Installation of the Storia V3 Trunnion Rear Shock

Installing the Storia V3 [paid link] Trunnion rear shock requires precision and attention to detail. Follow these steps for a smooth installation:

1. Prepare the bike: Ensure the bike is on a stable surface. You may need to remove the wheel or lower the frame to give yourself room to work.
2. Remove the old shock: If you are replacing an existing shock, remove the bolts securing it to the frame. Be sure to keep track of all parts for reinstallation.
3. Align the shock: Position the Storia V3 [paid link] Trunnion shock in the frame, ensuring the trunnion mount fits correctly in the designated space. The trunnion design requires alignment with the frame’s shock mounting system.
4. Insert the hardware: Use the included mounting hardware to secure the shock. Tighten the bolts to the manufacturer’s recommended torque specifications. This is crucial to ensure proper performance and prevent any damage.
5. Double-check the installation: Verify that the shock is properly seated and the hardware is tightened. There should be no play in the shock, and it should align evenly with the mounting points.

Adjustment and Tuning

One of the major selling points of the Storia V3 Trunnion rear shock is its adjustability, allowing riders to fine-tune the suspension to their preferences. Here’s how to adjust it:

Rebound Adjustment

The rebound dial on the Storia V3 Trunnion shock controls the speed at which the shock returns after compression. Adjusting this dial is crucial for preventing the rear end of the bike from bucking during fast, rough descents.

• Clockwise to slow down rebound: This will reduce the shock’s return speed, providing more control over rough terrain.
• Counterclockwise to speed up rebound: A faster rebound helps maintain traction on smoother trails and quick terrain.

Compression Adjustment

The compression adjuster on the Storia V3 Trunnion allows you to control how much the shock resists compression. Proper compression adjustment is key to keeping your bike stable and absorbing impacts effectively.

• Low-speed compression (LSC): Adjusts how the shock compresses at low speeds (e.g., when riding on smooth terrain). Stiffening this setting provides more support.
• High-speed compression (HSC): Adjusts the shock’s compression under high-intensity hits. A firmer setting helps prevent bottoming out on aggressive impacts.

Air Pressure

The air pressure in the shock can be adjusted to suit the rider’s weight and riding style. This is crucial for achieving the right sag and ride feel.

• To adjust air pressure: Use a shock pump to adjust the pressure. Generally, a starting point is about 30-35% of your body weight in PSI. However, personal preference and riding conditions can alter this.

Maintenance of the Storia V3 Trunnion Rear Shock

Regular maintenance is essential to keep your Storia V3 Trunnion rear shock performing at its best. Here’s how to maintain it:

Cleaning and Lubing

• Routine cleaning: After each ride, especially in muddy or wet conditions, clean the shock with a mild degreaser or water and soap. Avoid direct water pressure on the seals.
• Lubing: Ensure the shock’s moving parts are properly lubricated, particularly around the mounting points and the shock shaft. Use suspension-specific lubricants.

Seal Care

The seals on the Storia V3 Trunnion are designed to prevent dirt and moisture from entering the internals. Inspect the seals regularly for wear and replace them when necessary.

Air Can Maintenance

The air can should be serviced every 50-100 hours of riding. Remove the air can and clean the inner surfaces to prevent any buildup that could compromise performance.

Regular Inspections

Inspect the shock for any signs of damage or wear. Pay attention to the shock’s response during rides; any changes in damping or compression may indicate the need for servicing.

Troubleshooting Common Set-Up Issues

While the Storia V3 Trunnion rear shock is a reliable and high-performance component, occasional issues may arise. Here are common problems and how to address them:

Shock Bottoming Out

• Issue: The shock bottoms out during hard hits or aggressive descents.
• Solution: Adjust the high-speed compression or increase the air pressure to add more resistance during compression.

Poor Rebound Control

• Issue: The rebound feels too slow or too fast, leading to poor control.
• Solution: Adjust the rebound damping dial to achieve a setting that prevents the shock from either feeling too sluggish or springing back too quickly.

Loss of Air Pressure

• Issue: If the shock loses air pressure, it may result in poor performance and inconsistent suspension action.
• Solution: Check for leaks around the air valve or seals. If you notice any issues, re-inflate the shock and inspect for any signs of wear that may require replacing the seals or O-rings.

Customization and Optimization for Better Performance

To truly make the Storia V3 Trunnion rear shock your own, there are several ways to customize it for better performance:

Fine-Tuning for Specific Terrain

• Trail Riding: Set the compression to a softer setting with a moderate rebound speed for comfort and control.
• Enduro or Downhill Riding: Increase compression and adjust the rebound to prevent bottoming out and maintain control at higher speeds.
• Cross-Country Racing: Use a firmer compression setting and quick rebound for optimal speed and pedaling efficiency.

Weight Considerations

The Storia V3 Trunnion offers a variety of settings that can be adapted to different rider weights. Lighter riders should aim for lower air pressure, while heavier riders may need to increase the pressure to prevent excessive sag and improve performance.

Comparison with Other Rear Shocks

When considering rear shock options, the Storia V3 Trunnion is often compared to other high-end models like the Fox Float X2 or the RockShox Super Deluxe.

Storia V3 Trunnion vs Fox Float X2

• Performance: Both shocks excel in terms of adjustability, but the Storia V3 Trunnion is known for its exceptional control over both high-speed and low-speed compression adjustments.
• Weight: The Fox Float X2 tends to be slightly lighter, but the Storia V3 offers more fine-tuning options for serious riders.
• Durability: The Storia V3’s robust design offers a bit more longevity in rougher conditions, making it a better option for riders who regularly tackle aggressive terrain.

Storia V3 Trunnion vs RockShox Super Deluxe

• Customization: The Storia V3 Trunnion offers a higher degree of customization, allowing for more precise tuning of compression and rebound.
• Price: The RockShox Super Deluxe is generally more affordable, but the Storia V3’s added performance features may justify the investment for more experienced riders.

Compatibility with Other Drivetrain Components

The Storia V3 Trunnion rear shock is compatible with most modern mountain bike frames designed for trunnion mounts. However, it’s important to check the compatibility with your bike’s rear triangle and ensure it matches the specifications of the shock. Compatibility is typically not an issue if your frame features a trunnion mounting system and a similar shock length and stroke.

Before upgrading or replacing your shock, verify that the suspension geometry of your bike matches the required specifications for the Storia V3 Trunnion. Some bikes may require a special adapter to fit the shock properly.
