How to Install, Adjust, and Maintain the RED eTap Shifters

The SRAM RED eTap shifters [paid link] represent some of the most advanced and sought-after components in modern road cycling. Known for their wireless functionality, lightweight design, and intuitive shifting performance, these shifters are favored by both professional cyclists and enthusiasts.

If you’re looking to install, adjust, and maintain these shifters for peak performance, this guide will take you through each process step-by-step. Whether you’re a seasoned mechanic or a first-time user, this article will provide you with all the information needed to keep your SRAM RED eTap shifters [paid link] in top condition.


Installation of SRAM RED eTap Shifters

Tools Required:

Steps to Install:

  1. Handlebar Setup: Begin by cleaning and preparing the handlebars. Ensure there’s enough space on the handlebars to place both the left and right shifters. If necessary, remove any existing bar tape or grips.
  2. Attach the Shifters: Slide the RED eTap [paid link] shifters onto the handlebars. Position them in a way that suits your riding style, typically with the brake levers at a comfortable reach.
  3. Secure with Screws: Tighten the shifters to the handlebars using the appropriate Allen wrench [paid link] (usually 5mm). Use a torque wrench [paid link] to ensure they are tightened to the manufacturer’s recommended torque setting (usually around 5–6 Nm).
  4. Install Batteries: Insert the eTap batteries into the shifters. Ensure they are properly seated and secured. The battery compartment is easy to access by sliding it into place.
  5. Run the Cables (Optional): While the eTap system is wireless, you may need to attach your shifters to your derailleur via the wireless link. This usually involves syncing with the eTap system.

Note: When installing, make sure the shifters are aligned properly for both comfort and efficient shifting. The reach to the levers should feel natural to avoid discomfort on long rides.


Adjusting the RED eTap Shifters

After installation, you’ll need to adjust your SRAM RED eTap [paid link] shifters to achieve smooth and reliable shifting. Here’s how to do it:

1. Battery Check and Syncing

Before making adjustments, ensure both shifters have fresh batteries installed and are synced to the front and rear derailleurs. You can check the eTap battery status via the SRAM AXS app.

  • Power on the system and press the buttons to check the battery life.
  • Use the SRAM AXS app to sync the shifters and derailleurs wirelessly.

2. Shifting Performance Adjustments

Once your shifters are connected, you might need to fine-tune the shifting:

  • Front Derailleur Trim: For front derailleur adjustments, use the small trim button on the shifter to fine-tune the position of the front derailleur cage. This is essential to avoid chain rub when shifting.
  • Rear Derailleur Fine-Tuning: Adjust the rear derailleur to ensure smooth shifting between gears. Use the micro-adjustment function available in the SRAM AXS app to fine-tune the rear derailleur position.

3. Brake Levers

Ensure that your brake levers are positioned properly for both braking and shifting. The RED eTap [paid link] shifters combine the brake and shift functions into one unit, so make sure they are aligned comfortably.

4. Shifter Reach and Position

The RED eTap shifters are adjustable in terms of reach (distance from the handlebar). If your hands are too small or too large, adjusting the reach can greatly improve comfort and control.


Maintaining SRAM RED eTap Shifters for Long-Term Performance

Proper maintenance is key to ensuring that your SRAM RED eTap shifters continue to perform at their best. Here’s a guide on how to maintain them:

1. Regular Battery Checks

One of the most important aspects of maintaining the RED eTap shifters is ensuring that the batteries are charged and in good condition.

  • Charge your batteries regularly using the SRAM charger.
  • Always check the battery status before long rides to avoid running out of power during a critical moment.
  • Replace batteries every 1–2 years, or when the system’s performance starts to degrade.

2. Cleaning the Shifters

While the wireless nature of the eTap system reduces the amount of maintenance compared to traditional wired systems, the shifters still need regular cleaning to prevent dirt and grime buildup.

  • Wipe down the shifters with a damp cloth regularly, especially after riding in wet conditions.
  • Be cautious when cleaning around the battery compartments and buttons; avoid water infiltration.

3. Inspect the Shifter Buttons

The button mechanism on the RED eTap shifters should be inspected regularly to ensure it’s still responsive. Over time, excessive use can cause wear, so check the buttons for any sticking or unresponsiveness.

  • If you notice that the buttons aren’t clicking correctly, try cleaning them gently with a microfiber cloth.
  • If the problem persists, you might need to replace the shifters or contact SRAM for support.

Troubleshooting Common Issues with the RED eTap Shifters

1. Unresponsive Shifter

If your shifters are unresponsive, the issue could be due to a low battery or poor syncing between the shifters and derailleurs. To resolve this:

  • Check the battery status using the SRAM AXS app.
  • Ensure that the shifters are properly synced with the front and rear derailleurs.
  • Re-sync the system if necessary.

2. Misalignment of Derailleurs

If your derailleur shifts aren’t clean or consistent, it could be a sign of misalignment. Check the following:

  • Ensure the derailleurs are properly aligned with the chain and cassette.
  • Adjust the derailleur positions using the fine-tuning function in the AXS app.
  • Verify that the derailleur hanger isn’t bent, as this could cause shifting problems.

3. Ghost Shifting

If you experience ghost shifting (when the bike shifts without pressing the shifter), this may be caused by incorrect installation or poor cable tension. To fix this:

  • Check that the shifters are mounted correctly and secure.
  • Make sure the derailleur hanger is straight, and adjust the derailleur cage if necessary.

Customizing the RED eTap Shifters for Better Performance

While the SRAM RED eTap shifters come well-configured from the factory, there are some customizations you can make to optimize performance.

  1. Ergonomics: Adjust the angle of the brake-shifter combo unit to suit your hand position and riding style.
  2. Button Mapping: Using the SRAM AXS app, you can remap the buttons for front and rear derailleur shifting to better suit your preferences.
  3. Brake Lever Feel: You can adjust the brake lever reach to optimize your braking power and comfort.

Conclusion

The SRAM RED eTap shifters offer exceptional performance, but like any high-end component, they require proper installation, adjustment, and maintenance to keep them working like new. By following the steps outlined in this guide, you can ensure that your shifters remain in peak condition for years to come. Regular maintenance, battery checks, and occasional adjustments will help extend the lifespan of your shifters and keep your rides smooth and efficient.
