Speed, precision, lightness and aesthetic refinement: the first rear derailleur with upper and lower carbon fibre body will amaze even the most demanding cyclists.
Totally renewed design
The new shape of the external components allows the rear derailleur to move at a different angle. The new interior design keeps the chain closer to the sprocket package, ensuring better power transmission, stronger and safer traction, better chain/sprocket connection and better durability of components subject to wear.
The special gear inside the rear derailleur body (which acts on a spring with a rectangular cross section) allows the component to move along a path that follows the curve of the sprockets exactly, on cassette 11-23 teeth and as on the new 11-29 cassette.
ALUMINIUM FASTENING SCREW FOR THE DERAILLEUR
The 2-part system, weight reduction of 53 % compared to steel and 22 % compared to titanium with the same strength and stiffness. Longer component life.
Upper and lower rear derailleur bodies in monolithic technopolymer with carbon powder
Maximum lightness while maintaining resistance to shocks and weather conditions.
CARBON FIBRE CAGE
Carbon fibre cage: High rigidity for precise positioning - lowest weight.
Gearshift Controls with Ceramic Bearings
Lowest friction and maximum smoothness increases the service life and performance of the gearshift.
