This bottom bracket features the largest bearings of any commercially available unit for 30mm axles. They are standard 6806 bearings which have a load rating that is significantly higher than the 4030 bearings used by other manufacturers.

Contemporary frames from the likes of Specialized and Cannondale use threaded BSA bottom brackets. This Hambini Ti bottom bracket was designed to address a growing trend of fitting large-format axles (SRAM AXS/DUB and 30mm) into BSA shells. Large-format axles result in thin sidewalls in the threaded regions which cause undesirable bending and twisting. The reduction in cross-sectional area is offset in Hambini Ti Bottom brackets with the use of Titanium which is substantially stronger and stiffer than the aluminium alloys used by other manufacturers.

  1. KEN B.

    I have bought a Hambini BB before and it has been perfect for 15K, I changed the bearings in 2 minutes with the tools and I had little hesitation to buy another one.

    I had mixed expectations as I had not seen a Titanium bottom bracket before buying this one.

    What can I say… It is genuinely unbelievable. The machining in this is another level. This is a completely different league. The usual recycled packaging, no care for the packaging aesthetics, then open the box and you’ll soon forget about the rest of it.

    Service and support are exceptional and frankly that is worth the cost alone

    Fantastically made, My second Hambini BB and this takes it to another level. Much better than the offerings from Hope and Ceramicspeed. It fits perfectly, super smooth and eerily quiet.

    It’s noticeable when you are on load such as sprinting or climbing, the thing just feels super stiff and planted.

  3. Philipp

    It’s the best bottom bracket I’ve used so far, I can pedal really strong, and it still feels as if “all” the kinetic energy is going exactly where it should (rotation of the axle). My bike is designed such that there is extremely tight clearance (~2mm) between the chainstay and the crank arm (for bigger tire clearance), but it doesn’t matter how strong I pedal it doesn’t come too close to it (thanks to a relatively stiff chainstay as well I guess…)

    I’m interested how it will play long-term, but since the bearings are superb (my local bike shop was in awe when seeing the bottom bracket), I guess I’ll be happy for quite some time

    Hambini helped me out greatly with advice to questions I gave and was very responsive in his communication. All in all great doing business with him and would recommend his products to anyone. The machining precision is next level.

Q & A

Two questions: 1.) Is this suitable for a BSA frame for a ROTOR ALDHU Carbon with 30mm axle (road)? 2.) What is the weight? Andreas asked on February 9, 2024

I don't make any guarantees for specific cranksets. It will fit a crankset that is 30mm and has a minimum DBCA of 90mm. If the rotor satisfies that standard then it will fit.
