Description

The ultra-smooth experience of the 12-speed ULTEGRA R8100 range allows you to tackle climbs, sprint, and cover long distances without worrying about gear shifting. The larger sprockets maximize drivetrain efficiency and ensure compatibility with SHIMANO 11 and 12-speed hub bodies.

HYPERGLIDE+ Technology

HYPERGLIDE+ cassettes have revolutionized off-road shifting with perfectly smooth upshifts and downshifts, and now this technology is applied to road cycling as well. Even during maximum efforts on climbs or races, it is no longer necessary to reduce pressure on the pedals to change gears. In any gear, ULTEGRA R8150 drivetrains maximize efficiency thanks to larger sprockets, while maintaining compatibility with existing HYPERGLIDE rear hub bodies. With the move to 12 speeds and no weight increase, ULTEGRA CS-R8100 cassettes represent the new frontier for road bikes.

Key Benefits

  • Maximum Efficiency:The larger sprockets improve the efficiency of the transmission system.
  • Versatile Compatibility:Compatible with SHIMANO 11 and 12-speed hub bodies.
