New Super Record S Wireless 12x2 Speed crankset: iconic Campagnolo design with visible carbon fiber for a crankset conceived to deliver maximum performance. The Super Record Wireless crankset is entirely made of carbon fiber and uses the Ultra-Torque locking system with a steel axle to transfer to the transmission all the power exerted on the pedals by the cyclist.

The use of high-quality bearings ensures the now famous smoothness that has become a Campagnolo trademark. The Super Record S Wireless crankset is part of the new transmission designed to offer a wide combination scheme (36/52, 34/50, 32/48, 29/45), which, in synergy with the new cassettes offers the widest spectrum of gear inch ratio.

The ULTRA-TORQUE system completes the specifications, ensuring that all your power translates into extraordinary results. Immediate unstoppable reactivity directed along a steel axle and lightweight cranks in carbon fiber. The chainring has been reworked for efficiency without compromise. Each watt of your power will be transferred to the road.
