It combines advanced technology with user-friendly adjustability to provide an exceptional riding experience. In this guide, we will cover everything you need to know about installing, maintaining, adjusting, troubleshooting, and optimizing the Boxxer Select RC [paid link] to get the best out of your ride.

Tools Required

• 5mm and 6mm hex wrenches
• Suspension oil (specific to the Boxxer)
• Fork seal grease
• Torque wrench [paid link]
• Flathead screwdriver
• 10mm socket wrench
• Stanchion cleaner (optional)

Installation of the Boxxer Select RC

The installation of the Boxxer Select RC is a straightforward process, but it requires attention to detail to ensure everything is set up correctly. Follow these steps to get your fork installed:

1. Remove the Old Fork: Begin by removing your old suspension fork if applicable. Loosen the stem and headset bolts using a 5mm hex wrench, then remove the fork from the frame.
2. Install the Boxxer Select RC Fork: Place the new fork into the frame’s headset and align the steerer tube to the correct length. Ensure that the fork is centered and positioned securely.
3. Tighten the Headset and Stem: Use a 5mm hex wrench to tighten the headset bolts, making sure the fork is positioned properly. Follow this by tightening the stem bolts with the appropriate torque specifications.
4. Adjust the Steerer Tube: If necessary, trim the steerer tube to the correct length using a saw designed for cutting steel. Be careful to ensure that the cut is straight to avoid damaging the components.
5. Install the Front Wheel: Place the front wheel in the fork dropouts and tighten the thru-axle or quick-release mechanism securely.
6. Check for Correct Alignment: Spin the wheel and check that the fork moves smoothly without any resistance. Ensure that the brake caliper is aligned with the rotor and that everything is properly assembled.

Adjusting the Boxxer Select RC

The Boxxer Select RC offers a range of adjustments, including rebound and compression, to suit different riders’ needs and riding styles. Proper adjustment ensures that you get the maximum performance from the fork. Here’s how to adjust the key settings:

Compression Adjustments

The Boxxer Select RC features external compression adjustment for both high and low-speed settings. These settings control the fork’s responsiveness to various trail conditions.

1. Low-Speed Compression: Adjust the low-speed compression to fine-tune how the fork reacts to small bumps and chatter. Turn the knob clockwise to increase compression, making the fork stiffer. Turn it counterclockwise for a softer feel, allowing the fork to absorb smaller impacts more effectively.
2. High-Speed Compression: The high-speed compression adjustment affects how the fork handles larger impacts like drops or fast compressions. Adjust it by turning the knob clockwise to make the fork more resistant to harsh impacts or counterclockwise to make it more forgiving.

Rebound Adjustment

Rebound adjustment controls how quickly the fork returns to its normal position after compression. This setting is important for maintaining control and stability on fast descents.

• To adjust rebound: Use the rebound knob located at the bottom of the fork’s right leg. Turn it clockwise to slow down the rebound and counterclockwise to speed it up. The correct setting will depend on your weight and the terrain you’re riding on. A slower rebound setting is generally preferable for rough terrain, while faster settings work better for smoother trails.

Air Spring Pressure

The air spring in the Boxxer Select RC plays a crucial role in adjusting the fork’s feel. Adjust the air pressure to suit your weight and riding style.

• To adjust air pressure: Use a high-pressure pump to add or remove air from the fork’s air chamber. The recommended air pressure is usually indicated in the user manual, but you can experiment with different pressures to achieve the ideal balance between plushness and support.

Maintenance of the Boxxer Select RC

Regular maintenance is essential for keeping your Boxxer Select RC fork in peak [paid link] condition. Here are the key maintenance tasks to perform:

Cleaning and Lubing the Fork

1. Clean the Stanchions: Before every ride, use a clean cloth to wipe down the fork’s stanchions. This prevents dirt and grime from entering the seals, which can cause premature wear.
2. Lubricate the Seals: Apply a small amount of suspension-specific grease to the fork’s seals. This will keep them lubricated and help prevent dirt buildup. Be sure to use grease that is compatible with the materials in the fork.

Changing the Oil

The Boxxer Select RC uses suspension oil that needs to be changed periodically to maintain optimal performance. Over time, the oil can degrade and lose its ability to dampen the fork effectively. Follow these steps to change the oil:

1. Disassemble the Fork: Remove the fork from the bike and separate the lower leg from the upper part of the fork.
2. Drain the Oil: Drain the old oil into a container and dispose of it properly.
3. Refill with Fresh Oil: Using the recommended suspension oil for the Boxxer Select RC, refill the fork’s lower legs according to the manufacturer’s specifications.
4. Reassemble the Fork: Carefully reassemble the fork, ensuring all parts are correctly aligned and torqued to the specified values.

Fork Seals and Bushings

Inspect the fork seals and bushings regularly for any signs of wear. If the seals are leaking oil or dirt is getting into the fork, it’s time to replace them. This will ensure smooth fork action and avoid further damage to the internals.

Troubleshooting Common Boxxer Select RC Issues

Despite being a robust and reliable fork, you may encounter a few issues with your Boxxer Select RC. Here are some common problems and solutions:

Fork Feels Too Stiff or Too Soft

• Problem: If the fork feels either too stiff or too soft, it could be due to incorrect air spring pressure.
• Solution: Check and adjust the air pressure according to your weight and riding style. If you’re unsure of the correct pressure, refer to the manufacturer’s guidelines.

Rebound Is Too Fast or Too Slow

• Problem: If the fork is rebounding too quickly or too slowly, it’s a sign that the rebound setting needs adjustment.
• Solution: Adjust the rebound knob to a slower or faster setting depending on the trail conditions. If this doesn’t resolve the issue, it might be time for a fork rebuild.

Fork Makes a Knocking or Popping Noise

• Problem: Knocking or popping noises may indicate that the fork’s bushings are worn out or that there’s debris inside the fork.
• Solution: Clean and lubricate the fork’s seals and check the bushings for wear. If necessary, replace the bushings or perform a full suspension service.

Customization and Optimization

To optimize the performance of your Boxxer Select RC, consider these customization options:

• Spring Rate: For heavier or lighter riders, adjusting the spring rate can make a significant difference in the fork’s feel. Check with your local bike shop for different spring options if needed.
• Compression and Rebound Tuning: Fine-tuning the low and high-speed compression as well as the rebound settings will tailor the fork’s performance to your specific riding style and trail conditions.
• Upgrade Seals and Dampers: If you’re looking for a smoother ride and better performance, upgrading the seals or damper system could be beneficial.

Compatibility with Other Drivetrain Components

The Boxxer Select RC is designed to work seamlessly with a range of bike components, especially those intended for downhill or aggressive trail riding. It is compatible with various frame geometries and brake systems, including disc brakes. However, always double-check that the fork’s axle type (thru-axle or quick-release) matches your frame and wheelset. Additionally, ensure that the fork’s travel is appropriate for your bike’s intended use.
