• Torque wrench [paid link]
• 8mm socket wrench
• Clean cloth or rag
• Suspension fluid (DVO recommended)
• Compression and rebound adjustment tool (if available)

Installation of the Jade Coil Rear Shock

Before installing your Jade Coil Rear Shock, ensure that you have the correct mounting hardware for your frame. The shock should be installed on a compatible frame designed to support coil shocks.

1. Remove the Old Shock (if applicable): Start by removing the existing shock from the bike frame. Use a 5mm Allen wrench [paid link] to unscrew the bolts securing the shock to the frame and the linkage.
2. Prepare the New Shock: Inspect the shock and ensure it is properly lubricated, especially at the mounting points. Apply grease to the hardware to prevent seizing or corrosion.
3. Install the Shock: Position the shock in place on the frame, aligning the eyelets of the shock with the mounting points on the frame. Secure the bolts in place and tighten them to the manufacturer’s recommended torque specification using a torque wrench [paid link].
4. Check Alignment: Ensure the shock is aligned correctly and that the mounting bolts are secure. Improper installation can cause the shock to misalign, leading to poor performance or potential damage.

Adjusting the Jade Coil Rear Shock

Once your Jade Coil is installed, you can fine-tune its performance through adjustments. The key adjustment points for the Jade Coil include compression, rebound, and preload.

Compression Adjustment

The compression knob on the shock allows you to control how the shock compresses under load. Adjusting the compression setting allows you to customize the shock’s performance for different terrains.

1. Turn the Compression Dial: Start with the compression dial in its default position (mid-range) and adjust according to your riding style. A more open compression setting (turning counterclockwise) is suitable for rough terrain, while a firmer setting (turning clockwise) will offer more stability on smoother tracks.
2. Test and Fine-Tune: Test ride the bike and check how the shock responds. If the shock feels too soft or too firm, adjust the compression setting in small increments until you find the optimal setting.

Rebound Adjustment

The rebound adjustment controls how quickly the shock returns to its original position after compressing. Proper rebound control is crucial for maintaining control over rough terrain.

1. Adjust the Rebound Dial: Turn the rebound dial (typically on the opposite side of the compression knob) to adjust the speed of rebound. A slower rebound (clockwise) will allow the shock to return more slowly, while a faster rebound (counterclockwise) allows the shock to return quickly.
2. Ride and Observe: Test ride the bike and observe how the shock behaves on different terrains. If the shock rebounds too quickly, it may cause the rear wheel to lose contact with the ground, resulting in a rougher ride. If the rebound is too slow, the shock might “pack down,” leading to less effective damping.

Preload Adjustment

Preload adjusts the initial spring tension to set the sag of the shock. Adjusting preload affects how much the shock compresses under the rider’s weight, which is important for proper suspension performance.

1. Adjust the Preload Ring: Use a wrench to adjust the preload ring on the coil. Turn it clockwise to increase preload and counterclockwise to reduce it. For most riders, the ideal sag is between 25-30% of the shock’s total travel.
2. Measure Sag: To ensure proper sag, sit on the bike in riding position and measure the distance the shock compresses. This will give you the correct sag and the preload adjustment required.

Maintaining the Jade Coil Rear Shock

Regular maintenance is crucial for extending the lifespan of your Jade Coil rear shock and ensuring consistent performance.

Cleaning the Shock

After each ride, clean the shock to remove dirt, mud, and debris that can cause wear over time.

1. Use a Soft Cloth: Wipe the shock body and components with a soft, clean cloth. Avoid using harsh chemicals, as they can damage the shock’s finish and seals.
2. Inspect the Shock: Check for any visible signs of damage, such as dents, cracks, or excessive wear on the seals. If any issues are found, consider servicing the shock before further riding.

Lubrication

Lubricating the shock regularly helps to maintain smooth operation and prevents corrosion.

1. Apply Suspension Fluid: Using the recommended suspension fluid, lightly lubricate the shock’s moving parts. Ensure that the air sleeve and bushings are well-lubricated to reduce friction.
2. Grease the Mounting Points: Grease the mounting hardware to ensure smooth installation and prevent seizing over time.

Regular Inspections

Inspect the shock regularly for any wear or damage. Check the coil spring, the damper, and the seals. If the shock feels overly soft or hard, or if it makes unusual noises, it might be time to service it.

Troubleshooting Common Jade Coil Rear Shock Issues

Understanding and addressing common issues with your Jade Coil rear shock can prevent problems from affecting your riding experience.

Loss of Air Pressure

If the shock feels softer than usual or has a sag beyond the normal setting, it could indicate a loss of air pressure in the air chamber.

1. Check for Leaks: Inspect the shock for any visible signs of air leakage, such as a greasy residue around the seals.
2. Reinflate the Shock: Use a shock pump to restore the proper air pressure. If the problem persists, inspect the seals and consider servicing the shock.

Unresponsive or Bouncy Shock

If the shock feels too soft and bouncy, it could be due to improper compression or rebound settings.

1. Adjust Compression and Rebound: Recheck your compression and rebound settings. Increase compression for firmer performance and adjust the rebound to ensure proper damping.
2. Inspect the Coil: Check the coil for any signs of damage or sag. A coil that has lost its tension will need to be replaced.

Noisy Shock

A noisy shock could indicate worn seals or improper lubrication.

1. Lubricate Moving Parts: Ensure that the moving parts of the shock are adequately lubricated.
2. Check the Seals: Inspect the seals for damage or wear. If damaged, the seals may need to be replaced.

Customizing Your Jade Coil Rear Shock for Optimal Performance

Customizing your Jade Coil shock for your specific riding style can significantly enhance your bike’s performance.

1. Fine-Tune Adjustments: Experiment with different compression, rebound, and preload settings to match your riding style. A more aggressive rider may prefer stiffer settings, while a smoother rider might benefit from a more plush shock feel.
2. Spring Rate: If you’re experiencing bottoming out or insufficient compression, you might need a stiffer spring. Consult with a bike shop to select the right spring rate based on your weight and riding conditions.
3. Upgrade Options: DVO offers several upgrade options, such as custom springs or a higher-end damper. These options can further optimize your ride for different terrain types, including downhill or cross-country.

Compatibility with Other Drivetrain Components

The Jade Coil rear shock is designed to be compatible with most modern mountain bike frames and drivetrain components. However, compatibility with the rest of your bike’s drivetrain should be considered when choosing the shock.

1. Frame Compatibility: Ensure that your frame has the correct mounting points for a coil shock. Some frames may only support air shocks, while others are designed to work specifically with coil shocks.
2. Suspension Geometry: The geometry of your frame and suspension system will affect how the shock performs. If you’re unsure, consult the frame manufacturer or your local bike shop to ensure compatibility.
3. Shock Length and Stroke: The length and stroke of your Jade Coil rear shock must match the specifications of your frame for optimal performance. Check your frame’s specifications before purchasing or swapping shocks.

Conclusion

The Jade Coil Rear Shock from DVO is a high-performance suspension component that, when maintained and adjusted properly, can significantly enhance your riding experience. Regular cleaning, lubrication, and appropriate adjustments will ensure long-lasting performance, while troubleshooting common issues can help you address problems before they affect your ride. Customizing the shock to fit your specific needs and ensuring compatibility with your bike frame will result in a smoother, more responsive suspension system that can handle a variety of terrains with ease.
