Campagnolo Chorus 12-Speed Rear Derailleur

The Campagnolo Chorus 12-Speed Rear Derailleur is the ultimate choice for riders who demand high-performance racing technology with a focus on rugged durability and versatility. Positioned as the "versatile" sibling in the Campagnolo 12-speed family, it utilizes the same 3D Embrace technology found in Super Record models to ensure the upper pulley stays perfectly aligned with each sprocket for maximum power transfer. Built with a carbon-fiber reinforced technopolymer upper and lower body and a solid aluminum cage, it is designed to handle the rigors of gravel, gran fondos, and daily training sessions. For the cyclist who wants the sophisticated 12-speed experience and legendary Italian shifting feel in a robust, dependable package, the Chorus 12s is the perfect match.
