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?

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?

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?

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.

  1. Kenny Balterio

    Hambini clearly doesn’t do retail but what he does do is make very good bottom brackets. In this consumer led society I can see why people make fun of his packaging but the small details like a recycled box and a rampant lie on the customs documentation means the end customer doesn’t have to pay import tax. This bottom bracket is ridiculously well made. It went in easily. Pedalling on it is a joy. I didn’t have any creak but I wanted something that was super stiff. This fitted the bill. Buy one, you won’t regret it.

  2. V333Max

    I couldn’t be happier with this BB. The buying experience is a breath of fresh air. No pressure, quick detailed responses and furthermost don’t underestimate the advantage of buying a product from the guy who makes it – it’s priceless. My BB woes have all gone. Total silence. Even under full load in a crit sprint there is no sign of any movement. NTN bearings run super smoothly. It is difficult to put into words how happy I am with this. I have recommended it to all of my cycling buddies. The headline price is a lot but once you try the product and the service, it’s worth every cent.

  3. Bryston Cameron

    I wandered around endless bike forums listening to the usual know it alls before someone directed me over to a complete unknown guy called Hambini who has what I can best describe as a particular style on YouTube where he generally bumbles around northern Europe interspersed with some really good engineering videos. After binge watching, I contacted him with my problem. A swift email exchange later and the (in)famous recycled brown box arrived at my door. Opened the box and **** me it’s like pandora’s cave. It’s beautiful. So smooth and i couldn’t stop touching it. Fitting was easy, everything lined up like a good one and off I went. Immense difference, not a hint of a creak and so stiff to pedal on. A work of art. His bumbling on YouTube is a facade. When he is in engineering mode, he is very switched and a consummate professional. Dealing with him is a breath of fresh air.

  4. Jimmy Klien

    Excellent bottom bracket, delivered quickly, fits well and well made.

  5. M Klein

    I like to support UK manufacturers, so I bought this one. Well priced and well made, went in easily with the press that I also bought from here. I would definitely recommend it. Customer service for answering questions is very good.

  6. melody_racer

    I had a problem where the bottom bracket got destroyed in the post. Another one for an improvement in packaging please… However customer service from Hambini is first rate. New bottom bracket and some other bits sent out straight away. I received them the day after. Usually I think that seller’s don’t give a **** but clearly this one does not, very apologetic and he did all he could to sort me out. As for the bottom bracket, just like everyone else says it’s of the highest order. Beautifully machined and polished finish. Bearings are super smooth, no flex and no creak.

  7. KBerry

    Much stiffer and faster than OEM. Lovely to hold and look at.

  8. ParkLin

    No problems with the packaging. Functional… When you take the bottom bracket out, it is beautiful. It is immediately obvious that this has been designed by someone who is at the top of his game. I bought this on the strength of his youtube channel and like others I was dubious as to whether he was the real deal. No question whatsoever, this bottom bracket is way better than anything else I tried. I took it to the local bike shop to install and watched them install it. The mechanic said it was the best bottom bracket he had come across and wanted to know where I got it from. It is super smooth and on the way home there were no creaks, pops or bangs. When getting on the power, the bottom bracket area feels way stiffer than it did before. It’s hard to describe but it’s like a direct no flex feeling. A word on customer service, no issues and any questions were promptly answered. It’s like having a walking encyclopedic knowledge at the other end of email. Hambini doesn’t have a phone number, I guess that’s because he has a day job. THat’s the only negative point.

  9. NikosKD

    This just works. No fuss and no drama. You can feel the difference as soon as you crank the watts up. Like no other.

  10. DEVe3

    Amazing… Got the PF86 after it was released, slotted in easily and chainline is spot on. I didn’t bother with the loctite and it doesn’t creak at all. You can feel the difference

  11. Henry Atkins

    Another believer, I purchased this to convert from the stock Rotor crank to a Shimano crank. I had contemplated the conversion kits from wheels mfg and praxis but went for this one. I don’t regret it all. It is very well made and you have technical support that is in a league of one. Fast, prompt, courteous. This is how all companies should be. On another note, his YouTube channel rocks.

  12. Matthias K.

    Quick delivery. Wonderful piece of engineering. Thank you very much!

  13. Matthew F.

    fits my Focus Izalco Max perfectly and the cranks practically spin themselves now

  14. James S.

    First rate product & service. This is the second bike that I have put one on.

  15. Steven B.

    On the expensive side , but fits well and rides well, a fw issues with the fit, but al sorted with help from the 5yr old.

  16. dckubler

    Just perfect, Precise enough to be a piece of art. Too bad most of it is hidden by the bike. Installation went smoothly. After putting the cranks on a bonus feature was obvious. The exterior is perfectly smooth, no dirt retaining indentations for a BB wrench.

  17. Martin F.

    Smooth running bottom bracket

  18. Richard J.

    Arrived on time and fitting was pretty straightforward once I got the right loctite and accelerator. No problems so far but only a couple of hundred k’s so far. Happy customer.

  19. Basil H.

    The BB arrived super fast and it came with the important bits that I needed to install. I took it out of the package and admired this incredible piece of engineering – a work of art in every way. I went to the hardware store got a 8 X 1/2 screw with some nuts and washers and I was set. It installed like butter. I will never go back to crap bottom brackets after having experienced the Hambini BB. In true Hambini fashion, the Hambini BB is truly “The Dog’s Dollocks” and worth every penny…

  20. Kelly N.

    It’s perfect! Probably the best-made thing I’ve ever bought. Silenced my click and I am a super happy camper now. Delivery to Denver, CO only took about 6 days as well. Thx Habini!

  21. Jacob J.

    This part shipped to me in the U.S. quickly and flawlessly, and Hambini kept frequent and clear communication throughout the process.

    The Bottom Bracket installation was extremely easy and user friendly, and interfaced my Shimano DXR (Hollowtech II) cranks to my STAAT’S PF30 race frame perfectly.

    The ride is smooth, I feel extremely little resistance pedaling, and there’s no trace of any creaking or related noise.

    Overall, I don’t think you’re going to have an easy time finding a better BB on the market, and I am proud to be sporting Hambini on my dream bike!

  22. martin c.

    The price above is without vat. Still worth it though. A perfectly smooth set of top quality bearings that will last for years if looked after. When they do wear out easilly changed for a new set of top bearings. High quality and well engineered products. Why put cheap shite on your expensive carbon bike when you can have this?

  23. Anonymous

    Product fit and worked perfectly. In addition, Hambini was very responsive in assisting with disassembly of the prior product that this was replacing, that was not a Hambini product. Great customer service and great product.
