Chorus pinion
.
Each tooth of the pinion has been developed to achieve the optimal result in terms of synchronization, switching speed and quiet operation.
A double frame system for the six larger sprockets results in extremely high torsional rigidity, thanks to which function remains optimal even when shifting under load.
The surface treatment of the 11 steel sprockets ensures a long service life and ensures consistent precision.
