The sprockets must be shaped appropriately for the drivetrain to work perfectly. Each sprocket on this Campagnolo 10-speed cassette has an indented ramp, called Ultra Drive (UD), to assist in upshifting. The Tooth profiles are also custom configured to help with downshifting. The end result is perfect shifting and high-precision operation on every ride.
Please Note: Not compatible with the Wahoo Kickr turbo trainer as this cassette has 8 inner arms. The Wahoo Campagnolo Freehub is only compatible with 4 arm Campagnolo cassettes.
