Completely new design - The new shape of the external components enables the rear derailleur to move according to a different angle and the new internal design keeps the chain nearer the cassette to ensure better power transmission, greater and more secure traction, a better chain/sprocket interface and greater durability of components subject to wear and tear.

Embrace technologyThe special chainring positioned inside the gear body acts on a rectangular section spring that allows the component to move along a trajectory that perfectly follows the curve of the sprockets, on both the 11-23 cassette and the new 11-29.

Aluminium rear derailleur fastening screws The two-piece system, while maintaining resistance and rigidity, makes it possible to reduce the weight by 53% compared to steel and 22% compared to titanium, and prolongs the life of the component.

Carbon fibre front plateExtreme stiffness and reduced weight. Increases the precision of the rear derailleur.

Ultra-shift exclusive geometry parallelogramMaximum shifting rigidity, fast actuation, precision, friction reduction.

Upper and lower body in monolithic technopolymer with carbon powder Maximum lightness yet still resistance to knocks and the elements.

Carbon fiber cage plate Shifting positioning is extremely accurate and extremely light.

Ceramic ball bearingsConsiderably smooth, they reduce friction and prolong life and shifting performance.
