Produced from the highest specification carbon fibre, titanium and aluminium to provide maximum functionality at a minimum weight.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.**Ultra-toque system**Campagnolo's most advanced system for translating your organic power into fierce output. A titanium axle and lightweight carbon fibre crankarms give the rider immediate and unbeatable responsivity. Ultra Torque permanently conjoins the semi-axles of the bottom bracket to the respective crankset arms.
