Shimano ULTEGRA CS-R8100 12-Speed Cassette

The Shimano ULTEGRA R8100 12-speed cassette delivers smooth, uninterrupted shifting whether you're climbing, sprinting, or cruising. Built with HYPERGLIDE+ technology, it allows seamless shifting under load—so you never have to back off your effort.

Designed for efficiency and compatibility, the cassette works with both Shimano 11-speed and 12-speed HG freehub bodies, making it an easy upgrade to modern 12-speed drivetrains.

Key Features

  • HYPERGLIDE+ technology for smooth shifting under load
  • 12-speed range for wider gear options
  • Improved drivetrain efficiency with optimized cog sizes
  • Compatible with Shimano 11-speed and 12-speed HG freehubs
  • Consistent performance across climbs, sprints, and endurance rides

Performance Advantage

Unlike traditional cassettes, ULTEGRA R8100 allows shifting even during high power output. Whether you're attacking a climb or accelerating in a sprint, gear transitions remain smooth and controlled.
