Ultegra R8100 12 Speed Cassette
The Shimano Ultegra CS-R8100 12-Speed Cassette brings Hyperglide+ shifting technology to the Ultegra groupset, delivering seamless gear changes in both directions even under maximum pedalling load, so climbs, sprints and long flat sections can all be ridden without backing off to shift.
Larger driving cogs maximise drivetrain efficiency across the range, dual aluminium spiders keep the overall weight sensible without compromising durability and the nickel-plated steel construction is built to handle the mileage that Ultegra-level riding demands.
The 11-34T range gives you the climbing gears you need for serious terrain while retaining the efficiency and close ratios that make this cassette a practical choice for everything from daily training to race day.
