Campagnolo Centaur 10Spd rear gear derailleur has been completely revolutionised compared to its predecessor.

Absolute precision and reactivity are guaranteed by the new outer plate made of aluminium as used on the higher level 11s design.

The design of the upper and lower bodies has been optimised to achieve the maximum rigidity and at the same time to reduce the weight.

The cage, too, thanks to the new geometry, is more rigid and lighter, and the silicone rollers reduce vibration and improve the silence of the drivetrain.

Key Features:
- Upper to lower pulley-axle: 55 mm
- Aluminium bodies
- Rollers on bushings
- Lightened special rubber pulleys
- Ultra-Shift aluminum lower and upper body to give less weight, less friction and better shifting precision
- Weight: 220 g
