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.

I needed an additional cassette for a second set of wheels. My setup is primarily Rival with a Force crankset. Since the weight difference does not matter to me, I saw no need for the extra expense to upgrade....this Rival cassette does everything I need it to do.
Purchased this cassette 10-30 for use on the road with Sram AXS 1x. The close gear spacing work well with a 40 tooth chain ring. I live in the flat land so climbing gears are not needed. On the climbing trips I change out the cassette to 10-36 with a 38 chainring.
