Campagnolo Chorus Carbon 12-speed Crank 48/32
Please select a variant to check compatibility
Product information "Chorus Carbon 12-speed Crank 48/32"
The new Campagnolo Chorus 2x12 speed crankset is a true concentrate of technology and versatility. Technically advanced thanks to unidirectional construction technology in carbon fiber, it is produced by direct molding without any surface coating and has an Ultra-Torque steel axle like the Record crankset.
It is versatile thanks to its new ring of 123 mm bolts that, while giving it an extreme-performance structure, also ensures a wider variety of use segments.

Technology
Ultra TorqueCampagnolo 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.
