Cassette SRAM Red XG-1290 12V - 10-30

The SRAM Red XG-1290 12V cassette is their lightest and most durable cassette that also breaks new ground in gear choice. Specifically designed for electronic shifting, whether for road racing with a 10-28T or for creating an all-terrain setup with a 10-36T. Carefully chosen tooth jumps keep you in the right gear when out of the saddle on steep climbs and making fine shifts to hold a wheel as you approach a sprint.Features:Use: RoadDesigned for smooth and fast shiftingGradual progression between sprockets - at least five one-tooth jumps in the 10-28T, 10-30T, and 10-33T cassettes - while still offering a wider rangeA 10-tooth start helps provide a wider range of gearsDesigned to work with an XDR bodyX-DOME design of a single-piece machined steel to save weightSpeeds: 12
