2. Setup

2.1 Installation

For proper and safe installation, it is highly recommended that the RockShox Reba RL Suspension Fork be installed by a qualified bicycle mechanic. Incorrect installation can lead to serious injury or damage to the product.

2.2 Air Pressure Adjustment (Solo Air)

The Reba RL fork utilizes the Solo Air spring system, allowing for easy adjustment of both positive and negative air chambers simultaneously through a single Schrader valve. Refer to the air pressure guide on the fork's lower leg or the official RockShox website for recommended pressure settings based on rider weight and riding style.

1. Locate the Schrader valve cap on the top of the left fork leg.
2. Remove the cap and attach a high-pressure shock pump.
3. Add or release air to achieve the desired pressure.
4. Remove the pump and replace the valve cap.

2.3 Sag Setting

Sag is the amount the suspension compresses under the rider's weight. Proper sag setting is crucial for optimal performance. The Reba RL fork features sag gradients on the stanchion to assist with this process.

1. With the fork at full extension, slide the rubber sag ring (o-ring) down to the wiper seal.
2. Mount your bicycle in your typical riding gear and position.
3. Gently dismount the bicycle without bouncing the suspension.
4. Measure the distance from the wiper seal to the sag ring. This is your sag. Adjust air pressure as needed to achieve the recommended sag (typically 15-25% of travel).

2.4 Rebound Adjustment

Rebound damping controls the speed at which the fork extends after compression. The red rebound knob is located at the bottom of the right fork leg.

• Turn the knob clockwise for slower rebound (more damping).
• Turn the knob counter-clockwise for faster rebound (less damping).

Adjust rebound to prevent the fork from packing up on successive bumps or topping out too quickly.

2.5 Compression/Lockout Adjustment

The blue Motion Control RL damper knob on the top of the right fork leg controls low-speed compression and lockout.

• Turn the knob clockwise to increase low-speed compression damping, making the fork feel firmer.
• Continue turning clockwise to engage the lockout feature, which stiffens the fork for climbing or smooth terrain. The blow-off valve allows the fork to still absorb large impacts even when locked out.
• Turn the knob counter-clockwise to decrease compression damping or disengage the lockout.

3. Operating

The RockShox Reba RL fork is designed for versatile riding. Understanding its features will enhance your riding experience.

3.1 General Riding

For most trail riding, operate the fork in the open compression setting. This allows the fork to absorb bumps and maintain traction effectively. Adjust rebound damping to match terrain and rider preference.

3.2 Using Lockout

The lockout feature is beneficial for climbing steep ascents, riding on smooth roads, or sprinting. It minimizes suspension movement, improving pedaling efficiency. Remember to disengage the lockout when returning to technical terrain to allow the fork to absorb impacts and provide control.

4. Maintenance

Regular maintenance is essential to keep your Reba RL fork performing at its best and to extend its lifespan.

4.1 Cleaning

• After each ride, especially in dirty or wet conditions, wipe down the stanchions (upper tubes) with a clean, soft cloth.
• Clean the seals and the area around the arch to remove dirt and debris.
• Avoid using high-pressure washers directly on seals or bearings.

4.2 Service Intervals

For detailed service schedules, refer to the official RockShox service manual available on their website. Generally, regular lower leg service (cleaning and lubricating foam rings, replacing dust wipers) is recommended every 50 hours of riding or annually, whichever comes first. A full damper and air spring service is typically recommended every 100-200 hours or biennially.

4.3 Inspection

Periodically inspect your fork for any signs of damage, such as scratches on the stanchions, oil leaks, or unusual play. If any issues are found, consult a qualified bicycle mechanic immediately.

5. Troubleshooting

This section addresses common issues you might encounter with your Reba RL fork.

If you experience persistent issues or are unsure about any troubleshooting steps, it is always best to consult a certified RockShox service center or a qualified bicycle mechanic.
