BB ALPHA Road Bottom Bracket - BB30, 68mm, For 24mm/Shimano Spindle

CeramicSpeed BB ALPHA Road Bottom Bracket delivers the smooth, durable performance serious road riders expect from a top-tier bottom bracket. Designed for BB30 frames and 24mm Shimano spindles, it combines precision engineering with CeramicSpeed’s signature low-friction performance to keep power transfer efficient and maintenance minimal.

Built to last longer than the frame it’s installed in, the BB ALPHA uses hardened stainless-steel races paired with grade-3 Silicon Nitride ceramic balls for exceptional durability and corrosion resistance. The redesigned bearing placement and updated dust cover system improve sealing and rigidity while reducing wear from contamination. Lightweight 7075 aluminum cups and a simplified spacer tube design make installation straightforward and reduce overall weight by 10% compared to previous generations.

Every BB ALPHA is handbuilt in Denmark for riders who demand efficient power transfer, reliable protection, and the smoothest possible spin on every ride.
