Tools Required

  • 5mm Allen wrench [paid link]
  • 6mm Allen wrench [paid link]
  • Torque wrench [paid link]
  • T25 Torx wrench [paid link]
  • Isopropyl alcohol (for cleaning)
  • Grease
  • Cable ties
  • Suspension fluid (as per manufacturer’s recommendation)
  • Fork crown race installation tool

Step-by-Step Installation Guide

  1. Preparation:
    Begin by removing your old fork from the bike, ensuring the bike is properly secured in a work stand. Clean the headset, fork steerer tube, and the head tube of the frame to ensure no debris remains. This prevents any issues during installation.
  2. Installing the Crown Race:
    The crown race should be installed on the bottom of the fork steerer tube. Use a fork crown race installation tool to ensure the crown race is seated correctly. This will prevent any unwanted noises or damage to the fork.
  3. Steerer Tube Cutting (if necessary):
    If the steerer tube is too long for your frame, measure and mark the appropriate length. Use a pipe cutter or hacksaw to carefully cut the tube. Be sure to file down any rough edges to ensure a smooth fit.
  4. Fork Installation:
    Slide the fork into the head tube of the frame. Be sure to align the fork properly with the frame to prevent any misalignment. Tighten the headset bearings using the correct torque specifications for your specific bike.
  5. Securing the Brake Mount:
    Depending on your frame, you may need to install the brake mount onto the fork. Ensure the mount is aligned properly and secure it with the appropriate bolts.
  6. Final Adjustments:
    Before tightening everything down, double-check that the fork is aligned, and the brake mounts are properly secured. Use a torque wrench [paid link] to tighten all bolts to the manufacturer’s recommended specifications.
  7. Suspension Fluid and Air Pressure:
    After installation, set the suspension fluid level in the fork according to the manufacturer’s recommendation. Adjust the air pressure based on your weight and riding style for optimal suspension performance.

Adjustment and Maintenance of the DVO Jade Fork Concept

The DVO Jade Fork Concept offers numerous adjustability features to fine-tune the fork’s performance to match your specific riding preferences. Regular maintenance ensures longevity and optimal function.

Rebound and Compression Damping Adjustments

The Jade Fork Concept features independent rebound and compression damping controls. These adjustments allow riders to dial in the fork’s performance based on trail conditions and personal preference.

  1. Compression Damping:
    Adjusting the compression damping controls the amount of resistance the fork provides during compression. A higher setting stiffens the fork, while a lower setting makes it more plush. For aggressive downhill riding, consider increasing the compression damping to provide more support.
  2. Rebound Damping:
    The rebound damping control determines how quickly the fork extends after compression. A slower rebound can help smooth out rough terrain, while a faster rebound is suitable for more aggressive riding.

Air Spring Tuning

The DVO Jade Fork Concept utilizes an air spring, which can be adjusted for air pressure. The correct air pressure should be based on your body weight, riding style, and terrain. Too much air pressure can result in a harsh ride, while too little can cause bottoming out during aggressive riding.

  1. Adjusting Air Pressure:
    Use a shock pump to adjust the air pressure. Start with the recommended air pressure for your weight, and fine-tune from there based on the trail conditions. Test the fork after adjustments to ensure it’s performing to your satisfaction.
  2. Sag Measurement:
    Set the fork sag, which is the amount of fork travel that compresses under your weight. Typically, a sag of 25-30% of total travel is ideal for most riders. Use a zip tie to mark the amount of compression on the fork stanchions, allowing for easy visual checks.

Regular Maintenance

Perform regular maintenance to keep the Jade Fork Concept operating smoothly.

  • Clean and Lubricate: Regularly clean the fork’s stanchions using isopropyl alcohol and a soft cloth to prevent dirt buildup. Lubricate the stanchions with light oil to reduce friction.
  • Check for Leaks: Inspect the fork’s seals for any signs of oil leakage. If oil is leaking, it may indicate worn seals, which should be replaced immediately.
  • Suspension Fluid Change: Over time, the suspension fluid may degrade. It is recommended to change the suspension fluid after every 100-150 hours of riding or annually, whichever comes first.

Troubleshooting Common Set-Up Issues

Despite its high-quality build, you may encounter some common issues during set-up or use of the Jade Fork Concept. Here’s how to address them.

Fork Feeling Too Stiff or Too Soft

  1. Too Stiff: If the fork feels too stiff, it could be due to excessive air pressure or compression damping settings. Adjust the air pressure by releasing some air or decreasing the compression damping. Always check the fork sag and ensure it is within the recommended range.
  2. Too Soft: If the fork bottoms out too easily, check the air pressure and adjust it higher. Also, ensure the rebound damping isn’t set too fast, which could result in poor performance on rough terrain.

Noisy Fork

  1. Sound Coming from the Stanchions: If you hear creaking or other noises from the fork, clean and lubricate the stanchions regularly. Ensure the headset is properly tightened and the fork is properly installed in the frame.
  2. Sound from the Damping System: If the damping system is making noise, it could be due to air bubbles in the fluid. Bleed the fork to remove any air from the damping system and replace any worn seals.

Loss of Travel or Sticking Suspension

  1. Loss of Travel: This may be caused by an issue with the air spring or the compression settings. Check the air pressure and ensure the correct fluid levels are maintained.
  2. Sticking Suspension: Sticking or harsh suspension action can result from debris in the stanchions or lack of lubrication. Clean the fork thoroughly and lubricate the seals. Also, check that the damper isn’t set too stiff.

Customization and Optimization for Better Performance

To get the most out of the DVO Jade Fork Concept, consider customizing the settings to your specific riding style and trail conditions. Here are some tips to optimize its performance.

Tuning for Downhill Performance

For aggressive downhill riding, increase the compression damping to provide more stability. Set the air pressure on the higher end for more support during high-impact hits. Lower the rebound damping to ensure the fork rebounds quickly enough to absorb the next bump or drop efficiently.

Tuning for Cross-Country Riding

Cross-country riders can focus on a lighter setup. Reduce the air pressure to make the fork more responsive and plush on smaller hits. Decrease the compression damping for better comfort on varied trail conditions, while keeping the rebound damping fast enough for efficient pedaling.

Comparison with Similar Models

When comparing the DVO Jade Fork Concept with other suspension forks on the market, several features set it apart.

  • DVO Jade vs. Fox 36: Both forks are high-performance options, but the Jade offers more customizable tuning with its independent rebound and compression damping adjustments. While the Fox 36 is often favored for its proven durability, the Jade offers superior adjustability and a smoother ride for different trail conditions.
  • DVO Jade vs. RockShox Pike: The Pike fork offers solid performance and reliability, but the DVO Jade stands out with its higher level of adjustability, particularly in terms of the air spring and rebound damping. For riders who prioritize fine-tuning, the Jade is the better option.

Compatibility with Other Drivetrain Components

The DVO Jade Fork Concept is designed to integrate seamlessly with most modern mountain bike drivetrains. However, there are a few key factors to keep in mind when pairing it with other components:

  1. Headset Compatibility: Ensure your bike frame is compatible with the fork’s steerer tube dimensions. The fork is available with both tapered and straight steerer tubes, so double-check compatibility with your frame’s head tube.
  2. Brake Mounts: The Jade Fork Concept comes with a post-mount brake configuration, making it compatible with a wide range of disc brakes. Be sure to verify that your brake rotors are of the appropriate size.
  3. Wheel Size: The DVO Jade Fork Concept supports various wheel sizes, including 27.5” and 29” wheels. Always ensure your frame and wheelset are compatible with the fork’s travel and axle standards.
