SRAM Rival AXS XPLR E1 Rear Derailleur

The SRAM Rival AXS XPLR E1 rear derailleur is designed for 1x gravel riding with a 10-46T 13-speed cassette. Full Mount mounting with a hangerless interface makes it impact-resistant, while the absence of adjustment screws simplifies setup. It is designed for Flattop chains, so check that your drivetrain is compatible before purchasing.

The MTB-style spring clutch improves chain management, and the parts are replaceable and rebuildable, useful when riding demanding gravel routes. The jockey wheel bearings are steel. The rear derailleur is black. The AXS battery is not included and must be purchased separately if you do not already have one.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
