Installation of the Axon Werx Suspension Fork

Installing your Axon Werx suspension fork requires precision and care to ensure optimal performance. The following steps will guide you through the process.

Step 1: Prepare the Bike Frame

Before installing the fork, remove the front wheel and any other components attached to the fork. Ensure that the headset is clean and properly lubricated, as the fork will need to sit smoothly within it.

Step 2: Insert the Fork

Carefully slide the Axon Werx fork into the head tube of the bike frame. Ensure the fork is aligned correctly and positioned to avoid any misalignment with the headset.

Step 3: Install the Stem and Handlebar

Place the stem over the fork’s steerer tube, ensuring the stem is centered. Tighten the bolts using a 5mm Allen wrench, starting with the bolt closest to the headset. Tighten each bolt incrementally to the recommended torque setting (usually 5-6 Nm).

Step 4: Secure the Front Wheel

Install the front wheel, making sure the quick-release lever or thru-axle is properly aligned. Tighten it firmly but not overly so, ensuring the wheel sits securely without any play.

Step 5: Adjust the Headset and Fork Alignment

Once the fork and stem are in place, check the headset for tightness. Adjust the headset preload to eliminate any play in the fork while maintaining smooth rotation.

Adjusting the Axon Werx Fork

The Axon Werx fork comes with both air and rebound adjustments that allow for customization of the fork’s feel and performance. These adjustments are crucial for adapting to different riding conditions and rider preferences.

Air Pressure Adjustment

The Axon Werx features an air spring system. Adjusting the air pressure is key to achieving the correct sag and providing a comfortable ride.

1. Use a shock pump to add air to the positive chamber. The recommended air pressure depends on your rider weight. Refer to the manufacturer’s specifications for optimal pressure settings.
2. After inflating, compress the fork to check the sag. Aim for around 20-25% sag, which is typical for cross-country and trail riding.

Rebound Adjustment

Rebound controls how quickly the fork returns to its original position after compression. A slower rebound offers more control over technical terrain, while a faster rebound provides a more active feel.

1. The rebound knob is located on the bottom of one of the fork legs. Turn it clockwise to slow the rebound and counterclockwise to speed it up.
2. Test the fork on a small bump and adjust until you find the desired response.

Compression Damping (Optional)

If your model includes compression damping adjustments, turn the knob to fine-tune how the fork handles compression. This is especially useful for improving performance on larger impacts.

Maintenance of the Axon Werx Suspension Fork

Routine maintenance is essential to keep your SR Suntour Axon Werx fork in top condition, ensuring it performs consistently throughout its lifespan.

Cleaning and Lubing

After every ride, it’s important to clean the fork to remove dirt and debris, which can wear down seals and reduce fork performance.

1. Use a soft brush to gently clean the stanchions.
2. Wipe the fork legs with a clean, damp rag to remove mud and dirt.
3. Apply a small amount of suspension oil to the stanchions to lubricate the seals and prevent dirt build-up.

Replacing Fork Seals

The seals on the Axon Werx fork can wear over time, leading to oil leakage and reduced performance. Inspect the seals regularly and replace them when necessary.

1. Remove the dust seals carefully using a small screwdriver.
2. Use seal grease to lubricate the new seals before installation.
3. Slide the new seals onto the fork stanchions, ensuring they fit snugly and properly.

Oil Changes

Changing the suspension oil is crucial for maintaining optimal performance, especially if you’ve been riding in wet or muddy conditions.

1. Remove the fork from the bike frame and set it on a stable surface.
2. Drain the old oil from the fork and clean the internals.
3. Refill the fork with fresh suspension oil, ensuring you use the type and quantity recommended by SR Suntour.
4. Reassemble the fork and check for any oil leakage.

Troubleshooting Common Set-Up Issues

While the Axon Werx suspension fork is designed to perform reliably, certain issues can arise during use. Here are some common set-up problems and their solutions.

Fork Is Too Soft or Too Hard

If the fork feels too soft or too hard, it’s likely related to improper air pressure settings.

• Solution: Check the air pressure and adjust according to your rider weight. If the fork feels too soft, add more air; if it feels too hard, reduce the air pressure slightly.

Fork Is Not Returning Properly

If the fork does not return to its full extension after compression, the rebound setting might be incorrect.

• Solution: Adjust the rebound knob to achieve a faster or slower return. Ensure the setting matches your riding style and terrain.

Noisy Fork

Noise can occur if the fork is not properly lubricated or if debris has entered the seals.

• Solution: Clean the fork thoroughly and apply lubrication to the stanchions. If noise persists, check for seal damage and replace if necessary.

Customizing the Axon Werx Fork for Better Performance

Customization of your suspension fork can significantly enhance its performance. Depending on your riding style and the conditions you encounter, certain adjustments can make a noticeable difference.

Adjusting Air Pressure for Different Terrain

For cross-country riding, you’ll likely want a firmer fork with less sag. On the other hand, for more aggressive trail riding, you may want a softer setup with more sag to handle larger impacts.

Tuning Rebound for More Control

For technical descents, slowing down the rebound can help maintain control, while faster rebound can improve the fork’s responsiveness on smooth trails.

Compatibility with Other Drivetrain Components

The Axon Werx fork is compatible with most modern cross-country and trail bike builds. However, it is essential to ensure compatibility with other components, such as the bike frame and headset.

• Headset Compatibility: The Axon Werx uses a straight steerer tube, so ensure your frame has a compatible headset for this type of fork.
• Brake Compatibility: The fork is compatible with both disc brakes and V-brakes. Ensure you have the appropriate mounting system for the brakes you intend to use.

Conclusion

The SR Suntour Axon Werx suspension fork is an excellent choice for riders seeking a balance of performance and durability. By following proper installation, adjustment, and maintenance techniques, you can keep your fork in prime condition for years. Whether you are adjusting the air pressure for comfort, replacing seals, or fine-tuning the rebound, these steps will ensure your fork performs reliably on all your rides.
