CeramicSpeed BB ALPHA Road Bottom Bracket - BB30, 68mm, For DUB Spindle is built for riders who demand maximum efficiency and durability from their drivetrain. Designed to perform through years of hard miles, this bottom bracket combines ultra-smooth ceramic performance with robust protection against moisture and contamination.

Hand-built in Denmark, each BB ALPHA features hardened stainless steel races paired with precision grade-3 Silicon Nitride ceramic balls. The result is a bottom bracket that delivers exceptionally low friction and long-lasting performance, even in harsh riding conditions. Up to 500% better moisture protection helps ensure consistent smoothness and reduced maintenance over time.

A simplified spacer tube and lightweight 7075 aluminum cups make installation straightforward while reducing overall weight by 10% compared to previous versions. The optimized bearing placement and redesigned internal race improve stiffness and load handling for more efficient power transfer on every ride.

• Ultra-low friction, high-durability ceramic bearings for smoother pedaling and longer service life
