The Jade Coil [paid link] rear shock by DVO is an advanced, high-performance shock designed to offer precision and control for mountain bikers looking for top-tier suspension. Whether you are a beginner or an experienced rider, proper setup and maintenance are key to unlocking the full potential of this shock. In this guide, we will walk you through everything you need to know about installing, adjusting, maintaining, and troubleshooting your Jade Coil [paid link] shock to ensure that it performs at its best.

Tools Required

  • DVO Jade Coil shock
  • Shock pump (accurate to 1 PSI)
  • Torque wrench [paid link]
  • 2.5mm, 5mm, and 8mm hex wrenches
  • Allen key set
  • Grease
  • Cleaning supplies (rags, degreaser, etc.)

Installation of the Jade Coil Rear Shock

Installing the DVO Jade Coil shock is a straightforward process if you follow the correct steps and use the proper tools. Here’s how to do it:

  1. Remove the old shock:
    • Start by detaching your old rear shock. Use the appropriate hex wrenches to remove the bolts connecting the shock to the frame.
    • Clean the mounting areas on both the shock and the frame to ensure a smooth installation.
  2. Prepare the DVO Jade Coil:
    • Before installation, make sure that the shock is set to the correct starting settings for your weight and riding style. The spring rate should match your body weight and riding preferences. If necessary, install the appropriate spring on the shock.
    • Apply a thin layer of grease to the mounting hardware to prevent seizing over time.
  3. Mount the Shock:
    • Position the Jade Coil shock onto the frame. Ensure that the mounting hardware is aligned correctly with the shock’s eyelets.
    • Use the torque wrench [paid link] to tighten the bolts to the manufacturer’s recommended torque specification (usually around 30–35 Nm for most frames).
  4. Set Initial Sag:
    • Before riding, use a shock pump to adjust the air pressure in the shock’s main air chamber. The sag should be set at about 25-30% of the shock’s total travel. This ensures optimal performance and comfort.

Adjustment of the Jade Coil Rear Shock

Once the shock is installed, it’s time to fine-tune the settings for your specific needs. The Jade Coil offers a variety of adjustments that allow you to dial in your ride. Here’s how to adjust the key settings:

Rebound Adjustment

Rebound controls how quickly the shock returns to its original position after compressing. Proper rebound damping is crucial for maintaining control and stability.

  • To adjust, locate the rebound knob at the bottom of the shock.
  • Turn it clockwise to slow down the rebound and counterclockwise to speed it up.
  • A good starting point is to set the rebound so that it feels controlled but not too slow or fast, preventing harsh jerks or a lack of control on the trail.

Compression Adjustment

The compression adjuster controls the shock’s resistance to compressing under force. For aggressive riding, stiffer compression is recommended, while a softer setting is ideal for smoother trails.

  • The Jade Coil has a low-speed compression dial located at the top of the shock.
  • Turn clockwise to increase compression (firmer setting) or counterclockwise to decrease it (softer setting).
  • Start with the setting in the middle and adjust from there based on your riding style.

High-Speed Compression

For riders tackling rough, fast sections of trails, the high-speed compression setting is important. It helps prevent the shock from bottoming out during high-impact landings or hits.

  • The high-speed compression adjustment is a larger dial on the shock.
  • Turning it clockwise will stiffen the shock for high-speed hits, while turning it counterclockwise will make it more absorbent.

Spring Rate

The spring rate plays a significant role in determining how much support your shock provides. The Jade Coil is available with a wide range of coil springs, allowing for fine-tuned support based on your weight and riding preferences.

  • The correct spring rate can be determined by your weight. For riders weighing between 160–180 lbs, a 400-450 lb coil is typically a good starting point.
  • If you find that the shock feels too soft or too stiff during your ride, you can swap out the coil for one with a higher or lower rate.

Maintenance of the Jade Coil Rear Shock

Regular maintenance will ensure that your Jade Coil shock operates smoothly and lasts for years. Here’s how to keep it in top condition:

Clean the Shock Regularly

  • After every ride, clean the shock to remove dirt, mud, and debris. Use a soft rag and mild degreaser to gently wipe down the shock body and springs.
  • Avoid using high-pressure water to clean the shock, as it can force dirt into the seals.

Lubricate the Bushings

  • Apply a light coat of grease to the shock’s bushings to prevent wear and tear. This helps maintain smooth operation and reduces friction between the shock and the frame.

Check for Leaks

  • Periodically inspect the shock for signs of air or oil leakage, especially around the seals. If you notice any leakage, it’s time for a service.
  • A shock pump can help you check the shock’s air pressure and ensure it is holding properly.

Service the Shock

  • Over time, the internal components of your shock will wear. The Jade Coil has an air-spring system that may require servicing every 50–100 hours of riding.
  • DVO recommends having your shock serviced by a qualified technician to ensure that it is performing at its best.

Troubleshooting Common Jade Coil Issues

If you experience any issues with your Jade Coil shock, here are some common problems and how to troubleshoot them:

Too Soft or Too Stiff

  • Issue: If the shock feels too soft or too stiff, the most likely culprit is the spring rate. Make sure that you have the correct coil for your weight.
  • Solution: Swap out the coil spring for one with a higher or lower spring rate. Adjust the compression settings as well.

Rebound Too Fast or Too Slow

  • Issue: If your shock feels too bouncy or lacks control, the rebound may be incorrectly set.
  • Solution: Adjust the rebound knob to the desired speed. Start with small adjustments until you find the right setting that balances comfort and control.

Shock Bottoming Out

  • Issue: If the shock bottoms out during landings or impacts, the high-speed compression setting may be too soft.
  • Solution: Increase the high-speed compression damping to help prevent bottoming out.

Customization and Optimization for Better Performance

The DVO Jade Coil shock can be customized to suit a wide range of riding styles, from cross-country to aggressive downhill. Here are a few optimization tips:

  • Adjust the shock to your riding style: Riders who prefer a plush, comfortable ride can decrease the compression and increase the rebound damping, while aggressive riders may prefer stiffer compression settings to handle big hits.
  • Fine-tune the spring rate: Experiment with different coil springs until you find the one that provides the best balance between comfort and support.

Comparison with Similar Models

The DVO Jade Coil competes with several high-end rear shocks, such as the Fox DHX2 and the RockShox Super Deluxe Coil. While the Fox DHX2 is known for its versatility and ease of adjustment, the Jade Coil shines with its smooth, coil-sprung action and precise tuning options. The Jade Coil is also known for its durability and plush ride, making it ideal for rougher trails and more aggressive riding styles.

When compared to the RockShox Super Deluxe Coil, the Jade Coil offers a slightly more customizable setup with a broader range of adjustments, allowing riders to dial in the perfect suspension feel.

Compatibility with Other Drivetrain Components

The DVO Jade Coil is compatible with most modern mountain bike frames and drivetrains. However, it’s important to verify that your bike’s frame has the correct shock mounting dimensions (eyelet size and shock length). Additionally, while the Jade Coil pairs well with most high-end drivetrain components from Shimano, SRAM, and other brands, always check the specifications of your bike to ensure full compatibility.

By following this guide, you’ll be able to fully optimize and maintain your DVO Jade Coil shock, ensuring top-tier performance and an enhanced riding experience.
