Campagnolo Chorus 10-speed Cassette

Chorus sprockets use the Ultra-Drive system and are the fruit of continuous research and development to improve our products. The Ultra-Drive system makes shifting more precise and fluid, especially thanks to the careful machining and treatments that the sprocket teeth have undergone. The special sprockets pattern interfaces perfectly with the rest of the drivetrain components, especially the chain and chainrings, thus bringing performance to levels of outstanding excellence. Hardened, nickel chromed cogs and alloy carriers reduce weight while creating a stiffer and more responsive cassette. Fits all Campy 9- and 9-/10-speed hubs from 1997 to present.
