• Flathead screwdriver
• Bike stand [paid link]
• Brake caliper spacer
• Crown race press (if needed)
• Cable tie or zip tie

Step-by-Step Installation

1. Prepare the bike: Place the bike in a work stand, removing the front wheel and any existing suspension fork if applicable.
2. Install the crown race: If the Reba RL is replacing an old fork, you may need to remove the old crown race. Install the new crown race that comes with the Reba RL using a crown race press to ensure proper fitting.
3. Install the fork into the head tube: Slide the Reba RL fork through the head tube and into the headset. Ensure it is correctly aligned before tightening the headset bolts.
4. Attach the brake caliper: Secure the brake caliper to the fork. If needed, install a brake caliper spacer to protect the caliper while setting up.
5. Align the handlebars and tighten: Once the fork is installed, align the handlebars to ensure they are straight. Tighten the stem bolts using the correct torque settings.
6. Install the front wheel: Place the front wheel into the fork dropouts, securing it tightly.
7. Check fork travel and compression settings: Before riding, adjust the Reba RL’s air pressure and compression settings to your desired settings (refer to the Reba RL manual for the right settings based on your rider weight).

After installation, ensure that the fork moves smoothly through its travel. A simple test on the ground will allow you to check if everything is properly aligned and functioning.

Adjusting the Reba RL for Optimal Performance

The Reba RL fork is equipped with various adjustment features that allow you to fine-tune the performance based on your weight, riding style, and the trail conditions.

Air Spring Adjustments

The Reba RL uses an air spring system for suspension. You can adjust the air pressure to set the right amount of sag for your body weight. This allows the fork to absorb impacts and provide maximum comfort.

• Set the air pressure: Use a shock pump to adjust the air pressure. Start by checking the recommended settings based on your weight and rider preferences.
• Check sag: To find the proper air pressure, measure the sag. Sag is the amount the fork compresses under your body weight, usually between 15-20% of the fork’s total travel.

Rebound Adjustment

Rebound adjustment controls how quickly the fork returns to its original position after compression. If the rebound is too fast, the fork will feel “bouncy.” If it’s too slow, the fork might not return fully, reducing control.

• Set the rebound: Turn the rebound knob on the bottom of the left leg of the fork. Start with a middle setting and fine-tune based on how the fork feels when riding.
• Test ride: On your test ride, adjust the rebound until you find a setting that feels smooth and responsive but doesn’t result in excessive bouncing.

Lockout Adjustment

The Reba RL also features a lockout adjustment that helps reduce the fork’s movement on smooth terrain or during climbing. This feature is especially useful to prevent unwanted suspension travel, increasing pedaling efficiency.

• Engage or disengage lockout: The lockout lever is located on the top of the right fork leg. Lock out the fork on smooth trails or during uphill climbs, and unlock it when descending or riding technical sections.

Maintaining Your Reba RL Fork

Regular maintenance is crucial for keeping the Reba RL fork in top shape. Dirt, mud, and moisture can all cause performance issues if not properly cleaned.

Cleaning the Fork

• Wipe the stanchions: After each ride, use a clean rag to wipe the stanchions to remove dirt and debris. This will keep the seals clean and prolong the life of the fork.
• Inspect the seals: Check the seals for any damage or wear. If the seals become worn, replace them promptly to prevent dirt and moisture from entering the fork.

Servicing the Air Spring

• Regularly check air pressure: The air spring should be checked every 1-2 months. Changes in air pressure can affect your ride, so keep it at the recommended level.
• Replace air seals: If you notice any loss of pressure or sagging, it might be time to replace the air seals. Consult the manual for proper servicing instructions.

Replacing Fork Oil

The damper in the Reba RL fork contains oil that can degrade over time. Replacing the oil can help restore performance.

• Oil change interval: Generally, fork oil should be replaced every 50-100 hours of riding, depending on riding conditions.
• Service procedure: If you’re unfamiliar with the process, it’s best to take the fork to a professional bike mechanic to ensure it is done correctly.

Troubleshooting Common Issues with the Reba RL

Though the Reba RL fork is highly reliable, you might encounter a few issues during use. Here’s how to troubleshoot some of the most common problems.

Fork Doesn’t Move Smoothly

• Cause: This could be due to insufficient air pressure, dirty seals, or low oil levels.
• Solution: Check and adjust the air pressure to your rider weight. Clean the seals and replace them if necessary. If the issue persists, consider changing the fork oil.

Fork Sinks Too Much or Doesn’t Sag Properly

• Cause: Incorrect air pressure is typically the cause of improper sag.
• Solution: Adjust the air pressure according to the guidelines for your weight. If it still doesn’t sag correctly, inspect the seals for any damage or wear and replace them if needed.

Rebound Is Too Fast or Too Slow

• Cause: The rebound adjustment may be set incorrectly.
• Solution: Adjust the rebound setting by turning the dial to a slower or faster setting, depending on the issue. If it still doesn’t work, the damper may need servicing.

Customizing Your Reba RL Fork for Better Performance

Customization of the Reba RL fork can drastically improve your riding experience, depending on the type of trails you tackle and your specific preferences.

• Upgrade the air spring: You can upgrade to a different air spring or modify the air pressure to fit your specific needs, such as more plushness for aggressive trails or firmer settings for cross-country racing.
• Install a firm lockout: If you prefer a firmer lockout for efficient climbing, you may opt for a more aggressive compression tune for better control during climbs.

Comparing the Reba RL to Other Fork Models

When considering the Reba RL fork, it’s essential to compare it with other similar models in the RockShox lineup, such as the RockShox Recon or the RockShox SID.

• Reba RL vs. Recon: The Recon is a more robust fork, designed for rougher terrain with a wider range of adjustability and a larger chassis. It is typically better for aggressive riders, while the Reba RL is lighter and more suited for cross-country and moderate trail riding.
• Reba RL vs. SID: The SID fork is designed for cross-country racing and offers a more performance-oriented feel with lower weight. While the Reba RL offers more adjustability for general trail riding, the SID focuses on maximum efficiency for racing.

Compatibility with Other Drivetrain Components

The Reba RL fork is designed to be compatible with most standard 100mm and 110mm quick-release and thru-axle front wheels. However, it’s important to confirm the axle compatibility before installation. The fork can be paired with a variety of drivetrain components but always ensure that the fork’s travel, axle type, and headset compatibility align with your bike frame and other components.
