CeramicSpeed BB ALPHA Gravel Bottom Bracket is built for riders who demand lasting performance in the toughest conditions. Designed for English/BSA 68mm shells and SRAM DUB spindles, this bottom bracket delivers exceptional durability, smooth efficiency, and reliable protection against the elements.
