  • 8mm and 10mm Allen wrenches [paid link]
  • 12mm socket wrench
  • Torque wrench [paid link] (for precise adjustments)
  • Degreaser and soft cloth
  • Suspension oil (RockShox recommended)

  • A clean workbench or bike stand [paid link]
  • 3mm and 5mm Allen wrenches [paid link] (for small adjustments)

Installation of the Vivid Ultimate Rear Shock

Installing the RockShox Vivid Ultimate Rear Shock correctly is crucial for both safety and performance. Follow these steps for proper installation:

  1. Prepare the Rear Triangle: Before removing your old shock, ensure that the rear triangle of your bike is clean and free from dirt or debris.
  2. Remove the Old Shock: Using an 8mm or 10mm Allen wrench [paid link], remove the bolts securing the shock to the frame. Keep these bolts in a safe place if you plan to re-use them.
  3. Align the Vivid Ultimate Rear Shock: Align the Vivid Ultimate shock with the mounting holes on your bike’s rear triangle. Double-check the position and ensure the shock is facing the right direction (with the air valve accessible).
  4. Install the Shock: Insert the shock into place and secure it with the mounting bolts. Tighten them gradually to ensure an even fit.
  5. Torque Settings: Using a torque wrench [paid link], tighten the bolts to the manufacturer-recommended torque settings to avoid over-tightening, which can damage the shock or frame.
  6. Recheck Alignment: Ensure that the shock is properly aligned in both the mounting points to avoid unnecessary stress on the shock and frame.

Adjustment of the Vivid Ultimate Rear Shock

Once installed, fine-tuning your Vivid Ultimate is essential for achieving the best ride quality. Adjustments can be made to accommodate different riding styles and terrain types. Here’s how to adjust your shock:

Air Spring Pressure

  1. Determine Rider Weight: Use the recommended air pressure chart provided by RockShox based on your body weight. This will give you a good starting point.
  2. Use a Shock Pump: Attach your shock pump to the air valve on the Vivid Ultimate. Pressurize the shock according to your weight and riding style. For trail riders, aim for around 25-30% of the total shock travel as sag.
  3. Check for Sag: After adjusting, sit on the bike and check the sag. If the shock feels too firm, reduce the air pressure. If it’s too soft, increase the air pressure until you achieve the desired sag.

Rebound and Compression Damping

  1. Adjust Rebound: The rebound adjustment controls how quickly the shock returns to its original position after compression. Turn the rebound knob located at the base of the shock (usually counterclockwise to speed it up, clockwise to slow it down). Start by setting it in the middle and adjust based on your preference and terrain.
  2. Adjust Compression: The compression damping controls how the shock behaves when hitting bumps or impacts. The Vivid Ultimate has low-speed and high-speed compression settings. Adjust the low-speed compression knob for general riding conditions. For more aggressive terrain or downhill riding, increase the high-speed compression.
  3. Fine-tune: Test ride the bike after each adjustment to determine the effect of your changes. Make small adjustments to find the optimal setting for your riding style.

Maintenance of the Vivid Ultimate Rear Shock

Regular maintenance of the RockShox Vivid Ultimate is necessary to extend its lifespan and maintain its performance. Follow these steps to keep your shock in top shape:

Cleaning and Inspection

  1. Clean the Shock: After each ride, clean the shock with a soft cloth and mild degreaser. Be sure to remove dirt, dust, or mud that may have accumulated during your ride.
  2. Check for Leaks: Inspect the shock for any oil leaks around the seals or the body. If you notice any signs of leakage, it’s time for a service.

Lubrication

  1. Lubricate the Bushings: Apply a thin layer of grease to the shock’s bushings every few months to reduce friction and ensure smooth movement.
  2. Suspension Oil: If you notice a decrease in performance or a rough feeling when riding, it may be time to replace the suspension oil. Follow the manufacturer’s guidelines for the recommended oil type and volume.

Service Intervals

  1. Air Sleeve Service: Every 50-100 hours of riding, it’s recommended to service the air sleeve. This involves removing the shock’s air sleeve and cleaning it thoroughly. Apply fresh lubrication to the seals and reinstall the sleeve.
  2. Full Overhaul: After about 200-300 hours of use, or if the shock performance diminishes significantly, consider a full overhaul. This involves draining and replacing the shock oil and replacing the internal seals.

Troubleshooting Common Issues

Here are some common problems you might encounter with your Vivid Ultimate Rear Shock, along with solutions:

Shock Bottoming Out

  • Problem: The shock bottoms out too frequently, indicating it’s not absorbing impacts properly.
  • Solution: Increase air pressure to reduce bottoming out. Check the compression settings and adjust for a firmer feel if necessary. Additionally, ensure that your riding sag is within the recommended range.

Lack of Rebound Control

  • Problem: The shock rebounds too quickly or too slowly.
  • Solution: Adjust the rebound setting to fine-tune the return speed. If the problem persists, the shock might need servicing, as worn-out seals can affect rebound performance.

Loss of Air Pressure

  • Problem: The shock loses air pressure after a few rides.
  • Solution: Inspect the air valve and surrounding seals for leaks. If you find any issues, replace the seals and check the valve for damage.

Customization and Optimization for Better Performance

The Vivid Ultimate is designed for customization, allowing riders to fine-tune their suspension to match their preferences. Here are some tips to further optimize the shock:

  1. Adjust for Terrain: For downhill or aggressive riders, increasing high-speed compression damping can provide better support when landing jumps or hitting rough sections of trail.
  2. Use a Custom Tune: If you’re a competitive rider, consider having your shock custom-tuned by a professional. Custom tuning adjusts the damper settings for your specific riding style, providing a more personalized feel.
  3. Upgrade to a Coil Spring: If you’re looking for a more plush ride and additional control, consider upgrading to a coil spring instead of the air spring option. The coil offers more consistent performance, especially on bigger hits and rougher trails.

Comparison with Similar Models

When comparing the RockShox Vivid Ultimate to other rear shocks like the Fox DHX2 or Marzocchi Bomber CR, there are a few key differences to consider:

  • Customization: The Vivid Ultimate provides more extensive adjustability with separate low-speed and high-speed compression, allowing for more precise tuning for different terrains.
  • Weight: The Vivid Ultimate is slightly heavier than other models like the Fox DHX2, making it less ideal for lightweight race setups.
  • Durability: The Vivid Ultimate is renowned for its robust build and longevity, especially in harsh conditions, making it a go-to for downhill riders who demand a durable shock.

Compatibility with Other Drivetrain Components

The RockShox Vivid Ultimate Rear Shock is compatible with most modern downhill and enduro frames. When integrating it with your bike’s drivetrain, ensure that the shock’s length and stroke match your frame’s specifications. Additionally, the shock’s air pressure and compression settings can be adjusted to work with various suspension forks for a balanced and optimized ride.
