Campagnolo Chorus 12 Rear Derailleur

Technologies

3D Embrace Technology: Movement of the rear derailleur is designed to make the chain embrace more teeth per sprocket to guarantee maximum traction.
Optimised trajectory: Movement of the rear derailleur means that the upper pulley wheel on the cage is always constantly close to the sprocket in use.
12-tooth pulley wheels: Perfect for cassettes that have a wide range of teeth.
Optimised return spring: This guarantees constant chain tension regardless of road vibration.
Features and Benefits

Constant precision: On rough roads, the spring positioned between the upper body and the pivot absorbs the vibrations, ensuring the chain always rests properly on the sprockets.
The pulley wheels on the 12-tooth derailleur cage allow the chain to move more smoothly.
The initial position of the rear derailleur can be adjusted to suit any cassette.
Easy wheel replacement: The rear derailleur is positioned further back, making it easier to slide the wheel out and replace it.
