PAINSTAKING WORK WAS CARRIED OUT ON THE SPROCKETS. The additional speed led us to devising a new support structure for the last six sprockets in 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? We 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 aluminium frame. Thanks to this, rigidity increases 180% and the individual sprockets are 70% more resistant to torsion.
5 steel - nickel-chromed finish for steel sprockets - light alloy carrier - light alloy supports for the final two triplets - 11s timing - 11s tooth machining - 11s light alloy lockring, thread 27x1
- new design toothing
- light alloy lockring
- Nickel-Chrome treatment

The nominal weight does not take account of the sometimes considerable quantities of grease used in the assembly of the products.
