    A recycled cardboard box, no branding, functional packaging. It is the ‘Hambini’ way. The goods inside are of high quality, the fit into the bike is superb. It is clear how the integral sleeve aligns the bottom bracket, the spin is fantastic.

    Don’t be fooled by his antics on YouTube, this is a quality product with service to back it up. I would by another in a heartbeat.

Q & A

Hello, I'm looking for a t47a BB for my Factor bike. I'm using a rotor aldhu crankset with 30 mm axle, do you also offer a version for this size? Andrea Bais asked on June 19, 2022

if you email support@hambini.com, a special can be machined up for you.
