Give PT a thumbsup for the editing because the video setup we had was utterly abysmal! and he has done a veyr good job
Waiting for someone to correct the whole sentence lol
@@Eng586 i was pissed
@@Hambini it's understandable.
I will update the rev. block. "Hambini halo tolerance +/- 30 blinks /min"
*HAMBINI Linguini*
The lack of swearing is directly correlated to the light fitting above Hambini that resembles a halo.
I can't believe two such legends managed to get together for 22 minutes of no-bullshit-just-pure-truth. What a show. Keep up the good work. Hope to see more of this. Definitely a thumbsup for me.
Can we get a Patreon going to get PT a table so he doesn't have to bend over to pick up his pint every 20 seconds? Or maybe he's just flexing his flexibility.
i think he needs a high chair and table...🤣
They mentioned 3d printing but didn't get to it. If I had a big enough printer I would print a 3' tall Hambini with his hand up shaped just right for a pint glass.
@@AndrewWalter future episodes
Yes!
Hambini, I so much admire you more than your self-imposed 5 year old caricature. Thanks for sharing your expertise. 👏👏👏
That Giant bike hanging on the background is a prime example of a supplier turned competitor. Jusk ask Schwinn.
Yep, how much stuff does Giant still produce with other brand names on it?
After James Huang got his Masters in materials science engineering, he went pretty much straight into cycling media. Previously he worked as a bike shop mechanic for 14 years, starting in high school. His specialty was mountain bike forks and became known in his region as the one to go to. His father was an engineer.
He makes his own mountain bike fork too didn't he?
I agree, he asks manufacturers the difficult questions then lets their piss weak answers to speak for themselves.
@@ohshitnotanotherknob In my opinion, he still drinks the Kool-Aid, but less so that most cyclist "journalists".
Watching Hambini and PT together in one video is like watching Pacino and de Niro together in Heat.
18:26 James Huang has a undergraduate degree in microbiology and graduated in materials science engineering at University of Michigan (source: alliedcycleworks interview)
Nice job
Props to Hambini for just hearing that in how he talked😅
I started reading Cycling Tips because of James' review articles. When I first got really into cycling 6-7 years ago I was searching for reviews as much as possible before purchasing certain gear. It started to look like everyone just took the marketing material and changed a word or two (like the kid writing a school paper using nothing but Wikipedia and a thesaurus). But James' reviews (especially the long-term reviews) had so much more to them. He's not immune from including some marketing cliches, but overall you get the sense that he's not just sucking up to brands and will actually point out weaknesses/potential headaches for prospective consumers.
Excellent…the two most knowledgeable cycling bloggers providing unpolluted info…10/10.
I really loved this, please keep it up. So refreshing to hear a couple of engineers being non biased and not influenced by marketing
What tools do you recommend - GCN & Cycling Weekly 😂😂😂😂
I wouldn't recommend them though.
HELLO PEAK TORQUE FANS!
Did anyone spot my Halo. I'm angelic
@@Hambini All 5 year olds are angelic. Nothing new... Rgr
This is such a great video. Thanks to both Hambini and PT for teaming up, bouncing off one another and presenting some really interesting material. You two could easily make a podcast and receive a solid audience imo
Cheers. Lots more to come
Pleasssse demystify this wide tire and tire pressure debate. I can understand that a 25 might be faster then a 18mm but Jan heine and co make it Sound That a 45 mm tire should be used in the pro peleton.
Also, the difference between wider and narrower tires is not that much. The difference between, say a 28c on a 19mm rim, vs the same tire on a 25mm internal is minimal. Hardly measurable.
In terms of comfort, there definitely is a major difference.
For racing however, I would choose a faster tire in the first place, not a wider slow tire. You see so many tires that are claimed to be fast, that are not. Pirelli PZero, Bontrager R3, Vittoria Corsa (not Speed), Maxxis, Veloflex Corsa etc are just several watts slower than the best road tires. A Continental GP5000 or Specialized Turbo Cotton will outperform any of the aforementioned tires, regardless of the width. For time trialing, a Vittoria Corsa Speed and especially Veloflex Record will outperform any tire by a country mile.
However, that is bad for cycling outlets to say, because that would mean, that most products are shite, and could never advertise there. So they just say, any tire is faster on a wider rim or in a wider nominal width (which might be true from a Crr POV, not so much when looking at weight and especially aero), so everyone can publish their ads there.
Put a skinny tire on the front with a narrow rim for aero and then a fatter tire on the back for comfort. The thinner rim may be a bit twitchy in a crosswind, but we're racing bikes not ballet dancing. Sometimes you've just gotta handle the twitch.
pretty sure they will hit this.
There is no debate.
To be fair though, I do go faster on my 44s René Herse with their Endurance casing than I ever did on my 32s Continental GP 4 Seasons.
This colaboration is priceless!! Well done Hambini and Peak Torque! Learning so much from you two.
Thank you!!! Your inputs and viewpoints helped me create my dream build: Felt B2, cf tri-spoke tubulars w/veloflex gummies, Campangolo’s Veloce mechanical group-set w/titanium gold chain!!! Very slick bike!!! Thanks!!!!!!
Fantastic information here guys, one of the best videos I’ve seen in ages. Honest , Informative and on topic
Putting you two together, is simply a winning formula!
Btw no mentioning of likes or subs. I've grown so tired of hearing that all the time. Liked it right away.
Great stuff thx
Don't forget to like and subscribe ☺️
@@PeakTorque 🤣
Excellent work guys, can't wait for episode 2!
these guys are the best . My first recommendation to any new cyclist is your s and hambinies channel . so that they dont go out there spending money on shit they dont need .
fuckin a right!!!
Great to see you guys collaborating... 👍
I love the mutual respect from two highly educated and opinionated experts. Best 20 minutes I've spent today. thanks a lot.much appreciated
We need more of this! Enjoying the video over a cup of coffee. Greetings from California! 🤗
Enjoying this while at work in SoCal, hey neighbor!
@@basedgodstrugglin As another from SoCal, I can safely expect that since you are working there are likely to be at least 3 other employees nearby that aren't working !!! That's the Cali work ethic.
@@richards4422 alternatively… I had a rare down moment and worked my ass off until I got off lol
@@basedgodstrugglin When you got off, I hope you took a minute to wake the other three up before you left for home.
@@richards4422 oh no none of us worked today. The store fell apart. Poor us…
Love this collaboration guys. You two are two of the best cycling personalities on the internet with your no-nonsense, no bullshit presentations. I am not an engineer but have been calling out bike industry bullshit for years. A lot of people look at me like some sort of biking heretic who doesn't know what he's about. Keep doing all that you do and I hope to see more collaborations like this. Cheers 👍
Excellent. More please. I'm particularly pleased you talked (albeit briefly) about how the most well known cycling channels have to peddle corporate hype as a major source of income and so fatally damage their credibility. Even the smaller channels fall prey to this with sponsored, loaned and freebie products that they don't always declare very clearly. Keep it real please guys - we're relying on you!
Totally agree. 👏👏👏 (btw, it’s peddle ...meaning, try to sell)
@@hisdadjames4876 Oops! Correction made!
@@Robutube1 Good for you, my friend - responsive instead of defensive. 👏👏👏
Brillant! let this be the start of a great series 👍👍👍😃✌️
Great video. More collaborations please from both of you. My 2 favourite bike-related youtubers.
this needs to be shared around. Pure GOLD
You guys are doing great work, keep these coming 🙏🔥🍻
It's like Huawei known as cheap phone and in a few years took basically the US government to shut them down. Great video I hope you do more.
Good stuff! Looking forward to more.
l love the honesty from actual engineers about bike tech AND not afraid to tell you truth about all hype in marketing and the REAL value of these bike snob parts actual performance gains !!
This is awesome!
- I remember Hambini once mentioned that a U-shaped rim profile gives you slightly better handling in crosswinds, but that the aerodynamic loss is far greater than a similar V-shaped rim. What's the difference in power loss of a U-shaped rim profile vs a V-shaped profile for, say, a 50mm rim (ceteris paribus)?
- How deep would you estimate a U-shaped rim needs to be to have the same power loss as a shallower V-shaped rim?
- With all that, would you go for a U-shaped or a V-shaped profile?
- How big is the benefit of aero shaped tubes? Or are the wheels way more important?
- How do full carbon rims with carbon brake tracks of the new Big Three (Winspace, Farsports & Light Bicylce) compare to wheels with aluminum brake tracks? And how do they stack up against rim brakes?
- Any thoughts on Lapierre road bikes (Aircode & Xelius)?
Thanks guys and hello from Boulder City Nevada!!
Enjoyed this, very good work.
Wow!! Waiting for this! 🥰
This is awesome. Please keep making these.
This brings me back to my mech engineering degree, nice work guys
This is a great gathering of two well educated bike enthusiast's. Great one.
And the good thing this is lightingspeed *Ach nein* what do I say it is warpspeed ahead and way more interesting compared to the tictoc level vids the vasectomy guy from down under does...
Please do more!
Big fan of both of you!
My new favorite podcast
Love this lads, more collaboration please
the most important video series for cycling imho
Gcn, gmbn don't do reviews, so they mostly do event coverage and technical vids, and answer questions.
I love the green Hambini Halo! We know you have a devilish heart.
I need to bring popcorn 🍿. Can’t wait how it will unravel with this oil refinery thing
Great Collab session gents! With your combined expertise, and China Cycling, time you guys got your own frame, develop Sensah as your own groupo , add some LB wheels and I bet you guys could do something cool.
That's a double negative
Great show guys, very interesting listening to objective thoughts instead of marketing hype.
99.9% of so called cycling journalists are just advertisers for the big name brands.
People will continue to buy the name brands as GCN and co will push them.
Interesting with all the HYPE (no pun intended) about the Winspace Hyper wheels, none of these people have reviewed them.
nice session, waiting for more
A weird nitpick: FEM is a method for solving partial differential equations (also the fluid equations if you want).
Good to hear you guys talk about James Huang. I personally like the guy.
I need to go and grap popcorn. this is going to be fun. Refinery specialist!
Peak Torque your video from back in January 2021 about titanium material was interesting and welcomed. I like and own titanium for the proper reason, it's durability. As far as ride quality goes I think bicycles ride like bicycles and like you mentioned compliance comes from the wheels. I'm real glad that guys like you and Hambini are trying to educate the idiots and silence the bullshit marketeers. However, the effect this might have if it catches on to the masses is the manufacturers will quit showing the new products on UA-cam and just use magazine publications where they can get their hype out without feedback. They are never going to stop using smoke and mirror engineering language to try to sell to the idiots. So glad you two are creating this channel and looking forward to the content. I know you guys have a limited budget but any information on the new Classified Gear Hub System I would like to hear about.
My advice back when I was coaching triathlon was always ‘get the bike that fits’
Great stuff guys!
EFFZEE... hambini put his best shirt on; and he definitely nailed it 1000%. 👌
Thumbs up for James Huang
Good call on the ribble bar tape - all for modular grips a la the new Pro bars but still have a question on how long they last - says the man with minimal strips of skate grip tape on my TT rig. And yes 7075 - it’s what Nicolai use for their new (and my 15year old gearbox downhill mtb) frames -solid
Great content, keep doing it!
Tools: Always calibrate your Park tension meter to the spoke you're measuring.
I subscribed after watching this particular video.
Never knew that frosted tips and five year olds would go so well together
Looks like you have a little halo above your impeccably maintained flocks Mr Hambini!!!
I'd love to see Peak and Hambini both get an ideal aero bike 3D model/sketch drawn up and see how they compare for ideas (but then someone would only copy it). I also love this as an extension of letting the public know don't be fooled by marketing hype.
Things change over time........I remember when Giant bikes were looked down on for being made in Taiwan,I had a Giant CFM2 back in the 90's ,it was a good bike.Lots of bikes in 80's,90's were china/taiwan made and rebranded for europe/U.S brands.
Personally I buy Campagnolo wheels because they are nearly half of the price of Zipp and Enve, they have smoother hubs, and are robust and aero at the same time. Their clincher wheels have been fantastic, because I can run tubeless tires on them as well.
Good on you Hambini🤣🤣🤣 I really thought you are an aerodynamics engineer. But wasn’t expecting oil refinery worker
I've got Alu handlebars, rond at the mount though flat at the mount. Best of both
Can you elaborate
@@gxexrxmxaxnx sure, they have the comfortable flat surface in the inner part, though are nice round at the drops. So it is aero/comfy whilst still versatile
Witty, Funny, two best minds in the bike industry.....
Because they're not in the bike industry.
On the Ribble handlebar: they could have gone the route of the new Pro-handlebar with customizable rubber inserts on the places where it counts.
If one goes for a naked Carbon handlebar like that, maybe adding some of that thick transparant crocodile tap could could work: my downtube is protected with that, and the tape is there without needing to replace it it ever since I applied it.
Thanks for the answer!
Great guess, I’m Thai!
Saving this for later. I hope it won’t vanish too fast.
I unashamedly use tyre levers on a particular wheelset and tyre that I just can't get in or off by hand.
Is Hambini auditioning, fot the lead roll, in a remake of, The Saint?
Lovely show. I do think the handlebar rotation is overstated; if you're doing something strange to the handlebar tilt I wonder if you are compensating for issues with other fit dimensions of the bike. Or maybe I'm just fortunate to be built for the handlebars being setup properly.
Anyway, the guys at Ribble deserve credit for offering bars in different and rather narrow widths as well. I saw a significant increase in speed going to narrower bars and it's really tragicomical to see bike manufacturers putting 42cm integrated "aero" handlebars on medium sized bikes.
For me, and the trend with the younger pros it seems is to have the drops completely horizontal. I spend a lot of time in the drops and this is a comfy position for the wrists. A lot of aero bars are just plainly badly designed! For instance look at the Giant Propels integrated bars. The drops are pointing steeply down witht he aero section at 0 deg AoA. The sworks aerofly is good, enve good, but there are some real bad ones out there.
😂 hambini, the master of surprises!
I think what you both are doing is absolutely brilliant, your like the bike industry Police, exposing the bike industry fraudsters.
Sorry for the late one....just thought of it. When Jonathan Shubert broke the 100 mile in under 3 hours record it was on a 10 year old Giant Trinity with a few home made mods, so do you think bicycle aerodynamics has reached its pinnacle within the rules? Thank you
First of all, the big brains repping James Huang is a massive boost right there. I also love JOM at the Gravel Cyclist...though he too toes the line some.
Also ordering up a Waltly Ti bike because the craftsmanship is on par with a Moots or whatever boutique Ti outfit out there (save for double butting Ti tubes but I'm certain that isn't far behind).
Here's a question: that 9 tooth cog (or 10 tooth in the case of Sram AXS) on the Ekar grouppo. Thoughts on the loss of efficiency? Further, Shimano opted to forgo it on their 12sp road stuff due to loss on efficiency...but they mess with 10t cogs on their MTB drivetrains. So are they just trying to avoid having to engineer some smooth shifting on a 10t road cog or is there something there?
that website is a proper reaming of hambini🤣 my god i was not expecting to see an oil refinery job.
Great stuff. Agree on wind tunnel b**s()t. Yes, to narrower bars, I'm on 38m would like 36. Re. Chinese competition - as long as the big brands keep increasing prices, the more they leave the door open to the Chinese to try and sell direct.
If we're talking about 'most people' just take 3 spacers out from under the stem & put them on top. About the same aero gain as 6K worth of frame.
Most of those people would then not be able to do any meaningful watts. But I'd say a huge number of people running slammed or close to would be faster with spacers ... they don't really understand the implications of the change in position, geometry, and why their watts are so miserable when they're pretty fit.
@@pmcmpc huge generalisation
This was very enjoyable. Have you considered a podcast or even a Patreon? I'd definitely tune in.
Will we ever see Dura Ace or SRAM Red going Mechanical ever again?
Bike industry's worst nightmare duo!
They wanna make money they gotta do road shows like twatson and harris 😎
Love Hambini's halo 😇
opening so awkward I love it
Nice FC cologne polo shirt, Hambini
effzeh
Hambini is a saint. There’s a halo !
Damn grindr dates getting Intresting
Best 1-2 punch! 👊
Great video. Bit of a shock seeing no powerpoint from Hambini and really amazed that the colourful language that he is known for was nowhere to be seen. Must have been something to do with that halo he wore for most of the video.
Refinery engineer at prax. Just wow… hambini
Ayy good to see you sweethearts letting it rip. It would be great if yall could increase the competent content. Winspace for the W.
the better (mechanically) a material is, the harder it is to work with, machine and so on
I haven't able to find a clear answer for this and I know you gentleman would be the right people to ask; will heavier pedals cost more watts compared to extra weight on another non moving part on a bike such as the frame?
Thank you.
Aw man, I was wracking my brain for questions and then I got one today... too late.
Can you talk about how overpriced these bikes are today and how customers are getting ripped off
lol i think everyone already knows that
@@mikes1984 Durianrider is the only one that talks about how much these bikes really cost.
What is your take on Seka Exceed frames? Seems that it is a package that is not just from an engineering point of view a good bike but also looks apart.
Hambini so down to earth. “Round handle bars so you can mount things” i was thinking that before he said it. How am i going to mount my gopro to an aero handle bar.
There's no aerodynamical benefit in having aero handle bar if you are going to mount stuff on it, especially a bricky gopro.
@@82vitt most of us dont fast enough for an aero bar to make a difference
@@retroonhisbikes I know it's a gimmic. I use the 3T Aeronova simply because I prefer to be grabbing a flat handle when my hands are on the tops, than a round one. It does have a round section in the middle that extends
past the stem clamp far enough to accomodate a round clamp. There are aftermarket solutions for flat handlebars too.
@@82vitt thanks i ll have a look
