Many top features are packed into the Centaur crankset. The four-arm design allows for independent bolt circles, offering greater stiffness and structural integrity, and also provides additional versatility, as a single crankset is compatible with both standard compact and semi-compact chainrings. Add these features to the first aluminium crankset with an Ultra-Torque axle and the result is a component that is very similar to the top-of-the range part. - Requires use of Ultra-Torque bottom bracket cups-Double standardized bolt circle diameter allows for use of standard, mid-compact and compact chainrings - Ultra-Torque axles couple together in the middle of the BB shell via a Hirth Joint that self centers the crank. This results in a very light weight and stiff system that transfers power to the pedals without power loss - Features Campagnolo X.P.S.S. (eXtreme Performance Shifting System) featuring geometrically optimized chainring teeth. Optimized when mated to a full Campagnolo drivetrain - Ultra-Torque system have both drive and non-drive side bearings pre-installed
