Setup and Installation
Unboxing and Initial Inspection
Carefully remove the derailleur from its packaging. Verify that all components are present and inspect the derailleur for any signs of damage that may have occurred during shipping.
Installation Steps
- Mount the Derailleur: Securely attach the SRAM X01 Eagle AXS Rear Derailleur to your bike's derailleur hanger. Ensure the hanger is straight and properly aligned.
- Install Battery: Insert the SRAM AXS battery into the derailleur. Push firmly until it clicks into place, indicating a secure connection.
- Pair with AXS Shifter: Turn on your AXS shifter. Press and hold the AXS button on both the derailleur and the shifter until the LED lights flash, indicating successful pairing. Refer to the SRAM AXS app for detailed pairing instructions.
- Chain Installation: Install your 12-speed Eagle chain, ensuring it is routed correctly through the derailleur and is cut to the appropriate length for your drivetrain.
- Limit Screw Adjustment: Adjust the high (H) and low (L) limit screws to prevent the chain from over-shifting the cassette. These screws define the outermost and innermost positions of the derailleur.
- B-Gap Adjustment: Set the B-gap (distance between the upper pulley and the largest cassette cog) using the SRAM B-gap tool. This is crucial for optimal shifting performance across all gears.

Operation
Shifting
The SRAM X01 Eagle AXS derailleur operates wirelessly with your AXS shifter. To shift, simply press the designated shifter paddle. The electronic motor will execute a precise and rapid gear change. The system is designed to provide consistent performance under various riding conditions and loads.
AXS App Customization
Enhance your riding experience by downloading the SRAM AXS app to your smartphone. Connect to your derailleur via Bluetooth to:
- Customize the function of your shifter paddles.
- Monitor battery status for all AXS components.
- Perform firmware updates to ensure optimal performance and access new features.
- Adjust micro-adjustments for fine-tuning shifting precision.
Overload Clutch Protection
The integrated Overload Clutch is a protective feature. In the event of a direct impact to the derailleur, the motor gearbox temporarily disengages, allowing the derailleur to move freely and absorb the force. It then instantly returns to its original position, minimizing potential damage to the derailleur and hanger.
Maintenance and Care
Regular maintenance ensures the longevity and optimal performance of your SRAM X01 Eagle AXS Rear Derailleur.
Cleaning
- After each ride, especially in wet or muddy conditions, clean the derailleur using a mild soap and water solution.
- Avoid directing high-pressure water sprays directly at the electronic components or seals.
- Pay special attention to cleaning the pulley wheels, as accumulated dirt can affect shifting performance.
Battery Care
- Charge the AXS battery regularly using the dedicated SRAM charger.
- Store the battery in a cool, dry place when not in use.
- Avoid fully discharging the battery for extended periods to prolong its lifespan.
Firmware Updates
Periodically check for firmware updates via the SRAM AXS app. Keeping your derailleur's firmware up-to-date ensures you have the latest features and performance enhancements.
Inspection
- Regularly inspect the derailleur hanger for alignment. A bent hanger is a common cause of poor shifting and can be straightened or replaced by a qualified mechanic.
- Check all mounting bolts for proper torque. Refer to SRAM's official documentation for specific torque values.
