Campagnolo Chorus road derailleur 12 sp.
12-speed road derailleur, for cassette up to 34 teeth, completely redesigned construction, weight 240 g.
12-speed road derailleur Campagnolo Chorus series, completely new construction, allowing to control a cassette with up to 34 teeth on the largest pinion.
The 3D EMBRACE technology ensures more precise and gentle shifting and lower energy loss, and the associated longer life of the derailleur. The elaborate parallelogram enables the upper and lower pulleys to be kept at the same distance to the individual pinions, which means that the derailleur exactly copies the cassette - this helps significantly more accurate shifting at all stages.
The shape of the guide has also been completely redesigned, which is newly fitted with larger pulleys and contributes to the already great performance of shifting. The upper pulley differs from the lower one by significantly longer teeth, which help to maintain the exact position of the chain in relation to the cassette.
