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.

- One-piece machined steel X-Dome design offers strength with weight savings
