Installation and Setup of the ZEB Select+

Installing your ZEB Select+ fork is a straightforward process, but it requires attention to detail for proper setup. Follow these steps to install your fork:

1. Prepare the Bike Frame: Begin by removing your old fork from the bike. Ensure that your frame’s head tube is clean and free from any old grease or debris.
2. Install the Fork: Slide the ZEB Select+ into the head tube of the bike. Ensure the fork’s steerer tube is cut to the correct length for your frame. Tighten the headset and fork clamp bolts to the recommended torque specification.
3. Install the Front Wheel: Place the front wheel into the fork dropouts and secure the axle. Tighten it to the manufacturer’s recommended torque.
4. Set the Sag: Using a shock pump, adjust the air pressure in the fork’s air spring. The recommended air pressure will depend on your weight, riding style, and intended use. Ensure that you set the sag properly, which is typically around 20-30% of the fork’s total travel.
5. Install the Brake Caliper: If your fork has mounting posts for disc brakes, install the brake caliper by securing it with the proper bolts and torquing them correctly.
6. Test the Suspension: After installation, compress the fork a few times to ensure everything is functioning correctly. Check for any unusual noises or issues.

Adjusting the ZEB Select+ for Optimal Performance

The ZEB Select+ fork features adjustable rebound and compression damping, as well as an adjustable air spring. To optimize performance, it is crucial to properly tune these settings to match your riding style and terrain.

Rebound Adjustment

Rebound controls the speed at which the fork returns to its full extension after compressing. If the rebound is too fast, the fork will spring back quickly, potentially leading to instability. If it is too slow, the fork may feel sluggish.

• Turn the rebound knob located on the bottom of the fork leg.
• Turn it clockwise to slow down the rebound.
• Turn it counterclockwise to speed up the rebound.
• Test the fork’s response by compressing it and letting it return to full extension.

Compression Adjustment

Compression damping controls the fork’s resistance to compression during impacts. A well-adjusted compression setting ensures that the fork absorbs hits efficiently without bottoming out or feeling too stiff.

• The ZEB Select+ fork typically features low-speed compression adjustment.
• Adjust the compression dial to the desired setting.
• For trail riding, start with the setting at around halfway and fine-tune based on terrain and feedback.

Air Spring Adjustment

The air spring in the ZEB Select+ fork allows for fine-tuning of the suspension’s progression. By adjusting the air pressure, you can change how the fork responds to various impacts.

• Use a shock pump to adjust the air pressure.
• Start with the recommended air pressure for your weight and fine-tune based on your riding experience.

Regular Maintenance and Care

To ensure the longevity and performance of your ZEB Select+ fork, regular maintenance is necessary. Here’s a comprehensive maintenance schedule:

Cleaning the Fork

Keeping your fork clean is one of the simplest and most effective ways to maintain its performance.

• After every ride, wipe down the fork with a clean rag to remove dirt and debris.
• Focus on the stanchions and seals, ensuring they remain free of grit that could cause wear.
• Use a suspension-specific cleaner for a deeper clean when necessary.

Changing the Oil

Over time, the fork’s damping fluid can degrade, reducing performance. Regular oil changes will ensure smooth operation and prevent internal damage.

• To change the oil, remove the fork from the bike and take off the lower legs.
• Drain the old oil and replace it with fresh oil of the recommended type and quantity.
• Ensure that you properly lubricate the fork seals to prevent leakage.

Fork Seals Maintenance

The seals on the ZEB Select+ are critical for keeping contaminants out and maintaining the fork’s oil levels. Check the seals for wear and replace them if necessary.

• Remove the fork lowers and clean the seals.
• If there is excessive wear or oil leakage, replace the seals.
• Lubricate the new seals with suspension grease before reinstalling them.

Troubleshooting Common Issues

Fork Feel Too Soft or Too Stiff

If the fork feels too soft or too stiff, it may be a result of improper air pressure or damping settings.

• Solution: Adjust the air pressure in the air spring for better support. For a stiffer feel, increase air pressure; for a softer feel, decrease it. Similarly, adjust the compression damping to suit the terrain.

Fork Bottoming Out

If the fork is bottoming out frequently, the air spring pressure may be too low, or the rebound damping could be set incorrectly.

• Solution: Increase the air pressure to reduce bottoming out. Additionally, adjust the rebound setting to ensure proper extension after each compression.

Noisy Suspension

A noisy fork is usually a sign of contamination or insufficient lubrication in the seals or stanchions.

• Solution: Clean the fork thoroughly and lubricate the seals. Ensure that there is no grit or dirt around the stanchions.

Customization and Optimization

The ZEB Select+ fork is highly customizable to meet specific rider preferences. Here are some tips for optimal performance:

• Tune the Air Pressure: Adjust the air pressure based on your weight and riding style. For aggressive riders, slightly higher air pressure can improve support and reduce bottoming out. For smoother rides, lower pressures may provide better comfort.
• Adjust Damping: Fine-tuning both low-speed compression and rebound settings can significantly change how the fork performs in different conditions. For example, softer compression damping is ideal for smoother trails, while firmer damping can help handle rougher terrain.
• Upgrade the Seals: If you’re looking for even smoother performance, consider upgrading to high-end seals for less friction and more consistent performance over time.

Compatibility with Other Drivetrain Components

When installing or upgrading the ZEB Select+, it is important to ensure that it is compatible with your bike’s drivetrain and frame.

• Headset and Fork Length: The ZEB Select+ typically comes with a steerer tube length of 1.5” tapered, so check your frame for compatibility. Additionally, the fork’s axle-to-crown measurement should be matched to your bike’s intended geometry.
• Brake Mounts: The ZEB Select+ features a post mount brake configuration. Be sure to use the correct adapters for your brake calipers.
• Axle Compatibility: The fork is compatible with a 15mm or 20mm thru-axle, depending on your frame’s requirements. Always check for proper axle sizing.

Conclusion

The ZEB Select+ fork from RockShox is a durable, high-performance suspension fork that can enhance your riding experience with proper care and maintenance. By following the installation steps, fine-tuning the adjustments, and staying on top of regular maintenance, you can ensure your fork operates at its peak for years to come. Whether you’re a seasoned rider or just starting, this guide will help you keep your ZEB Select+ fork in optimal condition, ready for your next adventure.
