描述
HYPERGLIDE+ cassettes revolutionized off-road shifting with its seamless shifts both up and down the gear range. Now it’s time for the technology to change road cycling. Even during maximal efforts up a climb or racing a friend, riders no longer need to back off to perform a shift. 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, ULTEGRA CS-R8100 cassettes are the new paradigm in road shifting.
BENEFIT
Refined 12 step gear combination provides peak efficiency and accelerating performance for every racing situation
Faster, smoother shifts under maximum pedaling force
Compatible with new 12-speed and road 11-speed FREEHUB body
