Centaur™ Rear Derailleur: 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, thanks to the new geometry, is more rigid and lighter, and the silicone rollers reduce vibration and improve the silence of the drivetrain.
The exclusive design of the parallelogram makes shifting extremely fast and precise even under stress.
This particular feature, along with the parallelogram, creates the Ultra-Shift™ geometry, the technology that assures the excellent performance of the latest generation of 11-speed and 10-speed drivetrains.
The special form, designed and developed entirely in the Campy Tech Lab™, gives the derailleur an extremely high degree of torsional stiffness. But what’s more, the form makes shifting fast, reactive, and precise in any situation, even under stress. But for the Super Record™ 11-speed rear derailleur, Campagnolo® wanted to enhance the performance features to make it even more unique, using unidirectional carbon fibre for the upper and lower bodies.
The result: the first rear derailleur made entirely of carbon fibre, with a Formula 1 aesthetic and a markedly reduced weight compared to the versions in aluminium. And above all, the overall rigidity of the system is considerably increased, which in terms of performance translates into the best shifting possible to be found on racing bikes.
Enveloping Oversized Plate: makes the rear derailleur extremely rigid – reduces the possibility of play, increasing the life and reliability of the rear derailleur.
Holed cage plate for lower weight: lighter
Special rubber pulleys: reduced friction – less noise
Ultra-Shift™ Exclusive Geometry
Parallelogram: maximum shifting rigidity, fast actuation, precision, friction reduction.
Ultra-shift™ aluminium lower and upper body: lower weight – rigidity – friction reduction – longer component life.
