  • 10mm socket wrench
  • Shock pump
  • 2.5mm Allen wrench [paid link]
  • Torque wrench [paid link]
  • 15mm spanner wrench
  • Small oil pan or container
  • Isopropyl alcohol (for cleaning)
  • Rags or paper towels
  • DVO Topaz 2.0 oil (specified for the model)
  • Needle-nose pliers (optional)
  • Plastic syringe (optional)

Preparation

Before beginning the oil change, ensure that you have a clean, organized workspace where you can comfortably work on your Topaz 2.0 shock. You will need to remove the shock from the bike frame, which will require careful handling to prevent any damage to the components. Be sure to check the shock’s pressure and relieve it completely before starting the oil change.

Step 1: Removing the Shock from the Bike

  1. Use the 8mm Allen wrench to remove the bolts securing the shock to the frame of your bike. Carefully slide the shock out, making sure not to damage any parts during the process.
  2. Ensure that you don’t lose any small parts, such as washers or spacers, during the removal.

Step 2: Disassembling the Shock

  1. Remove the air sleeve: Use the 10mm socket wrench to remove the bolt securing the air sleeve to the shock body. You may need to gently pry off the air sleeve if it’s stuck, but avoid using excessive force to prevent damaging the components.
  2. Loosen the shock body: Using the 15mm spanner wrench, carefully loosen the shock body from the shaft. This may require a gentle rocking motion to break the seal.

Step 3: Draining the Old Oil

  1. Position the shock over an oil pan to catch the old oil. Hold the shock upright and ensure that the air sleeve and shock body are separated so that the oil can drain completely.
  2. Allow the oil to drain: Give it some time to drain out, ensuring that all old oil is removed. This process may take a few minutes depending on the shock’s design and the oil used.

Step 4: Cleaning the Components

  1. Clean the shock body and air sleeve: Use isopropyl alcohol and rags or paper towels to thoroughly clean all components, including the air sleeve, shock body, and shock shaft. Be sure to remove any dirt, debris, or old oil from the shock.
  2. Inspect seals and parts: Check all seals, o-rings, and washers for any signs of wear or damage. If any parts appear worn out or damaged, replace them immediately to ensure the shock functions properly.

Step 5: Refilling with New Oil

  1. Prepare the new oil: Use the DVO Topaz 2.0 oil that is specifically recommended for your shock model. Pour the appropriate amount of oil into a clean container or syringe, as specified in your shock’s maintenance manual.
  2. Fill the shock body: Using the syringe, slowly fill the shock body with the new oil. Be cautious to avoid overfilling. You want to fill the body to the appropriate level as indicated in the manual to ensure proper function.
  3. Reinstall the air sleeve: Carefully slide the air sleeve back onto the shock body. Ensure that it is seated correctly and is fully engaged.

Step 6: Reassembling the Shock

  1. Tighten the shock body: Using the 15mm spanner wrench, securely tighten the shock body back into place. Ensure that the assembly is tight, but do not over-tighten, as this could cause damage.
  2. Secure the air sleeve: Reattach the air sleeve by securing the 10mm bolt with the socket wrench. Again, tighten securely but avoid over-tightening.

Step 7: Reinstalling the Shock on the Bike

  1. Reattach the shock to the frame: Carefully align the shock with the frame and use the 8mm Allen wrench to reattach the shock. Make sure the bolts are tightened to the recommended torque specification to prevent any movement during riding.
  2. Check the alignment: Ensure that the shock is aligned correctly and that it sits firmly in place without any play.

Step 8: Recharging the Air Pressure

  1. Use a shock pump to reintroduce the appropriate air pressure into the shock according to your weight and riding style. This step is crucial as it affects both the performance and comfort of the shock.
  2. Double-check the air pressure after installing the shock back onto the bike to ensure it matches your setup requirements.

Troubleshooting Common Issues

While performing an oil change, you may encounter a few issues. Here are common troubleshooting tips:

  • Leaking oil: If oil leaks from the seals after an oil change, it is likely that the seals were not properly installed or there is damage to the o-rings. Inspect all seals closely and replace them if needed.
  • Shock feels too soft or stiff: This could be due to incorrect air pressure or insufficient oil. Ensure that both the oil level and air pressure are set to the manufacturer’s recommendations.
  • Air sleeve not fitting: If the air sleeve does not slide easily onto the shock body, check for any debris or old oil residue that may be causing a blockage. Clean the surfaces thoroughly before reassembly.

Customization and Optimization

To optimize the performance of your Topaz 2.0 shock, consider making the following adjustments after performing an oil change:

  • Tuning the compression and rebound settings: The Topaz 2.0 allows for precise adjustments to both the compression and rebound damping. Fine-tune these settings to match your riding style and terrain.
  • Adjusting air pressure for different conditions: By adjusting the air pressure, you can fine-tune the shock’s responsiveness. Lower pressure can provide more sensitivity for technical terrain, while higher pressure can improve stability for rougher trails.

Comparison with Similar Models

The DVO Topaz 2.0 Limited Edition is known for its advanced damping system and customizable features, setting it apart from many other rear shocks in its class. When compared to models like the Fox Float X2 or RockShox Super Deluxe, the Topaz 2.0 offers a slightly more responsive compression and rebound damping system, making it ideal for riders looking for fine-tuned suspension performance. Additionally, the Topaz 2.0’s oil change process is more straightforward, which can be a significant advantage for riders who want to maintain their shock themselves.

Compatibility with Other Drivetrain Components

The DVO Topaz 2.0 Limited Edition rear shock is designed to work seamlessly with a variety of high-performance drivetrains. It’s particularly well-suited for use with the latest 12-speed systems from brands like Shimano and SRAM. Ensure that the shock’s geometry and travel are compatible with your bike’s frame and other suspension components for optimal performance.
