13-Speed XPLR Performance
The SRAM Rival AXS XPLR E1 Rear Derailleur is engineered specifically for modern 1x gravel drivetrains, delivering precise wireless shifting, exceptional chain control, and robust durability across rough terrain. Optimized for SRAM's 13-speed XPLR ecosystem, it provides the gearing range required for steep climbs, fast gravel sectors, and long-distance mixed-surface riding.
Full Mount Interface
This derailleur uses SRAM's Full Mount attachment standard, eliminating the traditional derailleur hanger and mounting directly to compatible UDH-equipped frames. This design improves impact resistance, increases system robustness, and maintains precise shifting alignment under heavy loads and challenging riding conditions.
Wireless AXS Integration
As part of the SRAM AXS ecosystem, the Rival XPLR E1 Rear Derailleur communicates wirelessly with AXS shifters and accessories. Riders can customize button functions, monitor battery status, and perform firmware updates through the SRAM AXS mobile application.
Chain Management
Advanced chain control technology helps maintain drivetrain security across rough gravel terrain. The derailleur is optimized for SRAM Flattop XPLR chains and is engineered to deliver consistent shifting performance while reducing chain movement on washboard surfaces, rocky roads, and technical gravel sectors.
Compatibility
The Rival AXS XPLR E1 Rear Derailleur is designed exclusively for SRAM's 13-speed XPLR platform. It is compatible with SRAM XPLR 10-46T cassettes, SRAM Flattop 13-speed chains, and SRAM RED, Force, and Rival XPLR E1 AXS controls. A UDH-compatible frame is required for Full Mount installation.
