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

Embrace technology - 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

The new two-part system is 53% lighter than steel and 22% lighter than titanium, without compromising resistance and rigidity levels and prolonging component life

Carbon fiber cage plate results in a shifting positioning that is exceedingly precise and extremely light

Ceramic bearings for a very smooth action that in turn reduces friction, prolongs life and shifting performance
