Campagnolo's Ultra-Torque crank system uses a unique 25mm spindle that mates in the center of the BB shell. Our BSA Campagnolo BB is engineered specifically for this interface — Grade 3 silicon nitride ceramic bearings with DLC-coated races, housed in precision-machined aluminum cups with the correct internal geometry for Ultra-Torque engagement. No adapters, no workarounds. Just the smoothest pedal stroke your Campagnolo cranks have ever delivered.
