The Super Record S Wireless 2x 12-Speed crankset with power meter features the iconic Campagnolo design with visible carbon fiber, for a crankset conceived to deliver maximum accuracy. This crankset with power meter is entirely made of unidirectiiona carbon fiber and uses the Ultra-Torque locking system with a steel axle to transfer all the power applied on the pedals by the cyclist to the transmission. The power exerted on the pedals is measured by a gyroscope that detects your position at all times and has no fewer than 16 extensometers to provide power data that is extremely precise, with an accuracy of +/-1%.
