CAMPAGNOLO RECORD 11 SPEED ULTRA DRIVE CASSETTE

The CAMPAGNOLO RECORD 11 SPEED cassette has been painstakingly designed for shifting performance. A mix of streated steel and titanium cogs keeps shifting precise and reduces the weight to a minimum. An alloy support structure for the rear set helps to improve cog stiffness by 180% and makes the individual cogs 70% more torsionally rigid. This translates straight in to efficiency, with less flex shifts can be quicker and more precise. An improved tooth profile allows for smoother transitions and a nickel-chromed coating resists wear. This shape helps to spread out the stress and improve chain life. material  nickel chromed steel & titanium light alloy supports for the final two triplets compatibility  11-speed Campy drivetrains includes  alloy lockring campagnolo part no  CS9-RE125 made in Italy
