Designed in the hands of the athletes. Every single detail has been designed & tested by professional athletes. Obsessed with details, extremely attentive to the riding position & to saving energy, they are the true stars of the development of this product. The Campy-Tech Lab has turned this information in a reality: the Back to Zero position system allows the lever to maintain an optimal position with respect to airflow & allows for less effort for the athlete. The Multi-Shifting System allows, with just one movement, to shift up or down up to 3 cogs at a time! But to fully appreciate all the benefits that the Campagnolo® controls offer, you need to get on the saddle, place your hands & go to beat the clock. Suitable for Potenza, Chorus, Record & Super Record only. Weight: 155g
