Shimano Ultegra CS-R8100 Cassette

HYPERGLIDE+ cassettes offer a revolutionary off-road shifting system with seamless shifting to both extremes of hot range. Now it's time for the technology to change road cycling too. Even at maximum effort on a climb or in a race with a friend, you don't have to slow down to shift gears.

Shimano ULTEGRA R8150 drivetrains offer maximum efficiency in every gear thanks to larger sprockets and are still compatible with existing HYPERGLIDE freewheel hubs. In addition, ULTEGRA CS-R8100 cassettes now have 12 gears and are the new benchmark for shifting on the road.
