Campagnolo Centaur 10spd Rear GearThe Centaur rear derailleur has been completely Revolutionised compaRed to its predecessor.Absolute precision and reactivity are guaranteed by the new outer plate made of aluminium as per the 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.
