• Torque wrench [paid link]
• 5mm and 6mm Allen wrenches [paid link]
• Shock pump
• Clean cloth or rag
• Soft rubber mallet (optional)
• Loctite (optional, for securing bolts)

Installation of the Storia V3 Trunnion Rear Shock

Installing the Storia V3 Trunnion rear shock requires precision and careful attention to detail. Here’s a step-by-step guide to help you install the shock correctly:

1. Prepare the Bike: Remove the existing rear shock if necessary. Clean the mounting points on the frame to ensure there’s no dirt or debris that could affect the installation.
2. Position the Shock: Align the shock’s trunnion mount with the corresponding mount on the bike frame. Ensure the shock is oriented correctly, with the damper adjustments facing outward for easy access.
3. Insert the Bolts: Slide the shock into place, ensuring that the eyelets and bushings fit correctly into the mount. Insert the mounting bolts through the eyelets and tighten them by hand.
4. Torque the Bolts: Using a torque wrench [paid link], tighten the mounting bolts to the manufacturer’s recommended torque specification. Over-tightening can damage the shock, so it’s essential to follow the correct torque values.
5. Install the Shock Pump: Attach the shock pump to the valve and set the recommended air pressure for your rider weight. Use the pump to inflate the shock to the desired pressure, and ensure the shock operates smoothly.
6. Final Check: Check the shock’s movement to ensure that it compresses and rebounds without any resistance or unwanted noise. Make sure that all bolts are securely tightened.

Adjustment and Tuning for Optimal Performance

The Storia V3 Trunnion rear shock provides a wide range of adjustment options to customize the ride. To get the best performance out of your shock, make sure to adjust the following settings based on your weight, riding style, and terrain:

1. Rebound Adjustment

Rebound control determines how quickly the shock returns to its original position after compression. Adjusting this can help maintain control on rough terrain and ensure that the rear wheel stays in contact with the ground. If the shock rebounds too quickly, it can cause the bike to bounce, while too slow a rebound can result in sluggish performance.

• Turn the rebound dial clockwise for slower rebound (less bounce).
• Turn the dial counterclockwise for faster rebound (more bounce).

2. Compression Adjustment

The compression setting controls how the shock absorbs impacts. By adjusting the compression, you can tailor the shock to better handle small bumps or large hits.

• Increase compression for a firmer feel and better support on rough terrain.
• Decrease compression for a softer feel and improved comfort over smaller bumps.

3. Bottom-Out Adjustment

This optional feature helps reduce harsh bottoming out during high-impact landings or deep compressions. The hydraulic bottom-out adjustment can be dialed in to give you a more controlled and smooth response during hard hits.

• Turn the adjustment knob to dial in the bottom-out resistance based on the terrain you plan to ride.

Troubleshooting Common Set-Up Issues

Despite the Storia V3 Trunnion rear shock’s advanced design, you may encounter a few setup issues during installation or use. Below are some common problems and their solutions:

1. Shock Won’t Hold Air

If the shock is losing air pressure over time, it could be due to a faulty valve or a damaged air seal. Inspect the shock valve for leaks, and check the seals for any visible damage. If you find a problem, replacing the seals or servicing the shock may be necessary.

2. Excessive Rebound or Compression

If the shock is too bouncy or feels too stiff, it could be due to improper adjustment of the rebound or compression settings. Start by setting both adjustments to the middle range and fine-tune from there based on your riding experience.

3. Noise or Creaking Sounds

If the shock produces unusual noise, check the mounting hardware to ensure all bolts are tightened correctly. Lubricate the mounting points with a suitable grease to reduce friction and prevent squeaks. Also, inspect the shock bushings for wear and replace them if needed.

Customization and Optimization

To optimize the performance of the Storia V3 Trunnion rear shock for your specific needs, consider the following adjustments:

• Volume Spacers: Volume spacers allow you to adjust the air spring curve to suit your preferences. Adding spacers can increase mid-stroke support, while removing them can provide a more linear feel.
• Air Pressure: Fine-tuning the air pressure based on your weight and riding style is crucial. Lighter riders may require less pressure, while heavier riders may need to increase pressure for optimal performance.

Comparison with Similar Rear Shocks

The Storia V3 Trunnion rear shock is often compared to other high-end models like the Fox DHX2 and the RockShox Super Deluxe. However, the Storia V3 Trunnion excels in terms of fine-tuned damping adjustments and smoothness on aggressive terrain. While the Fox DHX2 offers similar features, it often feels firmer, making the Storia V3 a better choice for riders seeking a plush and progressive feel.

Compatibility with Other Drivetrain Components

The Storia V3 Trunnion rear shock is compatible with most modern mountain bike frames that feature a trunnion mount. It works well with other drivetrain components, including SRAM and Shimano drivetrains. Be sure to check your frame’s specifications to confirm compatibility, as some frames may have specific requirements for rear shock fitment.
