This advanced component is designed specifically for the unique demands of gravel riding, combining cutting-edge technology with rugged reliability. In this guide, we will explore the installation, adjustment, and maintenance of the Rival XPLR eTap AXS, as well as troubleshooting tips, customization options, and comparisons with similar models.

Installation of the SRAM Rival XPLR eTap AXS Rear Derailleur

Installing the SRAM Rival XPLR eTap AXS rear derailleur requires attention to detail to ensure optimal performance. Here is a step-by-step guide to the installation process:

  1. Prepare the bike: Before installing the derailleur, remove the rear wheel and clean the rear derailleur hanger. Check for any damage to the hanger that could affect derailleur alignment.
  2. Attach the derailleur: Position the derailleur on the derailleur hanger and secure it with the provided bolt. Tighten it to the manufacturer’s recommended torque value.
  3. Install the chain: If the chain is not already installed, loop it through the jockey wheels of the derailleur. Make sure it is properly threaded and positioned on the cassette and chainring.
  4. Connect the AXS battery: The Rival XPLR eTap AXS uses a wireless AXS system. Attach the AXS battery to the derailleur, ensuring it clicks into place securely.
  5. Pair the components: Use the AXS mobile app or eTap system to pair the derailleur with the shifters and controller. This wireless pairing is essential for seamless shifting.
  6. Install the rear wheel: Once the derailleur and chain are in place, reattach the rear wheel, ensuring it is seated correctly in the dropouts.

Adjustment of the Rival XPLR eTap AXS Rear Derailleur

Proper adjustment of the Rival XPLR eTap AXS rear derailleur is essential for precise shifting performance. Follow these steps to fine-tune the derailleur:

  1. Set the B-Screw: The B-screw controls the distance between the derailleur and the cassette. Adjust this screw so that the jockey wheel is at the optimal distance from the largest cog, ensuring smooth shifting.
  2. Set the limit screws: The high and low limit screws prevent the derailleur from moving too far inward or outward. Shift the bike to the smallest cog and adjust the low limit screw to ensure the derailleur does not overshift. Similarly, shift to the largest cog and adjust the high limit screw to prevent overshifting in the opposite direction.
  3. Adjust the AXS app: Use the AXS mobile app to fine-tune the shifting. You can adjust the derailleur’s shifting speed, trim settings, and set custom shifting preferences to optimize performance for your riding style.
  4. Test the shifting: Once all adjustments are made, test the shifting across the entire cassette. Make sure the derailleur moves smoothly through all gears without hesitation or skipping.

Maintenance of the SRAM Rival XPLR eTap AXS Rear Derailleur

Regular maintenance is key to keeping your Rival XPLR eTap AXS rear derailleur in top condition. Here are some essential maintenance tasks:

  1. Keep it clean: After every ride, especially on gravel, clean the derailleur to remove dirt, grime, and debris. Use a mild degreaser and a soft brush to avoid damaging the components.
  2. Lubricate the chain: A well-lubricated chain ensures smooth shifting and prolongs the lifespan of the derailleur. Apply chain lube after each ride, especially after riding in wet or dusty conditions.
  3. Check the hanger alignment: The derailleur hanger can bend over time, especially during crashes or impacts. Use a derailleur hanger alignment tool to check that the hanger is straight. If it’s misaligned, the derailleur will not perform optimally.
  4. Inspect the AXS battery: The AXS system uses a rechargeable battery. Check the battery level periodically and recharge it as needed. If the battery is damaged or not holding a charge, it may need to be replaced.
  5. Test shifting performance: Regularly check the derailleur’s shifting performance. If you notice issues such as skipping gears or hesitation, recheck the limit screws, B-screw, and chain condition.

Troubleshooting Common Issues with the Rival XPLR eTap AXS Rear Derailleur

Despite its reliable performance, the Rival XPLR eTap AXS rear derailleur may encounter issues from time to time. Below are some common problems and how to resolve them:

  1. Skipping gears or jumping: This can happen if the chain is worn, or the derailleur is misaligned. Inspect the chain for wear and replace it if necessary. Check the derailleur hanger for straightness and adjust if needed.
  2. Erratic shifting: If the derailleur shifts inconsistently or skips, it could be due to improper AXS pairing, a weak battery, or a dirty derailleur. Re-pair the components, replace the battery if necessary, and clean the derailleur thoroughly.
  3. Derailleur making noise: Noise can be caused by a number of factors, including a misaligned derailleur, a dirty chain, or a worn cassette. Ensure that the derailleur hanger is aligned, and clean or replace the chain and cassette as needed.

Customization and Optimization for Better Performance

The Rival XPLR eTap AXS rear derailleur offers several customization options to tailor its performance to your needs:

  1. Custom shifting profiles: Through the AXS app, you can adjust the shifting speed and trim settings to match your preferred riding style. If you ride fast, you can set quicker, more aggressive shifts. Alternatively, you can soften shifts for a more relaxed riding experience.
  2. Wider gear range compatibility: The Rival XPLR eTap AXS is designed for wider gravel cassettes, making it an ideal choice for gravel and mixed-terrain rides. Consider pairing it with an 11-36T or 10-42T cassette for optimal gearing on challenging gravel climbs and descents.
  3. Battery life management: You can monitor the battery life of your AXS components through the app. If you need extended battery life, you can adjust settings such as shifting speed or even disable some features to conserve power.

Comparison with Similar Models

When choosing a rear derailleur for gravel riding, it’s helpful to compare the Rival XPLR eTap AXS with similar models on the market. Here’s how it stacks up against the competition:

  1. Rival XPLR eTap AXS vs. Force XPLR eTap AXS [paid link]: The Force model is a higher-end option within SRAM’s gravel-specific groupset, offering similar functionality to the Rival XPLR but with lighter materials and more precise shifting. While the Force XPLR is ideal for riders looking for the lightest components and top-tier performance, the Rival XPLR offers a more affordable, robust solution for gravel enthusiasts.
  2. Rival XPLR eTap AXS vs. Shimano GRX Di2: Shimano’s GRX Di2 is another popular gravel-specific electronic drivetrain, known for its reliable performance and smooth shifting. While both systems offer electronic shifting, the Rival XPLR’s wireless design gives it an edge in terms of simplicity and ease of installation, making it a better choice for riders who value a clean setup without additional wires.

Compatibility with Other Drivetrain Components

The Rival XPLR eTap AXS is designed to work seamlessly with other SRAM eTap AXS components, such as shifters, chainrings, and cassettes. When choosing components for your gravel bike, ensure they are compatible with the AXS system. The Rival XPLR is particularly well-suited for wide-range cassettes, making it an excellent choice for gravel riding.

Additionally, the Rival XPLR eTap AXS works best when paired with a compatible 12-speed chain and a dedicated 12-speed gravel cassette. While it may not be directly compatible with some 11-speed systems, it can be used with 11-speed cassettes in certain configurations, but shifting performance may not be optimal.
