Ceramic Bottom Bracket T47- 85. 5

Engineered for riders who care about every detail, our ceramic bottom bracket uses ultra-hard silicon nitride ceramic balls paired with precision-matched steel races to reduce friction under load. The result is a smoother drivetrain, faster acceleration, and more efficient power transfer—especially at race cadence. With superior wear resistance and optimized sealing, it delivers consistent performance over time, making it the choice for racers and performance-driven riders who want every watt working for them.
