Campagnolo Chorus 12-Speed Rear Derailleur

Campagnolo Chorus 12-Speed Rear Derailleur Campagnolo’s Chorus 12-Speed Rear Derailleur takes a number of features and technologies from their range-topping models for superb shifting at the expense of just a few grams. The single derailleur is compatible with all the Chorus 12-speed cassette options; and the 12 tooth pulleys are optimised to work with the larger sprockets. Chain tension is maintained throughout the gear range even on poor surfaces thanks to the positioning of the return spring that is able to better absorb vibrations. 3D Embrace technology keeps more of the chain wrapped on the sprocket for more efficient drive and less wear on both the chain and the teeth; whilst the rearward location of the derailleur helps make slotting the wheel in and out easier.
