If you're moving to SRAM's new 13-speed XPLR platform and need the cassette to match, the Force XPLR E1 XG-1371 is the mid-tier option in that ecosystem — one step below Red and one step above the Rival XG-1351. It's built specifically for 1x 13-speed XPLR drivetrains, offering a 10-46T gear range with tight jumps between gears and a 460% range , and it drops onto a standard XDR driver body so most existing XPLR wheelsets will accept it without any hub changes.

The extra cog compared to 12-speed XPLR isn't just about range — the previous XG-1271 already went 10-44T with 440% range. The 13th sprocket lets SRAM widen to 10-46T while actually tightening the average step between cogs, so you're not giving up cadence smoothness in the middle of the cassette to gain the bailout gear at the bottom. On mixed-surface days where you're spinning up loose climbs one minute and pushing tempo on pavement the next, that closer spacing keeps you from hunting between gears.

Construction is where the Force sits between Rival and Red. Rival cassettes are constructed entirely from stamped steel sprockets, while Force cassettes use aluminum for the largest three cogs to shave weight. Both cassettes use SRAM's circumferentially pinned construction to boost stiffness while also allowing much of the middle of the sprockets to be cut away to save weight . The aluminum big cogs will wear faster than the all-steel Rival version, but that's the tradeoff for the weight savings — and honestly, on a 46T cog that only sees load on the steepest climbs, wear rates are manageable for most riders....
