The SRAM Force AXS E1 Rear Derailleur is a high-performance, wireless component that has been refined to be lighter, faster, and more efficient than its predecessors. This specific "36T Max" version is the ultimate all-rounder, designed to handle a wide variety of terrain by supporting cassette ranges from 10-28T up to 10-36T.
By utilizing Orbit fluid damper technology, it provides exceptional chain management, ensuring your drivetrain remains silent and secure whether you're on smooth pavement or hitting rougher, all-road sections.
AXS Enabled: Wireless technology allows for a clean, cable-free setup and easy personalization through the SRAM AXS app.
36T Max Capacity: Specifically engineered to handle larger cogs (up to 36T), providing the low gearing needed for steep climbs and versatile "all-road" riding.
Orbit Fluid Damper: A specialized silicone fluid system that reduces chain bounce and improves shifting precision over bumps and potholes.
Larger X-SYNC Pulleys: Redesigned larger pulley wheels increase drivetrain efficiency and durability by reducing chain articulation.
1x and 2x Compatible: A single cage length works seamlessly with both single-ring and double-ring setups.
Weight Reduction: The E1 update has shed approximately 12g from the previous generation Force derailleur.

Climbing Specialists: If you frequently tackle double-digit gradients, the ability to run a 10-36T cassette provides the "bail-out" gear you need to keep your cadence high.
Clean Build Fans: As a wireless component, it eliminates the need for internal frame routing or messy cables at the rear of the bike.
Mixed-Surface Riders: The Orbit damper is a massive benefit for gravel or poorly maintained roads, keeping the chain from slapping the frame.
Ultra-Wide Gravel Needs: If you want to run the massive 10-44T XPLR cassettes, you will need the specific SRAM Force XPLR AXS derailleur instead.
Mechanical Drivetrain Owners: This is an electronic-only component; it will not work with cable-actuated shifters.
Budget Builds: For a more affordable entry into the AXS ecosystem with similar range, the SRAM Rival AXS is a robust alternative, albeit at a higher weight.
The SRAM Force E1 does not include a battery by default. If you are building a bike from scratch, remember to add a SRAM AXS Battery and charger to your list. Additionally, to ensure the best shifting performance, always use a SRAM Flattop chain with this derailleur, as the tooth profiles on the X-SYNC pulleys are specifically optimized for that chain's unique shape.
