Campagnolo super record 11 speed road cassettethe super record sprocket set exploits a new frame for the two supersize titanium sprocket triplets'. '.strtoupper('t')he strength and resistance to torsion have been increased as a result'. '.strtoupper('t')he design of the teeth strains the chain less.eleven sprockets that are even more efficient despite the reduction of the thicknesses we have succeeded'. '.strtoupper('t')he teeth have been designed to optimize the speed and fluidity of shifting'. '.strtoupper('t')his form reduces stress on the chain which ascends more easily onto the higher diameter sprockets'. '.strtoupper('t')he large pinions are divided into sets of three and are mounted on a new aluminium frame'. '.strtoupper('t')hanks to this, rigidity increases 180% and the individual sprockets are 70% more resistant to torsion.• size 11 speed x 12 25t • 5 steel and 6 titanium sprockets• 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 • new double chain for the larger sprockets • new evolved sprocket timing • weight 177g buy campagnolo components from chain reaction cycles, the world's largest online bike store.
