SRAM RED AXS XG-1290 Cassette 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. Gradual gear progression between cogs—at least five one-tooth jumps—while still offering a wider rangeOne-piece machined steel X-DOME design for weight savingsAll Zipp wheels starting from 2015 are XDR ready Features Designed for smooth and fast shifting 10-tooth start helps provide a wider gearing range Designed to work with an XDR driver body The SRAM RED AXS XG-1290 Cassette is designed for high-performance road cycling Offering a combination of lightweight construction, smooth shifting, and a wide gear range Features smaller jumps between gears, enabling smoother transitions and maintaining a consistent cadence. Versatile gearing setup suitable for both single and double chainring configurations. Combines a machined steel cluster with a lightweight aluminum cog to create a durable yet lightweight cassetteElastomer rings placed between the cogs reduce chain noise and enhance riding quietnessCompatible with SRAM’s XDR driver body, making it suitable for a wide range of wheelsets SRAM RED AXS XG-1290 Cassette SRAM GX Eagle T-Type XS-1275 Cassette SRAM NX Eagle PG-1230 Cassette SRAM GX Eagle XG-1275 Cassette Add to Cart Add to Cart Add to Cart Add to Cart Customer Reviews 4.6 out of 5 stars 107 5.0 out of 5 stars 2 4.7 out of 5 stars 1,058 4.7 out of 5 stars 940 Price $269.99$269.99 $200.00$200.00 $89.00$89.00 $169.99$169.99 Speed (CS) 12s 12s T-Type 12s 12s T-Type Gearing 10-26t, 10-28t, 10-33t 10-52t 11-50t 10-52t Cog finish (Cassette) Rainbow, Silver Black, Silver Black Black, Silver Technology (Cassette) XG XS PG XS Cog sizes 10-26t;10,11,12,13,14,15,16,17,19,21,23,26, 10-28t;10,11,12,13,14,15,16,17,19,21,24,28, 10-33t;10,11,12,13,14,15,17,19,21,24,28,33 10-52t:10,12,14,16,18,21,24,28,32,38,44,52 11-50t:11,13,15,17,19,22,25,28,32,36,42,50 10-52t:10,12,14,16,18,21,24,28,32,38,44,52 Weight Based On Engineering Estimate Engineering Estimate Engineering Estimate Engineering Estimate Weight (g) 445 445 615 445 XDR A specialized freehub body design created to accommodate the needs of modern road and gravel cycling drivetrains. It extends the benefits of the XD driver body Initially developed for mountain biking, to road applications X-DOME X-DOME technology refers to an advanced manufacturing process and design used in the creation of SRAM’s high-end cassettes, particularly in their mountain bike and road bike drivetrains. This technology is aimed at providing exceptional performance, durability, and weight savings. The X-DOME cassettes are machined from a single block of high-grade steel The one-piece construction ensures high precision in the alignment of teeth and spacing The cassettes feature a hollow, open design that significantly reduces weight without compromising strength The open structure helps in clearing mud and debris, which is particularly beneficial for mountain biking in harsh conditions Removing unnecessary material and optimizing the design
