Tools Required
- 4mm and 5mm Allen wrenches [paid link]
- T25 Torx wrench
- eTap battery charger
- Torque wrench
- Screwdrivers (for setting up the derailleur hanger and cable guide, if necessary)
Step-by-Step Installation
- Prepare the Bike: Before installing the rear derailleur, make sure the bike is properly cleaned, and the drivetrain is free from dirt or debris.
- Attach the Rear Derailleur: Use the 5mm Allen wrench to secure the derailleur hanger to the frame. Ensure the derailleur hanger is aligned correctly to avoid any shifting issues.
- Install the Rear Derailleur: Using the T25 Torx wrench, attach the rear derailleur to the derailleur hanger. Tighten the bolt to the manufacturer’s recommended torque specifications.
- Install the Battery: The RED eTap system uses a detachable battery that powers the derailleur. Secure the battery to its designated mount, making sure it is firmly attached.
- Set Up the Chain: Thread the chain through the jockey wheels of the derailleur and onto the cassette. Make sure the chain length is appropriate for your bike setup.
- Pair the Wireless Shifting System: Follow the SRAM eTap pairing instructions to sync the rear derailleur with the shifters. This step ensures that the system will respond correctly to shifting inputs.
Maintenance of the RED eTap 11-speed Rear Derailleur
Maintaining the RED eTap 11-speed rear derailleur is relatively simple due to the absence of cables and housing. However, there are still some critical maintenance steps to ensure the derailleur performs optimally for years to come.
Battery Care
Since the RED eTap 11-speed rear derailleur operates wirelessly, its battery life is crucial. SRAM’s eTap batteries are rechargeable, but it’s essential to regularly check the charge levels to avoid interruptions during rides.
- Charge the battery fully before long rides.
- Store the battery in a dry, cool place when not in use for extended periods.
- Replace the battery every 1-2 years, depending on usage.
Regular Cleaning
Clean the derailleur and surrounding areas regularly to prevent dirt and grime from accumulating. Use a mild degreaser and a soft cloth to wipe down the derailleur after each ride, especially if riding in muddy or wet conditions.
Check for Wear and Tear
Although the RED eTap 11-speed derailleur is built for durability, checking the derailleur hanger for alignment and inspecting the jockey wheels for wear is necessary for maintaining long-term performance.
- Ensure the derailleur hanger is straight to avoid shifting issues.
- Replace the jockey wheels if they show signs of significant wear, such as cracks or excessive roughness.
Troubleshooting Common Set-Up Issues
While the RED eTap 11-speed rear derailleur is designed to offer a reliable experience, certain issues can arise during installation or maintenance. Here are a few common issues and their solutions:
Poor Shifting Performance
- Cause: This could be due to an incorrectly installed derailleur or an issue with the wireless pairing.
- Solution: Recheck the installation process, ensuring all bolts are torqued correctly. Also, ensure that the derailleur is properly paired with the shifters via the eTap system.
Misalignment of the Derailleur
- Cause: A bent or improperly installed derailleur hanger may cause the derailleur to be out of alignment.
- Solution: Use a derailleur hanger alignment tool to check the hanger’s position. If misaligned, gently bend it back into place.
Unresponsive Shifting
- Cause: This is typically caused by low battery power.
- Solution: Charge the derailleur’s battery fully and check that it’s properly connected. If the issue persists, replace the battery.
Customization and Optimization for Better Performance
To get the most out of your RED eTap 11-speed rear derailleur, consider the following adjustments and customizations:
Fine-Tuning the Shifting
Fine-tuning the shifting is critical for ensuring smooth performance across all gears. While the RED eTap system typically requires minimal adjustment, some riders may want to tweak the shifting for optimal performance.
- Adjust the trim on the front derailleur if using a 2x system to ensure precise shifting in all gear combinations.
- Set the maximum and minimum limits on the rear derailleur to prevent the chain from overshooting the cassette.
Adjusting the Battery Position
For adventure riders, the battery’s position can be adjusted to ensure it is securely mounted while maintaining accessibility for recharging. Experiment with different mounting positions to find one that best suits your riding needs.
Comparison with Similar Models
When choosing a rear derailleur for an adventure bike, it’s important to compare different options. The RED eTap 11-speed rear derailleur excels in wireless functionality, making it superior to traditional cable-driven models. However, it’s also useful to consider other high-performance derailleurs like the SRAM Force eTap or Shimano’s Di2 systems.
- SRAM RED eTap offers the wireless system, while SRAM Force eTap may provide a more budget-friendly option with similar features.
- Shimano Di2 offers electronic shifting but requires cables, which may not appeal to riders who prefer the simplicity of wireless systems.
Understanding Compatibility with Other Drivetrain Components
The RED eTap 11-speed rear derailleur is designed to work seamlessly with other SRAM eTap components, including the eTap shifters, power meter, and cranksets. It is also compatible with SRAM 11-speed cassettes, ensuring a smooth, integrated system.
- Ensure that the cassette range and crankset are compatible with the 11-speed drivetrain.
- If mixing with non-SRAM components, ensure compatibility with your chosen shifters and chainrings.
