Speed, precision, smoothness and better looks, the Super Record rear mech delivers top-end performance with every shift. With ultralight carbon components & their Embrace Technology, this mech provides better chain/sprocket interface than before.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.
This new technology allows grater engagement of all 11 sprockets thanks to movement, on a more advanced trajectory, that perfectly follows the curve of the cassette.
The heart of this technology is to be found inside the gear, where a special chainwheel (positioned inside) embraces a rectangular section spring, specially sized to achieve the right equilibrium between prompt and smooth shifting. This mechanism enables optimal shifting performance even with extreme combinations, like the new 11-29 cassette.
