- เผยแพร่เมื่อ 11 พ.ค. 2020
- And in today's episode of Engineering Nerdporn we have me and my bottom bracket for my Look bike.
I've also drilled the frame and flipped the stem over.
I will be doing a video about the design and manufacturing of this bottom bracket shortly.

The bit about fucking the chicken was so good I had to do it twice. There is now a page on hambini. Com to sign up for an alert when the BB is released
Cinderella face gonna have her head knocked about em crankset teeth. I was expecting a refresh for a boys cover weeks ago. I am disappointed
The cycling press thought you’d turn a corner and seen the light but nah. 🤣
Hambini fucking a chicken that is already fucking... Savage!
I think I need a Look carbon bicycle in my life 🚴🏼♂️
So, if I want that BB for my 25 y/o 68mm BSA Ti frame shell, how much am I looking at?
hey hambini just want to let you know, your video is looped at the 8 minute mark...
Aero bike on the cheap step 1: Get access to a machine shop and learn how to design and machine custom high precision parts out of steel and aluminum.
Bike on the cheap..
Me: mixing old spareparts tiagra, 105
5yo: Throws some freakin di2 on it :P
Di2 is peanuts, it's like 20 pounds if you steal it and leave 20 buck on the counter, hehe :-D
I think he just has some Claris parts and he's used his new fangled pen to write Di2 on it. Works for me.
The most anticipated video of 2020
Now wait untill part 4, in 2021 :-)
Can confirm ‘hello Hambini fans’ is stronger than most coffees as I was about to head to bed and am now fully awake.
Oh dear, you shouldn't have clicked!
Hambini to be honest, I am glad I did click. Because the part where you happily draw like an actual 5-year-old with equipment you got from a stranger on the internet is absolutely priceless.
Niels Heldens phrasing
stronger than speed and coke combined, lol. Or eating an evil chicken alive !
@@Hambini Do you use any kind of grease or anything when installing threaded bottom brackets? The dry sand sound when installing hurts my 4 year old mindset, while thinking about dating zombie chickens
God I thought you were going crazy when you said quality and ceramic bearing in the same sentence until you put that kicker in!
Somewhere in Bristol there is a charity shop, in there is a woman called Belinda, she is identified by her big pair of bazookas.
Nice job Hambini!
Enjoyed seeing a bit about your thought process when designing the BB, and also about the trade-offs between mass-produced engineering for the Shimano BB and the tight tolerances you can achieve with your own work.
Hambini no like throwing a hot dog down a hallway! This guy is awesome in every way -- smarts, sense of humour, etc. etc.
Can't wait to see the wheel choice! Really enjoying this series of videos @Hambini as much or more than the roasts! Love seeing the machined solutions and thinking behind them.
Would love to see part 4, very interested to know if you will keep and use the look?
Just finished my aero final exam and now greeted with more aero.
Hope it went well
I am interested to see part 4. This build is like an assembly store and I like it. I hope it comes out soon. I want to see the finished build.
Another outstanding video.. I learn something every time I watch your videos. Thanks!!
Just went to bed and now I have to get up and watch this.
Thank you for a well engineered product Hambini, you are a good human!
Man, I wish I had one of your precision engineered bottom brackets, that looks smooth af.
it'slosenotloose Ive got Record and Dura Ace BBs 30-40 years old. Still practically smooth as new!
@@rollinrat4850 That's why they had to do something about it. They wanna sell these things and they can't do that if they last forever ;-) It's like with light bulbs. They are having a celebration in some US village for their light bulb that is working for >100 years. In 1932 (?) light bulb manufacturers agreed to produce sh*t they can sell over and over again...
Chris Ko Sales and marketing rule: A sucker is born every minute.
The Bible says, "A fool and his money are soon parted.
I say: YOU WILL PAY for what YOU get, one way or another!
These are all provable facts.
Hambini's excitement at discovering technology... Priceless 🤣
20:26
Hambini:“I’m so easily pleased, sorry”
...Flo wheels would like a word with you
looking forward for the next part!!!
Cheers!!!
Legend!!! Great engineering and entertainment!! Awesome video!
Love this mad engineer. More cycling and car content please.
You love him? Then marry him.
Your drag analysis is as clear as mud.
Love the previous gen Dura Ace, it looks so much nicer than the 9100. Currently running it on my summer bike.
Well done ! I love to see that 14:56 :) :) :) That's the best way of drafting ever ; pen, paper & knowledge. :)
Hambini as always - you rocks! :-) take care and stay safe!
Haha, you almost had me with the BBinfinate ' Thing of beauty' with its quality molded spacers right up to the point when you said you'll use ceramic bearings !!
nice one Hambini these videos are great
Absolutely entertaining watch while I tuck into my dinner. A digital pen pwnge Hambini for once LOL.
Thanks mate.
Hambini such a badass one very intelligent brother really like his channel
PLEASE make these threaded BBs for sale!
Luke Houghton ditto!
Yes please. And in Italian thread for my Colnago Master 👍
Treve Kneebone You don't need one! There's all sorts of great BBs that fit your bike. Check out SKF bottom brackets. Hard to find, not cheap, but Best thing going. Chris King bearings are the best in the business. None better. You can service those on the bike. Their bearings last almost indefinitely if you take care of them even semi regularly.
Ive got Campy Record and Dura Ace BBs that are 30-40 years old. I have a couple Phil Woods too. I'm not sure how old they are!
Hambini's BBs (while great) are bandaids for the suckers that bought and drank the koolaide! He's not gonna do threaded. He knows Shimano's BBs are fine! Retail on a Dura Ace outboard BB is $40. The cheapest Dura Ace part in the lineup! Team Ineos uses them I think. Cheap enough to afford 3 a year easily! But you (might) only need to replace it maybe every other year.
RollinRat I'd be interested to know if a CK bottom bracket would be comparable with a Hambini BB - given CK will align to the frame with exact presision, whereas a Hambini BB will align and create a perfect interface between bearing and crank, reducing long term wear? 🤔
Luke Houghton Chris King manufactures his components to a higher standard than just about anyone else. He's the only manufacturer who makes his own bearings, EVEN THE BALLS, as far as I'm aware of. These bearings are, by design, serviceable. You don't throw them away. I can tell you from experience, if you ride reasonably and perform even semi regular maintenance, these components, even the bearings will last virtually one's lifetime.
This is surgical grade manufacturing. Ive built surgical and medical hardware, as well as aerospace , defense, inspection hardware even carbon components for satellites and spacecraft.
I'm familiar with very high end manufacturing. I saw one of CKs hubs disassembled and I bought it on the spot. I own 7 CK hubs and 3 headsets, from 10-36 years old. They're all on the original bearings.
I haven't tried a bottom bracket yet nor have I seen a Hambini unit in person. Hambini's bearings aren't really serviceable AFAIK. Maybe someday I'll get a CK BB. At $150, that would buy me 4 or 5 Dura Ace or XTR units at my costs. That's probably enough to easily last me the rest of my life! I had a Shimano XT unit that lasted 12 years of hardcore abuse and epic rides! $25!
Dr Hambini educating and entertaining us
Would like one of those BB's!! Some nice piece of engineering :D
Engineered Perfection by Hambini Aged 5 ™️
Again very nice enigineering. In the end this LOOK/Hambini bike will be bike of the year in comparisement of price/quality/performance.
Methinks you need to do a tutorial on drilling carbon frames for Di2...
Duraace R9000 is still the best looking groupset
JogBird hard disagree. Used to love that crank. Also liked the DA that preceded it. Something about the quality of DA in addition to the style. The material. The feel. Less so the operation.
If I could find a newish crankset I’d grab one for my TT bike
I have the 9000 in di2 but i out the 9100 crankset on. The 9000 reae derailleur was and imo much nicer looking
taste is always different......🤔
@Bas Bakker ive got 7900 calipers on a backup bike and they are nice looking.
Glad you put Reynolds AR in you recommandations, I bought a set of them last month. I'll test them next days since we can "enfin" go riding out in France. I'll tell you my thoughts if you're interested.
Hambini is a sterling example of what makes Britain Great.
AGH! I always fiking forget to take my headphones off for the start lol 😂 Gorgeous bike though Hambo!
The most waited vídeo of 2020! Really surprised if you choose the Shimano wheels because you cant use a NTN or SkF bearings, and need to go with cup and cone.
This BB its an amazing peace of art!!
Saw a Disney Princess bike for sale on Gumtree, thought about buying it and sending it in for a new Hambini BB LOL.
The king of bottom brackets.. sweet as.
Oooh! That future BB video is anticipated...
Hambini: I am French
Also Hambini: calls it a "front mech"
Also Hambini (at 18:45) "une chien" instead of "une chienne" - apparently doesn't speak French!
@@frostsmoke So was King Cnut, apparently. Dyslexic, I mean.
Hello Hambini you freakin legend, I too was pretty impressed with that bottom bracket spin. Can you save me the time of watching every freakin video you have and show us your absolute best ever lowest friction longest free spinning crank spin test in all the history of time? In your words, "the lick of spins"
Ooh, are we going to see a Hambini headset 😍 though I’ve been quite satisfy with FSA headset wise.. With Di2, I don’t want to see Wiggle Prime on it.. Reynolds, Carbon Ti, even Shimano be lovely. It’s a shame this bike will only look clean and sparkling on it’s maiden voyage. I can see this replace Cevelo as the main ride. It’s going to be smashing.
If the head tube is reamed and faced first, and the top cap doesn't have gorilla preload put on it, most headset should last well. FSA kit gets a bad rep because it's generally bunged onto unpreped frames by venture capitalist lifestyle marketeering catalogue companies.
Almost got me when Hambini said he's gonna put other company's BB into that bike lol
I have a set of those Prime wheels, got them with tubes and tires for ~500 USD. nice to know that all I'll need to do for a great setup is pick up some nicer hubs and relace them when I can afford it. For now they're working fine.
FYI, I bought new deep section LightBicycle wheels last September. From the off, all my Strava segments were 5-10% faster than on my old Mavic Aksiums (helped also by the new Conti 5000s) and, 1500 miles later, they remain 'as new' with no sign of misalignment or rim wear. No regrets.
5 year old discovers the wonders of a digital pen :D
Have a look at parcours wheels! All fully wind tunnel tested and affordable 👍. Great vid and love the 🐔
To be honest Matt, I think the days of the wind tunnel are dead. At achievable speeds, a wind tunnel is not representative.
Hambini I agree but I remember them banging on about achieving better figures than zipp so you may find it interesting 👍
Wind tunnel marketing is an anti-buy now
Are BSA BBs gonna be available for purchase any time soon?
I wonder the same!
It's taking a little bit to get used to the new Hambini. Almost don't understand your "new language". Love you're back...a true Hambini Fan
Just fyi, I got a SRAM ad before your video. So sweet.
OK, should have watched to the end of the video to see the 3 second mention of "drilling holes inside the bottom bracket shell" for the DI2. I would REALLY like to know how you did that trick! Can you please cover that in a later video?
I have a KG386 frame, size 53, c2003 model, which weighs 1560g. Bottom bracket shell is solid alloy and I would imagine there's not much room inside that chainstay to pass a cable internally, although I must admit I've been wrong about a LOT of things in the past. Will enjoy watching the video of that particular fishing trip.
ROFL I lost it when you said you were going to use a bbinfinite xD
Bloody hell still Cinderella !!! When Toy Story out to be worked on
Think it's gonna be Frozen!
Let it go would you? 😉
Professional PowerPoint: proceeds to play with the pen for 5 min
flipped the stem... perfect!
fuck you just woke my whole house up with that intro
worth it still
Funny isn't it. A few years back shimano used bigger bearings then decided nah sod this smaller is better our shit isnt failing enough.
Then we had to get spacers for our bottom bracket tools, due to smaller shells.
But shimano includes an adapter with bb now?
Shimano claim this is more efficient due to less friction at the seals. I don't know if they are right.
@@carlosflanders518 well clearly not because my BB uses much bigger bearings
@@Hambini I've always been in the bigger is better camp. Shimano are claiming that the larger seals cause more friction at the outer lip, as far as I can figure out.
Yet the new, smaller ones last longer than old ones. I did on my road bike more than 15 000 km on that with smaller bearings. Just don't tighten the left arm frickin tight or power-wash them and they will last...
Aero Wheel Suggestion: Far Sports.
They can make the wheels with either Novatec, or Carbon -Ti hubs. Prices are competitive and their customer service is superb. I requested specific track Novatec Hubs and 32 spokes. The final product is well finished and recommended.
Hambini, love the videos. Thanks for all the valuable content. Im currious what frame set, if any, you would recommend for someone to build up? Looking for a race bike which could last 10+ years.
You R the MAN!!! Belinda has 2 🐝 the bike’s name!!! (So you can legally ride her around town😋🤪🤩) No seriously cool video! I’ve a Rebellato aluminum/cf boutique frame (Castel Franco, Italy 🇮🇹) w/Campangolo mechanical groupset and Miche rims w/Durano tires...I named her ‘Sophia’ after Sophia Loren😛 Call yours Belinda of Paris 🇫🇷 and then auction it off for charity!!!
I visited the light bicycle factory in Xiamen a couple years back and was honestly very impressed with the QC I saw out there. (Mech Des Engineer here) If you fancy ordering a pair I would be interested to hear what you thought of them!
You had me with that bbinfinite and i was like whyyy would he use that??? Then you dropped the bomb and i was too stupid to believe you'd actually use it 😂
7:40 A bit of loop/ repeat going on.
CnE reinforcing his point on how shit the OEM one was
HAMBINI........ trapped in his own Ground Hog Day ??
It's a glitch in the carbon matrix🐈
Sir! You are king. I tip my hat and glass of scotch at ya.
It's so stiff... it's so smooth... It's Ero Bike! :-)
It's no accident. It's Hambini aged 5! :-D
I doubt Belinda is concerned with areo gains but having her horizontal would be a good thing 👍
I just can't understand why would a man with the brains and the humour of Mr Hambini would have any hate in the very level headed. cycling community. My man! wheres part 3 of this vid! i've almost seen all your videos after going on a BB rabbit hole. Now i hate the people who own a chunk of the company that built my bike and for sure had input in the design of said bike FML
You might want to considers Newmen's new Fade hubs, similar to Carbon-ti but not as noisy, no preload needed, almost as light.
Hambini does DI2! Whooot! I was hoping you were going to go that route. Do you have holes internal to the bottom bracket shell in the bike so you can fish the DI2 B-junction and the various wires down into there? Are you going with the internal battery inside the seat post? If you are, make sure you get the SM-BTR2 so it supports the wireless connectivity to the EW-WU111 wireless module. Assuming you are interested in wireless data connectivity to your head unit (Garmin or whatever)
My bottom bracket is as smooth or even smoother than that big thanks to you👍
I've watched this twice now and you got me twice with that BB Infinite joke.......maybe us antipodeans are thick...
Great vids Mr Hambini :) just one thing leaves me perplexed - latest wind tunnel tests with a dummy rider (like Tour magazine) shows that frame has a big impact on the overall aerodynamics and wheels surprisingly low impact..so I just scratch my head now..
That smooth spinning crank gave me an enginerdgasm.
how do you pronounce that
@@Hambini sound it out, bro.
@@Hambini engi nerd gasm
happy days.
I’d also say that there’s too much preload on the headset bearings.... 🤔.
but indeed an interesting project! 🤙
Your handwriting says your medical talent is being wasted.
It makes two of us... Rgr
That’s legible. Your doctors must be horrible
if you want fast hubs, you could go for the industry nine hydra hubs, I think they got the most engagement points at the moment, BUT they are ar from cheap :D
Helloooo Hambini fans
Shú Hello Hambini fans all bar one. A lesser known cycling weekly lady. ( girl if under 50 )
I got a sense of deja vu in the first 9 minutes
About bloody time 😃 let me put the kettle on
Oooh that BB.. what a smooth criminal! I’m ashamed it took me till the ceramic part for my spidey sense to kick in, injction molded plastic bah... I was wondering if it’ll be a shimano Ultegra or a hambini special and I was not disappointed, thing of beauty.
a quality bike frame with the right bb
Having just upgraded to discs, I'm selling my Prime RR50 wheels if you're interested in getting those for cheap. I'm Bristol based as well
If he isn't, I am! also based in Bristol
Wasn't joking, still interested, find me on Facebook me if you are 👍
@@Lloydbmxandmusic3 Sorry I didn't see the notification from your reply! I have just got round to listing the wheels here - facebook.com/marketplace/item/668158277240075
How about the zipp 808s from your timemachine? I presume you can interchange them quite quickly?
Good video 👍 the number of issues with BB's and the need for expensive alternatives seems to be an endorsement of the Campag system? With UT cranks the original bearings sit in the same place, as intended, with Campag supplying either a press fit cup or screw in.
woah... deja vu
*Hambini drills holes on a carbon frame.
*What a fucking legend 🙌
2am... ; Hambini: HELLOOOOO!
"this is the sound of f#*ckness, my friend!" - made my day!
Hi Hambini. You mentioned handlebars at the end. Sorry if you have previously answered this, but I was interested on your take of handlebar width and if the standard 42cm is too wide or, alternatively, a good sweetspot between aero gains and control on descents? I just ordered 40cm bars. I had 44cm aero bars, just because my bike is XL and they assume therefore that I have wide shoulders. I also was wondering what you thought about the idea that a highly positioned handlebar, relative to the ground, enables most riders to get flatter and more aero, or is slamming your stem the better way to go? Otherwise thanks for the content and honesty :)
Bottom bracket made out of the elusive superlight aluminum in a 50 quid frame, i bet somewhere in Japan some bitter tears are being shed right about now.
My current (standard shimano threaded) bb is nowhere near that free spinning. If this is due to misalignment, would fitting this Hambini BB resolve the issue by forcing the holes into alignment when it's tightened up? Or would it not be possible to fit unless the frame is perfect in the first place?
Imagine trying to get up the Col du Tourmalet on a recumbent. Then imagine going down it. Hunt wheels are ok btw.
Hey Hambini do you sell this particular bottom bracket for shimano hollowtech with 68mm threaded? My Road bikes BB is starting to get old and I have been waiting to get a new one.
I fitted a new Shimano threaded BB recently and noticed the diameter of the threaded cups was less than the one it replaced. It looks to me that you could make the diameter what ever you want because it is outside the frame and does not foul anything. But, there are splines cut in so a tool can be used to tighten it. If the diameter increases you need another tool. Does yours use the same diameter as the previous Shimano BB so that the old tool can be used or do you have your own tool?
