SRAM XG-1391 XPLR E1 13-Speed Cassette

Description

The SRAM XG-1391 E1 13-speed Cassette was designed to give gravel riders the range to climb anything without giving up tight, responsive gearing when the trail flattens out. A 460 percent gear range — spanning a 10-46t spread — covers steep ascents and fast-paced efforts in a single chainring setup, while the 13-speed configuration keeps jumps between gears small enough that shifting stays precise rather than frantic.

Each cog features optimized shift ramps intended to maintain clean, reliable engagement even when the terrain gets rough underfoot. At 288 grams, the cassette doesn’t carry unnecessary weight. It’s built for XPLR 1x 13-speed rear derailleurs and runs on XDR driver bodies — compatible with all road flat top chains, so integration with a complete 13-speed drivetrain is straightforward.
