  1. Stuart Gregg

    My 2nd Hambini BB, ensures perfect alignment in T47 frames. I ordered mine with full contact bearings as it’s for a gravel bike. I 100% recommend both the Bottom Brackets and customer service.

Q & A

I want to use ROTOR's 2INPOWER ROAD CRANK for factor ostro. Is it possible to install this BB? Will I need shims or sleeves for installation? I would like to see the installation manual if there is one. Goro asked on January 18, 2024

You'd need to take this up with Rotor. The body dimensions are shown in the diagram.
