Campagnolo Chorus 12s rear derailleur

The Chorus gearbox benefits from the same technology and design as the top of the range Campagnolo and as such incorporates the refinement and performance of the 12-speed Super Record and Record. With only a few minor changes in the materials used in its construction, such as the external aluminum connecting rod and rocker arm, the Chorus version produces exactly the same performance as the two more expensive groupsets, adding only a few grams. Chorus brings with it the same technology as the next level, such as a new trajectory optimized on larger cassettes and the fantastic 3D EMBRACE technology. The latest evolution of Embrace technology not only keeps the derailleur vertically aligned in the perfect position for each sprocket, but now perfectly advances the top wheel along the direction of travel of the bike. 3D EMBRACE technology and 12-tooth sprockets ensure that the derailleur adapts to all sprocket sets as the distance remains optimal on each individual sprocket, regardless of the cassette chosen.

Characteristics

Constant precision In the event of road roughness, the spring between the upper body and the joint absorbs vibrations, always guaranteeing optimal support of the chain on the sprockets. The 12-tooth balance wheels allow for smoother chain movement. Possibility of adjusting the initial position of the gearbox to optimally adapt to each specific sprocket set. Easy wheel replacement. The rearward action of the gearbox allows the wheel to be removed and replaced more easily.
