SHIMANO ULTEGRA CS-R8101-12 12-speed cassette sprocket

The HYPERGLIDE+ cassette revolutionized off-road gear shifting with seamless shifting and downshifting. The time has come for technological advancements in road cycling. Even when pushing hard on climbs or racing a friend, you no longer need to reduce pedal pressure to shift gears. In any gear, the ULTEGRA R8150 drivetrain maximizes efficiency thanks to larger sprockets while maintaining compatibility with existing HYPERGLIDE rear hub bodies. All this while moving to 12 gears and without increasing weight, the ULTEGRA CS-R8100 cassettes are the new frontier for road bikes.
