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.
