Engineered to Outlast. Built to Perform. Designed for Speed.

The CeramicSpeed BB ALPHA is the next evolution of bottom bracket performance, a system engineered to last longer than your frame while delivering world-class efficiency. Hand-built with hardened stainless-steel bearing races and grade-3 Silicon Nitride ceramic balls, this bottom bracket sets a new benchmark for durability, smoothness, and protection in the most demanding road, triathlon, and track environments.

Custom-developed seals and precision dust covers provide up to 500% better moisture protection, ensuring consistent performance in all conditions without compromising CeramicSpeed’s famously low friction. A redesigned internal spacer tube and lightweight cup construction reduce overall weight by 10% versus previous generations, while also simplifying installation and long-term maintenance.

Perfectly paired for cranksets with 30mm axles and frames with a pressfit 41mm (BB86) shell, BB ALPHA delivers unmatched efficiency, longevity, and reliability, backed by a lifetime warranty.
