Shimano Ultegra R8100 Cassette 11-30T 12S - Silver

HYPERGLIDE+ cassettes offer a revolutionary off-road shifting system with seamless shifting to both extremes of the hot range.
Now it's time for technology to change road cycling too.
Even at maximum effort on a climb or in a competition with a friend, you don't have to slow down to change gears.
Shimano ULTEGRA R8150 drivetrains offer maximum efficiency in every gear thanks to the larger sprockets and are still compatible with existing HYPERGLIDE freehubs.
In addition, ULTEGRA CS-R8100 cassettes now have 12 gears and are the new benchmark for shifting on the road.

- Refined 12-step gear combination delivers optimal efficiency and acceleration performance for any racing situation
- Faster, smoother shifting under maximum pedal force
- Suitable for the new 12-speed and 11-speed racing freewheel hub
