RED XG-1290 12-speed cassette

Wide range and tight jumps? Why not both? The lightest, most durable Red XG-1290 cassette from SRAM breaks new ground for gearing choices as well. Four distinct cassette options, including our first 10-30T and 10-36T RED cassettes, each provide secure shift ramps specifically designed for electronic shifting, whether racing road on a 10-28T or creating an all-road setup with a 10-36T.
