Built to outlast your frame.
The CeramicSpeed BB ALPHA bottom bracket sets a new benchmark for durability and performance. Featuring hardened stainless-steel races hand-assembled with Grade 3 Silicon Nitride ceramic bearings, it delivers ultra-smooth, low-friction performance with up to 500% better moisture protection.

A new simplified spacer tube design and lightweight cups allow for quick installation and a 10% weight reduction compared to previous generations. Designed to precisely fit Shimano and other 24mm axle cranks on BSA/English threaded frames, the BB ALPHA is made for riders who demand efficiency and longevity.

All CeramicSpeed BB ALPHA models are backed by a lifetime warranty, ensuring unmatched reliability for years of use.
