The Storia V3 [paid link] rear shock by EXT is a high-performance suspension system designed for serious mountain bikers. One of the most important aspects of optimizing the performance of the Storia V3 [paid link] is properly setting the sag. Sag is the amount the shock compresses under the rider’s weight and is crucial for achieving the correct balance of comfort and control. This guide will walk you through the process of setting the sag on the Storia V3, including installation, adjustment, troubleshooting, and tips for fine-tuning the shock’s performance.

Tools Required

• Shock pump
• Measuring tape or ruler
• Marker or tape (for reference marks)
• External air pressure gauge (optional)

Understanding Rear Shock Sag

Sag refers to how much the rear shock compresses under the rider’s weight. It’s essential for achieving optimal performance because it ensures the suspension responds correctly to terrain without bottoming out or feeling too stiff. For the Storia V3, setting the correct sag allows the suspension to function within its intended range and provides the best balance between comfort and control.

Typically, mountain bike rear shock sag should be between 25% to 30% of the shock’s total travel. For the Storia V3, which offers a variety of configurations, the ideal sag setting is generally around 30%. However, this can vary depending on the rider’s weight, riding style, and terrain.

Installing the Storia V3 Rear Shock

Step 1: Remove the Existing Shock

If you are replacing an old shock, use a 5mm Allen wrench [paid link] or the appropriate tool to remove the shock from your frame. Pay attention to the orientation and positioning of the shock so you can install the new one correctly.

Step 2: Install the Storia V3 Rear Shock

Position the Storia V3 shock in its mount points on the frame. Secure the upper and lower mounting bolts tightly but do not over-torque them, as this could damage the shock or the frame. Be sure to check the alignment of the shock and ensure that it moves freely.

Step 3: Attach the Air Hose

The Storia V3 uses an air spring, so you’ll need to connect the shock pump to the air valve. Ensure the pump is securely attached before proceeding to adjust the air pressure.

Setting the Sag on the Storia V3

Step 1: Find the Correct Pressure

Before you can set the sag, you must first determine the correct air pressure. For the Storia V3, this pressure is generally based on your body weight. Start with the recommended range from the manufacturer’s guidelines, which typically provides a starting point for your air pressure.

Step 2: Prepare the Shock for Measurement

Put on your riding gear, including your hydration pack, and get onto the bike. You should be in your typical riding position, fully equipped, so the sag is as accurate as possible under your real-world conditions.

Step 3: Set the Reference Mark

Before sitting on the bike, use a piece of tape or a marker to mark the position of the shock’s stanchion (the upper portion of the shock) relative to its outer tube. This will serve as a reference point for measuring the sag.

Step 4: Sit on the Bike and Measure

Once you’re seated on the bike, let the shock compress under your weight and get into a relaxed, neutral position. With your weight evenly distributed, check how much the shock compresses from the initial reference point. You can either use the shock’s built-in measurements or a measuring tape to check the distance.

Step 5: Adjust the Air Pressure

If the sag is too high (less compression), you’ll need to reduce the air pressure by releasing some air from the shock. If the sag is too low (too much compression), add more air. The ideal sag for the Storia V3 is generally around 30% of the shock’s total travel.

Step 6: Test Ride

Once you’ve set the correct sag, take the bike for a test ride. Pay attention to how the shock feels over rough terrain. If the shock feels too stiff or too soft, return to the shock pump to make additional adjustments.

Troubleshooting Common Set-Up Issues

Issue 1: Too Much Sag (Shock Bottoming Out)

If you notice the shock bottoming out frequently, this likely means that the sag is too high. Increase the air pressure to stiffen the suspension and prevent bottoming out. Recheck the sag after each adjustment.

Issue 2: Not Enough Sag (Shock Feeling Too Stiff)

If the shock feels too stiff and doesn’t compress enough, the sag is too low. Release some air to allow the shock to compress more easily. Re-test the sag after adjusting.

Issue 3: Inconsistent Performance

If the shock feels inconsistent, it could be due to incorrect pressure or inadequate rebound settings. Double-check both your air pressure and rebound damping settings. Adjust the rebound to suit your riding style for a smoother performance.

Customizing the Storia V3 for Optimal Performance

Adjusting Rebound

The Storia V3 features external rebound adjustments. By adjusting the rebound, you can fine-tune how fast or slow the shock returns after compression. For more aggressive riding, a faster rebound may be preferable, while a slower rebound can enhance control on rough terrain.

Compression Damping

The Storia V3 also offers adjustable compression damping. This allows you to modify how the shock compresses under load. If you’re riding in rough conditions, increase the compression damping to control harsh impacts. For smoother trails, decrease the compression damping for better comfort.

Fine-tuning Air Pressure

Depending on the type of riding you do, you may need to make small adjustments to the air pressure over time. Lighter riders may require lower pressure, while heavier riders will need more air for proper sag. Keep track of these adjustments to ensure your suspension remains responsive.

Compatibility with Other Drivetrain Components

The Storia V3 rear shock is designed to be compatible with most modern mountain bike frames that accept an air shock. However, it is important to confirm the shock’s specifications match your frame’s requirements. The Storia V3 is best paired with a frame designed for air suspension, which offers the most effective performance.

It is also essential to ensure that your bike’s linkage and suspension design are compatible with the Storia V3’s travel range and mounting system. Some frames may require specific adapters or mounting hardware, which should be provided by the manufacturer.

Conclusion

Setting the correct rear shock sag on the Storia V3 is essential for optimal performance. By carefully adjusting the air pressure, testing the sag, and making fine-tuned adjustments to rebound and compression, you can enhance your riding experience. With the right setup, the Storia V3 will provide superior comfort, control, and responsiveness across various terrains. Follow these steps and troubleshooting tips to get the most out of your rear shock, ensuring it works in harmony with your bike for the best possible ride.
