Installing the Axon Werx Fork

Preparing the Fork

Before installing the Axon Werx fork, ensure your bike frame is compatible with the fork’s steerer tube size and brake mounts. The Axon Werx features a tapered steerer tube, so check the headset dimensions and compatibility with your bike.

Step-by-Step Installation

1. Remove the Old Fork: Begin by removing the existing suspension fork or rigid fork from the bike frame. Use an Allen wrench [paid link] to loosen and remove the headset top cap, fork bolts, and any mounting hardware.
2. Install the Axon Werx Fork: Slide the fork’s steerer tube into the headset, ensuring it fits securely in the head tube.
3. Adjust Fork Position: Position the fork so that the desired amount of steer tube is exposed above the headset. Ensure that it is aligned correctly and properly centered.
4. Secure the Fork: Tighten the headset bolts to the manufacturer’s recommended torque setting. Be sure not to overtighten, as this can cause damage to the steerer tube or headset bearings.
5. Install the Front Wheel: Mount the front wheel, ensuring the axle is properly aligned in the fork dropouts. Tighten the wheel axle to the appropriate torque setting.

Final Adjustments

Once the fork is installed, check for proper alignment and fork movement. Test the fork by pressing down on the handlebars to check its responsiveness. Adjust the air pressure and rebound settings (see the “Setting Up Your Suspension” section for more details) for optimal performance.

Setting Up Your Suspension

Air Pressure Adjustment

The Axon Werx fork uses air pressure to adjust the suspension’s overall firmness. To set the air pressure:

1. Locate the Air Valve: On the top of the fork, you’ll find the air valve. Use an air pump with a pressure gauge that is compatible with suspension forks.
2. Adjust for Rider Weight: The air pressure depends on the rider’s weight and the type of terrain you ride on. For most riders, the recommended pressure range is between 80-120 psi, but it’s crucial to consult the manufacturer’s guidelines.
3. Inflate the Fork: Attach the pump to the air valve and inflate the fork to the desired pressure. Be sure to check the air pressure regularly, as it can drop over time due to temperature changes or normal usage.

Rebound Adjustment

Rebound control helps manage how quickly the fork returns to its normal position after compression. For the Axon Werx fork:

1. Locate the Rebound Knob: This is typically located on the bottom of the fork’s right leg.
2. Adjust the Knob: Turn the rebound knob to adjust the fork’s return speed. A slower rebound is ideal for rougher terrain, while a faster rebound works well for smoother surfaces.

Compression Settings

If your Axon Werx fork includes external compression adjustments, use the knob or dial to control how the fork responds to bumps and shocks. For maximum efficiency, set the compression to match the terrain you’re riding on.

Maintaining Your Axon Werx Fork

Cleaning the Fork

Maintaining cleanliness is vital for optimal suspension fork performance. Regularly clean the fork legs and stanchions to remove dirt and debris, which can cause wear over time.

1. Wipe the Fork Legs: Use a damp cloth to wipe down the fork, paying special attention to the stanchions.
2. Clean the Seals: If necessary, use a brush or a soft rag to clean around the fork seals to prevent dirt from entering the suspension system.

Lubing the Seals

Proper lubrication of the fork seals helps prevent premature wear and ensures smooth movement. Apply a small amount of suspension-specific grease to the seals, but avoid excessive amounts that could cause contamination.

Regular Oil Changes

To maintain optimal performance, it is recommended to change the suspension fluid at regular intervals—typically every 50-100 hours of riding, depending on usage. Over time, the oil inside the fork can become contaminated, affecting damping performance.

1. Remove the Fork: Detach the fork from the bike, following the steps in the installation section.
2. Drain the Old Oil: Remove the fork’s lower leg bolts and allow the old oil to drain completely into a pan.
3. Refill with Fresh Oil: After draining, refill with the appropriate amount and type of suspension fluid recommended by SR Suntour for the Axon Werx model.
4. Reassemble: Once the oil is changed, reassemble the fork and check for any leaks or improper function.

Troubleshooting Common Issues

Fork Not Responding to Adjustments

If the fork is not responding to air pressure or rebound adjustments, check the air valve for leaks. It’s also possible that the fork’s internal components may need servicing, including oil replacement or damper cleaning.

Poor Suspension Performance

If you notice that the suspension feels too soft or too firm, double-check the air pressure and rebound settings. Ensure that the fork is set up according to your weight and riding style.

Noisy Fork

A noisy fork can be caused by inadequate lubrication, dirt buildup, or worn seals. Clean and lubricate the fork, paying special attention to the stanchions and seals.

Customizing Your Axon Werx Fork for Better Performance

Adjusting Travel and Stiffness

Some Axon Werx models allow for customization in terms of travel and stiffness. You can adjust the air pressure to change the overall ride feel, and for some models, changing the spring rate may provide better performance on different types of terrain.

Installing a Lockout Feature

If your Axon Werx fork does not have a lockout feature, you can install an aftermarket lockout lever to reduce bobbing during climbing or on flat terrain. This is particularly useful for riders who use the fork for both road and trail cycling.

Comparing Axon Werx with Similar Fork Models

When choosing a suspension fork, it’s essential to compare the Axon Werx to other models available on the market. Compared to other SR Suntour options like the Aion or Raidon, the Axon Werx tends to offer a more refined damping system and lighter weight, making it ideal for performance-oriented riders.

1. Axon Werx vs Aion: The Aion is a great fork for more aggressive trail riding, while the Axon Werx is better suited for endurance riders seeking lightweight performance. The Axon Werx’s air spring system also offers better fine-tuning.
2. Axon Werx vs Raidon: The Raidon is more budget-friendly, but the Axon Werx offers superior compression adjustments and a more precise air spring system, making it the better choice for competitive riders.

Compatibility with Other Drivetrain Components

The Axon Werx fork is designed to work seamlessly with a wide range of drivetrain components, especially in terms of wheel size compatibility (typically 29” or 27.5”). Ensure that the fork’s axle standard (e.g., quick release or thru-axle) is compatible with your wheelset. Additionally, if you’re using hydraulic disc brakes, check the brake mount compatibility to ensure proper installation.

By ensuring compatibility and optimizing the Axon Werx fork with the right components, you can enhance overall bike performance and achieve a smoother, more responsive ride.
