Cassette Shimano Ultegra CSR8100 12s 11-34

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 upping to 12 gears, the ULTEGRA CS-R8100 cassettes are the new paradigm in road shifting.
