The DVO Jade Coil [paid link] rear shock is designed for exceptional performance, providing superior damping, reliability, and adjustability for riders seeking the best in suspension technology. However, like any high-performance component, it can encounter some issues over time. In this article, we will address common problems riders may face with the Jade Coil [paid link] rear shock and provide solutions for troubleshooting and maintaining the shock to ensure optimal performance.
Common Issues with the DVO Jade Coil Rear Shock
1. Shock Sag Issues
Sag refers to how much the shock compresses under the rider’s weight. Having the correct amount of sag is crucial for maximizing the performance of the shock.
Cause:
Incorrect sag can occur if the spring rate is not properly matched to the rider’s weight, or if the shock has not been set up correctly.
Solution:
- Adjust the Spring Rate: If you notice excessive sag or insufficient sag, consider switching to a spring that matches your weight. DVO offers various spring rates for the Jade Coil to accommodate different rider weights.
- Set Correct Sag: To properly set the sag, ensure the shock is set to around 25-30% of total travel. Use the proper measurement technique (fully extended shock, compress the shock to your weight, and measure the distance of compression).
- Check for Wear: Inspect the shock’s bushings and the shock mount area. If these components are worn, they could affect the performance and contribute to sag problems.
2. Excessive Rebound
Excessive rebound occurs when the shock extends too quickly after compression, leading to a bouncy, uncomfortable ride.
Cause:
This issue is usually caused by the rebound damping setting being too fast, meaning the shock does not absorb the energy during the rebound stroke.
Solution:
- Adjust the Rebound Damping: The Jade Coil rear shock features a rebound adjuster that allows for precise tuning of the shock’s return speed. Turn the rebound knob clockwise to slow the rebound or counterclockwise to speed it up.
- Inspect for Oil Leaks: If adjustment doesn’t seem to resolve the issue, inspect the shock for oil leaks. A loss of oil can lead to inadequate damping, causing the rebound to behave erratically.
- Check the Shock’s Condition: If the issue persists despite adjustment, consider having the shock serviced. Internal components like the damper can wear out over time, impacting its performance.
3. Shock Bottoming Out
Bottoming out occurs when the shock reaches the end of its travel during heavy impacts, often resulting in a harsh, jarring experience for the rider.
Cause:
This can be caused by too soft of a spring rate, excessive rebound damping, or an incorrect compression setting.
Solution:
- Check the Spring Rate: Ensure the spring rate is appropriate for your weight. If you are consistently bottoming out, a stiffer spring may be necessary to prevent full travel compression.
- Adjust Compression Damping: DVO’s Jade Coil shock comes with an adjustable compression damping dial. To prevent bottoming out, adjust the compression damping to a firmer setting, particularly on the low-speed compression dial.
- Fine-Tune the Rebound: An overly fast rebound setting can contribute to bottoming out. Adjusting the rebound damping can help mitigate this issue.
4. Excessive Stiction or Stickiness
Stiction occurs when the shock feels sluggish or sticky during compression and rebound. This can lead to poor small bump sensitivity and an overall compromised suspension feel.
Cause:
Excessive friction within the shock can be due to improper lubrication, contamination, or wear on the shock’s seals and bushings.
Solution:
- Inspect for Dirt or Contamination: Clean the shock’s seals and ensure they are free from dirt or debris. Contaminants can cause the seals to drag, leading to stiction.
- Re-lubricate the Shock: Apply the recommended lubricant to the shock’s seals and bushings to reduce friction. Ensure proper maintenance and lubrication at regular intervals to maintain smooth performance.
- Replace Worn Seals: If lubrication doesn’t resolve the issue, inspect the seals for wear. Replacing worn seals can eliminate stiction and restore smooth shock action.
5. Air in the Shock or Inconsistent Performance
Air bubbles or incorrect air pressure inside the shock can cause inconsistent performance and poor damping behavior.
Cause:
Over time, air can mix with the oil inside the shock, leading to inconsistent damping and poor responsiveness. This is often due to improper maintenance or an issue with the shock’s internal bladder system.
Solution:
- Service the Shock: If you suspect air is present in the shock, it is essential to have the shock serviced by a professional. DVO recommends regular maintenance to ensure the shock remains free of air bubbles and operates smoothly.
- Check for Leaks: Inspect the shock for any signs of air or oil leakage. Leaks may allow air to enter the system, causing performance inconsistencies.
6. Noise from the Shock
Strange noises such as squeaks, clicks, or knocking sounds can be distracting and indicate potential issues with the shock.
Cause:
Noise can be caused by a variety of factors, such as improperly lubricated bushings, loose hardware, or worn-out seals.
Solution:
- Inspect the Bushings and Mounts: Ensure the shock’s mounting hardware is properly torqued and that there is no play in the shock’s bushings or mounts.
- Lubricate Moving Parts: Apply lubricant to the shock’s bushings and any moving parts to reduce noise from friction.
- Tighten Loose Bolts: Check that all bolts and screws securing the shock to the frame are tight and properly torqued to avoid rattling or knocking sounds.
Conclusion
The DVO Jade Coil rear shock is a premium suspension component designed for performance, but like any mechanical system, it can experience issues over time. By understanding common problems and their solutions, you can ensure that your shock remains in optimal working condition for the best possible ride. Regular maintenance, proper setup, and timely servicing are key to extending the life of your Jade Coil and keeping it performing at its peak [paid link].
