Installation of the Axon Werx Suspension Fork

Proper installation of the Axon Werx suspension fork is critical to ensure safe and optimal performance. Here’s a step-by-step guide on how to install it correctly.

1. Prepare the Fork and Frame

Before installation, ensure that both your bike’s frame and the suspension fork are clean and free from dirt. Check the frame for any damage that might affect the installation. Clean the steerer tube of the fork and apply a small amount of grease to the upper headset bearings to avoid creaking during rides.

2. Install the Fork into the Headset

  • Insert the fork’s steerer tube into the head tube of the frame.
  • Ensure the fork is aligned properly with the handlebars.
  • Secure the headset compression plug inside the steerer tube, tightening it to the manufacturer’s recommended torque specification.

3. Install the Axle and Wheels

  • Place the wheel into the fork dropouts and tighten the axle using the 15mm spanner wrench.
  • Check the wheel alignment by spinning it and ensuring there are no wobbles.
  • Secure the axle with the correct torque.

4. Tighten the Stem

  • Position the stem on the fork steerer tube.
  • Install the stem bolts and tighten them gradually in a criss-cross pattern.
  • Use a torque wrench [paid link] to ensure you do not over-tighten, as this could damage the fork or stem.

5. Final Checks

  • After installation, check the fork’s function by compressing the suspension and ensuring it moves freely.
  • Verify that the fork is properly secured, and there are no rattles or loose components.

Adjusting the Axon Werx Suspension Fork

The Axon Werx fork allows for several adjustments to suit rider preferences and trail conditions. Key adjustments include the air pressure, rebound, and compression settings.

Air Pressure Adjustment

  • Locate the air valve on the top of the fork’s left leg.
  • Use a shock pump to inflate the fork to the recommended air pressure based on your weight. For cross-country riding, the air pressure should generally fall between 80-100 psi.
  • If you’re unsure of the exact pressure, refer to the manufacturer’s recommendations for your weight and riding style.

Rebound Adjustment

  • The rebound adjuster on the Axon Werx is typically located at the base of the right fork leg.
  • Turn the rebound dial clockwise to slow the rebound or counterclockwise to speed it up.
  • Adjust the rebound to your preference, ensuring the fork returns to full extension without being too slow or fast.

Compression Adjustment

  • The Axon Werx fork also features a compression damping adjustment located on the right leg.
  • Adjust the compression to control how the fork reacts to small bumps and bigger impacts. A stiffer compression setting is suitable for rough terrain, while a softer setting is better for smoother trails.
  • Make small adjustments and test the fork’s performance on the trail to find the ideal setting.

Troubleshooting Common Set-Up Issues

Even with proper installation and adjustments, some common issues may arise during the use of the Axon Werx fork. Here’s how to troubleshoot them.

1. Fork Sticking or Binding

If you notice that the fork feels sticky or binds when compressing, it could be due to dirt or contamination in the seals. Clean the fork legs and seals with isopropyl alcohol. If this does not resolve the issue, you may need to service the seals or replace them entirely.

2. Unresponsive Suspension

An unresponsive suspension can often be traced back to improper air pressure or faulty oil. Check the air pressure and ensure it’s set to the correct level for your weight. If the suspension is still unresponsive, consider a full service to replace the oil or check for internal damage.

3. Noisy Fork

A noisy fork can indicate several problems. First, check that all bolts and components are properly tightened. If the noise persists, it could be due to worn bushings, seals, or an issue with the air spring. Inspect these parts and replace if necessary.

4. Fork Leaking Oil

Oil leakage from the fork’s seals typically happens when the seals are worn or damaged. Inspect the seals for cracks or tears. If damaged, replace the seals with new ones to prevent further leakage and ensure proper performance.

Maintenance Tips for the Axon Werx Fork

Regular maintenance of the Axon Werx fork is necessary to extend its lifespan and ensure optimal performance.

1. Regular Cleaning

  • After each ride, clean the fork using a damp rag and isopropyl alcohol.
  • Make sure the fork legs are free from dirt, debris, and mud, especially around the seals.

2. Fork Lubing

  • Periodically lubricate the stanchions with fork-specific lube to prevent premature wear.
  • Ensure the fork is properly serviced every 50-100 hours of riding, depending on the conditions.

3. Seal Maintenance

  • Inspect the fork seals regularly for damage or wear.
  • If you notice any oil leakage, the seals may need to be replaced. Use a seal press tool to install new seals.

4. Fork Oil Change

  • Depending on usage, you may need to replace the oil inside the fork. The oil change interval for the Axon Werx fork typically ranges from 100-150 hours of riding.
  • Use the recommended suspension oil and follow the manufacturer’s instructions for draining and refilling the oil.

Customizing and Optimizing the Axon Werx Fork

To optimize your riding experience, consider customizing your Axon Werx fork’s settings based on your specific needs.

1. Air Spring Tuning

  • Some riders opt to install a specific air spring designed for their weight or riding style.
  • A firmer air spring offers better support for heavier riders or aggressive terrain, while a softer air spring is better suited for lighter riders or smoother trails.

2. Custom Rebound and Compression Settings

  • Fine-tuning the rebound and compression settings is essential for specific trail conditions.
  • A softer compression setting is ideal for rocky terrain, while a firmer setting works best for smooth singletrack.

3. Upgrade to Better Seals

  • Upgrading to high-performance seals can reduce friction and improve the overall responsiveness of the fork.
  • Consider aftermarket seals that provide better durability and performance in wet or muddy conditions.
