The Storia V3 Trunnion [paid link] rear shock from EXT is designed to provide superior performance and handling for serious riders. Known for its refined damping and customizable features, the Storia V3 Trunnion [paid link] has become a popular choice for high-end mountain bikes and road bikes that demand top-notch suspension systems. In this article, we will take an in-depth look at the performance of the Storia V3 [paid link] Trunnion rear shock, covering its installation, adjustment, maintenance, troubleshooting, and optimization for better performance.
Installation of Storia V3 Trunnion Rear Shock
Step 1: Preparation
Before installing the Storia V3 [paid link] Trunnion rear shock, ensure you have all the necessary tools. Make sure your bike is securely placed on a stand and that you’re working in a clean environment.
Step 2: Remove the Old Shock
If you’re replacing an old rear shock, start by removing the bolts that secure it to the frame. Use a torque wrench [paid link] to ensure that the bolts are properly tightened when removing them. Be cautious not to damage any surrounding components or the shock itself during the removal process.
Step 3: Install the Storia V3 Trunnion Shock
Place the Storia V3 Trunnion shock into the frame’s mounting points. Ensure that the shock is aligned properly with the trunnion mount before securing it. Tighten the mounting bolts carefully, ensuring that they are torqued to the manufacturer’s specifications. Use the torque wrench [paid link] to achieve the correct tension to prevent over-tightening or under-tightening, both of which could affect the shock’s performance.
Step 4: Check for Proper Installation
Once the shock is installed, check for any play in the mounting points and ensure the shock is securely fixed in place. Double-check the alignment to ensure no friction is present in the shock’s travel.
Adjustment of Storia V3 Trunnion Rear Shock
Air Pressure Adjustment
The Storia V3 Trunnion rear shock comes with an air spring system, which requires proper air pressure to function optimally. To adjust the air pressure:
- Use a shock pump to adjust the pressure based on your weight and riding style.
- Begin with the recommended pressure range provided by EXT. You may need to fine-tune the pressure by testing the shock’s response during rides.
- It is important to check air pressure regularly, as it can fluctuate with temperature and use.
Rebound and Compression Adjustments
The Storia V3 Trunnion rear shock features separate rebound and compression adjustments, allowing for precise tuning:
- Rebound: Adjust the rebound knob to control the speed at which the shock returns to its original position after compression. A slower rebound is ideal for controlling fast, aggressive hits, while a faster rebound setting works better for smoother, less demanding terrain.
- Compression: The compression knob adjusts how the shock reacts to hits and impacts. A higher compression setting is ideal for heavy, rough trails, while a softer setting is better for smoother trails or comfort-focused rides.
Fine-Tuning for Ride Comfort
To achieve the best performance, fine-tune both the rebound and compression settings based on your riding preferences. If you prefer a more plush feel, reduce compression and slow the rebound. Conversely, for aggressive riding or tackling steeper terrain, increase compression for better control and reduce rebound speed to prevent bucking.
Maintenance of Storia V3 Trunnion Rear Shock
Cleaning and Lubing
To ensure long-lasting performance, regular maintenance is essential. After every few rides or after a particularly muddy or wet ride:
- Clean the shock using a soft cloth and water. Avoid harsh chemicals that could damage seals or reduce performance.
- Lubricate the moving parts of the shock lightly with a suitable lubricant, focusing on the shock’s stanchions and moving seals.
Regular Inspection of Seals and Bushings
Inspect the seals, bushings, and mounting hardware at least once every season or after every 100 hours of riding. Look for signs of wear or damage, such as oil leaks, visible cracks, or loose mounting bolts.
- If you notice any leaks, replace the seals immediately to prevent dirt or water from entering the shock.
- Keep the mounting hardware tightened to specification to avoid play in the shock.
Air Spring Maintenance
The air spring in the Storia V3 Trunnion shock can lose air over time. Check the air pressure before each ride, and top it off if necessary. Over time, air spring seals may wear, requiring re-lubing or replacement.
Troubleshooting Common Set-Up Issues
Loss of Air Pressure
One common issue with rear shocks is a loss of air pressure. If you notice a decrease in performance, check the shock for any visible damage. If there are no external leaks, inspect the Schrader valve for any damage. If the valve seems fine but air continues to escape [paid link], it may be necessary to replace the internal seals or bushings.
Insufficient Compression or Rebound
If the compression or rebound settings feel inadequate, double-check that the knobs are properly adjusted. Ensure the damping system is not clogged with dirt or debris. Regular maintenance and cleaning can prevent this from becoming a recurring issue.
Noisy Shock
If your Storia V3 Trunnion shock is making unusual noises, check for any loose mounting bolts, which may cause friction during the shock’s movement. Tighten all bolts to the correct torque. If the noise persists, inspect the shock’s internal parts for any damage or wear.
Customization and Optimization for Better Performance
Weight Considerations
Riders can fine-tune the performance of the Storia V3 Trunnion shock by adjusting the air pressure based on their weight. The shock’s performance changes with different weight loads, so ensuring the correct air pressure will optimize the suspension’s responsiveness to terrain.
Terrain-Specific Adjustments
For riders who frequently ride on different types of terrain, the Storia V3 Trunnion’s adjustability allows for terrain-specific tuning:
- For rocky, technical trails: Increase compression and slow the rebound to handle sudden, harsh impacts.
- For smoother trails: Lower compression and speed up the rebound to make the ride more comfortable and efficient.
External Modifications
While the Storia V3 Trunnion shock offers comprehensive adjustments, some riders may look to external modifications, such as changing the shock’s seals or upgrading the oil for different performance characteristics. Consult with experts before making such modifications to ensure compatibility with your bike’s frame and other components.
Comparison with Similar Models
When comparing the Storia V3 Trunnion to other high-performance rear shocks, it stands out in terms of its exceptional adjustability and durability. While models from brands like Fox and RockShox also provide solid performance, the Storia V3 Trunnion excels in delivering a customizable ride, especially for riders who prioritize fine-tuned settings for maximum comfort and control.
Unlike many competitors, the Storia V3 Trunnion uses a unique damping system that offers an incredibly smooth response over varied terrain, making it ideal for riders who tackle everything from technical climbs to aggressive descents. The shock’s trunnion mount also adds to its stability, ensuring a more solid connection with the frame and offering improved performance under load.
Understanding Compatibility with Other Drivetrain Components
The Storia V3 Trunnion rear shock is designed to work with a wide range of drivetrain components. However, it is important to ensure that the shock is compatible with your bike’s frame and other suspension components:
- Frame Mounting: The trunnion mount design may not be compatible with every frame. Be sure to check your bike’s specifications to confirm that it supports trunnion-mounted shocks.
- Drivetrain Integration: The shock’s performance can be influenced by your bike’s geometry, suspension linkages, and drivetrain setup. Ensure that the shock works harmoniously with your drivetrain to avoid performance issues.
- Dropper Seatposts: If you’re using a dropper seatpost, make sure that the routing does not interfere with the shock. Proper integration of all suspension components will optimize the overall performance.
The Storia V3 Trunnion rear shock’s performance benefits from close attention to its compatibility with your bike’s overall setup, ensuring that the suspension works at its best in tandem with other key components.
