Campagnolo Power-Torque Bottom Bracket Cups 73x42mm BB30A - High-Performance Bike Crankset Bearings for Road & Mountain Bikes

For use with Athena, Centaur, and Veloce Power-Torque chain sets where the single piece axle is attached to the right-hand arm of the chain set. Careful studies conducted by the Campy Tech Lab engineers allowed material to be removed in zones that could be lightened but at the same time points of stress were strengthened. To make the bottom bracket more efficient the axle has varying thicknesses, obtaining an incredibly light axle while offering absolute rigidity. Maintaining the lateral measurements already defined with Ultra-Torque guarantees maximum compatibility.
