SRAM XG-1290 E1 12s Cassette Rainbow

Offering both a wide range and tight jumps, this lightweight and durable cassette sets a new standard for gearing versatility. With four distinct options, including the first-ever 10-30T and 10-36T RED cassettes, it caters to various riding styles. Each cassette is equipped with secure shift ramps specifically designed for electronic shifting, ensuring smooth transitions whether racing on a 10-28T or tackling mixed terrain with a 10-36T. The thoughtfully designed tooth progression keeps riders in the ideal gear—whether powering through steep climbs or making precise adjustments to stay in the draft before a sprint.
