Specificatii tehnice:
The form of the teeth is new and they have been treated to increase duration over time. The teeth have been designed to optimize the speed and fluidity of shifting. This form reduces stress on the chain which ascends more easily onto the higher diameter sprockets. The large sprockets are divided into sets of three and are mounted on an aluminium frame. Thanks to this, rigidity increases by 180% and the individual sprockets are 70% more resistant to torsion
