SRAM XG-1290 E1 Rainbow 12-Speed Cassette
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
- 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
Features
- Designed for smooth and fast shifting
- 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
Tight Gear Jumps
The carefully chosen tooth jumps ensure tight gearing transitions
Which help maintain an optimal cadence and make fine adjustments easier, especially during high-intensity efforts like sprints or climbs. These cassettes are our lightest yet, designed for durability and performance, reducing the overall weight of your bike while withstanding the demands of tough rides.
- The secure shift ramps are specifically engineered for smooth and reliable electronic shifting, ensuring quick and precise gear changes
- Whether you are racing on a 10-28T cassette or setting up for all-road conditions with a 10-36T, these cassettes provide the flexibility needed for various riding styles and conditions
- The wide range and tight jumps allow you to stay in the right gear during steep climbs, improving your efficiency and control while out of the saddle

Life is too short for heavy cassettes and this one is a work of art but the price is just a bit more than I wanted to spend (although in the end, I paid it anyway).Still on the fence if 2x was the right way to go with this gravel bike build, hopefully I don't regret it.
