Campagnolo Chorus road derailleur, 12-speed
12-speed road derailleur, for cassette up to 34 teeth, completely redesigned construction, weight 220 g.
12-speed road derailleur Campagnolo Chorus series, completely new construction, enabling control of a cassette with up to 34 teeth on the largest sprocket.
3D EMBRACE technology ensures more precise and smoother shifting and lower energy loss, and thus higher durability of the derailleur. The redesigned parallelogram allows maintaining the same distance between the upper and lower pulley with respect to individual sprockets, whereby the derailleur precisely follows the cassette - this significantly contributes to more precise shifting on all gears.
The shape of the guide has also been completely redesigned, which is now equipped with larger pulleys and contributes to the already excellent shifting performance. The upper pulley differs from the lower one with significantly longer teeth, which help maintain the precise position of the chain with respect to the cassette.
