Features shimano cassette 12v 11-34t cs-r8101 ultegra
12-step gear combination that provides maximum efficiency and acceleration performance for every racing situation
The seamless shifting experience of the ULTEGRA R8100 12-speed cassette range lets you climb, sprint or flatten without stopping to think about your next gear change. Larger cogs maximize drivetrain efficiency and create compatibility with Shimano's FREEHUB 11- and 12-speed hub bodies.
HYPERGLIDE+ cassettes revolutionized off-road gear shifting with their fluid shifting, both upshifting and downshifting. Now is the time for technology to change road cycling. Even during all-out efforts on a climb or racing with friends, riders no longer need to back up to make a change. In any gear, ULTEGRA R8150 drivetrains maximize efficiency thanks to larger sprockets while maintaining compatibility with existing HYPERGLIDE rear hub bodies. All increasing to 12 gears, the ULTEGRA CS-R8100 cassettes are the new paradigm in road shifting.
