Installation of Force XPLR eTap AXS Rear Derailleur

Proper installation is critical to ensuring optimal performance of your Force XPLR eTap AXS rear derailleur. This derailleur is designed for easy setup, but attention to detail is essential.

Tools Required:

  • Torque wrench (for precise adjustments)
  • 5mm Allen wrench
  • T25 Torx wrench
  • Chain checker tool
  • B-screw wrench
  • E-tap AXS charger (to activate the derailleur)

Step-by-Step Installation:

  1. Prepare the Rear Derailleur Hanger: Ensure the rear derailleur hanger is straight. If it is bent, straighten it using a derailleur hanger tool. A misaligned hanger can cause poor shifting performance.
  2. Install the Rear Derailleur: Attach the derailleur to the hanger using the T25 bolt and tighten it to the recommended torque specification (usually 8–10 Nm). Make sure the derailleur is securely mounted.
  3. Connect the Chain: Install the chain through the derailleur’s jockey wheels, ensuring it passes through the correct path. Pay attention to the orientation of the derailleur to prevent unnecessary wear on the components.
  4. Adjust the B-Screw: Set the correct B-screw tension to ensure proper clearance between the derailleur and the cassette. The derailleur should be aligned with the largest cog, with a small amount of space between the teeth and the jockey wheels.
  5. Charge the Derailleur: Before riding, ensure the derailleur is charged using the AXS charger. This will activate the wireless shifting system.
  6. Pair with the AXS System: Using the SRAM AXS app, pair the rear derailleur with your AXS controller. This app helps calibrate the system and configure the shifting preferences.

Adjustment and Maintenance

Fine-Tuning Shifting Performance:

To ensure smooth shifting, you may need to adjust the derailleur’s settings after installation. The Force XPLR eTap AXS features automatic trimming, but fine adjustments might be necessary.

  1. Limit Screws: The derailleur has two limit screws (High and Low) to prevent the chain from dropping off the cassette. Adjust the screws to ensure that the derailleur shifts properly between the smallest and largest cogs.
  2. B-Screw Adjustment: Proper B-screw adjustment is crucial for the best performance. If the derailleur is too close or too far from the cassette, shifting may be sluggish or inaccurate.
  3. Derailleur Alignment: If shifting becomes sluggish or inconsistent, ensure that the derailleur hanger remains straight. A misaligned hanger can lead to poor shifting performance and unnecessary wear on the drivetrain.

Maintenance:

Maintaining your Force XPLR eTap AXS derailleur involves regular cleaning, lubrication, and checking for wear.

  1. Cleaning: Clean the derailleur and jockey wheels after each ride. Use a mild degreaser and a soft brush to remove dirt and debris.
  2. Lubrication: Apply light lubrication to the jockey wheels and pivot points to reduce friction and prolong the lifespan of the derailleur.
  3. Inspect for Wear: Regularly inspect the derailleur for signs of damage or wear. Look for bent parts, worn jockey wheels, or signs of corrosion. If you notice any issues, replace the affected parts promptly to prevent further damage.

Troubleshooting Common Set-Up Issues

While the Force XPLR eTap AXS rear derailleur is designed for easy setup, certain issues can arise. Below are common troubleshooting tips to help you resolve these problems:

1. Poor Shifting Performance:

  • Cause: Misadjusted B-screw or limit screws.
  • Solution: Recheck the B-screw setting and adjust the limit screws for the correct shifting range. Ensure that the derailleur is aligned with the cassette.

2. Erratic Shifting or No Shifting:

  • Cause: Low battery or faulty connection in the AXS system.
  • Solution: Charge the derailleur and ensure it is correctly paired with the AXS app. If issues persist, check for firmware updates or reset the system.

3. Chain Drop:

  • Cause: Incorrect derailleur alignment or poorly set limit screws.
  • Solution: Recheck the derailleur hanger and limit screw adjustments to ensure proper chain retention.

4. Noise During Shifting:

  • Cause: Dirty or dry jockey wheels.
  • Solution: Clean and lubricate the jockey wheels. Also, inspect the chain for excessive wear or debris.

Customization and Optimization for Better Performance

The SRAM Force XPLR eTap AXS rear derailleur can be optimized to match your riding style and terrain. Here are some customization tips:

  1. Gear Range: If you’re riding on challenging terrains like gravel, you might prefer a wider gear range. Consider pairing the Force XPLR with a larger cassette to give you more climbing ability without sacrificing top-end speed.
  2. Chainring Selection: Match the rear derailleur with the appropriate front chainring size. The Force XPLR is compatible with a range of chainring options, so selecting the right combination will optimize your performance.
  3. Shifting Preferences: Customize the shift speed and response through the AXS app to suit your riding preferences. You can adjust how fast or responsive the shifts feel.

Comparison with Similar Models

When considering the Force XPLR eTap AXS rear derailleur, it is important to compare it with similar models in the SRAM lineup, such as the SRAM Red eTap AXS and the SRAM Rival eTap AXS.

  1. SRAM Red eTap AXS:

    • Durability: Offers premium materials and construction, making it highly durable under road cycling conditions.
    • Price: The Red series is more expensive than the Force XPLR, which makes it a better choice for riders seeking the best in weight and performance.
  2. SRAM Rival eTap AXS:
    • Price: More affordable than the Force XPLR, making it a good entry-level option for riders who want eTap AXS performance but with less expense.
    • Durability: The Rival derailleur offers solid performance, but it may not be as robust as the Force XPLR, particularly in off-road conditions.

Why Choose the Force XPLR?

The Force XPLR eTap AXS rear derailleur offers a balanced mix of performance, durability, and cost-effectiveness, especially for gravel and mixed-terrain cyclists. While it may not be as light as the Red eTap AXS, it strikes a solid balance for riders seeking excellent off-road performance without breaking the bank.

Compatibility with Other Drivetrain Components
