2. Setup

2.1 Unpacking and Inspection

Carefully remove the fork from its packaging. Inspect for any signs of shipping damage. Ensure all components, including the axle and remote lever (if applicable), are present.

2.2 Installation

Professional installation by a qualified bicycle mechanic is highly recommended. Incorrect installation can lead to serious injury or damage to the product.

1. Steerer Tube Preparation: Cut the steerer tube to the appropriate length for your bicycle frame and stem. Ensure proper headset stack height.
2. Crown Race Installation: Install the crown race onto the steerer tube.
3. Fork Insertion: Insert the fork into the head tube of your bicycle frame.
4. Stem and Spacers: Install any necessary headset spacers and the stem.
5. Top Cap and Preload: Install the top cap and adjust headset preload according to your headset manufacturer's specifications.
6. Brake Caliper Installation: Mount your disc brake caliper to the fork's post-mount tabs. Ensure proper alignment and torque specifications are met.
7. Wheel Installation: Install the front wheel using the Kabolt axle. Ensure the axle is fully seated and tightened to the specified torque.

2.3 Initial Adjustments

Before riding, set up the fork's air pressure and rebound damping for your weight and riding style.

• Air Pressure (SAG):
  • Locate the air valve on the top of the left fork leg.
  • Attach a high-pressure shock pump.
  • Add or release air until the desired SAG (Suspension Air Gap) is achieved. Refer to FOX's official SAG setup guide for recommended percentages based on riding style.
• Rebound Damping:
  • The rebound adjuster is located at the bottom of the right fork leg.
  • Turn the red knob clockwise for slower rebound (more damping) and counter-clockwise for faster rebound (less damping).
  • Start with the recommended setting from FOX's tuning guide and fine-tune based on trail conditions and personal preference.
• FIT4 Damper Adjustments:
  • The FIT4 damper offers three main compression settings: Open, Medium, and Firm (controlled by the remote).
  • In the Open mode, there is an additional black micro-adjust knob for fine-tuning low-speed compression. Turn clockwise for more compression, counter-clockwise for less.

3. Operating Instructions

3.1 FIT4 Damper Operation

The FIT4 damper provides on-the-fly compression damping adjustments to adapt to varying terrain and riding styles.

• Open Mode: Provides full suspension travel and maximum small bump compliance. Ideal for technical descents and rough terrain.
• Medium Mode: Offers increased compression damping for improved pedaling efficiency on rolling terrain or smoother climbs.
• Firm Mode: Provides a near-lockout feel for maximum pedaling efficiency on smooth climbs or sprints.

3.2 Remote Adjust Functionality

The 2-position remote allows for quick transitions between the Open and Firm modes.

• Engaging Firm Mode: Press the remote lever to engage the Firm (lockout) mode. This provides a rigid platform for climbing or sprinting.
• Engaging Open Mode: Press the release button on the remote lever to return the fork to the Open mode, allowing full suspension travel.

4. Maintenance

Regular maintenance is crucial for the longevity and optimal performance of your FOX fork.

4.1 Cleaning

• After every ride, wipe down the stanchions (upper tubes) with a clean, soft cloth to remove dirt and debris.
• Use mild soap and water for general cleaning of the fork lowers. Avoid high-pressure washers directly on seals.
• Do not use harsh chemicals or solvents, as they can damage seals and finishes.

4.2 Lubrication

• Periodically apply a small amount of suspension-specific lubricant to the stanchions, just above the dust wipers. Cycle the fork a few times to distribute the lubricant, then wipe off any excess.

4.3 Service Intervals

FOX recommends regular service to maintain performance and prevent wear. Refer to the official FOX website for the most current service interval recommendations, which typically include:

• Every 30 hours of riding or annually (whichever comes first): Lower leg service (dust wiper and foam ring replacement, bath oil change).
• Every 125 hours of riding or annually (whichever comes first): Full fork service (damper and air spring service).

These intervals may vary based on riding conditions and intensity. Always use genuine FOX parts and fluids for service.
