The workhorse of X-Range™ gearing. The SRAM RED® XG-1290 cassette progresses fluidly and quickly through a wider range of gears. It’s specifically designed for wireless electronic shifting and the one-piece design offers you the best in weight savings.


X-Range - Road bikes are faster and more capable than ever before, and riders are expanding what is possible with drop bar bikes. X-Range is gearing for today’s road riding. SRAM has completely re-imagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings—enabled by AXS. With X-Range, you are always in the right gear. 

X-Dome - X-DOME technology creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life. 

Compatibility - Requires SRAM XDR compatible rear hub.
