BSA Aluminum Ceramic Bottom Bracket

Our BSA Aluminum Ceramic Bottom Bracket was built to take a beating. It emerged from the Lifetime Unbound XL completely unscathed, in a race where just 59 of 237 starters reached the finish line during the harshest weather conditions in the event's history. That's 356 miles of constant rain, mud, and punishment.

Why? Because we originally developed it for our Frameworks race team, where components are ridden hard, pressure washed constantly, and expected to perform flawlessly all season long. The result is a bottom bracket that keeps running smooth and fast under the toughest conditions—just like Asa Vermette's World Cup-winning debut.

Featuring CNC-machined aluminum bearing cups and an aluminum internal sleeve, paired with premium ceramic bearings, it delivers exceptional durability, efficiency, and long-lasting performance.
