The CeramicSpeed BB ALPHA is a premium bottom bracket engineered to deliver exceptional longevity, smoothness, and efficiency — built to outperform and outlast even the most advanced bike frames. Featuring hardened stainless-steel bearing races paired with grade-3 Silicon Nitride ceramic balls, it ensures ultra-low friction while providing up to 500% better moisture protection than conventional systems.

Custom-engineered seals and precision-machined dust covers further enhance durability, keeping contaminants out and maintaining optimal rotational performance in all weather conditions.

A redesigned internal structure, including a simplified spacer tube and lighter bottom bracket cups, enables faster installation and delivers a 10% weight reduction compared to earlier CeramicSpeed models.

Perfect for riders seeking maximum drivetrain efficiency, the BB ALPHA is specifically engineered for 24 mm axle cranks from Shimano and other compatible brands, and fits all BSA / English threaded frames with precision.
