Precision Engineered and Manufactured in the United Kingdom

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 in the United Kingdom. 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.

    Fast shipping, bottom Bracket looks great. Haven’t installed yet. All perfect as described.


    Brilliant service from Hambini. My new BB came really quickly. Turned out that my frame was flawed and I needed a different BB – Hambini offered to take this one back, provided really helpful advice and then proceeded to build me a custom BB to suit my frame. First class.

  3. Peder

    Installed easily on a supersix evo 2016. Runs smoothly, and no creaks:)

  4. Hamilton

    The service and advice I received from Hambini was absolutely perfect. I received replies to my requests right away. Hambini really went out of his way to help me and the BB came with bearings already installed. After watching the install video on youtube, I installed the BB myself. The whole job took me less than 20 min and at the end, the spin test was cherry on the cake. oh! and no more creaking on my Cervelo R5. Thanks a million. Ps. At the next service, my Cervelo R3 will also be treated to a Hambini BB

  5. Matthew Cameron

    Great, creak is gone, easy to fit

  6. peter

    Highly recommend

  7. Greg Masterson

    best BB money can buy. my second one

  8. joel zylstra

    Couldn’t be happier with my Hambini BB. It’s by far a better BB than my old one. It’s quiet and spins very smooth.
    Moreover, Hambini was wonderful to deal with and customer service was top notch.
    Well and truly the lick! ?

  9. William K.

    Excellent bottom bracket and great customer service. U.S. Customs opens every Hambini package to inspect contents. They are not careful when re-taping the box however.

  10. Francisco Franco

    Great product, not installed yet ’cause loctite 641 is out of stock.

  11. Angus B.

    Perfect service. Goods despatched almost immediately.

    I’m pleased with the upgrade from my previous FSA PF30 BB. After using for 200km it’s rock solid, silent and slick by comparison. Do read the installation help guide on the support pages and be prepared in advance once things are measured with a digital caliper. Getting hold of flap wheels, retaining compound and activator AFTER I’d removed the PF30 and measured the frame meant a delay in completing the installation. I whiffled the frame lightly by 0.05mm to meet the tolerance specs and avoid any issues with an overly tight fit. This was simple but a little daunting. Installation was a breeze after that. I contacted Hambini as I needed to remove some of the original adaptors and washers to get back to BB386EVO. Hambini was very quick to respond with helpful advice, which ultimately helped me find the right pre-load. I’d recommend to spin the crankset before tightening to get a feel for how freely it spins, then adjust adaptors and torque within the specified ranges to recreate that same feel without any gaps. That worked a treat and it was not that intuitive when replacing my first bottom bracket. The cost is high but I’m hoping that will be offset in the future with easier bearing replacement and lower stress due to no hammering being required.

  13. Don R.

    Excellent service on an excellent BB

  14. Gary F.

    Fast service and delivery. Amazing quality and attention to detail. Smoothest ever bottom bracket with very very low friction when crank is spun. Next bike will be fitted with Hambini racing bb from new
