Campagnolo Chours Rear Derailleur

Chorus™ Rear Derailleurs

The Chorus rear derailleur is compact in design. The parallelogram was designed to assure precise and regular shifting over all ten sprockets. The outer link in carbon fiber, manufactured in-house within Campagnolo’s Composites Department, reduces the weight considerably and provides a racing and hi-tech look. The derailleur pulleys are made from a special material that renders the drivetrain particularly silent.
The rear derailleur is available in three versions:

Short cage derailleur for combining a double/compact crankset with a 13-26 sprocket set or smaller.
Medium cage derailleur for combining a double/compact crankset with a 13-29 sprocket set or smaller or triple crankset with a 13-26 sprocket set or smaller.
Long cage derailleur for combining a triple crankset with a 13-29 sprocket set or smaller.
