Innovative Gearing. Because Hills.

You've been there. You're cranking into a climb and downshift. Your front derailleur drops from the high to low gear, and CLUNK, you lose all your momentum. For all those out there who have suffered this annoyance, put that issue to rest with the SRAM Rival XG-1250 D1 12-Speed Cassette.

X-Range Tech achieves wider range and tighter jumps by going to a 12-speed cassette. This shifts the gear range from the front of the drivetrain to the back.

SRAM's proprietary X-Range design employs smaller chainrings with a consistent 13T difference while giving the cassettes a 10T-start for a wider range (up to 10-36, or 360%!). That means you can stay on the same ring longer, requiring fewer front shifts, which are inherently less efficient than rear shifts. And when a front shift is executed, the smaller jump is smoother and allows you to get to the right cadence with fewer compensation shifts in the rear.

Fewer, faster front shifts make it easier for you to find the right gear, and that's a distinct performance advantage relative to traditional drivetrains.

This new cassette comes in both 10-30T and 10-36T ranges that cover road, gravel, and everything in between.

    Works great

    Run a 10-36 with a 48t 1x for my winter setup in Seattle. Shifts great and is quiet. No issues.
