Shimano 12 Speed 11-30T CS-R8101 Ultegra Cassette

The seamless shifting experience of the ULTEGRA R8101 12-speed cassette range lets you climb, sprint or flat out without stopping to think about your next gear change. Larger sprockets maximize drivetrain efficiency and create compatibility with Shimano's 11- and 12-speed FREEHUB hub bodies.

Shimano 12 Speed 11-30T CS-R8101 Ultrega Cassette

HYPERGLIDE+ cassettes revolutionized off-road shifting with their fluid shifts, both upshifting and downshifting. Now is the time for technology to change road cycling. Even during maximum efforts on a climb or racing with friends, riders no longer need to back off to make a shift. In any gear, ULTEGRA R8150 drivetrains maximize efficiency thanks to larger sprockets and maintain compatibility with existing HYPERGLIDE rear hub bodies. All this increasing to 12 gears, the ULTEGRA11-30T CS-R8101 cassettes are the new paradigm in road shifting.


  • Refined 12-step gear combination provides maximum efficiency and acceleration performance for every racing situation
  • Faster, smoother shifting with maximum pedaling force
  • Compatible with the new 12-speed and 11-speed road REAR HUB body
