• 6mm Allen wrench [paid link]
• Torque wrench [paid link]
• Grease
• Adjustable spanner
• Star nut tool (if required)
• 20mm axle tool

Step-by-Step Installation

1. Remove the old fork (if applicable):
   • Loosen and remove the headset locknut and top cap using a 5mm Allen wrench.
   • Remove the fork from the frame, ensuring the steerer tube is free of any debris or old grease.
2. Prepare the new Axon Werx fork:
   • Grease the steerer tube to prevent any creaking or binding.
   • If your frame uses a star nut, install it into the steerer tube using a star nut tool.
   • Adjust the fork length to ensure that the axle-to-crown measurement fits your frame’s specifications.
3. Install the fork into the frame:
   • Carefully slide the Axon Werx fork into the frame’s headset, ensuring the bearings are aligned properly.
   • Tighten the headset locknut and top cap to the manufacturer’s recommended torque settings.
4. Install the front wheel:
   • Insert the 20mm axle into the fork’s dropouts and secure it tightly with the appropriate tool.
   • Ensure the axle is properly aligned to avoid any instability during riding.
5. Adjust the settings:
   • Set the fork’s air pressure according to your weight and riding style. The Axon Werx comes with a positive and negative air chamber for precise tuning.
   • Adjust the rebound and compression damping based on your preferences for ride stiffness and responsiveness.

Final Check

Before heading out, double-check all bolts, the axle, and the headset for proper tightness. Ensure there is no play or wobble in the fork. Perform a quick test ride to ensure the fork behaves as expected.

Adjusting and Maintaining the Axon Werx

Proper adjustment and maintenance will keep your Axon Werx fork functioning smoothly for many miles. Regular upkeep ensures it provides the best performance, whether you’re riding aggressively or cruising on smoother trails.

Rebound and Compression Damping Adjustments

1. Rebound Damping:
   • The Axon Werx features a simple dial that allows you to adjust the rebound speed. Turn it clockwise to slow down the rebound and counterclockwise to speed it up.
   • Experiment with settings to find the right rebound speed that offers a controlled yet responsive feel for your riding style.
2. Compression Damping:
   • Compression damping is adjusted by a separate dial located near the top of the fork.
   • Set the compression to a firmer setting for aggressive trail riding and a softer setting for smoother rides. This will allow you to fine-tune the fork’s responsiveness to bumps and obstacles.

Air Pressure Adjustment

The Axon Werx fork uses air springs to adjust the overall feel and stiffness of the suspension. Proper air pressure is crucial for a comfortable ride.

1. Check the recommended air pressure:
   • Use an air pump with a built-in pressure gauge to inflate the positive and negative air chambers. Adjust the air pressure according to your weight and the type of terrain you typically ride.
2. Adjust air pressure over time:
   • As you ride, you may need to make minor adjustments based on changes in riding conditions or if you notice the fork feels too soft or too stiff.

Regular Fork Maintenance

1. Clean the fork regularly:
   • After each ride, wipe down the fork with a soft cloth to remove dirt and grime. Pay attention to the stanchions and seals, ensuring they remain free of debris that could cause damage.
2. Lubricate the stanchions:
   • Periodically, apply a small amount of suspension-specific lubricant to the stanchions to ensure smooth operation and prevent wear on the seals.
3. Service the fork:
   • Every 50-100 hours of riding, or as recommended by SR Suntour, perform a full service on the fork. This includes disassembling the fork, cleaning the internals, and replacing the oil and seals.

Troubleshooting Common Axon Werx Set-Up Issues

While the SR Suntour Axon Werx fork is a high-quality piece of equipment, there are a few common issues riders may encounter. Here’s how to troubleshoot and resolve these problems.

Fork Not Rebounding Properly

If you notice the fork isn’t rebounding properly, it could be due to improper air pressure or the rebound setting being too low.

• Check the air pressure: Ensure both the positive and negative air chambers have the recommended air pressure for your weight.
• Adjust the rebound damping: If the fork is still sluggish, try increasing the rebound speed by turning the dial counterclockwise.

Bottoming Out on Big Hits

If the fork feels bottomed out on large drops or rough terrain, the compression damping might need adjustment, or the air pressure may be too low.

• Increase the compression damping: This will stiffen the fork and prevent it from bottoming out too easily.
• Increase air pressure: Add more air to the positive air chamber to help absorb bigger impacts.

Noisy Fork

If you hear squeaking or grinding noises from the fork, it could be due to contamination on the stanchions or a lack of lubrication.

• Clean the stanchions: Use a soft cloth and suspension-specific cleaner to wipe down the fork’s stanchions.
• Lubricate the seals: Apply a small amount of fork oil to the seals to reduce friction and prevent squeaking.

Customization and Optimization for Better Performance

The Axon Werx fork offers various customization options to tailor the fork to your specific riding needs. Whether you’re looking for better climbing efficiency, improved downhill performance, or just a more comfortable ride, there are several ways to optimize the fork’s settings.

Fine-Tuning Air Pressure

For more aggressive riding, you can adjust the positive air chamber for firmer suspension, providing better control on fast descents. Conversely, for smoother climbs, reduce the air pressure slightly to achieve a softer feel and better traction.

Rebound and Compression Damping

Customizing the rebound and compression settings can improve both comfort and performance. A slower rebound setting is ideal for riders looking to control their fork more precisely, while a faster rebound offers more responsiveness on rough terrain.

Upgrading the Fork

For riders seeking even more performance, upgrading to higher-end parts, such as an upgraded damper or custom tuning options available through SR Suntour, can significantly enhance the fork’s performance for aggressive trail riders.

Comparison with Similar Models

The Axon Werx fork competes with several other high-performance forks on the market. Here’s how it compares to some popular alternatives.
