Sram XG-1290 E1 10-33T 12 Speed Cassette - Rainbow

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.

• Designed for smooth and fast shifting
• Gradual gear progression between cogs — at least five one-tooth jumps on 10-28T, 10-30T and 10-33T cassettes — while still offering a wider range
• 10-tooth start helps provide a wider gearing range
• 10-30T and 10-36T options available in RED for the first time
• Designed to work with an XDR driver body
• One-piece machined steel X-DOME design for weight savings
• Available in 10-28T, 10-30T, 10-33T and 10-36T
