Installation of the Deluxe Coil Ultimate Rear Shock

Proper installation of the RockShox Deluxe Coil Ultimate is essential for optimal performance. Here’s how to do it step by step:

Tools Required:

• Torque wrench [paid link]
• 5mm Allen key
• 8mm Allen key
• Shock pump (for air pressure)
• Grease
• Rags for cleaning

Installation Steps:

1. Remove the Old Shock: If replacing an existing shock, begin by removing the current rear shock from the frame. Use the appropriate Allen key sizes to loosen the mounting bolts.
2. Prepare the New Shock: Unbox your Deluxe Coil Ultimate and inspect it for any damage. Apply a small amount of grease to the shock mounting points to ensure smooth installation and prevent creaking.
3. Install the Upper Mount: Position the shock so that the upper mounting eyelet aligns with the shock mount on the frame. Insert the bolt and tighten it to the manufacturer’s recommended torque setting.
4. Install the Lower Mount: Similarly, align the lower mounting eyelet with the frame’s shock mount. Insert the bolt and tighten to the specified torque.
5. Set Rebound and Compression: Adjust the rebound and compression settings based on your personal preferences before riding.
6. Test for Clearance and Performance: Check the shock clearance and suspension travel to ensure there are no issues. Perform a basic test ride to assess the shock’s performance.

Adjusting the Deluxe Coil Ultimate Rear Shock

Fine-tuning the Deluxe Coil Ultimate rear shock is key to achieving the best possible performance for your specific needs. Follow these guidelines for adjustments:

Rebound Adjustment:

• Rebound Speed: The rebound dial located on the bottom of the shock allows you to adjust the speed at which the shock extends after compression. A slower rebound is ideal for rough, fast trails, while a faster rebound is suitable for smoother, less aggressive terrain.
• How to Adjust: Turn the rebound knob clockwise to slow the rebound and counterclockwise to increase it. Start with the middle setting and adjust from there based on your preference.

Compression Adjustment:

• Compression Damping: The Deluxe Coil Ultimate has a 2-position compression adjustment (Open and Lockout). In the open position, the shock is fully active, allowing it to absorb impacts. The lockout setting is useful for climbing or when you need a more efficient ride with minimal movement.
• How to Adjust: Flip the lever located on the shock body to switch between the two settings. Experiment with the settings depending on the type of terrain.

Spring Rate:

• Customizing the Spring: The coil spring in the Deluxe Coil Ultimate can be swapped out to suit your weight and riding style. The correct spring rate ensures optimal performance and comfort.
• How to Choose the Right Spring: Check the manufacturer’s guide for recommended spring rates based on your body weight. A spring that is too soft may lead to bottoming out, while a spring that is too stiff can result in a harsh ride.

Maintenance of the Deluxe Coil Ultimate Rear Shock

Maintaining the Deluxe Coil Ultimate rear shock is vital for ensuring it performs at its peak [paid link] over time. Here are the best practices for routine maintenance:

Cleaning the Shock:

• After Each Ride: Use a clean rag to wipe down the shock after every ride to remove dirt and debris. This will help prevent buildup that could affect its performance.
• Lubrication: Occasionally, apply a small amount of lubricant to the shock’s mounting points to prevent wear and tear. This will also reduce friction during suspension movement.

Servicing the Coil Spring:

• Inspecting the Spring: Check for signs of wear on the coil spring. Over time, the spring can lose its performance due to constant compression. Replace it when necessary.
• Spring Tuning: Consider upgrading to a different spring rate if you experience issues with bottoming out or excessive stiffness.

Air Can and Damper Maintenance:

• Damper Service: The damper system should be serviced every 50-100 hours of riding, depending on the conditions. This includes replacing the oil and checking seals for any signs of leakage.
• Rebuilding: If the performance of the shock diminishes, consider having a professional rebuild the shock to restore optimal performance.

Troubleshooting Common Set-Up Issues

While the Deluxe Coil Ultimate rear shock is designed for high performance, you might encounter a few setup issues. Here’s how to troubleshoot common problems:

Issue 1: Lack of Rebound Control

• Possible Cause: Incorrect rebound settings or damaged rebound damper.
• Solution: Double-check the rebound dial for proper adjustment. If it still doesn’t feel right, inspect the damper for any signs of wear or leakage. A rebuild may be necessary.

Issue 2: Excessive Bottoming Out

• Possible Cause: Incorrect spring rate or insufficient compression damping.
• Solution: Ensure you have the correct spring rate for your weight. Adjust the compression settings for better support on impacts. If the issue persists, consider switching to a stiffer spring.

Issue 3: Noisy Shock

• Possible Cause: Lack of lubrication or worn bushings.
• Solution: Clean the shock and apply lubrication to the mounting points. Inspect the bushings and replace them if needed.

Customizing the Deluxe Coil Ultimate Rear Shock for Better Performance

Personalizing your Deluxe Coil Ultimate rear shock for enhanced performance is essential for improving comfort and handling. Here are some customization tips:

• Spring Swap: Choose a different coil spring rate to match your riding style. Heavier riders may prefer a stiffer spring, while lighter riders will benefit from a softer spring.
• Adjust Rebound for Terrain: For smoother trails, increase the rebound speed, but for rougher terrain, slow it down for better control.
• Experiment with Compression Settings: The compression settings can be adjusted based on whether you’re climbing or descending. Use the lockout for climbing and switch to open for descending for a plush ride.
