NEW UPPER BODY WITH HO (HYDRAULIC OPTIMIZATION) GEOMETRY IN ULTRA-LIGHT TECHNOPOLYMER REINFORCED WITH CARBON FIBRE
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.
