The SRAM RED AXS XG-1290 cassette is an integral part of the RED AXS drivetrain system. With a 10-tooth small cog and X-Range gearing, it progresses fluidly and quickly through a wide range of gears. 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. These cassettes are designed specifically for wireless electronic shifting, and the one-piece design offers exceptional weight savings. The XG-1290 cassette is designed to operate with XDR driver bodies.


  • More gradual gear progression between cogs (at least five one-tooth jumps) while still offering a wider range
  • One-piece machined steel X-Dome design offers strength with weight savings
  • 10-tooth start helps provide a wider gearing range
  • Designed to work with an XDR driver body

Abigail ★★★★★

The 10-tooth cog makes such a noticeable difference on descents—I’m shifting less and carrying speed way better than with my old setup. The gear progression feels buttery through the whole range, and it clicked right into place with no fuss.

Robert W. ★★★★★

Swapped this onto my bike and the 10-tooth cog makes such a difference on the flats—I’m shifting through the range faster than I ever did before. The progression feels buttery smooth, and it’s held up perfectly over a few hundred hard miles so far.
