SRAM Force XPLR AXS E1 Rear Derailleur – Max 46T

The SRAM Force XPLR AXS E1 Rear Derailleur is purpose‑built for modern gravel riding, where durability, reliability, and precise shifting matter more than anything else. Designed around SRAM’s Full Mount hangerless system, this derailleur delivers consistent performance across rough terrain while virtually eliminating the weaknesses of traditional hanger‑based designs.

Frequently installed during professional gravel bike builds and bicycle servicing across Queensland, the Force XPLR AXS rear derailleur is a dependable upgrade for riders pushing deeper into mixed‑surface and off‑road cycling.

Full Mount Design for Maximum Strength

The Force XPLR AXS rear derailleur uses SRAM’s Full Mount architecture, attaching directly to frames with a UDH (Universal Derailleur Hanger) interface. By eliminating the derailleur hanger entirely, the system improves alignment accuracy and dramatically increases impact resistance.

This design helps prevent damage from rocks, trail debris, crashes, or travel mishaps—making it ideal for riders who race gravel, bikepack, or regularly transport their bikes.

Dedicated 1x Gravel Shifting Performance

This derailleur is 1x specific, engineered exclusively for use with SRAM XPLR 13‑speed 10–46T cassettes and Flattop chains. The straight parallelogram layout ensures accurate chain movement and prevents the derailleur from being forced toward the rear wheel, even in extreme riding conditions.

By focusing solely on 1x drivetrain performance, SRAM has optimised chain retention, shift precision, and long‑term durability for gravel‑specific use.

Simple Setup with No Adjustment Screws

Traditional limit screws are eliminated in the Force XPLR AXS design. When paired with a compatible UDH frame, the derailleur self‑aligns as part of the Full Mount interface, making setup faster and more consistent.

This feature is especially valued by Brisbane bicycle service centres, reducing workshop time while delivering accurate shifting straight out of the build process.

Reliable Chain Management on Rough Terrain

The Force XPLR AXS E1 rear derailleur incorporates advanced chain control technology, maintaining consistent chain tension across corrugations, washboard gravel, and technical descents. This helps keep the drivetrain quiet, secure, and responsive during hard efforts.

Replaceable and rebuildable components further extend the lifespan of the derailleur, making it a practical choice for high‑mileage gravel riders.

Wireless SRAM AXS Integration

As part of the SRAM AXS ecosystem, this rear derailleur offers wireless setup, firmware updates, and customisation via the AXS app. It is compatible with existing SRAM AXS batteries, allowing easy swaps and shared power across compatible components.

Wireless operation also simplifies frame routing and keeps gravel builds clean and uncluttered—an important feature for modern gravel bikes.
