Shimano Ultegra R8101 Cassette 12V 11-34T Linkglide - Silver

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

- Faster, smoother shifting under maximum pedal force
- Suitable for the new 12-speed and 11-speed racing freewheel hub
