Description

The CAMPAGNOLO CHORUS 12V Rear Derailleur embodies Campagnolo's technological excellence and the brand's iconic design, offering performance comparable to the high-end Super Record and Record groupsets.

Although it uses slightly different materials, such as an aluminium cage, it guarantees identical shifting precision and smoothness, for a marginally higher weight.

It integrates the advanced 3D EMBRACE technology, optimising the derailleur's path across larger cassettes. This innovative system maintains perfect alignment on every sprocket and dynamically adjusts the upper pulley in the direction of travel, ensuring ideal contact with the chain.

Thanks to the 12-tooth pulleys, the distance between the derailleur and each sprocket remains constant regardless of the cassette chosen, ensuring efficient, silent and perfectly adapted transmission for demanding cyclists.
