The new Chorus rear derailleur benefits from the same technology and design as the Campagnolo leader, and as such combines the refinement and performance of the 12-speed Super Record and Record. With just a few minor changes to the materials used in its construction, such as the connecting rod and the outer aluminium shift cage, the Chorus version offers exactly the same performance as the two more expensive groups, while only adding a few grams to its weight.
Chorus brings with it the same higher level technology, like a new optimized trajectory on larger cassettes and the fantastic 3D embrace technology. The latest development in embrace technology not only keeps the rear derailleur vertically in the perfect position for each sprocket but also moves the upper gear roller perfectly forward along the direction of travel of the bike. The 3D embrace technology and the 12-tooth gearshift rollers ensure that the rear derailleur fits all cassettes, as the distance between each individual sprocket remains optimal, regardless of the cassette selected.
When there are irregularities on the road, the spring between the upper body of the rear derailleur and the joint absorbs the vibrations and always provides optimum chain support on the sprockets. The 12-tooth cage's shift rollers ensure smoother chain running. The rear derailleur can be adjusted to suit the cassette in question.
Easy wheel change
The recessed effect of the rear derailleur facilitates the removal and installation of the impeller.
