Adjusting the X-Fusion Trace36 HLR Suspension Fork

Adjustments to the Trace36 HLR are crucial for tailoring the fork’s performance to your specific needs. Key adjustments include the air spring pressure, compression damping, and rebound damping.

Air Spring Pressure

The air spring in the Trace36 HLR offers adjustability to suit the rider’s weight. To adjust:

  1. Remove the air valve cap located at the top of the fork.
  2. Use a shock pump to add or release air based on the rider’s weight. Check the manufacturer’s recommended air pressure guidelines to find the optimal pressure range.
  3. Reinstall the valve cap securely after adjustment.

Compression Damping

The HLR damper system allows for high and low-speed compression adjustment, which affects how the fork behaves during impacts and small trail chatter.

  1. High-Speed Compression: Use the knob on the left leg of the fork to adjust the high-speed compression. This adjustment controls the fork’s response to large impacts and drops.
  2. Low-Speed Compression: Turn the low-speed compression knob to adjust the fork’s response to slow, steady compressions like pedaling or braking forces. Start with a middle setting and adjust from there based on personal preference.

Rebound Damping

Rebound damping controls how quickly the fork returns to its original position after compression. To adjust:

  1. Turn the rebound knob, usually located on the bottom of the right fork leg.
  2. Turning the knob clockwise slows the rebound, while turning it counterclockwise increases the rebound speed.

Maintenance of the Trace36 HLR Suspension Fork

Regular maintenance is essential to ensure the longevity and performance of the X-Fusion Trace36 HLR fork. Key maintenance tasks include oil changes, cleaning, and seal replacements.

Cleaning the Fork

  1. Wipe down the stanchions with a clean, damp cloth after every ride to remove dirt and debris.
  2. Inspect the stanchions for any signs of damage or wear, such as scratches or dents.
  3. Regularly clean the fork’s lowers to prevent dirt buildup, which can wear down the seals and internals.

Oil and Seal Maintenance

X-Fusion recommends performing oil changes at regular intervals, typically every 50-100 hours of riding. To change the oil:

  1. Remove the fork’s lowers by undoing the appropriate bolts.
  2. Drain the old oil and replace it with fresh oil, following the manufacturer’s specifications for the type and quantity of oil to use.
  3. Replace the seals if necessary to maintain optimal performance and prevent leaks.

Replacing the Seals

Over time, seals may degrade, leading to leaks and poor performance. Replacing seals involves:

  1. Removing the fork lowers as mentioned above.
  2. Gently prying out the old seals with a seal tool or flathead screwdriver.
  3. Installing the new seals, making sure they are oriented correctly and seated properly to prevent leaks.

Troubleshooting Common Issues

Even with proper care, suspension forks can sometimes develop issues. Here are some common problems with the Trace36 HLR and how to address them:

Fork Not Holding Air Pressure

If the fork loses air pressure:

  • Check the air valve and ensure it is tightly closed.
  • Inspect the seals for any damage or wear.
  • If the issue persists, the air spring or seals may need to be replaced.

Excessive Rebound or Compression

If the fork feels too slow or too fast in rebound or compression:

  • Recheck the rebound and compression settings, and adjust them to suit your riding style.
  • If adjustments don’t improve the performance, consider changing the fork oil, as it can thicken or degrade over time.

Noisy Fork

A noisy fork can result from dirt or lack of lubrication:

  • Clean the stanchions and lower legs thoroughly.
  • Ensure that the fork’s seals are properly lubricated to reduce friction and prevent noise.
