Understanding Rear Shock Sag

Sag is the amount the rear shock compresses under the rider’s weight. It is a crucial setup step that affects the bike’s handling and comfort. For the DVO Jade Coil, the ideal sag is typically between 25% and 30% of the total shock travel. Setting the correct sag will ensure that the shock is neither too stiff nor too soft, allowing for maximum traction and shock absorption over rough terrain.

Why Sag Matters

Sag affects the overall geometry and performance of the bike. If the sag is set too low (too stiff), the shock will not compress enough to absorb bumps properly, leading to a harsh ride. If set too high (too soft), the shock may bottom out under heavy impacts, causing a loss of control. Therefore, proper sag ensures that the suspension absorbs bumps while keeping the bike stable and responsive.

Step-by-Step Guide to Setting the Sag on the DVO Jade Coil

1. Prepare Your Bike

Ensure your bike is in a stable position, preferably on a bicycle stand. The rear wheel should be off the ground to allow the shock to compress freely without interference from the floor.

2. Set the Air Pressure

Before measuring sag, use a shock pump to set the pressure in the DVO Jade Coil. The pressure should be tailored to your weight and riding style. The DVO Jade Coil does not have air springs but utilizes a coil spring, so the preload must be adjusted to fine-tune the setup.

3. Measure the Shock’s Static Sag

To measure static sag, you need a tool like a ruler or a sag measurement tool:

  • Position the bike: Sit on the bike with all your riding gear on (helmet, shoes, hydration pack, etc.) in your normal riding stance.
  • Mark the shock’s position: Measure the distance between the shock’s top-out point (the point where the shock is not compressed) and the shock’s eyelet or top collar.
  • Measure the sag: Carefully dismount, and then measure the new position of the shock’s eyelet or collar. The difference between these two measurements indicates how much the shock has sagged under your body weight.

For example, if the shock has 150mm of travel and you want 30% sag, you should aim for 45mm of sag. Adjust the preload to reach this distance.

4. Adjust the Preload

If your sag is too much or too little, you will need to adjust the preload on the coil spring. This is done by turning the preload collar on the shock:

  • Increase preload: Turn the collar clockwise to compress the spring more, which will reduce sag.
  • Decrease preload: Turn the collar counterclockwise to relax the spring and increase sag.

Make small adjustments and recheck the sag until it falls within the desired range (25% to 30%).

5. Fine-Tuning the Setup

Once you’ve set the correct sag, it’s time to fine-tune the shock for optimal performance:

  • Rebound Damping: Adjust the rebound damping to control how quickly the shock returns after compressing. For most riders, starting with a mid-range setting is ideal. Experiment by turning the rebound knob to find the setting that suits your riding style.
  • Compression Damping: If your DVO Jade Coil has compression adjustment, fine-tune the compression damping to balance the shock’s response to different terrain. A higher compression damping setting provides more support for aggressive riding, while a softer setting helps absorb small bumps more effectively.

Troubleshooting Common Issues with Sag Setup

Sag Too Soft (Bottoming Out)

If you’re experiencing bottoming out during hard impacts, your sag may be too high. In this case, increase the preload to reduce sag. This will give the shock more support and prevent it from compressing too deeply.

Sag Too Stiff (Harsh Ride)

A harsh ride typically occurs when the sag is set too low. If you feel the shock is too stiff and the ride is uncomfortable, reduce the preload to increase sag. This will allow the shock to absorb bumps more effectively, improving comfort.

Inconsistent Performance

If your bike is performing inconsistently and feels either too plush or too harsh, it could be due to incorrect rebound settings or too much/too little compression damping. Revisit your shock settings and adjust the rebound and compression until the ride feels balanced across a range of trail conditions.

Customizing and Optimizing for Better Performance

Choosing the Right Coil Spring

The DVO Jade Coil features different coil springs, each designed for a specific weight range. To further optimize the shock’s performance, make sure you select the appropriate spring based on your weight and riding style. If you ride aggressively or weigh more than average, consider using a stiffer coil to prevent excessive sag. Lighter riders may benefit from a softer coil for better small-bump sensitivity.

Upgrading the Shock

For even better performance, you can upgrade certain components of the shock. Consider adjusting the rebound and compression dampers to suit your riding style. Additionally, changing the coil to a higher-quality spring can result in a more plush ride with greater sensitivity to trail features.

Comparison with Other Models

Compared to other rear shocks in the market, the DVO Jade Coil offers several advantages, such as its adjustable rebound, compression damping, and coil spring configuration. Other models, like the RockShox Super Deluxe Coil or Fox DHX2, also use coil springs but may lack the same level of fine-tuning available with the Jade Coil.

The DVO Jade Coil stands out for its reliability and ease of setup. Riders seeking a consistent and customizable shock for aggressive trail riding or enduro racing will appreciate the Jade Coil’s performance.

Compatibility with Other Drivetrain Components

The DVO Jade Coil is compatible with most modern drivetrains, as long as the shock is correctly sized for your frame. However, it’s important to consider your bike’s geometry and the specific travel requirements of your frame. For best performance, ensure that your rear shock travel complements the front fork travel and that both are suited for your riding style.

Conclusion

Proper rear shock sag setup is essential for maximizing the performance of your DVO Jade Coil. By following these steps and making the necessary adjustments, you can achieve a balanced and comfortable ride that performs well across various trail conditions. Regular maintenance, along with troubleshooting and fine-tuning the settings, will ensure that your shock continues to deliver excellent performance throughout its lifespan.
