What makes the SRAM RED XPLR XG-1391 the top gravel cassette?

The SRAM RED XPLR XG-1391 is the flagship 13-speed gravel cassette, delivering a 10-46t range with 460-percent gear spread and the tightest, most precise shift quality in the XPLR lineup. Shift features on each cog are optimized for electronic shifting, giving you fast, smooth shifts even on rough roads. At just 288g, it's built to the weight standard expected at the RED level. Requires an XDR driver body and is designed for SRAM RED XPLR E1 drivetrains.

RED XPLR is the pinnacle of SRAM's dedicated gravel platform. The XG-1391 brings the same performance obsession found in the RED road lineup to gravel racing and long-distance adventure riding: the range to handle anything, the close steps to keep your power on, and the weight savings that matter when the road goes long.
