Painstaking work was carried out on the sprockets.
The additional speed led Campagnolo to devising a new support structure for the last six sprockets in the two subsets. The form of the teeth is new and they have been treated to increase duration over time.
Eleven sprockets that are even more efficient despite the reduction of the thicknesses?
Campagnolo have succeeded.
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 pinions are divided into sets of three and are mounted on a new aluminum frame. Thanks to this, rigidity increases 180% and the individual sprockets are 70% more resistant to torsion.
