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. It is 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.
