Campagnolo ULTRA Bottom Bracket Bearings: aerospace-grade ceramics for every pedal stroke.

Silicon nitride ceramic balls selected to aerospace-grade standards, a redesigned high-performance resin cage, and a new dual-seal system: the Campagnolo ULTRA ceramic bearings are the latest evolution of the legendary Ultra-Torque system. Less friction, smoother rotation, greater longevity — a noticeable upgrade with every pedal stroke. Mounted directly onto the crank axle, they deliver real improvements in responsiveness and rotational fluidity, maintaining optimal performance even in the harshest riding conditions.
