Features

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 technology - The 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 plate - Extreme stiffness and reduced weight. Increases the precision of the rear derailleur.

Ultra-shift exclusive geometry parallelogram - Maximum 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 bearings - Considerably smooth, they reduce friction and prolong life and shifting performance.
