Sram Cassette - Cassette Xg-1290 E1 12 Speed Silver

Sram Cassette - Cassette Xg-1290 E1 12 Speed SilverSram: Wide range and tight jumps? Why not both? Our lightest most durable cassette 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. Carefully chosen tooth jumps keep you 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.FEATURESDesigned for smooth and fast shiftingGradual gear progression between cogs — at least five one-tooth jumps on 10-28T 10-30T and 10-33T cassettes — while still offering a wider range10-tooth start helps provide a wider gearing range10-30T and 10-36T options available in RED for the first timeDesigned to work with an XDR driver bodyOne-piece machined steel X-DOME design for weight savingsAvailable in 10-28T 10-30T 10-33T and 10-36T SPECIFICATIONSSpeed (CS) 12sGearing 10-28/30/33/36tCog finish (Cassette) Silver/RainbowTechnology (Cassette) XGCog sizes 10-36t:10111213151719212428/32/36Driver body interface XDR
