The ZEB Select+ from RockShox is a high-performance suspension fork designed for aggressive mountain biking. Whether you are a seasoned rider or a beginner, proper maintenance is crucial for keeping your suspension fork in optimal working condition. This guide will walk you through the installation, adjustment, maintenance, troubleshooting, customization, and compatibility aspects of the ZEB Select+ to help you get the most out of your ride.

Tools Required

To maintain and adjust your ZEB Select+ suspension fork, you’ll need the following tools:

  • 5mm, 6mm, and 8mm hex wrenches
  • Torque wrench [paid link]
  • Suspension oil (specific to RockShox)
  • T25 Torx wrench [paid link]
  • Clean rags or paper towels
  • Grease for suspension parts
  • RockShox air pump
  • Suspension fluid syringe (for damper maintenance)
  • Cartridge holder tool (if servicing the damper)
  • Bleed kit [paid link] (for air spring and damper bleeding)

Installation of the ZEB Select+

Proper installation of the ZEB Select+ suspension fork is essential for ensuring optimal performance. Follow these steps to install the fork correctly:

  1. Prepare Your Bike: Before you begin, remove the front wheel and the old fork (if applicable). Ensure your headset and frame are clean and ready to accept the new fork.
  2. Install the Headset: Make sure the headset is in good condition and greased for smooth operation.
  3. Mount the Fork: Slide the steerer tube of the ZEB Select+ fork into the headset. Align the fork properly and install the star nut (if not already pre-installed).
  4. Secure the Crown and Stem: Attach the stem to the steerer tube and tighten it to the manufacturer’s torque specifications. Ensure that the stem is aligned correctly to avoid handling issues.
  5. Install the Front Wheel: Reinstall the front wheel into the fork dropouts. Tighten the thru-axle or quick-release skewer securely, ensuring the wheel is centered.
  6. Connect the Brake Mounts: Install the brake caliper onto the fork’s post-mounts and secure it with the appropriate fasteners. Torque the bolts to the recommended values.
  7. Check Alignment: Finally, check that the fork is aligned straight with the frame and that the handlebars turn freely without obstruction.

Adjustment of the ZEB Select+

To ensure your ZEB Select+ suspension fork is tuned to your preferences, you’ll need to make several adjustments. These will affect how the fork absorbs impacts and responds to different terrain. Here’s a guide to making those adjustments:

Air Spring Pressure

The ZEB Select+ uses a coil-sprung system for better stability and control. Adjusting the air pressure in the air spring is vital to ensure the correct balance for your riding style.

  • Find the correct pressure: Use a RockShox air pump to adjust the air pressure. Start with the recommended air pressure based on your weight, and make small adjustments from there.
  • Check sag: To check the sag, measure the amount of travel your fork uses under your body weight. Aim for 15-25% sag for aggressive riders and 25-30% for more casual riding.

Compression and Rebound Settings

The ZEB Select+ fork features adjustable compression and rebound damping to fine-tune performance for different trails and conditions.

  • Compression: Adjust the compression dial to control how the fork responds to bumps and landings. A firmer compression setting is ideal for smoother trails, while a softer setting is better for technical terrain with lots of obstacles.
  • Rebound: Adjust the rebound setting to control how quickly the fork returns after compressing. Faster rebound helps to keep the fork active and responsive, while slower rebound adds stability.

Damper Settings

The ZEB Select+ includes the Charger 3 damper, which provides exceptional control and adjustability.

  • Open Mode: For rough terrain, set the damper to “open mode,” allowing full compression travel. This provides maximum comfort and control on technical descents.
  • Firm Mode: For climbing or smoother terrain, engage the firm mode to prevent excessive bobbing and improve efficiency.

Maintenance of the ZEB Select+

Regular maintenance is key to keeping the ZEB Select+ performing at its best. Below are essential maintenance tasks that you should perform to prolong the life of your suspension fork:

Cleaning and Lubing the Fork

  • Regular Cleaning: After every ride, clean the stanchions with a rag to remove dirt and grime. A clean fork is essential to maintaining smooth travel and preventing wear on seals.
  • Lubrication: Apply suspension-specific grease to the stanchions periodically to ensure smooth sliding of the fork legs and prevent corrosion.

Service Intervals

  • Lower Leg Service: The ZEB Select+ requires lower leg service approximately every 50 hours of riding. During this service, remove the lowers, inspect the seals, and replace the suspension fluid if necessary.
  • Damper Service: For optimal performance, the damper should be serviced every 150 hours of riding. This involves removing the damper cartridge, draining old oil, and replacing it with fresh suspension fluid.
  • Full Fork Overhaul: Every 200 hours of riding or once a year, it is recommended to perform a full fork overhaul, including checking for wear on the seals, replacing any worn components, and performing a thorough cleaning of the internals.

Troubleshooting Common Issues

While the ZEB Select+ is a high-quality suspension fork, like all bike components, it can experience some issues. Below are common problems and solutions:

No Suspension Travel or Stiff Fork

  • Cause: This could be due to incorrect air pressure or a malfunctioning damper.
  • Solution: Double-check your air pressure settings. If the fork is still stiff, it may require a damper service or a complete fork overhaul.

Fork Bottoming Out Too Easily

  • Cause: Low air pressure or an incorrectly adjusted compression setting.
  • Solution: Increase air pressure to the recommended level and adjust the compression to suit your riding style. Consider upgrading to a coil spring for improved bottom-out resistance.

Excessive Fork Bounce or Inconsistent Travel

  • Cause: The rebound damping may be too soft, or the fork may need servicing.
  • Solution: Adjust the rebound setting for better control. If the issue persists, perform a lower leg service and check the damper for any internal damage.

Customization and Optimization

The ZEB Select+ can be customized to suit your riding style and preferences. Below are a few ideas for optimizing your fork:

Upgrading to a Coil Spring

If you prefer a more consistent and progressive feel, consider upgrading to a coil spring. The coil offers better small-bump sensitivity and more control on rough trails.

Installing a Larger Air Volume Spacer

For riders who need more support through the mid-stroke, adding a larger air volume spacer can increase the ramp-up of the fork, making it less likely to bottom out on big hits.

Compatibility with Other Drivetrain Components

The ZEB Select+ is designed to work seamlessly with other high-performance drivetrain components. However, compatibility with other components should always be considered to avoid performance issues. Ensure that your fork is properly matched with your bike’s frame and headset specifications for the best experience. Additionally, consider pairing the ZEB Select+ with a RockShox rear shock and high-quality wheels to achieve balanced suspension performance across your entire bike.
