Description

The Shimano Ultegra CS-R8100 cassette is known for its seamless shifting, ensuring quiet rides and allowing riders to focus entirely on climbs and sprints. This is achieved through Hyperglide+ technology, proven in MTB segments, offering smooth shifting in both directions across the entire gear range.

Even under high effort or in direct competition, smooth upshifting and downshifting are achievable, with larger teeth maintaining maximum efficiency. Additionally, this 12-speed cassette is compatible with Shimano's previous 11-speed freewheel bodies.

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.

 

Features:

  • Lightweight 12-speed HG+ cassette with rigid alloy sprocket carrier for reduced weight and better shifting performance, even under the most demanding gear changes
  • Hyperglide+ sprockets have been designed to reduce weight with improve teeth shaping providing accurate shifting and reduced wear
  • Wide gear range to meet the demands of all types of rider
  • For use with 12-speed chains
