Cassette SRAM XG-1290 12-speed rainbow

Designed for smooth and fast shifting.

Gradual gear progression between cogs - at least five one-tooth jumps - 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.

All Zipp wheels starting from 2015 are XDR ready.

Rainbow colorway available in 10-28T and 10-33T cassettes.

TECHNOLOGIES

X-DOME - X-DOME technology creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.

Eagle - Eagle technology represents our est 1x drivetrain technology. Eagle is lighter, simpler, more durable, and easier to use drivetrain. Eagle features 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 520%, which is equal to 2x11 drivetrains.

XDR - The XDR driver body is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring rear axle standards, cassette tools or hub redesigns. The XDR interface is 1.85 mm longer than XD and is designed for road hub applications. XDR driver bodies are compatible with all XD cassettes when the casette is installed with a 1.85 mm spacer.
