The Chorus UD 10 speed cassettes use the Ultra-Drive system and are the fruit of continuous research and development to improve 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.
Please Note: The cassette lock-ring is included.
