Cassette Shimano Ultegra CS-R8100-12 12-Speed 11-34D

The HYPERGLIDE+ cassettes revolutionized off-road gear shifting with their smooth shifts, both in upshift and downshift. Now it's time for this technology to change road cycling. Even during maximum efforts on a climb or competing among friends, cyclists no longer need to back off to make a shift. In any gear, the ULTEGRA R8150 transmissions maximize efficiency thanks to the larger sprockets and maintain compatibility with existing HYPERGLIDE hub bodies. All while increasing to 12 gears, the ULTEGRA CS-R8100 cassettes are the new paradigm in road gear shifting.
