STEEL & TITANIUM FOR AN IDEAL SPROCKET SET. 8 SPROCKETS OF THE RECORD™ SPROCKET SET ARE IN FACT made from STEEL WHILE THE REMAINING 3 ARE IN TITANIUM. The last pair of three sprockets are mounted on a frame with a new structure that increases their rigidity. The steel sprockets have a Nickel-Chrome surface treatment. 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 & 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 & are mounted on a new aluminium frame. Thanks to this rigidity increases 180% & the individual sprockets are 70% more resistant to torsion.11x 11-23 11x 11-25 11x 12-25 11x 12-27 8 steel & 3 titanium
