The Jade X Coil [paid link] Rear Shock from DVO is a high-performance suspension component designed to offer exceptional control, comfort, and durability for riders who demand the best from their bike. This guide will walk you through the process of installing, adjusting, maintaining, and troubleshooting the Jade X Coil [paid link], ensuring you can optimize its performance for your riding style. Additionally, we’ll discuss its compatibility with other drivetrain components and compare it to similar models to help you make an informed decision.

Tools Required

• 5mm Allen wrench [paid link]
• 10mm wrench (for mounting bolts)
• Torque wrench [paid link] (set to manufacturer’s specifications)
• Shock pump (for air spring adjustments)
• Grease (preferably suspension grease)
• Rags or cleaning materials
• Oil (for servicing the shock, as specified by the manufacturer)
• Bushing press (if you need to replace the shock bushings)

Installing the Jade X Coil Rear Shock

Installing the Jade X Coil is a straightforward process, but it requires careful attention to ensure optimal performance and avoid any damage to the frame or shock. Here’s how to install it properly:

1. Remove the Existing Shock:
   • Use a 5mm Allen wrench [paid link] to remove the bolts securing the old shock to the frame. Make sure to keep the bolts as you will use them for the new shock installation.
2. Prepare the Jade X Coil:
   • Ensure the Jade X Coil rear shock is properly greased on the mounting points. Apply a light coat of suspension grease to the bushings to reduce wear over time.
3. Mount the Shock:
   • Place the shock into the mounting area, aligning the bushings with the frame’s shock mounts. Use the bolts from the old shock to secure the new coil shock in place.
   • Tighten the bolts to the specified torque setting provided in the DVO user manual (typically around 20-25Nm).
4. Adjust the Air Pressure and Rebound Settings:
   • Set the appropriate air pressure in the shock using a shock pump, depending on your rider weight and the terrain you’re riding.
   • Adjust the rebound setting to match your preferences for comfort and performance.
5. Final Check:
   • Double-check all bolts to ensure they are tight and secure. Perform a quick suspension test by gently compressing the shock to verify smooth movement.

Adjusting the Jade X Coil Rear Shock

The Jade X Coil Rear Shock comes with several adjustable features that allow you to fine-tune the suspension to match your riding style and preferences. Here’s a breakdown of the key adjustments:

Preload Adjustment:

The preload setting on the Jade X Coil is crucial for achieving the correct sag and initial compression. Preload adjusts the initial tension on the spring, allowing you to control how the shock responds to your body weight.

• Use the preload adjustment collar to fine-tune the amount of preload on the spring. A stiffer preload is recommended for heavier riders or more aggressive riding, while a lighter preload suits lighter riders or more technical terrains.
• Make adjustments incrementally, checking the sag after each adjustment. Aim for about 25-30% of your total shock stroke to be used when sitting on the bike.

Rebound Adjustment:

Rebound damping controls the speed at which the shock returns to its original position after compression. It’s essential for maintaining control and stability during fast descents or rough terrain.

• Turn the rebound knob clockwise for slower rebound (better for high-speed control) or counterclockwise for faster rebound (better for small bumps and technical sections).
• Always make small adjustments and test the bike on different terrains to find the ideal setting.

Compression Adjustment:

The compression adjustment allows you to fine-tune how the shock compresses when hitting bumps or obstacles. This setting impacts the shock’s ability to absorb impacts, providing a more controlled and smooth ride.

• Adjust the low-speed compression for overall ride feel—higher settings make the shock more resistant to compression, ideal for aggressive riding or big hits.
• High-speed compression affects how the shock responds to faster, more aggressive impacts. Adjust this to prevent the shock from bottoming out on large drops or hits.

Maintaining the Jade X Coil Rear Shock

Proper maintenance of your Jade X Coil Rear Shock will prolong its lifespan and keep it performing at its peak [paid link]. Here are the key maintenance steps:

Routine Cleaning:

• After every ride, clean the shock with a soft cloth and warm water to remove dirt and debris. Avoid using harsh chemicals, as they can damage the shock’s seals and finish.
• Check the shock for any signs of oil leakage, which may indicate a seal issue.

Servicing the Shock:

• It’s recommended to service the shock every 50-100 hours of riding, depending on how often you ride and the conditions. This includes changing the oil and inspecting internal components.
• If you’re not experienced with servicing shocks, it’s best to take the shock to a professional mechanic or the manufacturer’s service center.

Spring and Bushings:

• Periodically check the spring for any signs of wear or damage. If necessary, replace the spring to match your changing riding style or body weight.
• Check the bushings for wear. If the shock feels sluggish or makes noise during travel, it may be time to replace the bushings using a bushing press.

Troubleshooting Common Issues

While the Jade X Coil is a durable and reliable component, certain issues may arise during use. Here’s how to troubleshoot common problems:

1. Sag Issues:

• Problem: The bike feels too soft or too stiff, with improper sag.
• Solution: Adjust the preload to ensure proper sag. If the shock feels too soft, add more preload. If it feels too stiff, reduce the preload.

2. Rebound Problems:

• Problem: The shock is too slow or too fast on rebound.
• Solution: Adjust the rebound knob as needed. Too slow a rebound can cause the bike to feel sluggish, while too fast can make it bouncy.

3. Noisy Shock:

• Problem: The shock makes a knocking or squeaking noise.
• Solution: Check the mounting bolts to ensure they are tight. Inspect the bushings for wear, and replace them if necessary.

4. Bottoming Out:

• Problem: The shock bottoms out on large impacts or drops.
• Solution: Adjust the compression settings or consider switching to a stiffer spring if you are riding more aggressive trails.

Customization and Optimization

To get the best performance out of your Jade X Coil, consider customizing it based on your specific riding style and the terrain you frequent. Here’s how:

• Spring Rate: DVO offers various spring rates for the Jade X Coil. If you plan on riding aggressive terrain or you’re a heavier rider, opt for a firmer spring. Lighter riders or those who stick to smoother trails may prefer a softer spring.
• Shock Length and Stroke: Ensure your shock’s length and stroke match your bike’s frame. The Jade X Coil is versatile [paid link], but it’s important to select the right size for your bike.
• Damping Adjustments: Fine-tune your compression and rebound settings to match your riding style. Riders who frequently tackle downhill courses should prioritize slow rebound and firm compression.

Comparing the Jade X Coil Rear Shock

When comparing the Jade X Coil to other rear shocks in the market, especially within the same price range, here’s how it stacks up:

• DVO Jade X vs. Fox DHX2: Both shocks offer high-end performance, but the Jade X is typically seen as more adjustable with a smoother, more plush feel at lower speeds. The DHX2, on the other hand, tends to have a more responsive compression circuit, ideal for aggressive riders.
• DVO Jade X vs. RockShox Super Deluxe Coil: While both shocks offer similar adjustability, the Jade X has a more forgiving compression curve, making it better for technical and steep descents. The RockShox is slightly stiffer, which may appeal to riders who need more support on faster terrain.

Compatibility with Other Drivetrain Components

The Jade X Coil is designed to work seamlessly with most modern mountain bike drivetrains, including both Shimano and SRAM systems. It’s crucial to ensure your bike frame can accommodate the shock’s eyelet size and stroke length, as using an incompatible shock can affect suspension performance and potentially damage the frame. Always refer to your bike manufacturer’s specifications before installation.
