Campagnolo super record 11 speed road cassettethe super record sprocket set exploits a new frame for the two supersize titanium sprocket triplets the strength and resistance to torsion have been increased as a result the design of the teeth strains the chain less 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 ascend
