The CeramicSpeed BB ALPHA is a next-generation bottom bracket engineered to deliver unmatched durability, efficiency, and long-term performance. Built with grade-3 Silicon Nitride ceramic bearings and hardened stainless-steel races, it provides exceptionally low friction and up to 500% better moisture protection compared to standard systems.

The redesigned architecture features a simplified spacer tube and lighter bearing cups, resulting in easier installation and a 10% weight reduction versus previous models. Every detail is optimized to enhance pedaling smoothness, power transfer, and resistance to contamination.

Precisely engineered for use with SRAM DUB cranksets (28.99 mm axle) and BSA/English threaded frames, the CeramicSpeed BB ALPHA ensures perfect fit, maximum efficiency, and long-lasting reliability.
