Installation of the Storia V3 Trunnion Rear Shock

Installing the Storia V3 Trunnion is a straightforward process, but it requires attention to detail to ensure optimal performance. Here’s a step-by-step guide:

Tools Required

• Torque wrench [paid link]
• 5mm and 6mm Allen wrenches [paid link]
• Grease
• Shock pump
• 8mm socket wrench

Installation Process

1. Prepare the Frame: Ensure that the rear shock mounting points on the bike frame are clean and free from dirt or debris.
2. Install the Mounting Hardware: Apply a light layer of grease to the shock’s mounting hardware, ensuring that the bushings are properly installed.
3. Attach the Shock: Align the trunnion mount of the shock with the frame. Secure the shock using the appropriate bolts and tighten them to the manufacturer’s recommended torque specification.
4. Adjust Air Pressure: Use a shock pump to adjust the air pressure according to your rider weight and desired sag. Refer to the recommended sag range in the user manual for best results.
5. Set Initial Damping Settings: Begin with the default settings for compression and rebound damping. These can be fine-tuned later based on your riding preferences.

Maintenance of the Storia V3 Trunnion Rear Shock

Regular maintenance is essential to ensure the Storia V3 Trunnion performs optimally over time. Here are key maintenance practices:

Cleaning and Lubrication

• Clean the Shock: After each ride, wipe down the shock with a clean cloth to remove any dirt or mud. Pay special attention to the shock’s eyelet and mounting areas.
• Lubricate the Seals: Apply a small amount of oil or lubricant to the shock’s seals to prevent them from drying out and causing friction.

Air Spring Pressure

• Check and Adjust Air Pressure: Over time, air pressure can fluctuate due to temperature changes or air leakage. It’s important to check and adjust air pressure regularly to maintain proper sag and ensure the shock operates efficiently.

Rebound and Compression Tuning

• Rebound Adjustment: Test the rebound damping regularly by compressing the shock and observing how it returns. Adjust the rebound setting to suit your riding style, ensuring that the shock returns quickly enough to maintain control but not too fast to cause bouncing.
• Compression Adjustment: Fine-tune the compression settings based on the terrain. On rough trails, increase compression to minimize bottoming out, while reducing it on smoother trails to enhance comfort.

Troubleshooting Common Issues with the Storia V3 Trunnion Rear Shock

Despite its premium build, issues can arise over time with any high-performance shock. Here are common problems and their solutions:

1. Excessive Rebound or Slow Return

• Cause: This could be caused by an improperly adjusted rebound setting or low air pressure.
• Solution: Check the rebound settings and adjust according to your preference. Ensure air pressure is within the recommended range.

2. Squeaking or Noise During Operation

• Cause: A common issue is lack of lubrication in the shock’s bushings or dirt accumulating in the mounting area.
• Solution: Clean the shock thoroughly and apply appropriate lubricant to the bushings and seals.

3. Sag Issues

• Cause: If the sag is too deep or not enough, it may be due to incorrect air pressure.
• Solution: Adjust the air pressure using a shock pump to meet the recommended pressure for your weight and riding style.

4. Bottoming Out Too Often

• Cause: If the shock is bottoming out on rough terrain, it may be due to insufficient compression damping or low air pressure.
• Solution: Increase the compression damping and check the air pressure to ensure it is within the recommended range.

Customization and Optimization for Better Performance

One of the key advantages of the Storia V3 Trunnion is the level of customization it offers. Riders can optimize their shock settings to suit their riding style and terrain.

• Fine-tuning Compression and Rebound: Adjusting both compression and rebound settings allows you to adapt the shock to varying conditions, whether you’re riding technical descents, rough trails, or smoother paths.
• Air Spring Pressure: By adjusting the air spring pressure, riders can fine-tune the shock’s performance to match their body weight and desired sag.
• Custom Tuning: The Storia V3 Trunnion can also be custom-tuned by EXT or specialized bike shops to match specific riding preferences or optimize for particular types of terrain.

Comparing the Storia V3 Trunnion with Competitor Rear Shocks

The Storia V3 Trunnion competes with several other high-performance shocks on the market. Here’s a comparison with some of the top models:

1. Fox Float X2

• Performance: The Fox Float X2 is a strong competitor, known for its adjustable damping and smooth ride quality. However, the Storia V3 Trunnion offers slightly better responsiveness due to its trunnion mount design, which is more efficient at transferring forces.
• Customization: Both shocks provide excellent adjustability, but the Storia V3 offers more precise tuning with its wider range of settings.
• Weight: The Fox Float X2 is generally lighter, which may be an advantage for riders focused on weight savings. However, the Storia V3 is optimized for durability and performance, making it a better option for aggressive riders.

2. RockShox Super Deluxe Ultimate

• Performance: The Super Deluxe Ultimate is another strong competitor in the premium shock category. While it offers great compression and rebound adjustments, the Storia V3 stands out for its superior damping performance and responsiveness, particularly on technical descents.
• Adjustability: The RockShox Super Deluxe Ultimate offers similar levels of adjustability, but the Storia V3’s trunnion design allows for better integration and smoother travel.
• Durability: Both shocks are built for durability, but the Storia V3’s components and seals are more robust, making it a better option for long-term performance.

Compatibility with Other Drivetrain Components

The Storia V3 Trunnion is compatible with most modern mountain bike frames designed for trunnion-mount rear shocks. However, it is essential to check the frame’s specifications before purchasing. The shock’s air pressure and damping settings can be adjusted to suit a wide range of rider weights and styles, making it highly versatile [paid link] in terms of compatibility with other components.

The shock pairs well with high-performance drivetrains like SRAM and Shimano, offering a well-balanced ride with minimal energy loss. It is crucial to ensure that the bike frame and rear shock are both designed to work together, as improper mounting can affect the shock’s performance.

In conclusion, the Storia V3 Trunnion is a high-performance rear shock that excels in providing adjustable, responsive, and smooth ride quality.
