Effortless performance. Effortless perfection.

Wide range and tight jumps? Why not both? The lightest, most durable cassette of SRAM breaks new ground for gearing choices as well. Four distinct cassette options, including SRAMs first 10-30 and 10-36 RED cassettes, each provide secure shift ramps specifically designed for electronic shifting, whether racing road on a 10-28 or creating an all-road setup with a 10-36.

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.

Manufacturer's note: Only suitable for use with Flattop® chains.

Technologies of SRAM RED XG-1290:

X-Range

Road bikes are faster and more powerful than ever before, and riders continue to show what bikes with road handlebars are capable of. X-Range™ is the gear ratio for the modern way to ride a road bike. SRAM has completely redesigned the road bike transmission, for more gear range, a more pleasant and more usable gear gradation and thanks to AXS™ also smarter shift settings. With X-Range™ you are always in the right gear.

X-DOME™

The one-piece design of the X-DOME™ technology creates incredibly light, precise and robust cassettes. The open design not only repels dirt better, it also gives the component a longer life and smoother shifting performance.
