1. completely new DeSign:the 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.2. embrace technologytm: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 11-29.3. carbon Fiber cage plate:shifting positioning is exceedingly precise – extremely light.4. Front plate anD cage in carbon Fibre:maximum rigidity, fast actuation and reduced friction.5. upper anD lower boDy in monolithic technopolymer with carbon powDer:maximum lightness yet still resistance to knocks and the elements.6. aluminum Fixing bolt:the two-part system is 53% lighter than steel and 22% lighter than titanium, without compromising resistance and rigidity levels while prolonging component life.
The HO version is suitable for disc brakes
