Description
The excellent shifting quality of the ULTEGRA R8100 R8101 12-speed cassette range allows you to climb, sprint and ride for long periods without slackening off when you think of your next gear change. The drivetrain's larger sprockets maximize efficiency and remain compatible with Shimano 11- and 12-speed freewheel bodies.
The HYPERGLIDE + cassette has revolutionized off-road shifting with smooth shifts both up and down the sprocket range. Now it's time for this technology to change road cycling. Even during maximum effort on climbs or to overtake a friend, riders no longer need to release their thrust on the pedals to make a gear change. Whatever gear is chosen, the Shimano ULTEGRA R8150 transmission maximizes efficiency thanks to larger sprockets and retains compatibility with HYPERGLIDE freewheel bodies. All this while upgrading to 12 speeds. The ULTEGRA CS-R8101 cassette is the quintessential road cycling shifter.
