The Campagnolo Super Record Wireless 12x2 Speed crankset features the iconic Campagnolo design with visible carbon fiber, for a crankset conceived to deliver maximum performance. The Super Record Wireless crankset has a lighter hollow structure and uses the Ultra-Torque locking system with a titanium axle to transfer to the transmission all the force applied on the pedals by the cyclist. The use of ceramic USB bearings ensures the by now famous Campagnolo trademark smoothness. The Super Record Wireless crankset is part of the new transmission designed to offer an innovative combination scheme (34/50, 32/48, 29/45) which, in synergy with the new cassettes offers the widest spectrum of gear inch ratio.
