Hambini Racing Bottom Bracket Overview

  • 20% stiffer than Hambini Standard Bottom Brackets
  • As used in the Pro-Peloton
  • Aerospace Tolerances for a no slop fit
  • One Piece design aligns the bearings perfectly, reducing the likelihood of creak
  • NTN Bearings fitted as standard. Ultra Low Friction in Road Applications and Fully Sealed NTN/FAG in MTB Applications
  • No Hammers are required to install or Remove the Bottom Bracket
  • Fully Serviceable, the bearings can be replaced quickly and easily
  • It is supplied with fitting adaptors in M12 (or 1/2 inch), a press or studbar will be required to facilitate installation
  • One year warranty on the bottom bracket body

Precision Engineered

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.

Hassle-Free Maintenance

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 serviced in situ or removed within just a few minutes. The bottom bracket has been designed to be fully rebuildable.

Unrivalled Performance

Unloaded bearing spin tests are a poor measure of frictional performance but they do highlight good bearing alignment. The link below is to a video of a Hambini Racing Bottom Bracket that had completed 10,000km

Class Leading Parasitic Drag Loss (Friction)

The graph below shows 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.

The high torque and low RPM of pedaling causes high Hertzian contact stresses 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.

Bottom Bracket Stiffness

A Hambini BB is a one piece bottom bracket. It actively contributes to the stiffness of the bike’s pedaling 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.

  1. Garth Kane

    Easily the best solution I could find for my BMC. Perfection.

  2. Samuel Hawkins

    I didn’t expect anything less than top notch quality and Hambini delivered on my expectations. A comment from my bike shop mechanic, “these are the best feeling bearings that I have ever experienced”. Zero creak, even sprinting at 1400 watts, and exceptionally smooth performance.

  3. Tom Ruzeu

    I installed the BB as soon as it arrived; couldn’t wait after watching the case study a thousand times. I ran into a major problem where the obstruction in my frame (Giant Defy Advanced SL0) came too soon preventing the cup from clearing to the necked part of the BB. This prevented maneuvering over the obstruction. Since I didn’t buy the Delrin removal tool I made my own out of wood; worked perfectly. Then I took out the Dremel and very slowly removed CF material; after measuring the cup and frame for the amount to be removed. I’ve tried many BB’s over the years (the bike is now 5yrs old, but I love it) including the most recent Enduro TorqTite BB86/92 with XD-15 ceramic bearings, but nothing compares with the smoothness and free spinning of this Hambini BB. In my most humble opinion Hambini’s BBs should be OEM spec’d on all high end bikes. I previously installed Hambini specified NTN bearings on my low end CF wheels and I now don’t even take out my high end CF wheels (plus they’re not TL). Anyway, I’d buy from Hambini just on the impeccable customer service and customer care. Thanks mate.

    Good quality

  7. Paul

    Clearly an outstanding piece of engineering with the feel of ‘quality’ about it. Fitting was straightforward, provided that you have the correct tools (bearing press etc.) and the smooth running is evident from the start (although Hambini says it takes a couple of hundred Km to fully bed the bearings in). I used Loctite as suggested, even though this is a single piece item and as expected all is creak free, even under heavy loads (climbing out of the saddle, sprint efforts etc.). Highly recommended

  8. Michal C.

    Excellent support and BB quality.


    Solid product

  10. Amandip Singh

    Hambini is a legend , he fitted this BB into my asymmetric frame at very short notice. This BB is as smooth as my sack after waxing & stiff AF. Get one, You will not regret it

  11. Chris Kimpton

    No bullshit no daft emails you pay its there the next day

  12. Peter Shepherd

    Just perfect. Great engineering and service. A noticeably stiffer bottom bracket and so smooth. Thank you.

  13. Khalid AL muhairi

    Best quality

    The bike shop destroyed the BB during the Installation in my new bike. They cut it in half, to get it back out. Needless to say, I was not amused. Thus, I cannot give any meaningful feedback. They fitted a Ceramic Speed BB as a replacement (which I wanted to avoid). The contact and purchase with Hambini was excellent, however.
