Once installed, you can adjust the fork to your preference and begin the maintenance process.

Adjusting the Boxxer Select RC Fork

Proper adjustment of your Boxxer Select RC is essential for maximizing its performance. The Boxxer Select RC features both compression and rebound adjustments, allowing you to fine-tune the fork to match your riding style and trail conditions.

Rebound Adjustment:

The rebound adjustment knob is located at the bottom of the right fork leg. This controls how quickly the fork returns after compression.

  • To Adjust: Turn the knob clockwise for slower rebound (less bounce back) or counterclockwise for faster rebound (more bounce back). Start with a medium setting and fine-tune based on trail conditions.

Compression Adjustment:

The compression knob is located at the top of the right fork leg. This knob controls the fork’s resistance to compression when you hit obstacles or bumps.

  • To Adjust: Turn the knob clockwise to increase compression (firmer feel) or counterclockwise to decrease compression (softer feel). Test your setting on varied terrain and adjust as needed.

Air Pressure:

For riders using the air-sprung version of the Boxxer Select RC, air pressure plays a significant role in the fork’s performance.

  • To Set Air Pressure: Use a high-quality shock pump to add air to the fork. Begin with the recommended pressure from RockShox’s manual based on your weight and riding style. You can then fine-tune based on how the fork feels during riding.

Routine Maintenance

Routine maintenance will keep your RockShox Boxxer Select RC in optimal condition, preventing premature wear and performance degradation. Perform these tasks regularly, depending on how frequently you ride.

Cleaning:

  • Clean the stanchions (the upper fork tubes) after every ride with a clean rag and a small amount of isopropyl alcohol. This will remove dirt and debris that could damage the seals or reduce fork performance.
  • Ensure the fork’s seals are free from mud and dirt. This can be done by wiping down the lower legs and stanchions, ensuring they are free of debris.

Lubrication:

  • Regularly lubricate the fork’s upper seals with a small amount of RockShox-approved lubrication. This will ensure smooth movement and prevent any squeaking or friction between the stanchions and the lowers.
  • Reapply lubrication after every few rides or whenever the fork feels rough or less responsive.

Oil Change:

  • Fork Oil: Every 50 hours of riding or once a season, perform a fork oil change. Drain the old oil and refill with the correct volume and type of suspension oil. This prevents the fork’s performance from degrading due to old, contaminated oil.
  • Lubrication Oil: Change the lubrication oil in the lowers about every 25 hours or once a season, whichever comes first. This is a relatively simple task but vital for maintaining smooth performance and minimizing friction.

Seals and Dust Wipers:

Inspect the fork’s seals and dust wipers regularly. If you notice any damage or excessive wear, replace them. Faulty seals can lead to dirt and moisture entering the fork, which can quickly degrade its internal components.

Troubleshooting Common Boxxer Select RC Issues

Even the best suspension forks can experience issues from time to time. Here are some common problems and their solutions for the Boxxer Select RC.

Issue 1: Fork Bottoming Out

If you find that the fork is bottoming out too easily on rough terrain, it may be under-inflated or incorrectly set up.

  • Solution: Increase the air pressure or adjust the compression settings to make the fork firmer. You can also consider adding volume spacers to adjust the fork’s bottom-out resistance.

Issue 2: No Rebound or Poor Rebound Control

A lack of rebound or poor rebound adjustment is often related to improper settings or air pressure.

  • Solution: Check the rebound knob settings, making sure it’s neither too slow nor too fast. Also, verify that the air pressure is within the recommended range, as incorrect pressure can affect the rebound function.

Issue 3: Fork Feels Sluggish or Harsh

If the fork feels sluggish or harsh, it may be due to too much compression damping or old fork oil.

  • Solution: Adjust the compression settings to soften the fork’s response. Also, perform an oil change if the fork has not been serviced in a while.

Customizing the Boxxer Select RC Fork for Better Performance

The Boxxer Select RC is highly customizable, allowing you to tweak the fork for better handling and performance suited to your riding style. Here are some ways to optimize its capabilities:

Volume Spacers:

Adding volume spacers will adjust the fork’s progression, giving you more bottom-out resistance. This is particularly useful for aggressive downhill riders who need more control during high-impact landings.

Custom Air Pressure:

Experiment with different air pressures to fine-tune the fork for your weight and riding style. Lower air pressure can provide a softer feel, ideal for smoother trails, while higher pressure offers better support for aggressive riding and rough terrain.

Tuning the Compression and Rebound:

Frequent adjustments to the compression and rebound damping allow you to tailor the fork to different trail conditions. By fine-tuning these settings, you can adjust how the fork handles obstacles and maintains control at high speeds.
