New 12x Chorus rear derailleur for use with the disc or rim brake groupsets.

The new Chorus rear derailleur benefits from the same technology and design of top-end Campagnolo products, incorporating the sophistication and performances of the 12-speed Super Record and Record. With just a few changes in the materials used for its construction, like the external plate and derailleur cage in aluminum, the Chorus version produces exactly the same performance as the two more expensive groupsets with the addition of just a few extra grams. Chorus brings with it the same technology as the next level up, like the new optimized trajectory on bigger cassettes and fantastic 3D EMBRACE technology. The latest evolution in 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. 3D EMBRACE technology and 12-teeth pulley wheels makes this rear derailleur suitable for all cassettes as the distance stays optimum on each individual sprocket, regardless of the cassette selected.

Hydraulic Optimised (HO) ensures that there is perfect compatibility with hydraulic components.

Campagnolo’s Chorus 11x HO rear derailleur offers all the performance of Record and Super Record rear derailleurs at a fraction of the cost, thanks to trickle-down technology and the utilisation of different materials. In this HO iteration, this Chorus rear derailleur has been optimised for use with disc brakes, offering a perfect chain line with frames that use a 142x12mm thru-axle. With an alloy body, a carbon outer shell, and jockey wheel cage, this 11x Chorus rear derailleur is both immensely durable, while weighing in at a relatively svelte 183g.
