To ensure your fork stays in optimal condition, regular maintenance is essential. This guide will cover everything you need to know about installing, adjusting, maintaining, troubleshooting, and optimizing the SR Suntour Axon Werx [paid link] suspension fork.

Tools Required

  • Suspension fork grease
  • 5mm and 6mm Allen wrenches [paid link]
  • Flathead screwdriver
  • Torque wrench [paid link]
  • Clean rags or towels
  • Suspension fluid (specific to SR Suntour forks)
  • Stanchion seal tool or fork seal driver
  • Fork seal cleaner
  • Small brush or toothbrush
  • Replacement parts (seals, bushings, oil)

Installation of the Axon Werx Fork

The installation of the SR Suntour Axon Werx fork is straightforward, but it’s important to follow the correct steps to avoid damaging any components or compromising the performance of the fork.

  1. Prepare the Fork and Bike: Before you start, ensure your bike is clean and secure on a work stand. Remove the front wheel and, if necessary, the handlebars to allow easy access to the fork.
  2. Install the Fork: Slide the fork’s steerer tube into the head tube of your bike frame. Ensure that the headset and bearing cups are in place. Tighten the top cap bolt using a 5mm Allen wrench [paid link]. Be cautious not to overtighten.
  3. Align and Secure: Align the fork so it is straight and tighten the fork pinch bolts on the fork’s lower legs. The Axon Werx features a 15mm thru-axle, so secure the axle to ensure the fork is stable and the wheel is properly mounted.
  4. Final Torque Check: Using a torque wrench [paid link], check the torque specifications for your Axon Werx fork and ensure that all bolts are torqued correctly. Refer to the SR Suntour manual for the precise values.

Adjustment of the Axon Werx Fork

Fine-tuning your suspension fork ensures better performance and comfort while riding. The Axon Werx fork allows for several adjustments, including air pressure, rebound, and compression settings.

Air Pressure Adjustment

The Axon Werx features an air spring system, which means you can adjust the air pressure to suit your weight and riding style. Proper air pressure is crucial for maintaining the right balance of comfort and control.

  1. Check Rider Weight: Use the manufacturer’s recommended air pressure range based on your weight. It’s important to check this range in the SR Suntour user manual for the Axon Werx.
  2. Adjust the Air Pressure: Using a high-pressure pump, set the correct air pressure by inflating or deflating the air chamber. Start with the recommended pressure and fine-tune it based on your feel during test rides. If the fork feels too soft or too firm, adjust the pressure accordingly.
  3. Recheck and Test: After adjustment, test the fork’s feel by pushing down on it. The fork should compress and rebound smoothly without bottoming out or feeling too stiff.

Rebound and Compression Adjustment

The Axon Werx fork allows for fine-tuning of rebound and compression to improve the fork’s performance.

  1. Rebound Adjustment: Locate the rebound adjuster at the bottom of the right leg of the fork. Turning it clockwise increases rebound damping (slows the return), while turning it counterclockwise decreases rebound damping (speeds up the return). Adjust the rebound setting to ensure the fork returns smoothly after compression, avoiding any bouncing.
  2. Compression Adjustment: Compression damping controls how the fork responds to impacts. Turn the compression knob, usually located at the top of the left leg, to adjust the compression damping. A firmer setting is better for aggressive riding, while a softer setting is more suitable for cross-country riding.

Regular Maintenance

Maintaining your SR Suntour Axon Werx fork requires regular cleaning and periodic servicing to keep it performing at its best. Here’s a step-by-step guide on how to care for your fork:

Cleaning and Lubricating the Fork

  1. Clean the Stanchions: After each ride, wipe down the fork’s stanchions with a clean rag to remove dirt and grime. This helps to prevent the accumulation of debris in the seals and ensures smooth operation.
  2. Lubricate the Seals: Apply a small amount of suspension fork grease to the seals using a clean brush or your fingers. This helps to keep them well-lubricated and free from contaminants.

Inspect and Replace Seals

  1. Remove the Fork Leg: Using the appropriate tools, remove the fork leg to access the internal components. Be sure to keep track of any parts you remove and take care not to damage seals or other components.
  2. Clean and Replace Seals: Inspect the seals for wear or damage. If necessary, replace them with new SR Suntour seals designed for the Axon Werx fork. Be sure to clean the fork’s internals before reassembling it.
  3. Reassemble the Fork: After replacing seals and cleaning the internals, reassemble the fork carefully, ensuring all parts are properly lubricated and in place.

Suspension Fluid Change

Every 50-100 hours of riding or once a year, you should change the suspension fluid. This ensures the fork continues to operate smoothly and prevents internal wear.

  1. Disassemble the Fork: Carefully remove the lowers of the fork and drain any old suspension fluid. Take care to note the amount and type of fluid used.
  2. Clean the Fork: Once the fluid is drained, clean the internal components thoroughly before refilling the fork with new fluid.
  3. Refill with New Fluid: Refill the fork with the recommended suspension fluid, ensuring that you use the correct type for the Axon Werx fork. Follow the manufacturer’s guidelines for the appropriate amount.
  4. Reassemble the Fork: Reassemble the fork, ensuring all components are properly aligned and lubricated. Test the fork before heading out on a ride.

Troubleshooting Common Issues

Even with regular maintenance, you may encounter issues with your SR Suntour Axon Werx fork. Below are some common problems and how to troubleshoot them:

Fork Not Rebounding Properly

  • Cause: Incorrect rebound setting or low oil levels.
  • Solution: Check the rebound adjuster and adjust it if necessary. If the problem persists, inspect the oil level inside the fork and top up if needed.

Fork Feeling Too Soft or Too Hard

  • Cause: Incorrect air pressure settings.
  • Solution: Adjust the air pressure according to your weight and riding style. If you feel the fork is too soft, increase the air pressure; if it’s too hard, decrease it.

Leaking Suspension Fluid

  • Cause: Worn seals or damage to the fork.
  • Solution: Inspect the seals and replace any that appear worn. If the issue persists, consider taking the fork to a professional for servicing.

Customization and Optimization

To optimize the performance of your Axon Werx fork, you can fine-tune the settings according to your specific needs. Adjusting the air pressure, rebound, and compression will make a noticeable difference in handling and comfort.

  1. Riding Style Considerations: If you’re an aggressive rider, increase the compression damping and air pressure to reduce bottoming out. For cross-country or lighter riders, softer settings will improve comfort and traction.
  2. Terrain Adaptation: Adjust the fork’s settings based on the terrain you ride. For technical trails, stiffening the fork will improve control, while for smoother, flowy trails, softer settings provide a more comfortable ride.

Compatibility with Other Drivetrain Components

The Axon Werx fork is designed to be compatible with most modern road and mountain bike drivetrains. However, always check for compatibility with your specific bike frame, headset, and wheel setup before purchasing.

  • Headset Compatibility: Ensure the fork’s steerer tube diameter matches your bike’s headset specifications.
  • Wheel Compatibility: The Axon Werx fork is designed for 15mm thru-axles. Ensure that your wheels are compatible with this axle type.
  • Brake Compatibility: The Axon Werx fork is compatible with both disc and rim brakes. Be sure to check the brake mount specifications to ensure proper alignment and performance.

By following these maintenance tips and adjusting the fork according to your needs, you can keep your SR Suntour Axon Werx fork performing at its best for years to come.
