The RockShox ZEB Select+ suspension fork is engineered for aggressive riders seeking a robust and reliable performance on challenging terrain. With its large chassis, high-performance damping system, and easy customization options, it’s a perfect choice for enduro and downhill riders. However, to get the most out of your ZEB Select+, proper tuning is essential. This guide will walk you through the installation, adjustment, maintenance, troubleshooting, and optimization of the ZEB Select+ suspension fork to enhance its performance on the trail.

Installation of ZEB Select+ Suspension Fork

Installing the ZEB Select+ suspension fork is relatively straightforward, but attention to detail is important for ensuring the best performance.

Step-by-Step Installation

1. Remove the Old Fork: If you’re replacing an existing fork, remove it by loosening the axle and the stem bolts. Detach any cables or accessories.
2. Install the New ZEB Select+: Slide the fork into the head tube of your frame, ensuring it’s centered and aligned.
3. Attach the Stem: Tighten the stem bolts evenly. Ensure the fork’s steerer tube is at the correct height, and the headset bearings are properly installed.
4. Install the Axle: Insert the axle through the fork’s dropouts and tighten it securely. Make sure the axle is correctly aligned with the wheel.
5. Check the Alignment: Ensure the fork is aligned with the front wheel and the handlebars for a straight and true setup.

Tools Required for Installation:

• 5mm and 6mm Allen wrenches [paid link]
• Torque wrench [paid link] (recommended for precise tightening)
• 15mm socket wrench for axle
• Headset press and crown race setter (for headset installation)
• Fork oil (if servicing the fork during installation)

Adjusting ZEB Select+ Suspension Forks

The ZEB Select+ offers a wide range of adjustability to match your riding style and terrain. The key adjustments on the fork include rebound, compression, and air pressure. Here’s how to tune each of these settings:

1. Rebound Adjustment

The rebound setting controls how quickly the fork returns after compressing. Adjusting this correctly ensures that the fork doesn’t bounce too fast or too slow, providing optimal control.

• To Adjust: Turn the rebound knob, located at the bottom of the fork’s right leg. Turning the knob clockwise decreases the rebound speed (slower return), while counterclockwise increases the rebound speed (faster return).
• Tips: Start with the rebound set to a neutral position, then adjust based on the terrain. For smoother trails, you may want a faster rebound; for more technical or rough terrain, slow the rebound for better control.

2. Compression Adjustment

The compression adjustment controls how the fork reacts to impacts. The ZEB Select+ features both high-speed and low-speed compression adjusters.

• To Adjust: The low-speed compression knob is located at the top of the left fork leg. Turn it clockwise to firm up the fork, which is helpful for pedaling efficiency or smoother terrain. Counterclockwise softens the fork for better traction on rougher surfaces.
• High-speed compression: For aggressive riding or rough terrain, high-speed compression may be needed. The ZEB Select+ has an additional high-speed compression adjuster that helps fine-tune fork performance for big hits and fast terrain.

3. Air Pressure Adjustment

Air pressure in the fork’s air spring dictates the fork’s overall feel and support. Too much air pressure can make the fork feel stiff, while too little can make it overly soft and bottom out.

• To Adjust: Use a shock pump to add or release air from the air spring. The correct pressure is typically specified on the side of the fork or in the user manual. It is recommended to start with the pressure guidelines and fine-tune it based on rider weight and riding style.
• Tips: A common starting point is to set the pressure so that the fork sags about 20-30% of its total travel when you’re on the bike.

Maintenance of ZEB Select+ Suspension Fork

Regular maintenance is critical to keeping your ZEB Select+ performing at its best. Here’s a basic guide to maintaining your fork.

1. Cleaning

After every ride, wipe down the fork with a clean, damp cloth to remove dirt and debris from the stanchions. This prevents contaminants from entering the seals and damaging the fork’s internals.

2. Lubing the Seals

Lubricating the fork seals keeps them supple and prevents them from drying out. Apply a thin layer of suspension-specific grease or oil to the stanchions during cleaning. This helps maintain smooth travel and minimizes wear.

3. Fork Oil Changes

Changing the fork oil at regular intervals ensures the fork’s damping system functions optimally. Over time, fork oil can degrade and cause poor performance or excessive friction.

• To Change Fork Oil: Remove the fork from the bike, disassemble the lowers, and drain the old oil. Refill the lowers with fresh suspension oil, following the manufacturer’s recommended weight and quantity.

4. Spring Maintenance

If your ZEB Select+ uses a coil spring, inspect the spring regularly for any signs of damage, corrosion, or wear. Coil springs may require occasional lubrication to ensure smooth operation.

Troubleshooting Common Issues with ZEB Select+

Understanding common problems with the ZEB Select+ suspension fork can help you quickly identify and resolve issues. Here are some common concerns:

1. Fork Bottoming Out

If the fork frequently bottoms out, it could be due to insufficient air pressure or improper compression settings.

• Solution: Increase the air pressure slightly or adjust the compression damping to firm up the fork. Ensure the sag is set correctly.

2. Lack of Rebound Control

If the fork feels too sluggish or bounces excessively, there may be an issue with the rebound adjustment or fork oil.

• Solution: Adjust the rebound to a faster or slower setting, depending on the issue. If the issue persists, consider changing the fork oil.

3. Noisy Fork

Squeaking or knocking sounds may occur due to dirt or debris in the fork or damaged seals.

• Solution: Clean the stanchions and check the seals for wear or damage. Lubricate the seals and stanchions if necessary.

Customizing and Optimizing ZEB Select+ for Better Performance

Fine-tuning your ZEB Select+ can greatly enhance your riding experience, especially if you’re looking to get the most out of your suspension.

1. Tuning for Different Terrain

The ZEB Select+ is versatile and can be tuned for various types of terrain. On smooth trails, you may prefer a firmer fork with less rebound. For aggressive downhill riding, you’ll want a softer, more responsive fork with slower rebound and more air in the spring.

2. Adjusting for Rider Weight

Your body weight impacts how the fork behaves. Heavier riders may need to run a higher air pressure to prevent bottoming out, while lighter riders may require less pressure to achieve the ideal amount of sag and performance.

ZEB Select+ vs. Other Suspension Fork Models

Comparing the ZEB Select+ to other suspension forks in the market, such as the RockShox Lyrik or the Fox 36, it’s clear that the ZEB Select+ is designed for riders who demand maximum strength and performance for aggressive enduro and downhill riding.

• ZEB Select+: Offers a stiff chassis and a highly adjustable air spring for tackling demanding trails. It is heavier compared to some of its competitors but provides more robust performance for high-speed and technical riding.
• Lyrik: Lighter and better suited for all-mountain riding, but with slightly less stiffness in the chassis when compared to the ZEB.
• Fox 36: Similar performance to the ZEB Select+, but some riders find the Fox 36 to be more tunable for cross-country and trail-specific riding.

Compatibility with Other Drivetrain Components

The ZEB Select+ is compatible with a wide range of drivetrains, as it uses a standard 15mm or 20mm thru-axle and works with most modern frame designs. Ensure that your frame has the appropriate steerer tube diameter and that the fork’s travel aligns with your riding preferences and frame geometry.

Conclusion

Tuning your RockShox ZEB Select+ suspension fork is key to unlocking its full potential. Proper installation, frequent maintenance, and fine-tuning of air pressure, rebound, and compression settings will ensure optimal performance on every ride. By addressing common issues promptly and making the right adjustments based on your riding style, you can enjoy a smoother, more controlled experience, whether you’re tackling aggressive downhill descents or challenging enduro trails.
