The Campagnolo Chorus 12-speed rear derailleur features 3D Embrace technology and 12-tooth pulley wheels making it suitable for all cassettes as the distance stays optimum on each individual sprocket, regardless of the cassette selected.

Embrace technology not only keeps the rear derailleur vertically aligned in the perfect position for each sprocket, it now makes the upper pulley wheel advance perfectly in the direction the bike is advancing

On rough roads, the spring positioned between the upper body and the pivot absorbs the vibrations, ensuring the chain always rests properly on the sprockets The pulley wheels on the 12-tooth derailleur cage allow the chain to move more smoothly
