HYPERGLIDE+ cassettes have revolutionized shifting off-road with perfect shifting and downshifting fluidity. The time has come for technological changes in road cycling. Even during maximum efforts on climbs or racing with a friend, it is no longer necessary to reduce pedal pressure to shift gears. In any gear, ULTEGRA R8150 transmissions maximize efficiency thanks to larger sprockets and maintain compatibility with existing HYPERGLIDE rear hub bodies. All this while moving to 12 speeds and without increasing weight, the ULTEGRA CS-R8100 cassettes are the new frontier for road bikes.
- The refined 12-step progression maximizes efficiency and acceleration performance for all race situations
- Faster and smoother gear shifting even with maximum pedaling force
- Compatible with the new 12-speed and existing 11-speed road rear hub bodies
