Centaur 11-speed Ultra-Torque? Crank 52/36
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.
The first aluminium crankset with an ULTRA-TORQUE axle: Centaur 11-speed Crank Ultra-Torque? 52/36 from Campagnolo 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.

Technologies Ultra Torque System? Campagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals. Assembly is simplistic: one single oversize bolt is enough to integrate the two semi-axles. With regard to torque transmission efficiency, this system is equally as effective as a single piece axle. Furthermore, despite the narrow side profile, we have been able to position the bearings outside the bottom bracket shell, resulting in greater axle rigidity from the increased axle diameter. This breakthrough was obtained by using an ingenious mechanical system derived from many years’ motoring experience in the rotation axle and engine shaft coupling sector: the Hirth joint. In short , this is a joint with self-centring and self-aligning frontal teeth located in the middle of the bottom-bracket axle where the ends of the semi-axles, integrated with the crankset arms, come into contact.
