Every sprocket tooth has been designed to achieve the maximum synchronization, shifting speed, and silent operation.

The teeth have been designed to optimise the speed and fluidity of shifting. This form reduces stress on the chain which ascends more easily onto the higher diameter sprockets. The large pinions are divided into sets of three and are mounted on a new aluminium frame. Thanks to this, rigidity increases 180% and the individual sprockets are 70% more resistant to torsion.
