• 5mm Allen wrench [paid link]
• 8mm Allen wrench [paid link]
• Shock pump
• Grease or anti-seize compound
• Rags for cleaning

Step-by-Step Installation

1. Prepare the Bike Frame: Ensure that the frame is clean and free from dirt or debris around the rear shock mounting points. A clean surface will prevent any contamination during installation.
2. Attach the Shock to the Frame: Begin by placing the DVO Jade Coil shock into the frame’s shock mount. Make sure the shock’s eyelets align properly with the mount points.
3. Insert the Mounting Bolts: Insert the mounting bolts through the shock’s eyelets and tighten them using an 8mm or 10mm socket wrench. Ensure the bolts are installed properly and tighten them to the manufacturer’s specified torque setting, typically between 175-200 in-lb.
4. Install the Coil Spring: If the coil spring is not pre-installed, carefully insert it over the shock body, ensuring that it sits securely in the spring seat. Pay attention to the compression setting as you install the coil.
5. Set the Sag: Use a shock pump to adjust the pressure. The Jade Coil’s air spring can be set for different rider weights and preferences. Refer to the recommended sag settings for your weight and riding style, typically around 30-35% of the total shock stroke length.
6. Final Tightening: Once everything is in place, perform a final check and ensure all bolts are torqued to the correct specifications.
7. Test the Shock: Before riding, gently compress the rear suspension to make sure it moves smoothly. Ensure there are no issues with shock movement or noise.

Adjusting the Jade Coil Rear Shock

The DVO Jade Coil rear shock features multiple adjustments to customize the ride to your preferences. Understanding these adjustments can significantly enhance the performance and feel of your bike.

Rebound Damping Adjustment

The rebound damping controls how quickly the shock returns after compression. This adjustment is crucial for maintaining control, especially during aggressive descents.

• To adjust rebound: Turn the rebound knob located at the bottom of the shock. Clockwise for slower rebound and counterclockwise for faster rebound. Start with the recommended baseline setting and fine-tune based on your riding style and terrain.

Compression Damping

Compression damping controls the shock’s resistance during compression. It helps you control the shock’s performance under heavy impacts or during rough descents.

• To adjust compression: The compression knob is typically located on the top of the shock. Turning it clockwise increases compression, while counterclockwise reduces it. You can adjust it based on how firm or plush you want the shock to feel.

Spring Tuning

The Jade Coil rear shock allows for coil spring replacement based on your weight and riding style. Choosing the right spring rate ensures that the shock performs at its best, offering both comfort and control.

• Choosing the correct coil spring: DVO provides a range of spring rates to match different rider weights. A heavier rider will require a stiffer spring, while a lighter rider may need a softer one. Consult the manufacturer’s guidelines for recommended spring rates based on your weight.

Maintenance of the Jade Coil Rear Shock

Regular maintenance ensures that your DVO Jade Coil rear shock continues to perform at a high level for years to come.

Cleaning the Shock

1. Use a soft cloth to wipe off any dirt or grime from the shock after each ride.
2. Avoid using harsh chemicals or solvents that can damage the shock’s seals.

Checking the Air Pressure

The Jade Coil features an air spring that needs periodic checks to ensure the correct pressure. Always use a shock pump to avoid over- or under-inflation, which can lead to poor suspension performance.

Servicing the Shock

DVO recommends servicing the Jade Coil rear shock annually or every 50-100 riding hours. This service involves replacing the seals, cleaning the internal components, and checking for wear. You can perform basic maintenance yourself, but for more comprehensive servicing, it’s best to have a professional mechanic do the work.

Lubricating the Shock

Lubrication of the shock is important for maintaining smooth operation. Apply grease to the shock’s mounting bolts and any moving parts, such as the spring seat, to reduce friction and wear.

Troubleshooting Common Issues with the Jade Coil Rear Shock

Despite its robust design, the Jade Coil rear shock can encounter issues during use. Here’s how to identify and resolve common problems.

Sag Issues

If you’re experiencing too much sag or not enough, it may be due to incorrect air pressure or an improper spring rate. Recheck your air pressure and ensure that the spring rate matches your weight and riding style.

• Too much sag: This could be due to a spring that’s too soft or too much air pressure in the shock.
• Not enough sag: The spring rate might be too firm, or the shock might not be set to the correct air pressure.

Poor Rebound or Compression Performance

If the rebound feels too fast or slow, or if the compression settings are ineffective, it may be due to incorrect tuning or internal issues with the shock’s damping circuits. Revisit the rebound and compression adjustments and fine-tune based on your preferences.

Noisy Shock

If the shock is making a knocking or creaking sound, it might indicate issues with the mounting bolts or spring. Tighten all bolts and check for any loose components.

Customization and Optimization for Better Performance

To get the most out of the Jade Coil rear shock, fine-tuning is essential. Here’s how to optimize the shock for your riding style.

• Weight and Spring Rate: Ensure the spring rate matches your body weight. DVO offers a wide range of spring rates, so choose the one that provides the right amount of support and comfort.
• Rebound and Compression Settings: Adjust the rebound and compression settings based on the terrain you ride. Faster rebound settings are beneficial for rocky trails, while slower settings are useful for smoother trails.
• Sag and Air Pressure: Set your sag correctly to optimize the shock’s travel and performance. Check the air pressure regularly to ensure consistent performance.

Comparison with Similar Models

When compared to other rear shocks in the market, such as the RockShox Super Deluxe Coil or the Fox DHX2, the DVO Jade Coil stands out for its superior adjustability and build quality. Here’s a comparison of the key features:

• Adjustability: The Jade Coil offers more fine-tuned adjustment capabilities than many competing models, giving riders more control over their suspension setup.
• Spring Options: Unlike many models that offer limited spring rates, the DVO Jade Coil has a broad selection to cater to a variety of rider weights and preferences.
• Price and Performance: The Jade Coil is competitively priced while offering top-tier performance, making it an excellent choice for riders looking for a high-quality shock without breaking the bank.

Compatibility with Other Drivetrain Components

The DVO Jade Coil rear shock is designed to work seamlessly with most modern mountain bike drivetrain systems. However, it’s important to ensure that your bike’s frame can accommodate a coil shock, as not all frames are compatible with this type of shock.

• Bike Frames: The shock is typically compatible with bikes that have the necessary mounting points for a coil shock. Make sure your bike’s rear suspension is designed for the type of shock you are installing.
• Drivetrain Compatibility: The Jade Coil doesn’t directly affect your drivetrain’s compatibility but does impact overall ride performance. If you’re upgrading your suspension, it’s a good idea to consider how the rear shock will work with your other components to maintain balanced performance.
