Hambini Bottom Bracket Overview

  • Aerospace Tolerances for a no slop fit
  • One Piece design aligns the bearings perfectly, reducing the likelihood of creak
  • NTN/NSK/SKF/FAG/Koyo Bearings
  • 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. Svenpedller

    Purchased for my wife’s bike. Fitted easily spins beautifully. The finish is perfect. Very professional service

    This BB is absolutely ridiculous. From the getgo, you are on a rollecoaster of craziness. Let’s start off with the non-descript box. Well packed but scruffy. Then we have the packaging which is functional and not bespoke. Once you get through all of that, you end up at the BB and it looks shiny as. Spinning the bearings is like something else. I watched the ‘Hambini’ videos where he talks about clearances and bearings etc and was dubious to say the least as I thought it was a marketing scam. Given the price of it, I plumped for it and I am well pleased. I can’t I wasted my time with 3 local bike shops and multiple trips to halfrauds. 5 stars

    Bought on Sunday, delivered on Tuesday. All questions answered promptly and pictures/drawings to assist me in full. In hindsight if I’d watched the entire video and not skipped some of it I would not have had these problems 🙂 Bottom Bracket is flawless, well designed and machined. Clearly the work of a man who knows his stuff.

  4. MStapleton

    The buying experience was a breath of fresh air. No pressure, all questions answered promptly. Paid, delivered, installed, ride. This BB is much better than the rotor unit it replaced. No flex and spins buttery smooth.

  5. lbbrider

    I can feel the difference on my bike. It is much easier to pedal. Let down by the box.

  6. Stevecarline

    The bottom bracket arrived within days of ordering. My LBS mechanic was excited to get the existing Sram bb out and the Hambini bb in. He has one himself and is a real fan. Once fitted, it spins beautifully and I’ve noticed a difference in the bike’s stiffness. The service from Hambini was first class and I would recommend his products to any serious cyclist.
