Hambini Bottom Brackets are amongst the lowest friction bottom brackets in the world. They are used by recreational cyclists, road racers, triathletes and time trialists from around the globe. They are of proven design and are manufactured to Aerospace tolerances using Aerospace materials by an Aerospace Engineer.

These units are of a one piece construction which makes them inherently resistant to creak, they will maintain perfect bearing alignment and function under loads in excess of 4000W.

All Hambini bottom brackets can be installed and removed with a conventional bearing press, they use a controlled method of installation using the recommended fitting adaptors, they require no hammers or specialized tooling for removal. Additionally, the wearing component – the bearings – can be removed and serviced in situ. Essentially the bottom bracket has been designed to be fully rebuildable

Spin Test

Spin tests are not good measures of friction as the bearings are unloaded but this video highlights the benefit of good bearing alignment on friction and bearing life. This particular bottom bracket had completed 10,000km.

Comparative Friction

The graphs below show how Hambini bottom brackets perform in comparison to the bottom brackets of other manufacturers

The test conditions model real world cycling and more importantly mimics realistic frame tolerances. All of these tests have been conducted with an eccentricity of 0.1mm which is generally the maximum permitted in frame specifications – the reality is tolerances have been known to be much worse than this.

Misalignment is more critical to friction than the type of bearing ball material, a slight misalignment can easily outweigh the difference between a top of the range NTN bearing and a mediocre ebay no name bearing. The results show that bottom brackets which have an element of structural linkage between the drive and non-drive sides (one piece/threaded etc) perform much better than those which are multi piece.

Average Power Consumption - Hambini, CeramicSpeed, Kogel, Praxis

The high torque and low RPM of pedalling causes high Hertzian contact stressing on bearing surfaces which cause friction levels to change over time. Those bottom brackets which have used ceramic bearings, start off with fairly low levels of friction but over time their friction increases dramatically. The super hard ceramic balls grind a track into the comparatively soft bearing races causing friction to increase. This would be analogous to trying to drive a locomotive train on a road, the wheels would cut grooves into the road surface due to the huge difference in surface hardness.

A Hambini BB is a one piece bottom bracket. It actively contributes to the stiffness of the bike’s pedalling platform. Threaded and multi piece bottom brackets have an element of play in their design so they do not contribute anywhere near a comparative level of stiffness. Reviewers of Hambini BB’s often comment on their feeling of improved stiffness, this is due to them being one piece and undergoing a proprietary heat treatment process. This makes them stronger and stiffer. This is a difference the end user cannot see – but they can feel.

Frequently Asked Questions

I have rounded up some of the most frequently asked questions that I get asked and put them in the list below

Q. Why are Hambini Bottom Brackets more expensive than everybody else?</strong >

A. Hambini Bottom Brackets are made in the UK where costs are considerably higher than the far east. Additionally as a private individual, I do not have the economies of scale that contract manufacturing companies are able to obtain.

Q. What is the difference between a Hambini Bottom Bracket and a mass market bottom bracket?</strong >

A. From a technical perspective, mass market bottom brackets are made to poorer tolerances and are therefore more likely to creak or result in poor bearing life. They are also designed to look aesthetically pleasing but compromise on areas which you cannot see (such as the fits, bearings and heat treatement). Hambini Bottom brackets are completely machined as opposed to moulded (Shimano/SRAM/Plastic). The Hambini Bottom Bracket tolerances are typically 10x tighter than Shimano/SRAM/Rotor/RaceFace/Token. Mass market bottom brackets often use poor quality bearings from the far east to maximise their margin. As an example, the bearings on Hambini Bottom Brackets (which are typically NTN) cost more than an entire bottom bracket from RaceFace/Token/SRAM.

Q. Why don’t you use Ceramic Bearings?

A. I have found ceramic bearings to have poor performance in bicycle applications. The ceramic bearings are not 100% ceramic, they are hybrid. A Hybrid bearing consists of ceramic balls sandwiched between a steel innner and outer race. The ceramic balls have a tendency to cut a groove into the steel and this results in poorer performance after only a few 100km. The majority of friction (>80%) in a bearing comes from the seal, grease and cage type. The ceramic balls make up a small fraction of the friction and have the negative effect of rapid bearing degradation. These are the main reasons I do not supply bottom brackets with ceramic bearings

Q. What is the difference between the Racing editions and the standard units?</strong >

A. The Racing Bottom brackets are made with superior materials, they are stiffer and slightly lighter. Racing bottom brackets are equipped wih low friction bearings. Racing bottom brackets have approximately 20 percent less friction than Classic units. The total friction is very small and would be difficult to notice when riding but nonetheless there is a measurable difference

Q. How long will the bearings last?

A. I cannot place a life on the bearings as life is largely dictated by the conditions they are subjected to. Having high loadings will increase their rate of wear as will riding in wet conditions. The bearings in all Hambini Bottom brackets are branded and meet minimum ISO standards so they are the best that are commercially available. Typical usage will be somewhere in the region of 2000km to 10,000km. As an example, those who watch my youtube channel will know my fastidious maintenance schedule which consists of weekly jet washing – I change the bearings twice a year, ie 8000km between changes. Due to the low speeds involved keeping them clean is more important than keeping them greased.

43 reviews for BB30 to Shimano Racing Edition (Black) Bottom Bracket

  1. Thomas

    So well constructed, just so perfect

  2. Kyle Steiner

    It’s difficult for me to describe how good this is. I didn’t get it for any creaking per se, I bought it to interface my Dura ace 9100 to a BB30 frame. Fitting is easy and straightforward. I used the recommended loctite products. When you are riding at full gas the feeling of stiffness is massively different. There is no lag in the pedal stroke and each one takes you further. The only negative I would say is the weight. It’s 125g versus 110g for a set of BB30 bearings and adaptors. So there is a 15g penalty. Customer Service and support are excellent. I’ve never bought from a one man operation before and had my reservations. I’m not sure if everyone is like Hambini but he is a credit to the cycling world.

  3. Barry Clark

    Installed the BB without issue, the problem I had was the crank would not go in. After a swift email exchange, I was told to put my crank in a freezer for 3 hours. I was skeptical but it slid right in. When he goes on about his manufacturing tolerances on his videos, he’s not joking. This Bottom bracket has changed my bike from a creaking POS to a joy to ride. Excellent customer service.

  4. Jamsterzz

    I had to wait 3 weeks to get one of these as they kept selling out! But worth the wait. Came in non descript padded box. I watched the video on my phone to install it and that was it. Faultless. It looks like every other bottom bracket out there but when you spin this one, you can feel the difference. High quality item, Made in UK. what more do you want

  5. Graham Watliss

    I have two of these now, both have been perfect. Bearings are super smooth and the first one has done 10,000 miles with not even a hint of creak. The quality of the finished product is exceptional. Things that let it down: lack of instruction book although the videos are good, box is recycled.

  6. Czechmate

    It’s the real deal. Pure. Unadulterated. When did I realize this? When I saw Hambini in one of his videos trying to explain something cycling-related and finding no other object “just lying around” in his workshop to illustrate his explanation than a jet turbine stator vane. I’ve been a long time user and abuser of bearings from a well known Danish company. Coated, uncoated, bottom brackets, wheel bearings, pulley wheels… I’ve had ‘em all. Hambini’s stuff? Out of the box, somewhere between a standard and a coated danish bearing. After being worn in… as smooth and as free as a full ceramic. Better than coated from Denmark. Take my word for it. The bottom bracket itself is exquisite. Where “n” equals the number of bikes you own that accept a Hambini bottom bracket, you proceed by ordering “n+1” Hambini bottom brackets. Just to be able to keep one aside, on the mantlepiece, to play with and to adore. Yes, it comes in a plain brown box. Yes, there are no colorful user manuals and fancy installation guides. But it comes with all that is required to install it quickly and easily by following his videos. You don’t even need a jet turbine stator vane. And the result? My Allez Sprint power transfer chassis (BB junction, chainstays, dropouts) feels rock solid, even under the hardest out of seat efforts. I almost regret writing this review. Out of fear that it, along with all the other reviews, will create a snowball effect and swamp Hambini with such demand that he’ll be unable to deliver and force him to close shop. Because this is only his hobby, after all. He’s a full blown aerospace engineer when he takes off his bottom bracket superman outfit. I’m so scared of this eventuality that I’m seriously considering buying up a few of his bottom brackets in various sizes “just in case” I find myself one day with a new bike or frame and no more Hambini online. So do me a favor. After reading my review, order n+1 bottom brackets. I’ll even let you write a review, like I’m doing now. But don’t talk to anyone out loud about this place. It’s the cycling world’s best kept secret. Trust me.

  7. TruckerDave

    Stunning Build, Fast service

  8. Mike Jansen

    The bottom bracket does everythign I could ask of it. It fits well, has never let me down, doesn’t creak and spins forever. You won’t find a more knowledgeable and helpful guy in the world of BBs than Hambini. Kudos.

  9. Olister97

    Customer service in a different league. The video guide for installation makes this easy peasy. Bottom Bracket is excellent polished finish. my cranks spin forever

  10. Curtis Stevens

    the bottom bracket is superb. installation was straightforward following the video. A marked difference when pedaling. no creaking and no clicking. fast delivery also

  11. Nori

    I’ve only made 100km on with this BB but it spins well and no creaking. I had good experience throughout the purchase. Hambini’s customer support is second-to-none.

  12. KB

    I can’t thank Hambini enough. His support pre and post sales have been excellent. The bottom bracket was delivered quickly and fitted easily. I have since done 2000 miles of trouble free riding. I can really feel the difference in the pedalling platform.

  13. Gaydon

    I was moving from a 30mm Rotor crankset to Shimano and instead of having lots of adaptors I wanted a direct fit. The Wheels MFG adaptors and conversion BB’s I had tried made the bottom bracket feel like mush. Not so with this thing. Super rigid, no flex. Really feel the difference going up hill. Only bad aspect is 90% of this unit is hidden inside the bike as it’s lovely to look at. Workmanship is excellent. I would recommend this to anybody.

  14. XIDU

    Bottom bracket feels well made and spins well in the bike. It is expensive but it is better than everything else I have tried by a margin. Technical support from Hambini is AWESOME.

  15. JamieK

    Hambini’s technical support is excellent, answers to questions are easily dealt with and promptly. I ordered the bottom bracket on Saturday, It arrived on wednesday, fitted it thursday and raced it on Saturday. One word – UNREAL. Performance of this BB is amazing, it really stiffens the bottom bracket area up and it feels like you are pedalling hard on every pedal stroke. First class.

  16. smashndash

    I bought this for my 2017 Allez Sprint (which is BB30, yes, despite Spz calling it OSBB). I had a praxis thread-together BB that went from brand new to gritty in a few months. Had the shop install this, so I don’t know if it was tough to install but they had no complaints. I immediately noticed a difference on the bike. It felt like the pedals were “jumping” more when out of the saddle. I only have maybe a thousand or so miles on this so far, but it’s showed no signs of slowing. We’ll see what happens after the rainy season next year. I can 100% believe that these bearings will last longer than the average junk. Save yourself the headache of thread-together BBs or (god forbid) direct-fit bearings and get this. Or at least the classic version if you’re on a budget. It truly boggles the mind to think that people are still screwing around with nylon cups. I may not have the choice to get threads on my next bike, but I will definitely only buy something that can use a Hambini BB.

  17. MDu8

    I had to wait months to get hold of this, as it was forever out of stock. A number of forum people recommended this bottom bracket to me. I was contemplating selling my bike before getting it. A remarkable piece of engineering, pick it up and spin it. You won’t believe how smooth it rotates. The dust seals are a work of art. I was dubious before I bought this as I had tried solutions from all of the “major” players and numerous bike shops. They were all Sh*t. This was easy to install, stops the creak and makes the bike mega stiff. It’s like a different machine. There is a slight weight penalty, it’s about 30g heavier than the bottom bracket it replaced but I’d sacrifice it all day. Additionally, there is no technical support phone number, just an e-mail but don’t be put off. He’ll email you back rapidly and the quality of his reply will convince your decision.

  18. Ypuh

    Add a 6th star for e-mail support and service. This guy is cool.

  19. Wissam Kasmi

    I have a BMC with a bb30 bottom bracket with “ceramic” bearing I was really happy with my bike, until the creaking begin, I have tried several methods to stop the creaking, but nothing worked for a long time, I think there was a problem with alignment and tolerance in the bottom bracket shell. I have searched for a permanent solution and when I so the YouTube video of Hambini I was a little bit skeptical , after one year of use in traing and racing. This is the best solutionI have found and believe me I have looked, I train really hard and I don’t want to lose any watts on poor alignment and creaking bottom bracket, this bottom bracket is a precision made piece of art and I am lucky I have found it. The support is fast and the delivery too. The support is done directly by the man designing and making the bottom bracket and this kind of service is priceless. You can by a lot of other solutions and non will have the precision and the customisation this man is offering. I am building a new bike with PF86 bottom bracket and I am ordering a new Hambini PF86 bottom bracket. This bottom bracket are so well done that it should be a standard.

  20. Jascon48

    Creaky cannondale – no suprise there. Fitted this and it’s like a completely different bike. Super stiff, no creaks, you can really get the power down in a sprint.

  21. James in Billings MT

    I’ve had no end of problems with my C’dale, creaking, poor bearing life.. yada yada yada. I bought this on a whim before I was going to sell the bike and boom. All problems gone. Runs super smooth, took 5 days to get to the US. As others have said. Customer service is exceptional. Even if this costed double, I would buy it. The local bike shop wanted to know where I got mine from as it’s one of the few c’dales that doesn’t creak

  22. Jason

    The product is beautiful. You won’t find a better looking bottom bracket out there. It spins so cleanly it is like buttery smooth. Fitting was easy, it was a bit bit irking hearing the noises but it went in without any issues. Riding on the bike is great, you can really get the gas down on climbs and in sprints and not even worry about creak. It stiffens the bottom bracket area up no end Customer service is at another level. I think you would be hard pushed to find someone so knowledgeable and prompt with answers. I am a subscriber to the hambini channel on youtube, it’s a very raw channel with honest videos. This product is the epitome of that channel in metal. Negatives, understandably for a small business, you don’t get snazzy packaging and it doesn’t come with an instruction manual. Who looks at them anyway? World class is an understatement.

  23. Mad Dave

    No issues, simply brilliant.

  24. Colin Rackham

    Really really well made. I can tell that this was designed and made by someone who cared. The attention to detail is really something else. I really like the fact it’s fully serviceable so I can swap the bearings at my leisure. Customer service from here is top notch. Delivery was bang on 5 days quoted. Very professional throughout. On a side note, the youtube channel is excellent as well.

  25. Jdragon

    Had tried many different bottom bracket options before. THIS PRODUCT WORKS!!! Functions the way it suppose to. Clean precise product ! Was installed on a OSBB Specialized and functions GREAT!! Thinking of getting for my Cannondale Super Six. “AWESOME!!”

  26. Alois95

    Apart from the exorbitant price. I can’t fault. Fitting and functioning both first class

  27. Ron

    Perfect for my upgrade. So quiet now, no creaks at all. Paired with Ultegra groupset, pedaling is stiff and crisp. No creaks even when i’m off the saddle on hill climbs. Amazing product. My only cons is that I live on the other side of the pond, so shipping cost is a bummer.

  28. D Hawkins

    I purchased this on the recommendation of a fellow club rider. No issues during fitment, installed the cranks and away I went. You can instantly feel the difference, the bike felt like Jelly before this.

  29. HDJ Kirstens

    Can’t fault the engineering. It is as good as everyone else has said. It is expensive but for the hassle free factor of installation and running, I’d take it all day long. My Giant bike feels like someone has put steroids in the BB. No flex and instant power.

  30. AshleyFox

    Does what it states, easy to fit. Would buy another one in a flash.

  31. Jimmy Snead

    As an engineer I like quality products and this is definitely one of them. In true engineering fashion, all of 3 seconds has been given to the aesthetic appeal of the packaging. It’s functional and got here undamaged. I fitted this on a BB30 bike. You can tell when you hold this that this is a quality product. It is extremely well designed and well thought out. It is expensive but you really do get what you pay for. A word on Hambini. His customer service is excellent. Comparing him to his competitors is like night and day. No pressure sales, questions answered promptly with drawings and technical explanations. First class. Great Youtube channel as well.

  32. Mizzle

    Looks great, rides great. I wish I could have gotten one sooner. If Hambini made a bike, I would buy it.

  33. Harry Beian

    Looks better in the flesh than it the photos. When I first got it I couldn’t stop touching it. It is sooooo well made. Props to Hambini, his customer service is awesome. Always very polite and quick. Installation was straightforward (BB30 to Shimano). I could instantly feel the difference, silence was golden and stiffness where it was a bit jelly like before. In riding, the BB has been trouble free over 200 miles. Shame he doesn’t do MTB otherwise I would have bought one for that as well. If I had one criticism it’s the packaging and the execution of the end product. You are literally buying a brown box with a bottom bracket, there is no paper manual and no retail packaging.

  34. Tony Miles

    I’d never heard of Hambini before and his name got batted around weightweenies and I watched his youtube videos. I contacted him with my problem. I got a swift reply and bought a Shimano BB for my BB30 bike. It came quickly after a week to the US. I took this down to my LBS to have it fitted. The mechanic said he’d never seen one before and I showed him the Youtube fitting video. He fitted it said he wouldn’t warranty the install and off I went. The bike felt COMPLETELY different. No slop and now ‘ing creak. I took a 20 mile ride detour in complete silence. I’ve had it one for a few weeks with 500 miles on now and felt compelled to write this review. It’s perfect. I was always prejudicial about artisan bike builders and always thought that the big boys could do the engineering well. I was wrong. Hats off to Hambini. Excellent product and service.

  35. John

    I have only good things to say about Hambini and his bottom brackets. I had a few questions before purchasing- he was very responsive, with concise, sensible answers. I bought the black edition BB30 to Shimano Racing Edition for a 2020 S-Works Tarmac Disc- he machined it in his workshop same day and a week later it was delivered to me in Australia. Followed the video instructions and pressed it into the frame with ease. To be honest, the hardest part was finding a local vendor for Loctite 641! With the Hambini BB installed, the bottom bracket is extremely stiff and completely creak free. Plus the black finish looks amazing with a Dura Ace crankset.

    Five stars. Fully recommend!

  36. Kevin Cornish

    “No Flex Given” – installed the Hambini BB30 to Shimano Racing Edition (black) bottom bracket in a 2017 specialized SL5 and it has breathed new life into the frame. it is rock solid, buttery smooth and no unwanted noises. Plus great after sales support from Hambini.

  37. Mr. C. (verified owner)

    Really quick delivery and the product is clearly excellent quality.

  38. Erik T. (verified owner)

    This experience has been a pleasure. My bottoms bracket is still being installed on the bike, but as for the quality, fit and machining, I can say it fits and looks the bees knees (if it is a piece of garbage and deserves to be a speck of shite on the Anus of humanity, I will update this review). As for the ordering/delivery experience it really has been great. Hambini doesn’t make you search for the answers as to where it is or anything like that, but shows his cards and gives you all the info you need to track it like any large business would. Very forthcoming. Great buying experience and hopefully a great product, which I expect it to be.

  39. Robert Roll (verified owner)

    The biz!!

  40. Kevin Kawainui (verified owner)

    The Hambini BB’s are the best on the market. I have two on my personal bikes and one on a teammates bike, all perform flawlessly. Hambini engineering and support are topnotch.
