  • SRAM eTap AXS controller (shifter)

Installation Steps:

  1. Remove the existing derailleur from your bike.
  2. Install the eTap AXS derailleur hanger if your bike does not already have a compatible one.
  3. Attach the derailleur to the derailleur hanger using the provided bolt. Tighten to the recommended torque.

  • B-Screw Adjustment: Set the B-screw to achieve proper derailleur clearance with the largest cog.
  • Derailleur Tension: Use the AXS app to monitor and adjust the derailleur’s tension for precise shifting.

Maintenance of the Force XPLR eTap AXS Rear Derailleur

Routine maintenance of the Force XPLR eTap AXS is essential for long-term performance, especially when riding in rough, gritty conditions. Regularly check for wear on components and make sure the derailleur functions correctly.

  • Chain Maintenance: Clean and lubricate the chain to ensure smooth operation. A well-maintained chain will extend the life of the derailleur and maintain shifting performance.
  • Check for Play: Periodically inspect the derailleur for any loose bolts or play in the system, which could affect shifting precision.

Troubleshooting Common Set-Up Issues

While the Force XPLR eTap AXS derailleur is designed to work efficiently right out of the box, some common setup issues may arise. Here’s how to troubleshoot them:

Poor Shifting Performance:

  • Issue: The derailleur may fail to shift smoothly, especially under load.
  • Solution: Ensure the derailleur cage is properly aligned with the cassette. Double-check the chain length and tension, ensuring it’s appropriate for the cog size. Also, recheck the AXS app settings for any configuration issues.

Dropped Chain:

  • Issue: The chain drops off the cassette when shifting.
  • Solution: Verify the B-screw adjustment to ensure proper clearance between the derailleur and largest cog. Check the limit screws to prevent over-shifting.

Weak or No Shifting Response:

  • Issue: The derailleur is not responding to shifts or shifting is sluggish.
  • Solution: Check the battery charge using the AXS app. If it’s low, recharge or replace the battery. Ensure that the derailleur is paired correctly with the shifter.

Customization and Optimization for Better Performance

The Force XPLR eTap AXS rear derailleur offers several ways to fine-tune and optimize your gravel bike’s performance. Through the AXS app, riders can adjust shifting preferences, monitor bike data, and even tweak gear settings.

Customization Tips:

  • Shifting Speed: Adjust the speed of the shifting response via the AXS app, choosing between fast, moderate, or slower shifting transitions to match your riding style.
  • Cage Positioning: Fine-tune the derailleur cage for optimal chain clearance, which can prevent chain rub during aggressive gravel climbs or technical descents.
  • Battery Monitoring: Use the app to monitor battery performance, ensuring you never run out of power on long gravel rides.

Comparing Force XPLR eTap AXS with Other Gravel Rear Derailleurs
