Wide range and tight jumps? Why not both? Our lightest, most durable cassette breaks new ground for gearing choices as well. Four distinct cassette options, including our first 10-30T and 10-36T RED cassettes, each provide secure shift ramps specifically designed for electronic shifting, whether racing road on a 10-28T or creating an all-road setup with a 10-36T. Carefully chosen tooth jumps keep the rider in the right gear when you’re out of the saddle on steep climbs and making fine changes to hold a wheel while approaching a sprint.


  • Designed for smooth and fast shifting
  • Gradual gear progression between cogs — at least five one-tooth jumps on 10-28T, 10 30T and 10-33T cassettes — while still offering a wider range
  • 10-tooth start helps provide a wider gearing range 
  • 10-30T and 10-36T options available in RED for the first time 
  • Designed to work with an XDR driver body
  • One-piece machined steel X-DOME design for weight savings
  • Available in 10-28T, 10-30T, 10-33T and 10-36T
  • Rainbow colorway available in all sizes
