This rear derailleur stands out due to its combination of cutting-edge technology, smooth shifting capabilities, and versatile design. Whether you’re tackling gravel roads, long-distance touring, or mixed-terrain rides, the Force eTap AXS is built to meet the challenges of any adventure.
Key Features of the Force eTap AXS (12-speed) Rear Derailleur
1. Electronic Shifting
The Force eTap AXS is part of SRAM’s electronic shifting system, which offers quick, precise, and effortless gear changes. With no cables to stretch or maintain, this system ensures consistent performance over time. The derailleur is controlled via wireless signal, offering a clean, streamlined look and reducing the need for regular maintenance associated with traditional cable-operated systems.
2. AXS (Access) Technology
AXS is SRAM’s platform for managing all electronic components. It allows riders to customize shift settings, control the front and rear derailleurs, and monitor battery life directly from the AXS app. This intuitive technology ensures that your shifting system is always optimized for your specific riding style and conditions. You can even personalize button configurations for ease of use on rough terrain.
3. Wide-Range Compatibility
The Force eTap AXS rear derailleur is designed to work with a broad range of cassettes and chainrings, making it a versatile choice for adventure riders. With its 12-speed system, it can accommodate cassettes ranging from 10 to 36 teeth, giving you the flexibility to fine-tune your gear setup according to the demands of your route, whether it’s steep climbs or fast descents.
4. Flawless Shifting Under Load
One of the standout features of the Force eTap AXS derailleur is its ability to deliver flawless shifting even under high load. The derailleur uses SRAM’s Orbit Fluid technology, which significantly reduces chain slap and enhances the system’s responsiveness when shifting. This is especially beneficial for riders on rugged trails or when riding through challenging terrain, where conventional derailleurs may struggle.
5. Durability and Weather Resistance
Designed with adventure riding in mind, the Force eTap AXS derailleur features a sealed construction that is highly resistant to dirt, dust, and water. This makes it particularly suitable for riding in challenging weather conditions, such as rain or mud. The derailleur’s robust design ensures it can withstand the rigors of long-distance rides and tough off-road conditions, providing reliable performance throughout.
6. Lightweight Design
Weighing in at just 272 grams, the Force eTap AXS derailleur offers excellent performance without adding unnecessary weight to your bike. This lightweight construction is crucial for adventure riders looking to maintain efficiency over long rides, as every gram saved translates to improved climbing and overall bike handling.
Installation and Adjustment of the Force eTap AXS (12-speed) Rear Derailleur
Tools Required:
- 5mm Allen wrench
- Torque wrench
- SRAM AXS battery charger
- 2.5mm Allen wrench
- Cable cutters (for trimming the battery mount or any excess wiring)
Installation Process:
- Mount the Derailleur: Begin by attaching the rear derailleur to the derailleur hanger using a 5mm Allen wrench. Make sure the derailleur is aligned properly with the hanger to prevent misalignment during shifting.
- Install the Chain: Install the chain onto the bike, ensuring it passes through the derailleur and is routed correctly. Use the SRAM tool or an appropriate chain tool to shorten the chain if necessary.
- Install the AXS Battery: Secure the battery to the derailleur mount. The Force eTap AXS derailleur comes with a wireless AXS battery that should be charged and properly fitted. Make sure the battery is mounted securely before moving on to the next step.
- Pair the Derailleur with the AXS System: Use the SRAM AXS app to pair the rear derailleur with your system. Follow the on-screen instructions to ensure the derailleur is connected and ready to operate.
- Adjust the Limits: Use the 2.5mm Allen wrench to adjust the high and low limit screws on the derailleur. These screws ensure the derailleur moves correctly across the cassette and does not overshoot or undershoot the gears.
Adjustment Tips:
- Check derailleur hanger alignment before any adjustment to avoid shifting issues.
- Always use a torque wrench when securing components to the recommended torque specifications.
- Regularly update your AXS firmware to ensure the derailleur is operating with the latest performance improvements.
Troubleshooting Common Setup Issues
1. Shifting Issues Under Load
- If you experience poor shifting performance under load, check the derailleur’s battery charge. A low battery can cause weak shifting. Ensure the battery is fully charged and replace it if necessary.
- Ensure the derailleur hanger is properly aligned. An out-of-place hanger can lead to inconsistent shifting performance, especially under load.
2. Slipping or Missed Shifts
- Check the chain length. If the chain is too long, it may cause poor shifting performance or even skipped gears. Shorten the chain accordingly.
- Verify that the derailleur is installed at the correct angle and that the derailleur jockey wheels are not obstructed by any debris or wear.
3. Wireless Connectivity Problems
- If the wireless connection between the rear derailleur and the AXS controller is lost, check the firmware versions for both components and update them if necessary. A weak or disrupted signal may also be due to environmental interference; try reconnecting in a different area.
Customization and Optimization for Better Performance
The Force eTap AXS rear derailleur offers multiple options for riders looking to customize their shifting experience. Some key adjustments and upgrades include:
- Custom Shifting Profiles: Through the AXS app, riders can set custom shift profiles, adjusting the speed and timing of shifts to suit their riding style.
- Changing the Rear Cassette: Riders can swap to a larger or smaller cassette depending on their terrain. The Force eTap AXS works with both wide and standard-range cassettes, providing an ideal gearing setup for various adventures.
- Battery Management: Optimize your battery life by checking the battery status regularly via the AXS app. Consider carrying a spare battery for longer rides if your adventures take you far from charging stations.
Compatibility with Other Drivetrain Components
The Force eTap AXS rear derailleur is designed to be compatible with a range of other SRAM AXS components. However, it’s essential to ensure the entire drivetrain system is eTap AXS-compatible to guarantee seamless performance. This includes matching the rear derailleur with a compatible AXS shifter, crankset, and chainring. Additionally, while the Force eTap AXS is primarily built for road and gravel setups, it can also be used with MTB drivetrains, though some components may require adapters or specific tuning for optimal performance.
By ensuring all components are designed to work together, riders can achieve the best possible performance from their drivetrain, reducing the chances of compatibility issues. Additionally, the use of AXS technology across multiple components allows for better integration and easier customization.
Conclusion
The SRAM Force eTap AXS (12-speed) rear derailleur is a powerful and versatile component for adventure riders who demand precision, durability, and customization. With its electronic shifting, AXS platform, and wide-range compatibility, it provides an optimized solution for tackling various terrains. By following the proper installation procedures, performing regular maintenance, and troubleshooting common issues, riders can maximize the performance of their Force eTap AXS system and enjoy a smooth, efficient riding experience, no matter where the adventure leads.
