What makes the SRAM RED XG-1290 E1 cassette the next-generation road choice?

The SRAM RED XG-1290 E1 is the updated generation of SRAM's flagship 12-speed road cassette, built for the E1 drivetrain platform. It uses X-DOME technology for a lightweight, one-piece construction and delivers X-Range gearing with wide range and tight jumps, designed so you get the climbing gears you need and the close progression you want on the high end. Available in multiple range options. Requires an XDR driver body and is designed for SRAM E1 road drivetrains.

The E1 generation builds on everything that made the XG-1290 the benchmark road cassette and refines it for SRAM's next-generation drivetrain platform. If you're running RED E1 components, this is the cassette that completes the system.
