Meet the New Paradigm in Road Shifting
The uninterrupted shifting experience of the Ultegra R8100 12-speed cassette range lets you climb, sprint, or cruise without stopping to think about your next gear change. Larger driving cogs maximize drivetrain efficiency and create compatibility with both Shimano 11 and 12-speed freehub bodies.
Hyperglide+ cassettes already revolutionized off-road engagement with seamless shifts up and down the gear range, now that technology has come to road cycling. Even during maximal climbing or sprinting efforts, riders no longer need to let up for precise shifting. In any gear, Shimano Ultegra R8150 drivetrains maximize efficiency thanks to larger cogs and retain compatibility with existing Hyperglide freehub bodies. All this while increasing to 12-gears.
