The Storia V3 Trunnion [paid link] rear shock from EXT represents a pinnacle of performance and design in the realm of mountain bike suspension. Known for its superior damping capabilities and advanced tuning features, this rear shock offers riders a unique experience in terms of control, responsiveness, and comfort. In this guide, we will delve deep into its installation, maintenance, troubleshooting, and optimization, helping you understand why the Storia V3 Trunnion [paid link] is a standout choice for serious riders.

Installation of the Storia V3 Trunnion Rear Shock

Installing the Storia V3 [paid link] Trunnion rear shock correctly is essential to ensure optimal performance. Here’s a step-by-step guide to get you started:

Tools Required:

Installation Steps:

  1. Prepare the Bike: Remove the rear wheel and ensure the frame is clean and free from debris.
  2. Remove the Old Shock: If you’re replacing an existing rear shock, use the 5mm Allen wrench to loosen the bolts attaching the shock to the frame. Carefully remove it, ensuring you do not damage the frame or the shock mount.
  3. Prepare the Storia V3 [paid link] Trunnion Shock: Before installing the new shock, make sure it’s clean. Apply a small amount of grease to the mounting hardware to prevent creaking.
  4. Attach the Shock to the Frame: Align the Trunnion shock’s eyelets with the mounts on the frame. Use the 8mm Allen wrench to insert and tighten the bolts, ensuring the shock is properly secured.
  5. Check the Alignment: Once attached, ensure the shock sits correctly and is not under any undue stress. The mounting hardware should be secure without any play.
  6. Set the Sag: Use a shock pump to adjust the pressure according to your body weight and riding style. Ensure the shock is inflated to the recommended pressure for optimal performance.
  7. Final Tightening: Use the torque wrench [paid link] to tighten the bolts to the manufacturer’s recommended torque values (typically around 20-30 Nm for the rear shock bolts).
  8. Test the Shock: Perform a final check by compressing the shock manually. Ensure it moves freely without any resistance or unusual sounds.

Adjustment and Maintenance of the Storia V3 Trunnion Rear Shock

Regular maintenance and fine-tuning of the Storia V3 Trunnion are key to maximizing its lifespan and performance. The rear shock features adjustable damping and rebound settings, making it highly customizable for different riding conditions.

Compression and Rebound Adjustment:

The Storia V3 Trunnion allows you to adjust both the compression and rebound settings to fine-tune your ride. Here’s how:

  1. Compression Adjustment: The shock features a three-position compression knob, allowing you to adjust the level of damping.
    • Open: Offers maximum sensitivity and plushness for rough terrain.
    • Medium: Provides a balance of support and comfort for mixed conditions.
    • Firm: Provides a stiffer feel, ideal for smooth, fast trails.
  2. Rebound Adjustment: The rebound adjuster allows you to control how quickly the shock returns after compression. Adjusting the rebound speed helps maintain stability and control when the shock extends. For faster trails, you may prefer a quicker rebound, while slower, technical descents may require a slower rebound.

Regular Maintenance:

  1. Clean the Shock: After every ride, wipe the shock clean using a microfiber cloth. This prevents dirt and grime from accumulating, which can lead to damage over time.
  2. Check for Leaks: Inspect the shock for any signs of oil leakage, which could indicate a damaged seal.
  3. Lubricate the Mounting Hardware: Every few rides, apply a small amount of grease to the mounting bolts and hardware to ensure smooth movement and to prevent creaks.
  4. Service Intervals: EXT recommends servicing the Storia V3 Trunnion shock annually or after every 200 hours of riding, depending on usage. Regular servicing will help maintain the shock’s performance and prevent major issues down the line.

Troubleshooting Common Setup Issues

While the Storia V3 Trunnion is engineered for performance, certain setup issues can occasionally arise. Here’s how to troubleshoot common problems:

Problem 1: Shock Not Responding to Damping Adjustments

  • Cause: This may be due to incorrect pressure settings or an issue with the internal oil.
  • Solution: Double-check the shock’s pressure using a shock pump. If the pressure is correct, perform a basic check to ensure that the damping circuits are functioning. If the shock still does not respond [paid link], consider servicing the shock.

Problem 2: Loss of Air Pressure

  • Cause: A slow leak could occur due to damaged seals or improperly tightened valves.
  • Solution: Inspect the valve and seals for damage. Tighten the valve to ensure there are no air leaks. If the issue persists, a more thorough inspection or service might be required.

Problem 3: Unusual Noises from the Shock

  • Cause: Noises such as squeaks or creaks can come from improper mounting, worn-out bushings, or lack of lubrication.
  • Solution: Make sure the shock is properly mounted with the right torque settings. Apply lubrication to the shock’s mounting points to prevent squeaks.

Customization and Optimization for Better Performance

The Storia V3 Trunnion rear shock’s adjustability allows you to fine-tune it for different riding styles and terrain. Here are some tips for optimizing the shock’s performance:

Tailoring the Shock to Your Riding Style:

  1. Trail Riding: For trail riding, set the compression to the “Medium” setting and adjust the rebound to suit the trail’s speed. This ensures good control while maintaining comfort.
  2. Enduro: For enduro riding, use the “Firm” compression setting for better support on aggressive descents, and adjust the rebound for faster recovery on bigger jumps.
  3. Downhill: For downhill racing, use the “Open” setting to soak up the big hits and ensure the shock absorbs the harsh terrain without bottoming out.

Tuning for Weight and Conditions:

  • Body Weight: Adjust the shock’s air pressure based on your body weight and riding style. Heavier riders may need to increase the air pressure for more support, while lighter riders may benefit from a lower pressure setting for a more plush ride.
  • Terrain: Consider the type of terrain you’ll be riding on when adjusting your shock. For rocky, technical terrain, the “Open” compression setting may be ideal, while smoother trails may benefit from a firmer shock setup.

Comparison with Similar Models

When compared to other rear shocks in its category, the Storia V3 Trunnion stands out due to its advanced damping technology, which provides more precision and control. While other brands may offer solid rear shocks, the Storia V3 excels in its tunability and durability, making it a top choice for aggressive riders.

  • Fox Float X2: Known for its plush feel, the Fox Float X2 is another high-performance shock. However, the Storia V3 offers more fine-tuned adjustments, particularly in terms of compression and rebound.
  • RockShox Super Deluxe: The Super Deluxe is competitive, offering a durable, low-maintenance shock. However, the Storia V3 shines with its advanced damping features, making it better suited for riders who want more customization.

Understanding Compatibility with Other Drivetrain Components

The Storia V3 Trunnion rear shock is highly versatile [paid link], but it’s important to ensure compatibility with your bike’s frame and other components. The shock’s trunnion mount design allows for easier integration with a wide range of frames, though you must confirm that the shock’s specifications align with the bike’s geometry and intended use.

Ensure the frame has a suitable trunnion mount, as this is a key feature for secure attachment. Compatibility with other drivetrain components like the rear derailleur and cassette should not present any issues, as the shock’s role is primarily to affect the suspension rather than the drivetrain.

By ensuring proper integration of all components, the Storia V3 Trunnion can deliver its full potential in providing smooth, responsive suspension performance across various riding conditions.
