The RockShox ZEB Select+ suspension fork is a popular choice for aggressive riders seeking a durable and high-performance fork for enduro and downhill biking. With its robust chassis and customizable damping system, the ZEB Select+ offers exceptional performance on challenging trails. However, to get the most out of this fork, proper tuning is essential. This guide will walk you through the installation, adjustment, maintenance, troubleshooting, and optimization of your ZEB Select+ to enhance its performance.

Installation of ZEB Select+ Suspension Fork

Installing the RockShox ZEB Select+ suspension fork requires precision to ensure optimal performance. Here’s a step-by-step guide for a smooth installation.

Step-by-Step Installation

  1. Remove the Old Fork: If you’re replacing an old fork, begin by loosening the axle and stem bolts. Detach any cables or accessories connected to the old fork.
  2. Install the New ZEB Select+: Slide the fork into your bike’s head tube, ensuring that it is centered and aligned properly.
  3. Attach the Stem: Tighten the stem bolts evenly to ensure the fork’s steerer tube sits at the correct height. Double-check the headset bearings to ensure they are correctly installed.
  4. Install the Axle: Slide the axle through the dropouts of the fork and tighten it securely. Ensure the axle aligns correctly with the wheel.
  5. Check Alignment: After installation, ensure that the fork is aligned with the front wheel and handlebars for a true setup.

Tools Required for Installation:

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

Adjusting ZEB Select+ Suspension Forks

The ZEB Select+ is known for its wide range of adjustability, allowing you to customize the suspension to suit your riding style and the terrain you’re tackling. Here are the key adjustments:

1. Rebound Adjustment

Rebound controls how quickly the fork returns after compression. Getting this right ensures the fork doesn’t rebound too quickly or too slowly, giving you optimal control on the trail.

  • To Adjust: Turn the rebound knob at the bottom of the right fork leg. Turning it clockwise slows down the rebound, while counterclockwise speeds it up.
  • Tips: Start with a neutral rebound setting, then adjust based on terrain. For smoother trails, you may want faster rebound; for rougher terrain, a slower rebound is recommended.

2. Compression Adjustment

Compression controls how the fork reacts when it hits an obstacle. The ZEB Select+ features both high-speed and low-speed compression adjusters.

  • Low-Speed Compression: Located at the top of the left fork leg, this knob adjusts fork stiffness. Turning it clockwise increases compression (firmer fork), while counterclockwise makes it softer (better for rough terrain).
  • High-Speed Compression: This adjuster fine-tunes the fork’s response to big hits or fast terrain. It’s ideal for aggressive riding or riding over rough surfaces.

3. Air Pressure Adjustment

Air pressure in the fork’s air spring impacts the overall feel of the fork. Too much air pressure can make the fork stiff, while too little pressure can lead to bottoming out.

  • To Adjust: Use a shock pump to add or release air from the air spring. Follow the manufacturer’s recommended air pressure guidelines for your weight and riding style.
  • Tips: Set the pressure so that the fork sags around 20-30% of its total travel when you’re on the bike. This provides ideal suspension performance.

Maintenance of ZEB Select+ Suspension Fork

Regular maintenance is essential to keep your ZEB Select+ fork running smoothly for years. Below are some basic maintenance tips:

1. Cleaning

After every ride, wipe down the fork with a damp cloth to remove dirt and debris from the stanchions. Keeping the fork clean prevents dirt from damaging the seals.

2. Lubing the Seals

Lubricating the seals ensures that they remain supple and prevents wear and tear. Apply a thin layer of suspension grease or oil to the stanchions after cleaning the fork.

3. Fork Oil Changes

Fork oil degrades over time and can affect performance. Change the fork oil regularly to maintain optimal damping performance.

  • To Change Fork Oil: Remove the fork, disassemble the lowers, drain the old oil, and refill with fresh suspension oil. Be sure to follow the manufacturer’s recommended oil type and quantity.

4. Spring Maintenance

If your ZEB Select+ uses a coil spring, regularly inspect it for signs of damage or wear. Coil springs should be lubricated occasionally for smooth operation.

Troubleshooting Common Issues with ZEB Select+

Common problems with the ZEB Select+ suspension fork can often be fixed with simple adjustments. Here are some issues you might encounter:

1. Fork Bottoming Out

If your fork bottoms out frequently, it might 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. Make sure your sag is set correctly.

2. Lack of Rebound Control

If the fork feels sluggish or bounces excessively, the rebound adjustment might be incorrect, or there could be an issue with the fork oil.

  • Solution: Adjust the rebound setting to make it faster or slower, depending on the issue. If the problem persists, change the fork oil.

3. Noisy Fork

Squeaks or knocking sounds often occur due to dirt, debris, or damaged seals.

  • Solution: Clean the stanchions and inspect the seals for damage. Lubricate the seals and stanchions if necessary.

Customizing and Optimizing ZEB Select+ for Better Performance

Fine-tuning your ZEB Select+ can significantly enhance your riding experience. Here’s how to optimize it for different scenarios:

1. Tuning for Different Terrain

The ZEB Select+ is a versatile fork and can be tuned for various types of terrain:

  • Smooth Trails: For smoother terrain, set a firmer fork with less rebound for better pedaling efficiency.
  • Aggressive Downhill Riding: For downhill riding, soften the fork to make it more responsive and slow down the rebound to control big hits.

2. Adjusting for Rider Weight

Your body weight plays a significant role in how the fork performs. Heavier riders will need to run higher air pressure to prevent bottoming out, while lighter riders should reduce the air pressure for the right sag and performance.

ZEB Select+ vs. Other Suspension Fork Models

Comparing the ZEB Select+ to other popular suspension forks, such as the RockShox Lyrik and Fox 36, highlights the strengths of each:

  • ZEB Select+: Known for its stiff chassis and high adjustability, ideal for aggressive enduro and downhill riding. It’s heavier than some alternatives but offers superior performance in tough conditions.
  • Lyrik: Lighter and more suitable for all-mountain riding but offers less stiffness compared to the ZEB.
  • Fox 36: Comparable to the ZEB in terms of performance, but the Fox 36 is considered more tunable for cross-country and trail riding.

Compatibility with Other Drivetrain Components

The ZEB Select+ is compatible with most modern drivetrain systems, as it uses a standard 15mm or 20mm thru-axle. Ensure your bike frame is compatible with the fork’s travel and steerer tube diameter for a smooth installation.

Conclusion

Tuning your RockShox ZEB Select+ suspension fork is essential for unlocking its full potential. Proper installation, regular maintenance, and thoughtful adjustment of air pressure, rebound, and compression settings will ensure the fork performs optimally. By addressing common issues and tailoring your setup to your riding style, you’ll enjoy a smoother, more controlled ride, whether you’re hitting aggressive downhill sections or navigating challenging enduro trails.
