Cassette Shimano Ultegra CS-R8101-12 12s Silver

Hyperglide+ cassettes revolutionised off-road shifting with their smooth upshifts and downshifts.

Now it's time for technology to change road cycling. Even during maximum efforts on a climb or racing among friends, riders no longer need to shift backwards.

In any gear, Ultegra R8150 drivetrains maximise efficiency thanks to larger sprockets and maintain compatibility with existing Hyperglide rear hub bodies. All the while increasing to 12 gears, the Ultegra CS-R8100 cassettes are the new paradigm in road shifting.

• The refined 12-step gear combination provides maximum efficiency and acceleration performance for every race situation.
• Faster, smoother shifting with maximum pedalling force
• Compatible with the new 12-speed and 11-speed road rear hub body
