Installation of the RED eTap AXS (12-speed)

Installing the RED eTap AXS system requires careful attention to detail, as proper setup ensures smooth shifting and optimal performance. The system’s wireless functionality simplifies some aspects of installation but also requires careful positioning and configuration.

Tools Required:

  • 5mm Allen wrench
  • Torque wrench
  • Chain tool
  • Cable cutters
  • 10mm and 11mm wrenches
  • T25 Torx wrench
  • SRAM RED AXS battery charger
  • RED AXS derailleur hanger adapter (if needed)

Installation Steps:

  1. Remove the existing drivetrain components: Remove the old front and rear derailleurs, shifters, and cables if they are present.
  2. Install the RED eTap AXS front and rear derailleurs: Position the derailleurs onto the frame, ensuring the mounting points are correctly aligned. Use a torque wrench to tighten to the manufacturer’s specified torque setting.
  3. Install the AXS shifters: Attach the eTap AXS shifters to your handlebars, ensuring they are positioned comfortably and securely.
  4. Install the crankset: Use the appropriate tools to install your crankset, ensuring the chainring is compatible with the AXS system and that it is installed with the correct torque.
  5. Install the AXS battery: Insert the battery into the derailleur and ensure it is securely connected. Make sure it is charged before proceeding.
  6. Install the chain: Use the chain tool to size and install the chain. The RED eTap AXS is designed for a 12-speed drivetrain, so make sure you use the appropriate 12-speed chain.
  7. Set up the front and rear derailleurs: Using the eTap app, configure the wireless connection between the derailleurs, shifters, and battery. Follow the app’s instructions to finalize setup and ensure wireless communication.
  8. Calibrate the system: Use the eTap app to calibrate the shifting to ensure that both the front and rear derailleurs are properly aligned with the gear cogs.

Adjustment and Maintenance of the RED eTap AXS (12-speed)

Proper adjustment and regular maintenance of the RED eTap AXS system are essential for ensuring smooth, reliable shifting during long gravel rides. Even though the system is low-maintenance due to its wireless nature, periodic checks and minor adjustments can enhance its longevity and performance.

Adjustment Tips:

  1. Front Derailleur Trim Adjustment: The RED eTap AXS offers automatic trim on the front derailleur, but occasionally, manual adjustment may be needed. If you experience chain rub in certain gear combinations, adjust the trim via the AXS app.
  2. Rear Derailleur High and Low Limit Screws: These should be adjusted to ensure that the chain can reach both the smallest and largest cog without overshooting. Proper adjustment prevents shifting issues and ensures the longevity of your cassette and derailleur.
  3. Shifter Reach Adjustment: Customize the reach of your eTap AXS shifters for better comfort on gravel rides. A proper reach ensures effortless shifting, especially when riding on rough, uneven terrain.
  4. Battery Life and Maintenance: Regularly check the battery charge level using the AXS app. Make sure to replace the battery every 1-2 years to avoid unexpected power loss during rides.

Regular Maintenance:

  1. Keep the drivetrain clean: Regularly clean the drivetrain, including the front and rear derailleurs, chain, and cogs. Use a brush and degreaser to remove dirt and grime, which can impair shifting performance.
  2. Lubricate the chain: Use a high-quality chain lubricant suitable for gravel riding to ensure smooth and quiet operation.
  3. Check for worn components: Regularly inspect the chain, cogs, and derailleur for signs of wear. Gravel riding can be rough on the drivetrain, so replacement should be done promptly to avoid shifting issues.

Troubleshooting Common Set-up Issues with RED eTap AXS (12-speed)

Although the RED eTap AXS system is designed for ease of use, some common setup issues may arise. These issues are typically easy to resolve with minor adjustments or simple fixes.

Common Issues and Fixes:

  1. Unresponsive Shifters: If the shifters aren’t responding, ensure that the battery is fully charged. Also, check the wireless connection via the AXS app and re-pair the components if necessary.
  2. Chain Rub: Chain rub can occur if the front derailleur is not properly aligned or trimmed. Use the AXS app to adjust the trim or manually adjust the derailleur positioning.
  3. Skipping Shifts: If the system is skipping shifts, check the derailleur limit screws and ensure the chain is properly sized. Also, inspect the cassette and chainring for wear.
  4. Inconsistent Shifting: If shifting is inconsistent, perform a full calibration via the AXS app. This will realign the derailleurs and ensure that the system is shifting smoothly.
  5. No Shifting Between Cogs: If shifting between cogs isn’t working, it may be due to misalignment of the derailleur hanger. Use a derailleur hanger alignment tool to ensure it is straight.

Customization and Optimization for Gravel Adventures

One of the key advantages of the RED eTap AXS (12-speed) system is its ability to be customized and optimized for gravel riding. By adjusting gearing, fine-tuning components, and choosing the right accessories, gravel riders can achieve the perfect setup for their terrain.

Customization Options:

  1. Wide-Range Cassette: For gravel riders, having a wide-range cassette is crucial for tackling steep climbs and fast descents. Consider using a 10-36T or 10-42T cassette for a broader gear range.
  2. Chainring Selection: Choose the appropriate chainring size based on your gravel riding style. A 40T or 42T chainring paired with a wide-range cassette is ideal for most gravel terrains.
  3. Suspension Seatpost: To further enhance comfort on rough gravel roads, consider adding a suspension seatpost. This will absorb some of the bumps, reducing fatigue during long rides.
  4. Handlebar Shifters: The ability to position the eTap AXS shifters in different places on your handlebars makes it easier to shift while riding. For gravel riding, consider mounting them in positions that suit your riding style, ensuring easy access while riding on rough terrain.

Performance Optimization:

  1. Electronic Shifting Speed: The RED eTap AXS system allows you to adjust the shifting speed. For gravel riders, a quicker shift response can make a significant difference, especially when you need to change gears rapidly on rough trails.
  2. Brake Levers Positioning: The AXS system allows for the adjustment of brake levers to ensure better ergonomics during long gravel rides. Ensure that they are set to reduce hand fatigue and improve control, especially when navigating challenging descents.
  3. Tire Clearance: Gravel riding often involves rough terrain, so it’s essential to choose tires with proper clearance for your frame. The RED eTap AXS system is compatible with wider tires, which will provide better grip and comfort on gravel roads.

Compatibility with Other Drivetrain Components

The RED eTap AXS (12-speed) is designed to be compatible with SRAM’s AXS system, making it easy to integrate with other components in the AXS family. However, compatibility with other drivetrain components should always be checked to ensure smooth operation.

Key Compatibility Considerations:

  1. AXS Batteries and Chargers: The RED eTap AXS system is compatible with other AXS components, including batteries and chargers, which allows for flexibility in maintenance and upgrades.
  2. Crankset and Chainring Compatibility: While the RED eTap AXS works seamlessly with SRAM cranks and chainrings, it can also be compatible with other brands, provided they are designed for 12-speed drivetrains.
  3. Hydraulic Disc Brakes: The RED eTap AXS can be used with SRAM’s hydraulic disc brakes, which provide excellent braking power and modulation for gravel rides. Ensure that the brake system is compatible with your bike’s frame and fork.

Conclusion

The RED eTap AXS (12-speed) system is an excellent choice for gravel riders looking for a reliable, efficient, and customizable shifting experience. Its wireless design, ease of installation, and ability to handle rugged terrain make it perfect for gravel adventures. By understanding its installation, maintenance, and customization options, riders can maximize their performance and enjoy smoother, more enjoyable rides.
