes me cry :) Use calipers to get the ballpark. Then use correct tools to confirm the measurements.

Hambini, I’ve really enjoyed your videos over the last few years but I have to say that ‘how to change a headset’ video was….well, let’s just say I would do a lot of things differently to the way you did them back then. Happy New Year anyway chap.
Hambini know best. For those who knows caliper well he can tell us that is a cheap caliper not fit to the measurement for three uncertainties. (1) +/- 0.1mm factory tolerance and (2) OD and ID jaws manufacturing offset to about +/- 0.05 to 0.1 mm. (3) Spring loaded skid pretension free play. What we have here is a press fit parts a BB shell. What else can we use? Experienced mechanics and engineers outside of a calibration lab often use two steps process. Use a good old mechanical caliper1 to contact “feel” the shell ID in step-1. Use a known good digital caliper2, set zero first then adjust it in multiple minute decrements until he gets the same frictional “feel” on ID previously reproduce that feel against the jaws in caliper2. Then record the display reading. Why not direct w/caliper2? Because we have rail to skid free play plus flex in the caliper which varies in proportion to the handling force during measurement.
LOL, maybe that's the bigger picture. Hambini and Reginald sitting there debating each other would be great entertainment! It'd be like Noel and Liam getting together 😀
Another funny and informative video Many people like me rely on mechanics as I'm likely to waste time and money diy-ing stuff but this makes me think again
I've taken my bike to a bikeshop very few times, one of the times they couldn't even cut the steerer straight, my mate also took his race bike to a big brand bike shop and in the service notes they said the chain was dry (the chain was waxed) and it looked as if they put some kind of mechanical grease on the chain meaning it had to be cleaned and waxed again. If you're actually into cycling and ride alot it will cost you far more money taking it to the bikeshop multiple times a year than it is to just buy the tools yourself and watch some youtube tutorials, and you don't have to worry about someone else messing with your bike because they have other ideas of what needs to be done or how it should be done. You can get all the tools including a bearing press and extractor for less than £100 so that'd pay for itself after a year.
Biggest issue I have with removing bearings, you NEVER re-use them so don't remove them until they are being changed. When that is happening, it doesn't matter if you use a puller or drift them out. As far as I'm aware, (plus over 50 years as a mechanic) you don't 'preload' deep row ball bearings but you do take the piss out of engineers who can't work on their own stuff because it's too difficult and only possible during assembly at the original factory (yet we manage to invent ways to fix the shit turned out without just buying new or sending it back)
17:28 threaded top cap? So bolt is threaded into the top cap? I've never heard of nor seen that. It should simply be a hole. The collar is normal, but threaded collar is not. I don't think that exists. I can't see a valid reason for threads there. The bolt is threaded of course as it goes into the compression plug. And yes using grease there is a good idea, of course no need do go cray, just a bit of grease to stop if from getting stuck. Only the bolt should move, thus no threads in the cap. Why is it threaded? I can't make sense of it.
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.
@@HambiniI've never seen ITM on anything. I checked dit out only found pics of compression plug and a stem. Seems like the brand does not exist anymore.
@@mtbboy1993 ITM stands for Italmanubri. It is an Italian brand that makes handlebars, stems and seatposts. Most Italian bikes in the past had something from ITM on them.
I knew about that kind of topcap because my Cannondale has one. It seems that it's a bit tougher to set preload accurately. The manual threatens warranty will be void if another compression plug is substituted. It's known that a Cannondale warranty is worth nothing. See the videos from another U Tuber with 3 replacement frames, the last one also purchased and defective at the steer tube top bearing seat. I don't expect anything from them, so it's not even registered! With it's oversized rotors I'm on my own anyway. At least the stem bolts had been torqued to spec on the carbon steer tube. Maybe it won't kill me this year! After all, none of this has the Schwinn stamp of approval!
Wonderful reaming😂 BUT there is such a thing like corrision between steel and Aluminium. It is not real corrosion but a white powderly Connection between the two materials after years of usage without removing the seatpost. Had several years ago a seatpost stuck to a frame and it was a pain in the *ss to save both. Happy new year,Sir🐷🍄🍾
Titanium's expansion is 0.00000714 meters per meter per degree C. So, a 50mm diameter tube heated by 20C would increase diameter by less than one hundredth of a mm. I doubt that will ever matter. Titanium has about half the expansion of steel for the same temperature rise.
Hi Hambini. I have a question technical questions about measuring BB30 (or similar) bores in frames. Do you prefer to use a telescopic gauge and an outside micrometer? An inside micrometer? Or you prefer to use cylindrical blocks used as no/go gauges? Additionally... how do you check the two bearing surfaces are concentric, and/or parallel?
Yea. He's a bit on the spectrum. On another note, I made a comment on a mapdec video about grease and carbon interfaces and got shot down in the replies (not by mapdec)
Cmon guys… this is just an old fashioned Pissing contest…may i suggest a livestream pissing contest 😂. The loser gets to apologize to David Arthur and say “All hail!” to Peak Torque..
Definitely an Aldi caliper I got the same one to start with last year but surprisingly very accurate! Still bought a better one anyway when funds were better but still look at the aldi one out curiosity to see how off to the expensive one and never been off yet so really can't knock it
11:49 looks like he used the correct tool. But the tool shown here won't work, bearings shown seem to be different. It clearly worked in his video. All you need is the correct tool. Yes if it's like you show here it won't work. 🤔
You hate criticism and you left out a lot of important parts, which proves you made one of the worst tutorial videos on the internet (headset video). It doesn't matter that it's your own bike and that was a few years ago. Any serious engineer should be ashamed of themselves
As far as the top cap and bolt goes, remove and tap the cap and separate because you do not want to tighten up with the cap bonded with the bolt, you want the cap separated from that motion when tightening up the bolt. Its just full of crap/dirt/gunk from you not being bothered about the weather with the bike. X

This Reggie is like that true crime UA-camr who constantly make videos about his obsession with Lucy Letby, even that he has attended her court cases and sentencing and now plans to attend her appeals
I watch both of you. I think you both have valid opinions. But that headset bearing video was a car crash. I was actually shocked that it was something you would have posted on here. I initially thought it might have been a wind up.
The thing is hambini is a well known personality, has a sizeable following and is at this point a 'brand.' No publicity is bad publicity and whoever Reginald is is just getting traffic by mentioning hambini.
Most people will only go there once. The guy is a complete plonker who seems to cater mostly the misty eyed fools that think road bikes peaked in the 90's and anything that isn't 11 speed 105 rim brake is over complicated and bougie. The epitome of "a little knowledge is a dangerous thing". I'm pretty sure that any half competent home mechanic knows more than he does about bikes.
No idea. Do you know? When I do frame corrections, I usually go for a 45.98 on the boring machine. The tricky bit is getting both sides aligned within range. Machining the hole is easy, getting them aligned is difficult.
@@Hambini no idea either. I end up having to enlarge the hole. Still experimenting with the best method to get some kind of alignment. I have rigged up a tia from the seatpost on a frame right now. Using a frame gage to get the centreline.
@@_Zane__ I usually use Dormer but that will be a custom size. I don't know if PF30 or BB386 was originally designed to be Hole basis or shaft basis, it's not clear.
He's taken a basic concept, that Carbon Dioxide is necessary for photosynthesis, and concluded that this means that climate change isn't real. That's like saying that drinking water is necessary for life on earth, therefore flooding is harmless
You're being a bit unfair with the alignment. That shell has been machined after welding to rectify the heat distortion. The evidence of that is it's thicker and thinner.
I went and watched his video on how to remove a bearing. I knew before i even clicked, what hes gonna say and he sure is. Grabbed blind bearing puller, overtightened it and used puller and not a slide hammer. I kinda agree if there is space to put that type of a bearing puller in and only slightly tighten it, but no chance. On that small size of a bearing with that small of chamfer, this puller aint grabbing nothing, untill you squeeze it. then in kinda ruins the point, since you are deforming bearing. If you were to cause damage that is definetly how. I myself would of knocked out with a punch too, or at least partially to properly engage puller and pulled it with a slide hammer, and not that dinky clamp screw type style, that is destined to marr hub surface and bend a spoke when it slips :) Also he is wearing nitrile gloves, well seasoned mechanic, that
Also valid point about grease. For the life of me couldn’t figure why bike “mechanics” grease sealed bearing in headtube and its inner and outer surfaces like its a motorcycle with 2 part bearing and separate cage with balls
The measurement of the bottom bracket with calipers is not accurate cause the caliper "fingers " are square so the actual dia would be slightly larger. ( I think you have mentioned this before ) .
They are actually sharp blades at least on good calipers, but its is near impossible to guarantee they are centred and perpendicular so calipers are at best good for a rough diam. To add to that, most cheap calipers under $250 or so do not have enough precision to measure a bearing bore though even if you did manage to pull a real number. 0.001" is about all you get form a basic mitutoyo with is not enough to accurately assess PF30 tolerance. If you have a $20 amazon type... 0.002" over 2 inches is dream land. It will tell you absolutely nothing.
Just goes to show any bloke can call themselves a bike mechanic. There is not governing body to confirm credentials (like engineering). Just like naturopaths call themselves Doctors - fukking joke!
Which governing body confirms engineering credentials ? I've had the dubious experience of working with a few Part21J, D.O. engineers and a CVE who were bordering on incompetent. A couple of them also held C.E. status .
@@Andy-co6pn I think the Euro Ing is a lot more rigorous than anything else. You need academic quals, then C.Eng and I think ti's 6 years more on that.
Bike mechanic: In Germany it's a trade, regulated by a body. Calling yourself that you're exposing yourself to fines. 'Engineer' however is regulated by law. You'd face criminal charges (Amtsanmaßung (for awarding it yourself), Betrug (fraud)) and civil charges (Verstoß gegen das Ingenieurgesetz), though usually "only" mid four-figure. Same goes for carrying the title but translated. You don't need any practice however, just a qualifying degree from a university.
im not here for the sarcasm, not really here for the engineering highlights, im here for the recommended advertisements in the captured UA-cam segments to learn more about the one who calls himself a magical hamster.
I can't help but notice how the chair keeps shaking throughout the video and can only assume Hambini shakes his legs like most of us Engineers or there's a hairdresser outside the video frame.
A good quality blind puller is perfectly capable of catching the radiused edge of a bearing inside a freehub with no protrusion past the radiused edge of the preload spacer. No mechanic would use the type of pullers you show in this video.
I have luck... bike mechanic removed bearings on my old alu wheelset with that odd dentist tool... So I would rather bring my Hypers to my dentist when needed - anyway, she is a psychopath, she says, when I come around. Thanks, Hambini, you saved my teeth (I don't care for old wheels).
This is what we all love... The Drama! Especially at Christmas time.. I subscribe to you both, just so I can see the too and fro of course. Happy Christmas to you Hambini, may all your pens be working, and your hairdresser aptly glazed. Godspeed you filthy 5 year old.
I use wax on parts I'm afraid will seize or corrode. Only grease or oil in sealed bearings. Seems like wax is more water proof and will last longer to which means better protection.
You shouldn't have brought up the subject of co2 given all the misinformation around the politicized subject of global warming/climate change. Just to inform you on how important co2 is to the environment and all life on earth, I submit the following facts, etc for your further reading: All life on the planet dies in a mass extinction event at co2 levels of 150 ppm , plants can no longer live below that level but levels below .03% would drastically reduce plant growth. At .08% co2 plant growth doubles, at .12% plant growth triples. However, not all plants use co2 the same way, type 3 plants groups(grasses, corn, etc) have only one pathway to use co2 and requires direct sunlight but type 4 plant groups have two pathways to utilize co2 (Deciduous trees) and do not require direct sunlight and convert 2x the amount of co2 to oxygen . Type 4 plant groups start being replaced by type 3 plants at co2 levels below .04%. .... With higher co2 levels comes stronger plants as well with reduced need for water, fertilizer, and pesticides. Runoff from big agra farming practices is polluting the planet and destroying our health (nutrient content and micro-nutrient content of fruits and vegetables is 75% lower than it was 100 years ago. The mass hysteria surrounding climate change/ global warming has ignored the issues that will kill off humanity 100 x faster than climate change ever could. Historically, of course, the planet's co2 levels have been over 8x higher than they are now and apparently the planet survived quite well.
Your a special kind of stupid aren’t you? Climate science has never disputed CO2’s role in the ecology of the planet. Your arguments are as irrelevant as the dickhead who was being reamed. Go and put on your tin foil hat…..wanker…

@@mrnobody9821 Maybe - But how many examples of poorly manufactured tubing do you see for anything else. This is expensive titanium where I would think high standards would be maintained by the maker of such an expensive metal.
You are correct.
@@moshet842 Happy New Year! Please see @reginaldscot165's response. It was his picture.
What is the reference of this ITM stem cap Hambini please?
No Idea, the video is 7 years old, the bike was bought in 2013 I think.
Hi Hambini, what tool and procedure would you please recommend for removing bearings from wheel hubs (front and rear)? Thanks
Your wheel hub manufacturer should answer this not this guy, who says he is not a bike mechanic - why do you need his input at all
Keep up the work Hambini, bell ends will be bell ends.
Merry Christmas Hambini.
I tune in for both. But mainly the learning.
Hi hambini, would you be releasing the lube comparisons video ?
Love you mate ,to be frank that headset video is hilarious.
Hambini, I’ve really enjoyed your videos over the last few years but I have to say that ‘how to change a headset’ video was….well, let’s just say I would do a lot of things differently to the way you did them back then. Happy New Year anyway chap.
I don't disagree with any of that. and I'm happy to accept when I make a mistake.
Hambini know best.
For those who knows caliper well he can tell us that is a cheap caliper not fit to the measurement for three uncertainties. (1) +/- 0.1mm factory tolerance and (2) OD and ID jaws manufacturing offset to about +/- 0.05 to 0.1 mm. (3) Spring loaded skid pretension free play. What we have here is a press fit parts a BB shell. What else can we use?
Experienced mechanics and engineers outside of a calibration lab often use two steps process. Use a good old mechanical caliper1 to contact “feel” the shell ID in step-1. Use a known good digital caliper2, set zero first then adjust it in multiple minute decrements until he gets the same frictional “feel” on ID previously reproduce that feel against the jaws in caliper2. Then record the display reading.
Why not direct w/caliper2? Because we have rail to skid free play plus flex in the caliper which varies in proportion to the handling force during measurement.
Hambini you should do more Livestreams. Maybe one together with that Guy Reginald
LOL, maybe that's the bigger picture. Hambini and Reginald sitting there debating each other would be great entertainment! It'd be like Noel and Liam getting together 😀
I have to laugh at people thinking calipers are accurate when you should be using micrometers
Yes, especially that apparently "high quality" piece of junk he is using.
Geezus... "Knob end" means something in British slang...and I'm not british
A little knowledge is a dangerous thing.
I think you'll find that Hambini has more than a little knowledge
Isn't it just a bit obvious I didn't mean Mr. H?
@@greggsenne1268 I think it's a bot
RS’s videos showed up in my feed a couple of months ago and to be honest he seemed like a whiney little girl
Come on Hambini. Your above this. You lost with the wheel bearing thing. This is petty.
Kudos to Reginald for willing to be screw from behind in order to gain a few views for his channel. You gotta do what you gotta do sometimes.
Keep reaming Hambini. This goose needs to be reamed.
Just like that headset. Give it some good mallet love.
Another funny and informative video
Many people like me rely on mechanics as I'm likely to waste time and money diy-ing stuff but this makes me think again
indeed…me as well…ebay is delivering my park tools as we speak.
I've taken my bike to a bikeshop very few times, one of the times they couldn't even cut the steerer straight, my mate also took his race bike to a big brand bike shop and in the service notes they said the chain was dry (the chain was waxed) and it looked as if they put some kind of mechanical grease on the chain meaning it had to be cleaned and waxed again. If you're actually into cycling and ride alot it will cost you far more money taking it to the bikeshop multiple times a year than it is to just buy the tools yourself and watch some youtube tutorials, and you don't have to worry about someone else messing with your bike because they have other ideas of what needs to be done or how it should be done. You can get all the tools including a bearing press and extractor for less than £100 so that'd pay for itself after a year.
Reginald Dunning and Kruger does bike maintenance.
Biggest issue I have with removing bearings, you NEVER re-use them so don't remove them until they are being changed.
When that is happening, it doesn't matter if you use a puller or drift them out.
As far as I'm aware, (plus over 50 years as a mechanic) you don't 'preload' deep row ball bearings but you do take the piss out of engineers who can't work on their own stuff because it's too difficult and only possible during assembly at the original factory (yet we manage to invent ways to fix the shit turned out without just buying new or sending it back)
17:28 threaded top cap? So bolt is threaded into the top cap? I've never heard of nor seen that. It should simply be a hole. The collar is normal, but threaded collar is not. I don't think that exists. I can't see a valid reason for threads there. The bolt is threaded of course as it goes into the compression plug. And yes using grease there is a good idea, of course no need do go cray, just a bit of grease to stop if from getting stuck. Only the bolt should move, thus no threads in the cap.
Why is it threaded? I can't make sense of it.
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.
@@Hambini But why is it threaded? That does not make sense to me.
@@HambiniI've never seen ITM on anything. I checked dit out only found pics of compression plug and a stem. Seems like the brand does not exist anymore.
@@mtbboy1993Providing you can generate the clamping force, the bearings don't care. I guess the ITM guy didn't care about having logos lining up.
@@mtbboy1993 ITM stands for Italmanubri. It is an Italian brand that makes handlebars, stems and seatposts. Most Italian bikes in the past had something from ITM on them.
Merry Christmas Reginald
OMG, this is your best yet. I’m in stitches here laughing my ass off . Pure gold
Merry Christmas hambini
I knew about that kind of topcap because my Cannondale has one. It seems that it's a bit tougher to set preload accurately. The manual threatens warranty will be void if another compression plug is substituted. It's known that a Cannondale warranty is worth nothing. See the videos from another U Tuber with 3 replacement frames, the last one also purchased and defective at the steer tube top bearing seat. I don't expect anything from them, so it's not even registered! With it's oversized rotors I'm on my own anyway. At least the stem bolts had been torqued to spec on the carbon steer tube. Maybe it won't kill me this year! After all, none of this has the Schwinn stamp of approval!
Wonderful reaming😂 BUT there is such a thing like corrision between steel and Aluminium. It is not real corrosion but a white powderly Connection between the two materials after years of usage without removing the seatpost. Had several years ago a seatpost stuck to a frame and it was a pain in the *ss to save both.
Happy new year,Sir🐷🍄🍾
Hanbini is such a bully.
Perhaps you could work together. Although why are your rim brake pads the wrong way round.
@@jonnysellerBecause i'm a shite mechanic
What effect might ambient temp. have in the BB diameter measurement? Enough to move beyond tolerance at that sort of accuracy?
Titanium's expansion is 0.00000714 meters per meter per degree C. So, a 50mm diameter tube heated by 20C would increase diameter by less than one hundredth of a mm. I doubt that will ever matter. Titanium has about half the expansion of steel for the same temperature rise.
@@chriswright9096 Thanks!
C02 is, in fact, not pollution. 🤷♂️
It is though...
Hi Hambini. I have a question technical questions about measuring BB30 (or similar) bores in frames. Do you prefer to use a telescopic gauge and an outside micrometer? An inside micrometer? Or you prefer to use cylindrical blocks used as no/go gauges? Additionally... how do you check the two bearing surfaces are concentric, and/or parallel?
The gauge is the best way for an overall measurement, if the hole is oval, a stick mic is better
Yea. He's a bit on the spectrum. On another note, I made a comment on a mapdec video about grease and carbon interfaces and got shot down in the replies (not by mapdec)
.. lets dive in ..
😂
Cmon guys… this is just an old fashioned Pissing contest…may i suggest a livestream pissing contest 😂. The loser gets to apologize to David Arthur and say “All hail!” to Peak Torque..
Definitely an Aldi caliper I got the same one to start with last year but surprisingly very accurate! Still bought a better one anyway when funds were better but still look at the aldi one out curiosity to see how off to the expensive one and never been off yet so really can't knock it
Peace and goodwill to all men ….well most, except those who don’t know what they are talking about ..
11:49 looks like he used the correct tool. But the tool shown here won't work, bearings shown seem to be different. It clearly worked in his video. All you need is the correct tool. Yes if it's like you show here it won't work. 🤔
well it didn't, he damaged the spacer.the end is deformed.
You hate criticism and you left out a lot of important parts, which proves you made one of the worst tutorial videos on the internet (headset video). It doesn't matter that it's your own bike and that was a few years ago. Any serious engineer should be ashamed of themselves
I don't claim it was a good video or that I am competent. I'm just saying Reginald is a clown. If he owns a bike shop he should know better
Sorry dude - no headset top cap should ever sound like that.
Well there 35 bottom bracket videos with carbon that do sound like that
Who puts lube on there top cap bolt?
What is the correct tool to use to extract bearings in this use case? I would love to know as my Spank Hex front hub has this exact configuration.
Look up “blind bearing puller”. Should do the trick.
@@reineherrera8897 which is exactly what this video shows to be the wrong tool in this case
@@iffy_too4289😂
The lack of industry standards and uniformity in the cycling industry is honestly comical.
Hambini!I think you made this guy famous😂
As far as the top cap and bolt goes, remove
and tap the cap and separate because you
do not want to tighten up with the cap bonded
with the bolt, you want the cap separated from
that motion when tightening up the bolt. Its just
full of crap/dirt/gunk from you not being bothered
about the weather with the bike. X
The sarcasm. Love it!
@@Trippenzoid your comment sounds like a much needed self-reflection, tell me I'm wrong.
That Reginald guy is a joke who tries to gain attention/subscribers by mentioning your name.
I think he does too. A disproportionate number of videos on his channel have my name in them.
Reginald goes on a bit I must admit, but he's pretty much on point.
IIRC, before his first video name dropping Hambini, he had less than 1000 subs - I became aware of his channel last year because of his post about his Cinelli Nemo that I considered getting
This Reggie is like that true crime UA-camr who constantly make videos about his obsession with Lucy Letby, even that he has attended her court cases and sentencing and now plans to attend her appeals
I think it was fine. At least the bike servicing video.
I watch both of you. I think you both have valid opinions. But that headset bearing video was a car crash. I was actually shocked that it was something you would have posted on here. I initially thought it might have been a wind up.
One note: a cheap digital vernier caliper is about as consistent and accurate as a “insert crap & or junk analogy here”
The thing is hambini is a well known personality, has a sizeable following and is at this point a 'brand.' No publicity is bad publicity and whoever Reginald is is just getting traffic by mentioning hambini.
Most people will only go there once. The guy is a complete plonker who seems to cater mostly the misty eyed fools that think road bikes peaked in the 90's and anything that isn't 11 speed 105 rim brake is over complicated and bougie. The epitome of "a little knowledge is a dangerous thing". I'm pretty sure that any half competent home mechanic knows more than he does about bikes.
ever wondered why the Park Tool 46mm reamer is only 45.94mm ?
No idea. Do you know?
When I do frame corrections, I usually go for a 45.98 on the boring machine. The tricky bit is getting both sides aligned within range. Machining the hole is easy, getting them aligned is difficult.
@@Hambini no idea either. I end up having to enlarge the hole. Still experimenting with the best method to get some kind of alignment. I have rigged up a tia from the seatpost on a frame right now. Using a frame gage to get the centreline.
@@Mapdec Imagine if yout fitted a CBear on Reginald's TI Frame!
Are there other reamer brands with a better size?
@@_Zane__ I usually use Dormer but that will be a custom size. I don't know if PF30 or BB386 was originally designed to be Hole basis or shaft basis, it's not clear.
I think Reginald is a halfords mechanic
No matter > he clearly is not a mechanic using the wrong tool to measure a round hole.
I suggest dueling banjos at dawn for the reciprocating reamings....Hambini versus Reginald, a fight to the last note or string.
Top cap sounds to send chills down the spines of those who travelled on the Titan submersible and lived to tell the tale 🥴
The guy thinks Co2 is good for the planet. He's clearly trying to build an audience by taking pot shots at you.
... and it is.
Moderation
CO2 is plant food. More is good. Even more is better. It improves crop yields. Feed the world.
He's taken a basic concept, that Carbon Dioxide is necessary for photosynthesis, and concluded that this means that climate change isn't real.
That's like saying that drinking water is necessary for life on earth, therefore flooding is harmless
If I understood you correctly, the bearing manufacturer suggested that you do their reaming for them, for our viewing pleasure! 👍
Reginald Perrin
"some of the things he does, you could end up hurting yourself doing them" - like riding gravel on 25mm tyres. Ouch.
You're being a bit unfair with the alignment. That shell has been machined after welding to rectify the heat distortion. The evidence of that is it's thicker and thinner.
I went and watched his video on how to remove a bearing. I knew before i even clicked, what hes gonna say and he sure is. Grabbed blind bearing puller, overtightened it and used puller and not a slide hammer.
I kinda agree if there is space to put that type of a bearing puller in and only slightly tighten it, but no chance. On that small size of a bearing with that small of chamfer, this puller aint grabbing nothing, untill you squeeze it. then in kinda ruins the point, since you are deforming bearing. If you were to cause damage that is definetly how.
I myself would of knocked out with a punch too, or at least partially to properly engage puller and pulled it with a slide hammer, and not that dinky clamp screw type style, that is destined to marr hub surface and bend a spoke when it slips :)
Also he is wearing nitrile gloves, well seasoned mechanic, that
Also valid point about grease. For the life of me couldn’t figure why bike “mechanics” grease sealed bearing in headtube and its inner and outer surfaces like its a motorcycle with 2 part bearing and separate cage with balls
The measurement of the bottom bracket with calipers is not accurate cause the caliper "fingers " are square so the actual dia would be slightly larger. ( I think you have mentioned this before ) .
They are actually sharp blades at least on good calipers, but its is near impossible to guarantee they are centred and perpendicular so calipers are at best good for a rough diam. To add to that, most cheap calipers under $250 or so do not have enough precision to measure a bearing bore though even if you did manage to pull a real number. 0.001" is about all you get form a basic mitutoyo with is not enough to accurately assess PF30 tolerance. If you have a $20 amazon type... 0.002" over 2 inches is dream land. It will tell you absolutely nothing.
Oh no we miss the princess blanket 😂😂😂
Is a verneir caliper accurate enough to measure interference tolerances? I wouldn't have thought so.
I liked his video on why CO2 is good.
Just goes to show any bloke can call themselves a bike mechanic. There is not governing body to confirm credentials (like engineering). Just like naturopaths call themselves Doctors - fukking joke!
Which governing body confirms engineering credentials ? I've had the dubious experience of working with a few Part21J, D.O. engineers and a CVE who were bordering on incompetent. A couple of them also held C.E. status .
@@Andy-co6pn I think the Euro Ing is a lot more rigorous than anything else. You need academic quals, then C.Eng and I think ti's 6 years more on that.
Bike mechanic: In Germany it's a trade, regulated by a body. Calling yourself that you're exposing yourself to fines. 'Engineer' however is regulated by law. You'd face criminal charges (Amtsanmaßung (for awarding it yourself), Betrug (fraud)) and civil charges (Verstoß gegen das Ingenieurgesetz), though usually "only" mid four-figure. Same goes for carrying the title but translated. You don't need any practice however, just a qualifying degree from a university.
In Canada, Engineering is a licensed profession.
@chriswright9096 How is competence proven or is it just paper qualifications ?
im not here for the sarcasm, not really here for the engineering highlights, im here for the recommended advertisements in the captured UA-cam segments to learn more about the one who calls himself a magical hamster.
I can't help but notice how the chair keeps shaking throughout the video and can only assume Hambini shakes his legs like most of us Engineers or there's a hairdresser outside the video frame.
A good quality blind puller is perfectly capable of catching the radiused edge of a bearing inside a freehub with no protrusion past the radiused edge of the preload spacer.
No mechanic would use the type of pullers you show in this video.
Correct, he’s lying to his audience.
he doesn't understand the concept of tolerance
I have luck... bike mechanic removed bearings on my old alu wheelset with that odd dentist tool...
So I would rather bring my Hypers to my dentist when needed - anyway, she is a psychopath, she says, when I come around.
Thanks, Hambini, you saved my teeth (I don't care for old wheels).
In automotive you use certain tools for certain jobs. I do my own bike work. Having a mechanical background.
Hambini, your video only proves that you are good engineer and a bad bike mechanic. Stick to your profession.
Apparently bike mechanics require more education.
dont they get some kind certification these days ?
doesnt appear to be working @@ccuellar6212
Your comments prove that your an incredible moron and a pathetic troll…..go away.
If damaging the spacer is bad, why do you have videos of you hitting one with a pin punch?
Hi Reginald! How many alt-accounts can one man have???
This is what we all love... The Drama! Especially at Christmas time.. I subscribe to you both, just so I can see the too and fro of course. Happy Christmas to you Hambini, may all your pens be working, and your hairdresser aptly glazed. Godspeed you filthy 5 year old.
Clearance Clarence 😂 it is important.
I use wax on parts I'm afraid will seize or corrode. Only grease or oil in sealed bearings. Seems like wax is more water proof and will last longer to which means better protection.
It is very common for both carbon and metal bottom bracket shells to have thicker walls on the bottom side by design.
You shouldn't have brought up the subject of co2 given all the misinformation around the politicized subject of global warming/climate change. Just to inform you on how important co2 is to the environment and all life on earth, I submit the following facts, etc for your further reading: All life on the planet dies in a mass extinction event at co2 levels of 150 ppm , plants can no longer live below that level but levels below .03% would drastically reduce plant growth. At .08% co2 plant growth doubles, at .12% plant growth triples. However, not all plants use co2 the same way, type 3 plants groups(grasses, corn, etc) have only one pathway to use co2 and requires direct sunlight but type 4 plant groups have two pathways to utilize co2 (Deciduous trees) and do not require direct sunlight and convert 2x the amount of co2 to oxygen . Type 4 plant groups start being replaced by type 3 plants at co2 levels below .04%. .... With higher co2 levels comes stronger plants as well with reduced need for water, fertilizer, and pesticides. Runoff from big agra farming practices is polluting the planet and destroying our health (nutrient content and micro-nutrient content of fruits and vegetables is 75% lower than it was 100 years ago. The mass hysteria surrounding climate change/ global warming has ignored the issues that will kill off humanity 100 x faster than climate change ever could. Historically, of course, the planet's co2 levels have been over 8x higher than they are now and apparently the planet survived quite well.
Your a special kind of stupid aren’t you? Climate science has never disputed CO2’s role in the ecology of the planet. Your arguments are as irrelevant as the dickhead who was being reamed. Go and put on your tin foil hat…..wanker…
