SRAM Red XPLR E1 Wide AXS 1x13-speed complete groupset

The SRAM Red XPLR E1 Wide AXS groupset for an electronic 1x13-speed gravel drivetrain

The SRAM Red XPLR E1 Wide AXS 1x13-speed complete groupset, with Red XPLR E1 rear derailleur, cassette, crankset, and hydraulic disc brakes with Flat Mount fitting, gets your gravel bike ready for any terrain. The drivetrain is controlled wirelessly for precise, fast shifting, while the hydraulic disc brakes don't just look good — they also deliver powerful stopping performance. Full Mount direct attachment is the rear derailleur's standout feature: it mounts directly to the rear axle instead of the UDH universal derailleur hanger. This keeps it precisely and consistently aligned with zero tolerance, even on rough terrain. The cassette has 13 cogs from 10 to 46 teeth and offers a 460% gear range, ideal for sprints on tarmac, rides on gravel, or climbs in the mountains. The carbon crank arms deliver high stiffness at a low weight. The chainring attaches via Thread Mount and can be swapped out easily with the right tool if needed. The grips are designed to suit different hand sizes and shapes, and both reach and contact point can be adjusted to your needs. Using the AXS app, you can personalize your drivetrain and configure the two additional buttons on the sides of the shift/brake levers.
