SRAM RED XPLR AXS (RD-RED-1-E1)

The SRAM RED XPLR AXS (RD-RED-1-E1) represents a paradigm shift in gravel drivetrain technology, specifically engineered for the demands of the modern gravel racer. This "Full Mount" derailleur is designed around the 1x13-speed RED XPLR system, though it maintains the incredible AXS flexibility. By utilizing a Hangerless Interface, the derailleur mounts directly to the bike's wheel axle, creating a connection that is significantly stronger and more precise than traditional hanger-based systems. It features a dedicated Magic Wheel lower pulley—a resilient design that keeps spinning even if a stick or debris becomes lodged in the spokes. With no adjustment screws and a setup process that is more automated than ever, the RED XPLR AXS provides clinical shifting under the most extreme conditions.

Key Features

• Hangerless Interface: Mounts directly to the frame's UDH (Universal Derailleur Hanger) interface for unprecedented strength and perfect alignment.

• 13-Speed Optimized: Designed to work seamlessly with the 10-46T 13-speed XPLR cassette, providing tight jumps where you need them and range where you want it.

• Magic Wheel Pulley: The oversized lower pulley features a secondary inner ring that allows the teeth to continue rotating even if obstructed.

• Full Mount Robustness: Lacks traditional limit screws and B-gap adjustments; the system is "set and forget" once paired and installed via the AXS app.

• Impact Protection: Features an Overload Clutch that protects the wireless motor from side impacts by disengaging and resetting instantly.
