SRAM Red XG-1290 E1 12 Speed 10-33T Rainbow Cassette

Wide range and tight jumps? Why not both? SRAM's lightest, most durable cassette breaks new ground with 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.

• Model ID: CS-XG-1290-E1 with raibow finish
• 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
• Designed to work with an XDR driver body
• One-piece machined steel X-DOME design for weight savings
