Key Features of the Trace36 HLR

The Trace36 HLR is built with several key features that set it apart from competitors in its category. These features provide a combination of performance, comfort, and durability for riders who want to push the limits on challenging trails.

• 36mm stanchions: The large stanchions offer added rigidity and stability, crucial for maintaining control on rough and technical terrain.
• Hydraulic Lockout (HLR): The HLR system allows riders to easily adjust the compression damping and lockout feature, offering a highly customizable experience depending on terrain conditions.
• Air spring system: It uses an air spring system that provides a responsive feel and adjustability for different rider weights and riding styles.
• Rebound adjustment: The fork is equipped with an external rebound adjustment knob, which lets riders fine-tune their rebound damping for better control.
• Boost spacing: With 110mm Boost spacing, the Trace36 HLR enhances wheel stiffness and provides a more stable ride, reducing flex during aggressive cornering.

Installation of the Trace36 HLR Fork

Installing the Trace36 HLR fork requires some mechanical skill and careful attention to detail. Here’s a step-by-step guide to get your new fork installed correctly.

1. Remove the old fork:
   • Loosen the stem bolts with the 5mm Allen wrench and remove the stem.
   • Remove the front wheel, brake caliper, and any other components attached to the fork.
   • Loosen the axle or quick release, depending on the setup, and remove the old fork from the frame.
2. Prepare the new fork:
   • Ensure the fork is in good condition and free from damage.
   • Check that the correct steerer tube length matches your bike’s frame. If needed, trim the steerer tube using a pipe cutter.
   • Apply a thin layer of bicycle grease to the steerer tube to prevent creaking and ensure smooth headset movement.
3. Install the fork into the frame:
   • Slide the Trace36 HLR into the head tube and align the fork with the headset and the frame.
   • Install the headset bearings and top cap as needed, ensuring everything is seated correctly.
4. Attach the stem and handlebars:
   • Reinstall the stem onto the steerer tube and tighten the bolts evenly, using a torque wrench [paid link] to ensure proper tension.
   • Reattach the handlebars to the stem and tighten the stem bolts in a criss-cross pattern.
5. Set the axle and front wheel:
   • Insert the axle or quick-release through the fork dropouts and secure it in place.
   • Reinstall the front wheel, ensuring it is centered properly between the fork legs.
6. Install brake calipers and hoses:
   • If necessary, install or adjust the brake caliper to fit the fork’s brake mounts.
   • Connect the brake hoses and ensure proper routing and clearance.
7. Final adjustments:
   • Check the fork alignment and make sure everything is tightened properly.
   • Set the fork to your preferred settings (air pressure, rebound, and compression damping).

Adjusting the Trace36 HLR Fork

One of the standout features of the Trace36 HLR fork is its adjustability. Adjusting the fork to your riding style and terrain can significantly improve performance. Here’s how to adjust the key settings:

Air Spring Pressure

Adjust the air spring pressure to match your weight and riding style. Typically, riders should use between 70-80 PSI for standard setups, but the air spring pressure can be adjusted to fine-tune the suspension’s response. Too much pressure will make the fork too stiff, while too little will make it too soft and prone to bottoming out.

• To adjust air pressure:
  • Use a suspension pump to add or remove air from the positive and negative air chambers.
  • Check the recommended PSI range in the user manual based on your rider weight.

Rebound Adjustment

The rebound knob on the bottom of the fork controls how quickly the fork returns to its normal position after compressing. Adjusting the rebound is crucial for maintaining control on rough terrain.

• To adjust rebound:
  • Turn the rebound knob clockwise to slow the return or counterclockwise to speed it up.
  • Start with the rebound set to medium, and then fine-tune based on ride feedback.

Compression Damping

The compression damping controls how the fork reacts to impacts. The HLR system allows for fine adjustments of low-speed compression (for rough trails) and high-speed compression (for big hits).

• To adjust compression:
  • Turn the compression knob at the top of the fork to adjust the low-speed compression.
  • For high-speed compression, use the additional high-speed knob (if equipped), found on some models of the Trace36 HLR.

Troubleshooting Common Set-Up Issues

While the Trace36 HLR is a robust and reliable fork, like any component, issues may arise. Here are some common problems and how to address them.

Fork Bottoming Out

If the fork is bottoming out too easily, it may be due to insufficient air pressure in the air spring.

• Solution: Increase the air pressure slightly (5-10 PSI) until the fork feels more responsive. Make sure to check that the rebound is properly adjusted as well.

Excessive Fork Sag

Excessive sag can occur if the air spring pressure is too low or if the fork is not properly tuned to the rider’s weight.

• Solution: Increase the air pressure and check the air chamber for leaks. Also, ensure the fork is set up according to the rider’s weight.

Noisy Suspension

Noisy suspension can be a result of dirt, insufficient lubrication, or worn-out parts.

• Solution: Clean the stanchions and lubricate them with proper suspension grease. If the noise persists, inspect the seals for wear or damage and replace them if necessary.

Customization for Better Performance

Customizing your Trace36 HLR fork can enhance its performance, making it more suitable for your specific riding style. Consider these options:

• Fork tuning: Use volume spacers to adjust the bottom-out resistance and control the fork’s ramp-up rate.
• Upgrade to a remote lockout: If you frequently ride on smoother sections, a remote lockout can make it easier to switch between different settings on the fly.
• Spring upgrades: While the air spring is versatile [paid link], some riders prefer coil springs for their consistency and smoother feel, though they require more maintenance.

Comparison with Similar Models

When compared to other forks in the same price range, such as the Fox 36 or RockShox Lyrik, the Trace36 HLR offers similar features but with a slightly different focus on adjustability. The HLR system offers fine-tuned compression damping, making it more customizable for riders who prioritize suspension performance. However, some riders may prefer the slightly smoother feel and lighter weight of the Fox 36 or RockShox Lyrik, especially on longer rides.

Compatibility with Other Drivetrain Components

The Trace36 HLR is compatible with a wide range of drivetrain systems, as it uses standard mounting options for brakes and axles. It works well with 1x and 2x drivetrains and can be easily paired with both Shimano and SRAM components. Be sure to check the brake mounting standards and axle compatibility before installation.

The large 36mm stanchions on the Trace36 HLR offer excellent stiffness, which complements modern wide rims and tires, allowing for more responsive handling in technical terrain.
