Installation of the Storia V3 Trunnion Rear Shock
Installing the Storia V3 [paid link] Trunnion rear shock requires a careful and precise approach to ensure optimal function. The rear shock should be mounted properly on the frame to avoid any issues with alignment or performance.
Step 1: Preparation
Before installing the shock, clean both the shock mounting points on the frame and the shock itself. Use a clean rag and suspension cleaner to remove any debris, dust, or grease. This ensures that the shock mount will be secure and that the shock will function properly once installed.
Step 2: Shock Mounting
Align the Storia V3 [paid link] Trunnion shock with the frame’s mounting points. The trunnion mount design allows for easy installation as long as the shock is aligned properly with the frame’s trunnion interface. Slide the shock’s mounting bolts into position and secure them with the appropriate Allen keys [paid link]. Use a torque wrench [paid link] to tighten the bolts to the recommended torque specification (usually around 25 Nm, but check your manufacturer’s manual to confirm).
Step 3: Air Pressure and Setup
The Storia V3 Trunnion rear shock comes with an adjustable air spring, which you will need to set based on your weight and riding style. Attach a shock pump to the air valve and increase the air pressure to the desired level. Make small adjustments based on the rider’s weight, terrain preferences, and riding style.
Adjustment of the Storia V3 Trunnion Rear Shock
The Storia V3 Trunnion rear shock offers several adjustment features to help you fine-tune your suspension for optimal comfort and performance.
Rebound Adjustment
The rebound adjustment controls how quickly the shock returns after compression. Too fast and the bike may feel bouncy, while too slow can make the bike feel sluggish. To adjust the rebound, turn the rebound dial located on the base of the shock. Clockwise will slow the rebound, while counterclockwise will speed it up.
Compression Adjustment
Compression damping regulates the shock’s response to impacts and terrain. The Storia V3 Trunnion features a high-speed and low-speed compression adjustment. The high-speed compression adjusts the shock’s reaction to larger impacts, while the low-speed compression affects how the shock reacts to smaller, repetitive hits. Adjust both to match your riding style and terrain.
Volume Spacers
The Storia V3 Trunnion allows you to add or remove volume spacers to adjust the shock’s progression. If you’re looking for a more linear feel or more progressive bottom-out resistance, volume spacers are a useful tool. Adding spacers will make the shock ramp up faster, increasing the bottom-out resistance.
Maintenance of the Storia V3 Trunnion Rear Shock
Regular maintenance is essential to keep your Storia V3 Trunnion performing at its best. Here’s how to maintain the shock for optimal performance.
Cleaning the Shock
After every ride, wipe down the shock with a clean, dry rag. Pay special attention to the seals and shock shafts, as dirt and debris can negatively impact the shock’s performance. Using isopropyl alcohol can help remove any grease or grime from the shock’s surface.
Checking for Leaks
Check for any signs of oil or air leaks around the shock’s seals and mounting points. If you notice any leakage, the seals may need to be replaced. It’s important to address leaks promptly to prevent any performance issues.
Suspension Fluid Changes
Over time, the suspension fluid inside the shock will degrade. Depending on how often you ride, you should plan to replace the suspension fluid every 100-150 hours of use. To do this, you’ll need to disassemble the shock, clean out the old fluid, and refill it with the correct type of fluid recommended by EXT. This process is crucial for maintaining smooth performance and preventing wear on the shock internals.
Troubleshooting Common Set-up Issues
If you’re encountering issues with your Storia V3 Trunnion rear shock, here are some common problems and their solutions:
1. Lack of Rebound Control
If the rebound adjustment isn’t providing the desired damping, it could be a sign of low suspension fluid or a worn-out seal. If the fluid is low, a fluid change should resolve the issue. If the issue persists, check the seals for damage and replace them if necessary.
2. Poor Air Pressure Retention
If the shock is not holding air pressure, there could be a leak in the air chamber. Check the Schrader valve and air seal for any signs of wear. If air pressure continues to drop, it may be time to replace the seals.
3. Bottoming Out Too Easily
If your shock is bottoming out too often, consider increasing the air pressure or adding more volume spacers. Additionally, check the compression settings to ensure they are optimized for your riding style and terrain.
Customization and Optimization for Better Performance
The Storia V3 Trunnion rear shock is designed for customization to suit a wide variety of riding styles and terrain conditions. Here are some tips for optimizing your shock’s performance:
Tuning for Different Terrain
For aggressive downhill riding, increase the compression damping and add more volume spacers to prevent the shock from bottoming out on big hits. For cross-country riding, reduce the compression damping and lower the air pressure to create a more responsive and plush feel.
Fine-Tuning for Rider Preferences
The Storia V3 Trunnion allows you to fine-tune the shock’s settings based on your weight, skill level, and terrain. Experiment with different air pressures, rebound settings, and compression adjustments to find the perfect balance for your needs.
Comparison with Similar Models
When comparing the Storia V3 Trunnion to similar rear shock models, several key features stand out. While many rear shocks in this class offer adjustability and performance, the Storia V3 Trunnion is particularly known for its smoothness and precise control. Its high-end damping systems and ability to customize both high-speed and low-speed compression make it a superior choice for riders seeking maximum performance and control.
Compared to other models, such as the Fox DHX2 or RockShox Super Deluxe, the Storia V3 Trunnion offers more options for precise tuning and is often preferred by riders who demand a high level of adjustability.
Compatibility with Other Drivetrain Components
The Storia V3 Trunnion rear shock is designed to be compatible with a wide range of frames and drivetrain systems. Its trunnion mount design allows it to fit various frames, especially those designed for performance-oriented builds. When selecting a drivetrain, ensure that your frame’s geometry and suspension requirements match the shock’s specifications for optimal performance.
Proper compatibility with your frame and drivetrain components will ensure that the shock works in harmony with the rest of your bike’s systems, offering a smooth, responsive ride.
