CAMPAGNOLO CHORUS 11 SPEED ULTRA-DRIVE CASSETTE

The CAMPAGNOLO CHORUS 11 SPEED cassette has been painstakingly designed for shifting performance. 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 steel - nickel-chromed finish light alloy supports for the final two triplets compatibility 11-speed Campy drivetrains includes alloy lockring made in Italy
