Campagnolo Ekar 13-Speed Rear Derailleur

Campagnolo Ekar 13-Speed Rear Derailleur At the heart of the Campagnolo Ekar groupset is the 13-Speed Rear Derailleur. Tasked with moving the chain across the wide range cassettes on rough terrain; under pressure and in potentially difficult off-road conditions; it uses a 2D parallelogram trajectory design and a clutch to ensure perfect shifts every time. Balancing weight; performance and durability; the materials used include carbon-fibre-reinforced polyamide; alloy and even stainless steel where necessary with the slightly oversized polymer pulley wheels keeping the chain running sweetly onto the cassette. Despite the variety of Ekar cassettes available; the design allows this derailleur to accommodate all the options; whatever their ratios.
