Many companies have issues with the press fit bottom brackets. Their manufacturing tolerances are too wide. This is why many companies have switched to t47 or back to bsa and the like. Its easier to get a quality fit by installing a piece of metal and threading it. Many bottom brackets can go 7,000 miles. Most of my bikes never got an upgrade to the bottom bracket or the cranks. Some went flying off many jumps with only a tire for suspension. Were talking old square taper stuff that everyone turns their nose up to today.

I would say you have it backwards on the machining side of things. Judging by the distribution of high and low spots on the side with the flange, considering you have more than one per revolution, this is the side that has been fixed in the lathe.

Edit: maybe the video was too short for some of your Hambinites. Some more detail - This BB is by no means a feat of engineering, it's just a tube with 4 toleranced and concentric diameters. However, it is very well made. It will be orders of magnitude better than a carbon BB shell in terms of diameter control and concentricity. Concentricity is the key to bearing life, low drag, and being kind to the spindle. Such as the standards we're subjected to in this sport, we appear to be crowing over something normal and just well made. Do i need one? No. Fortunately my bikes' BB shells are well controlled and I've never had any problems with the plastic 2 piece stock options (either Shimano or gxp). One is still original from 2017! If you 'need' this BB to correct a bad frame, consider your frame choice or warranty options. Negatives. Not many but if your frame is *really* bad and is too tight on it's shell, pushing this in is quite intrusive. You need to be aware of the hoop stress you're imparting on the frame's fibres. You don't want it to ream it's way in. Disclosure: Mr Hambini did not know i was making this video. Joe (China Cycling) sent me it for some basic QC.
It's kind of expensive but if its only made one by one at different specs it will cost alot. As a machinist I can say the problems comes when you do the backside, the first operation is machine the outside an inner diameters. After that it must be flipped to do the last bearing surface after straighting it up with a indicator. And also soft backs is needed not to get marks.
I think you and Hambini are a perfect team. Your reserve and his.....mmmmm..."Eloquence" seems a match made in heaven. it would be a interesting to see some collaborations.
@Nick Maclachlan I agree with everything you say after your first sentence: "It's neither really." This is where I disagree: if bicycle prices were reasonable for the quality of engineering encountered, I would - like you - discount the greed motive. With them being where they are - a "good" bike costing as much as a motorbike, and a top-of-the-line one costing as much as a small car, I really have an issue with dismissing greed as a cause of some of the issues.
High quality engineering such as in the defence industry, aerospace or F1 areas, is a costly business. Machine setup requires time consuming care by skilled operators, the post machining QC checks (not statistical probability but individual examination) is time consuming and costly, and reject rates can be high.
It's really easy to make a handful of very expensive things. A lot harder to make lots of relatively expensive things... I don't think people really appreciate this about mass manufacture.
9:05 I remember in one of his video (about open cycle triying to sue him), that Hambini said 0.05mm was what he would expect from bicycle manufacturers in term of concentricity tolerance
@@PeakTorque People care about quality until it gets in the way of features or rock bottom price. When most brands have their frames produced under contract by a third party, it's no surprise.
If it's 10 times the cost of an OEM-spec BB, you've got the choice of running the Hambini into the ground or having regularly refreshed bearings. A PF cup is typically plastic, so you've got something slightly compressible between the cartridge bearing and the not-perfectly-round shell in the frame. This could mean the deviations in the shell don't distort the bearing too much, whereas with the alu body of the Hambini, you've got a fight between shell, BB body and bearing and one of them needs to give way. Yes, a compressible bearing carrier means you might get some interesting torque across each bearing that translates into additional axial load, but is that going to wear the OEM BB more or less than 10 times faster than Hambini's BB?

FYI for the "threaded is better" guys - it might not creak, but it also might not turn. I have an aluminium frame with a Shimano Dura Ace 7700 BB installed, and it turns beautifully smoothly right until I tighten the lockring. With the lockring tight, it turns like it has lapping compound in it instead of grease. I worked in a bike shop in the '70s, and this wasn't unusual at all. Campagnolo made tools to fix these things one would not expect on a Colnago, Masi, Coppi, or (name your favorite old brand here) that cost you $1000 when minimum wage in the US was $1.25 an hour. Facing bottom brackets, chasing the threads, and squaring the head tube ends were well known to be essential to getting everything to work properly. Later in life I worked on road racing motorcycles and was perpetually amazed at the junk the factories sent out the door - brake mounts dragging on rotors, telescopic forks with axles too short causing severe binding on compression, suspension pivots engineered too small wearing out their bushings in less than a season...I wish it weren't so, but it is. And that's not even mentioning all the crap we had to fix with the engines themselves...a guy could spend 200 hours easily prepping a bike for a completely stock class without doing any cheats, just fixing the factory's garbage compliance with tolerances.
At the beginning of the pandemic I bought an older Moots with BB30. Had it not come with a King already installed, I would have purchased a Hambini just to get ahead of the shortcomings of BB30. This was an excellent review and thanks for doing it.
Would love to see you do similar testing on hubshells (are DT swiss, for example, better than others... both exotic/expensive like WI, CarbonTi, i9 and standard/cheap like Bitex, Novatec)
From what I can gather after watching hours and hours of hambini the actual savings is probably single to low double digit watts at any sort of achievable speed, but its mostly about not getting creeking noises and to get the BB bearings to last for the designed lifetime.
No it disny! No such thing as precision, thats just a subjective term. Engineering 101 here as you get down to a certain level of tolerance you just look closer to see the imperfections and notice 2 things can never be made the exact same.. "trust me i know what im doing !" LoL 🤣 (only i will get that joke lol)
Any chance you can make a similar video testing an off the shelf shimano equivalent? Forgive me if you have already done this, I had a quick look but couldn't find it.
Hambini could definitely market the "Hambini Orange". I would totally buy a BB in orange from him just so I could scream at people who ask me about it.
The tolerances bearings are made to are incredibly tight. Its not likely that there will be any issues there. Now a test of the crank spindle- that could be interesting.
My thoughts exactly. From my metalworking experience it is much easier to achieve close, repeatable tolerances on a CNC. Manual Lathes leave a lot of space for human error (slide spindle backlash, tool setup, dirty toolpost during tool changes, bad depth of cur during roughing or finishing etc.). You can also tell that this HAS in fact been manufactured on a CNC Lathe. If you look at the chamfers you can tell that they were cut with a small cutting edge. On a manual lathe you would use a angled lathe tool with one relatively long, continuous edge unless you want to re-angle your compound which requires an annoying amount of time to do precisely.
I have two of the master,s bottom bracket and I must say nothing because I don’t have to the bottom bracket does all the talking,so you have the money PLEASE send it on this product as it will make you do this 😀 great job Hambini keep up the first class work.
Well I didn’t see that conclusion coming from the way the video started! I’ve ordered 2 of these for 2 of my bikes and will be ordering more in due course. Squeaky bike no longer squeaking! Oh and you’ve reminded me I’ve not left a review either, will add mine to the list of 5 stars
So. The plumber did good, at a cost. Sounds like the best I could hope for, with Zappa singing 'Flakes' somewhere in the back of my mind.

@@PeakTorque Just letting Zappa set the expectations about plumbers as a contrast against your review. It's all looking surprisingly good against that background. Any background, really.
I have 3000 miles on the one I put into my Canyon. Hambini did a review of a Canyon frame and it did do well. I bought Hambini bracket because the creaking on the OEM bracket was driving nuts.
I think the accuracy of the outer surface is unimportant as you indicated. The main benefit of this structure is having both bearings mounted into one very rigid, very concentric and straight piece of aluminium instead of them being in cups separately pressed into a not-so-accurate and also quite flexible bore molded into a carbon fiber frame. With this arrangement the bearings are rigidly held in near perfect alignment so the bad tolerances of the bottom bracket bore in the frame don't matter as long as the sleeve is held reliably. On earlier carbon frames they used a machined aluminium sleeve bonded to the bb bore into which the bearings are either pressed or mounted in threaded cups which achieves the same good alignment as the Hambini construction and eliminates the sloppy tolerances of carbon fiber from affecting bearing alignment. I have two carbon frames, both the old style with a bonded aluminium bb sleeve, one with threaded cups, one with pressed in bearings. Both have been ridden for thousands of kilometers on the same bearings, no creaking or other problems. I think the fundamental mistake is mounting the bearing cups directly into a molded carbon fiber bore, it's simply not accurate and rigid enough to act as a bearing mounting surface. Of course the modern way is cheaper and slightly lighter but in my opinion it's a poor design. What this product does is correct a critical flaw in the frame design by essentially converting it back into the older, better, though more expensive and slightly heavier, system.
Just stumbled onto the great Hambini and I am about to watch this review. I have an S-Works Tarmac SL-4, which I built at the start of 2014. I moved my SRM (Shimano) to the new frame so I needed a non-standard BB or use the sleeves that came with the frameset. I went with the Praxis Works BB and this thing has been solid. It's still going strong.
The ZTTO company went a step further with the Threaded BB 386, BB30 with double O rings to make sure any vibrations are not amplified by the carbon BB area. They actually did a very good job "copying the gasket design :o)" at making not only installation super easy as both sides press in together by threading them slowly but the simpler design of 2 pieces means pressing it in leaves less damage and less forces applied to the BB carbon area cup faces versus the one piece Hambini or Wheels Manufacturing ones.
You have to take your cable guides out on a tcr or the center sleeve crushes them, also the cable guide won't go in properly, however mine still works fine albeit the inner cables rattle in frame now in small ring
I guess what I'd really like to know is how well within tolerance it stays once it's fitted to a frame (imperfect or otherwise). I own one of the PF30 to BB30 version and I think it's a great bit of kit and with the SKF MTRX bearings I'm hoping that the setup will last a few Scottish winters on the cross bike.
@@AquaPrince27 that's a pretty terrible lifespan so it better be better than that. I got over 40k miles on a BBinfinite before repacking and it was still pretty good at that point
@@J88HNT in some of his videos he explained the reason: since the bb86 shell is 41mm wide, and the DUB spindle is 29mm, only 12mm are left for the metal sleeve and the bearing itself, which means that both of them will be undersized and prone to failure. Such cranks are better suited for BB shells with larger bores, like PF30, BB386evo, T47, etc. that can take wider bearings and will have more room for a thicker and stiffer BB sleeve.
If you didn't watch this to hear what you wanted to, then it's a fair take on the part itself. I'm happy you didn't endorse it's application, since the frame dimensions dictate the solution. If you can't correct the bore in the frame, then any bottom bracket will work as poorly as the next.
I would have loved to see you do the same test with the token ninja BB. That way we can have a clear comparison before spending 5 times the amount on a Hambini BB.
Your point at the end, "whether you need one is up to you"; how do you know if you need one? If you're racing, whether its bike racing or triathlon and you have a list of different potential products on which to spend your cash, where does one of these BB's fit on that list? Obviously its going to depend on how crap your current BB is but as a rule of thumb, how does one of these BB's compare to other potential additions to your steed.
really helpful info for us bike noobs trying to make good consumer choices! Honestly so fucking grateful. I like to do my research before spending big on tools. been thinking a trek carbon sport, but im probs getting a look bike now. Amazing reviews !
Thanks for the excellent review. Do you think this device can be used to check the alignment and roundness of the BB in newly-manufactured carbon frames? Regards, Gerrard.
And to think that bb was removed from a frame already and the tolerance is that good , wondering if you got one that was not used how perfect it could be , hambini is the shit man ,🤔😜
Great video. How would this compare with a Dura Ace BB in tolerances, bearings etc? Or is it just a "better design" for frames with imperfect tolerances? I gather pro teams favour Hambini BBs so if you have money & watts...
I don't know how it would compare to a standard Shimano BB in terms of tolerances - good question. I suspect that BB tolerances on Shimano parts (from Tiagra/Alivio up) will be worse than this, but still way better than the frame. A better BB isn't going to do anything (other than possibly have slightly longer lasting bearings) if the frame tolerances are bad.
Hambini, I love your stuff man, keep it going! Cheers ... This video I’ve just watched is a little pointless though as it concentrates on the precision of machining on the externals, which as stated are pressed into a carbon frame where the tolerances will be shite. The person making this video should’ve heated up the BB and dropped the bearings out and then used the precision measuring equipment to not only check the internal diameters but also the concentricity and also the machined relationship between the two bearings. At the end of the day the performance of the BB is all down to how these two bearings are aligned with each other.and that the interference fit of the bearings with the BB is correct. Sorry to be a bore but I’ve been an aerospace engineer all my career ...
The basic idea of this BB is to solve the problem of the bores in the frame being misaligned. The purpose of the continuous shell is to persuade the frame toward alignment. So in that sense the exterior is the unique design feature. I would bet that the interior tolerances and bearing selection are notably better than say a Shimano unit, but that it doesn't really matter since the Shimano units are more than good enough. And in both cases the crank spindle interfaces with a delrin surface rather than the inner bearing surface. And finally, I would bet my bottom dollar that no bearing interface meets anything like its original tolerance after a couple of hundred km under a strong rider. If it doesn't creak and the bearings last their service life--mission accomplished.
Small handmade parts have got to be better than mass production CNC stuff. Good to see that hambinis done it the way it should be done. Question is we should all be doing this instead of buy stuff.

If Hambinis BB isn’t the shiz, would those of other manufacturers be specks on the anus of humanity by comparison?
Would need a log scale
Absolutely. Still waiting for bronze bushings to be the latest and greatest setup. The consumer is gullible. Hambini cuts through marketing hype!
The Science of Hambini.
5 yr old punk can run a lathe, that's for sure mate.
I think you and Hambini are a perfect team. Your reserve and his.....mmmmm..."Eloquence" seems a match made in heaven. it would be a interesting to see some collaborations.
I'd give a score of 10 in the over-engineered scale - a bit like buying a Ferrari for the school run.
thats the point

"the frame you're pushing it into will be a bag of shite". One thing at a time I think.
For an endless supply of bottom brackets just paper mache a loo role and then use a black wax crayon to waterproof it. Thank me later
Instructions unclear, I'm now out of toilet paper
This is the real reason people were mass buying toilet paper

I love it. My anonymous source - Joe from China Cycling.
Hambini performance plumbing! He makes a great product like the major manufacturers could have done but were too lazy.
I suspect it's more about greed than laziness
@Nick Maclachlan I agree with everything you say after your first sentence:
"It's neither really."
This is where I disagree: if bicycle prices were reasonable for the quality of engineering encountered, I would - like you - discount the greed motive. With them being where they are - a "good" bike costing as much as a motorbike, and a top-of-the-line one costing as much as a small car, I really have an issue with dismissing greed as a cause of some of the issues.
High quality engineering such as in the defence industry, aerospace or F1 areas, is a costly business. Machine setup requires time consuming care by skilled operators, the post machining QC checks (not statistical probability but individual examination) is time consuming and costly, and reject rates can be high.
It's really easy to make a handful of very expensive things. A lot harder to make lots of relatively expensive things... I don't think people really appreciate this about mass manufacture.
9:05 I remember in one of his video (about open cycle triying to sue him), that Hambini said 0.05mm was what he would expect from bicycle manufacturers in term of concentricity tolerance
interesting, maybe do a cooperation? Scare the big brands into better quality?
People don't care about actual quality, they just want a bunch of Specialized engineers spewing marketing copy.
@@drunken_moose I'm not sure they *want* that. It's just become the norm.
@@PeakTorque People care about quality until it gets in the way of features or rock bottom price. When most brands have their frames produced under contract by a third party, it's no surprise.
If it's 10 times the cost of an OEM-spec BB, you've got the choice of running the Hambini into the ground or having regularly refreshed bearings.
A PF cup is typically plastic, so you've got something slightly compressible between the cartridge bearing and the not-perfectly-round shell in the frame. This could mean the deviations in the shell don't distort the bearing too much, whereas with the alu body of the Hambini, you've got a fight between shell, BB body and bearing and one of them needs to give way. Yes, a compressible bearing carrier means you might get some interesting torque across each bearing that translates into additional axial load, but is that going to wear the OEM BB more or less than 10 times faster than Hambini's BB?
@@EmyrDerfel a properly machined bottom bracket would not cost 10x to mass produce. That's just bullshit
Great review. I have a T47 from Hambini. It is great...gettitng a PF30 too....great products and this was a great review.
Paid £175 for mine.
Flawless for the last twelve months.
I stick 1800w through bracket at some point though sprint. Never been a problem with this bracket.

FYI for the "threaded is better" guys - it might not creak, but it also might not turn. I have an aluminium frame with a Shimano Dura Ace 7700 BB installed, and it turns beautifully smoothly right until I tighten the lockring. With the lockring tight, it turns like it has lapping compound in it instead of grease. I worked in a bike shop in the '70s, and this wasn't unusual at all. Campagnolo made tools to fix these things one would not expect on a Colnago, Masi, Coppi, or (name your favorite old brand here) that cost you $1000 when minimum wage in the US was $1.25 an hour. Facing bottom brackets, chasing the threads, and squaring the head tube ends were well known to be essential to getting everything to work properly. Later in life I worked on road racing motorcycles and was perpetually amazed at the junk the factories sent out the door - brake mounts dragging on rotors, telescopic forks with axles too short causing severe binding on compression, suspension pivots engineered too small wearing out their bushings in less than a season...I wish it weren't so, but it is. And that's not even mentioning all the crap we had to fix with the engines themselves...a guy could spend 200 hours easily prepping a bike for a completely stock class without doing any cheats, just fixing the factory's garbage compliance with tolerances.
Always nice to see someone pass peer review so well
Yeah boy, just what I need after my ride
At the beginning of the pandemic I bought an older Moots with BB30. Had it not come with a King already installed, I would have purchased a Hambini just to get ahead of the shortcomings of BB30. This was an excellent review and thanks for doing it.
As you said at the end of the video, it's horses for courses. I normally have to find "economic solutions" rather than spending to victory
Would love to see you do similar testing on hubshells (are DT swiss, for example, better than others... both exotic/expensive like WI, CarbonTi, i9 and standard/cheap like Bitex, Novatec)
Nice to see you've backed up Hambini's work! 👍
Belinda must be proud.
Exactly how many more percents faster, compliant, aero, stiffer, feels good and lighter is it than other BBs?
Zero
From what I can gather after watching hours and hours of hambini the actual savings is probably single to low double digit watts at any sort of achievable speed, but its mostly about not getting creeking noises and to get the BB bearings to last for the designed lifetime.
Hambini is precision down to the micron which equals perfection
No it disny! No such thing as precision, thats just a subjective term. Engineering 101 here as you get down to a certain level of tolerance you just look closer to see the imperfections and notice 2 things can never be made the exact same.. "trust me i know what im doing !" LoL 🤣 (only i will get that joke lol)
Love dry English wit X Engineer humour ...best combo in the game
You can’t hide your admiration for the bb, yet at times can’t stop bowing to the Big Bike Brands cartel.
Any chance you can make a similar video testing an off the shelf shimano equivalent?
Forgive me if you have already done this, I had a quick look but couldn't find it.
Hambini could definitely market the "Hambini Orange". I would totally buy a BB in orange from him just so I could scream at people who ask me about it.
Part of me wonders about doing a roll out test on the interior surface of the bearing that would contact the crank spindle ...
The tolerances bearings are made to are incredibly tight. Its not likely that there will be any issues there. Now a test of the crank spindle- that could be interesting.
Need to mount this BB on a spindle, support the spindle ends on V-blocks then check runout on outer diameters.
Another one proudly owning a Hambini BB. Not just because it works so good, but because I'm a tolerant frame.
Refreshing to see that hambini knows what he's talking about! Especially as he gives out so much flak... Good video
Rightfully so for dishout out flak for substandard products being sold at eye watering levels. Cervelo anybody?
Not hard to get tight tolerance on a CNC , it's probably held in a collet in stead of a chuck so you have more even pressure on the bar .
My thoughts exactly. From my metalworking experience it is much easier to achieve close, repeatable tolerances on a CNC. Manual Lathes leave a lot of space for human error (slide spindle backlash, tool setup, dirty toolpost during tool changes, bad depth of cur during roughing or finishing etc.). You can also tell that this HAS in fact been manufactured on a CNC Lathe. If you look at the chamfers you can tell that they were cut with a small cutting edge. On a manual lathe you would use a angled lathe tool with one relatively long, continuous edge unless you want to re-angle your compound which requires an annoying amount of time to do precisely.
Before he started measuring I was sure he had found a faulty part and would start calling Hambini a C-U-Next-Tuesday.
I have two of the master,s bottom bracket and I must say nothing because I don’t have to the bottom bracket does all the talking,so you have the money PLEASE send it on this product as it will make you do this 😀 great job Hambini keep up the first class work.
Thanks for this excellent video!!! My faith in Hambini was not misplaced...
Well I didn’t see that conclusion coming from the way the video started!
I’ve ordered 2 of these for 2 of my bikes and will be ordering more in due course. Squeaky bike no longer squeaking! Oh and you’ve reminded me I’ve not left a review either, will add mine to the list of 5 stars
And thank you Hambini, I’m a new fan And the Pen Is working !!
So. The plumber did good, at a cost. Sounds like the best I could hope for, with Zappa singing 'Flakes' somewhere in the back of my mind.
Well, my toilet went crazy
yesterday afternoon
The plumber, he said:
Never flush a tampoon.
This great information
cost me half a weeks pay,
and the toilet blew up
later on the next day.
We're millions and millions,
and we're comin' to get ya.
We're protected by unions,
so don't let it upset ya.
Keep up the good work, both of ya! :D
Wow. No one can top this comment. Utterly confused by entertained.
@@PeakTorque Just letting Zappa set the expectations about plumbers as a contrast against your review. It's all looking surprisingly good against that background. Any background, really.
I have 3000 miles on the one I put into my Canyon. Hambini did a review of a Canyon frame and it did do well. I bought Hambini bracket because the creaking on the OEM bracket was driving nuts.
I think the accuracy of the outer surface is unimportant as you indicated. The main benefit of this structure is having both bearings mounted into one very rigid, very concentric and straight piece of aluminium instead of them being in cups separately pressed into a not-so-accurate and also quite flexible bore molded into a carbon fiber frame. With this arrangement the bearings are rigidly held in near perfect alignment so the bad tolerances of the bottom bracket bore in the frame don't matter as long as the sleeve is held reliably.
On earlier carbon frames they used a machined aluminium sleeve bonded to the bb bore into which the bearings are either pressed or mounted in threaded cups which achieves the same good alignment as the Hambini construction and eliminates the sloppy tolerances of carbon fiber from affecting bearing alignment. I have two carbon frames, both the old style with a bonded aluminium bb sleeve, one with threaded cups, one with pressed in bearings. Both have been ridden for thousands of kilometers on the same bearings, no creaking or other problems. I think the fundamental mistake is mounting the bearing cups directly into a molded carbon fiber bore, it's simply not accurate and rigid enough to act as a bearing mounting surface. Of course the modern way is cheaper and slightly lighter but in my opinion it's a poor design. What this product does is correct a critical flaw in the frame design by essentially converting it back into the older, better, though more expensive and slightly heavier, system.
a 1 piece press-fit bottom bracket. you need an exact length if you buy one.
Just stumbled onto the great Hambini and I am about to watch this review. I have an S-Works Tarmac SL-4, which I built at the start of 2014. I moved my SRM (Shimano) to the new frame so I needed a non-standard BB or use the sleeves that came with the frameset.
I went with the Praxis Works BB and this thing has been solid. It's still going strong.
Im using a Praxxis BB in 2014 sl4 too. Like you say, solid. Never creaked.
That was a good spit-roasting. What's next?
Chinese frames! Send Peak Torque a Winspace frame to check tolerances. Send one to Luescher too.
The ZTTO company went a step further with the Threaded BB 386, BB30 with double O rings to make sure any vibrations are not amplified by the carbon BB area. They actually did a very good job "copying the gasket design :o)" at making not only installation super easy as both sides press in together by threading them slowly but the simpler design of 2 pieces means pressing it in leaves less damage and less forces applied to the BB carbon area cup faces versus the one piece Hambini or Wheels Manufacturing ones.
Rest assured he makes superb parts as you have found out. 👍
I hate how youtube algorithm is justifying my purchase.
You have to take your cable guides out on a tcr or the center sleeve crushes them, also the cable guide won't go in properly, however mine still works fine albeit the inner cables rattle in frame now in small ring
I guess what I'd really like to know is how well within tolerance it stays once it's fitted to a frame (imperfect or otherwise). I own one of the PF30 to BB30 version and I think it's a great bit of kit and with the SKF MTRX bearings I'm hoping that the setup will last a few Scottish winters on the cross bike.
I’d guess it’s gonna last at least 5 years on a bike being ridden 100 miles a month
@@AquaPrince27 that's a pretty terrible lifespan so it better be better than that. I got over 40k miles on a BBinfinite before repacking and it was still pretty good at that point
Why not include BB Infinite to have some comparison?
Second this
BBInfinite is a cheaper alternative, and they have more stock. I also want to know how good their stuff is.
I’m going to order a Bbinfinite bb because Hambini doesn’t make a BB86 for SRAM DUB.
@@J88HNT in some of his videos he explained the reason: since the bb86 shell is 41mm wide, and the DUB spindle is 29mm, only 12mm are left for the metal sleeve and the bearing itself, which means that both of them will be undersized and prone to failure. Such cranks are better suited for BB shells with larger bores, like PF30, BB386evo, T47, etc. that can take wider bearings and will have more room for a thicker and stiffer BB sleeve.
@@c4p3fi3rr we know the reason why, but there are always having a "BUT". LOL
Even have the mic holder. Nice
If you didn't watch this to hear what you wanted to, then it's a fair take on the part itself. I'm happy you didn't endorse it's application, since the frame dimensions dictate the solution. If you can't correct the bore in the frame, then any bottom bracket will work as poorly as the next.
Far less swearing than a Hambini video, I only counted 1 "shite".
Great BB though, I may have to get one.
Love the plumbing truck
I would have loved to see you do the same test with the token ninja BB. That way we can have a clear comparison before spending 5 times the amount on a Hambini BB.
Your point at the end, "whether you need one is up to you"; how do you know if you need one? If you're racing, whether its bike racing or triathlon and you have a list of different potential products on which to spend your cash, where does one of these BB's fit on that list? Obviously its going to depend on how crap your current BB is but as a rule of thumb, how does one of these BB's compare to other potential additions to your steed.
Hambini BB is the one I would buy. Exelent engineering! Nothing comes close.
really helpful info for us bike noobs trying to make good consumer choices! Honestly so fucking grateful. I like to do my research before spending big on tools. been thinking a trek carbon sport, but im probs getting a look bike now. Amazing reviews !
Thanks for the excellent review. Do you think this device can be used to check the alignment and roundness of the BB in newly-manufactured carbon frames? Regards, Gerrard.
G's running 3T robot made frames now; curious to see if Italian bots make a better hole than Chinese children...
And to think that bb was removed from a frame already and the tolerance is that good , wondering if you got one that was not used how perfect it could be , hambini is the shit man ,🤔😜
no score marks, looks as new.
However, hard to score metal with carbon fibre anyway.
So, it could have deformed from install and removal.
Let's go HAMBINI!!!! 👌👍🤘💯
In Hambini we trust
Great video. How would this compare with a Dura Ace BB in tolerances, bearings etc? Or is it just a "better design" for frames with imperfect tolerances? I gather pro teams favour Hambini BBs so if you have money & watts...
I don't know how it would compare to a standard Shimano BB in terms of tolerances - good question. I suspect that BB tolerances on Shimano parts (from Tiagra/Alivio up) will be worse than this, but still way better than the frame. A better BB isn't going to do anything (other than possibly have slightly longer lasting bearings) if the frame tolerances are bad.
Hambini, I love your stuff man, keep it going! Cheers ...
This video I’ve just watched is a little pointless though as it concentrates on the precision of machining on the externals, which as stated are pressed into a carbon frame where the tolerances will be shite. The person making this video should’ve heated up the BB and dropped the bearings out and then used the precision measuring equipment to not only check the internal diameters but also the concentricity and also the machined relationship between the two bearings. At the end of the day the performance of the BB is all down to how these two bearings are aligned with each other.and that the interference fit of the bearings with the BB is correct.
Sorry to be a bore but I’ve been an aerospace engineer all my career ...
Not boring at all
100%- no info on the concentricity of the bearings themselves, just the OD? Seems like marketing wonk wrapped up in engineering talk.
Spot on
The basic idea of this BB is to solve the problem of the bores in the frame being misaligned. The purpose of the continuous shell is to persuade the frame toward alignment. So in that sense the exterior is the unique design feature.
I would bet that the interior tolerances and bearing selection are notably better than say a Shimano unit, but that it doesn't really matter since the Shimano units are more than good enough. And in both cases the crank spindle interfaces with a delrin surface rather than the inner bearing surface.
And finally, I would bet my bottom dollar that no bearing interface meets anything like its original tolerance after a couple of hundred km under a strong rider. If it doesn't creak and the bearings last their service life--mission accomplished.
You should do the same test on the BBinfinite ones. Like same model one for comparison it would be interesting to see
You could clamp the free end into a sled to reduce the runout.
click bait title. booo. i was expecting a genuine roasting when reading the title
Ha you fell for it, hambini bb is the best
Maybe. But the BB shell play a big role too. Isnt that what @hambini is famous for? To fix issue with the shell.
More BB than I need for even my top end bike - but choice is great!
Small handmade parts have got to be better than mass production CNC stuff. Good to see that hambinis done it the way it should be done. Question is we should all be doing this instead of buy stuff.
So the only “negative” is that it’s TOO good! The lick 👅
Well, there's the price!
Good on Hambibi! (Age 5. Yeah, I watch him.) I can make one at home but not everyone has a machine shop in their garage.
I think this BB has already been instaled on the China Cycling bike.
thank goodness -I was hoping that this engineering hero did not fall from grace like Lance! BB infinite now needs to send in one of their units!
Lance didn’t fall nice try
Top review. Not bad engineering for a 5-year old.....
