  • 10mm Allen wrench [paid link]
  • Torque wrench [paid link]
  • Suspension oil (recommended for ZEB Select+)
  • Suspension grease
  • Plastic pry tools
  • Clean rags
  • Air pump (compatible with RockShox forks)
  • Clean basin or container
  • Snap ring pliers
  • Stanchion protectors (optional)

Step 1: Preparation and Safety

Before you start servicing your ZEB Select+, ensure you have all the necessary tools and materials ready. Work in a clean and dry area, preferably in a well-lit space with ample room to move around. It’s essential to wear protective gear such as gloves and goggles to avoid injury when handling suspension components.

Make sure the bike is securely positioned, either in a bike stand [paid link] or with the front wheel removed, to ensure easy access to the fork.

Step 2: Remove the Fork from the Bike

  • Use the 8mm Allen wrench to remove the bolts securing the fork to the frame.
  • Carefully remove the front wheel and set it aside.
  • Detach the brake caliper and shifter cables if necessary. Depending on your bike setup, you may need to loosen or remove the brake rotor.
  • Once all components are cleared, gently lift the fork off the frame.

Step 3: Remove the Fork Components

Now that the fork is free from the bike, it’s time to begin disassembling the fork to access the suspension internals.

  • Start by removing the air cap with your 10mm Allen wrench. This step will release any air pressure within the fork.
  • Use a plastic pry tool to carefully separate the fork’s lowers from the stanchions. Be mindful not to scratch the stanchions during this process.
  • Once the lowers are removed, you’ll have access to the damper and air spring internals.

Step 4: Drain and Clean the Fork Internals

With the fork disassembled, it’s time to clean the internal components. Carefully inspect the damper and air spring for any visible signs of wear or damage.

  • Use clean rags to wipe off any grease or dirt from the components.
  • Drain the old suspension oil from the damper and lowers. You can do this by carefully tilting the fork and allowing the oil to pour out into a container.
  • Be thorough in cleaning the internal parts, especially the air spring seals. A build-up of dirt or oil can compromise the fork’s performance.

Step 5: Rebuild the Fork Internals

Once the fork is clean and free from debris, it’s time to reassemble it.

  • Apply a thin layer of suspension grease to the bushings and seals before reassembling the lowers onto the stanchions.
  • Fill the damper with the recommended suspension oil for the ZEB Select+. Follow the manufacturer’s guidelines for the exact amount of oil to use.
  • Carefully insert the air spring and ensure that all parts are correctly seated.

Step 6: Reinstall the Fork Lower Leg Assembly

With the internals rebuilt, it’s time to reattach the lower legs to the stanchions.

  • Carefully slide the lowers back onto the stanchions, making sure they are aligned properly.
  • Use your plastic pry tools if necessary to ensure the legs are fully seated.
  • Reinstall the air cap and use the air pump to add air to the fork. Follow the recommended pressure settings based on your weight and riding style.
  • Reattach the brake caliper and any other components that were removed during disassembly.

Step 7: Set the Correct Air Pressure

The ZEB Select+ fork uses an air spring, and setting the correct air pressure is critical for achieving optimal suspension performance.

  • Use the air pump to inflate the fork to the recommended PSI. RockShox provides a chart with pressure settings based on rider weight, but it can be fine-tuned based on personal preferences and riding conditions.
  • Start with the manufacturer’s recommended setting and adjust accordingly to achieve the desired fork performance.

Step 8: Check and Adjust the Damper Settings

The ZEB Select+ comes with an adjustable damper, which allows you to fine-tune the compression and rebound for a more customized ride. After reinstalling the lowers and setting the air pressure, check the damper settings:

  • Adjust the rebound and compression dials on the fork according to your preferences. For a more controlled ride, tighten the compression. If you prefer a faster rebound, loosen the rebound dial.
  • Ensure that the settings provide the desired balance between comfort and performance, depending on your riding style.

Step 9: Reinstall the Fork on the Bike

After servicing and reassembling your ZEB Select+ fork, reinstall it on the bike.

  • Secure the fork to the frame by tightening the bolts with an 8mm Allen wrench. Make sure the fork is aligned correctly with the frame and fork dropouts.
  • Reinstall the front wheel and check that it is properly centered.
  • Reconnect the brake caliper and shifter cables if needed.

Step 10: Perform a Final Check

Before hitting the trails, perform a final inspection of your suspension fork. Check for any unusual sounds, leaks, or loose parts. Take the bike for a short ride to test the suspension, ensuring everything works smoothly.

Troubleshooting Common ZEB Select+ Issues

While servicing your ZEB Select+ fork, you may encounter a few common issues that can affect performance. Here are some troubleshooting tips:

  • Fork feels too soft or too stiff: This could indicate an incorrect air pressure setting. Adjust the pressure according to your weight and riding style.
  • Suspension feels sluggish or unresponsive: This could be a sign of old or contaminated suspension oil. Drain and replace the oil as described in the maintenance steps.
  • Leaking air or oil: Inspect the seals for damage. Replace any damaged seals and ensure the lowers are properly sealed to the stanchions.

Customization and Optimization

The ZEB Select+ offers a wide range of adjustability to cater to different riding styles. You can customize the performance of your fork by experimenting with different air pressures, damper settings, and fork travel. Whether you ride aggressively or prefer a smoother, more relaxed ride, adjusting these components will allow you to optimize the fork for your needs.

Comparison with Similar Models

When comparing the ZEB Select+ to other suspension forks like the RockShox Lyrik or Fox 36, the ZEB Select+ stands out due to its robust chassis and large stanchions, making it ideal for riders who demand high performance under extreme conditions. While the Lyrik is also known for its durability, the ZEB Select+ offers a more rigid feel, which is preferred by downhill and enduro riders. On the other hand, the Fox 36 offers a slightly smoother ride for cross-country and trail riders but may not offer the same level of support in demanding conditions.

Compatibility with Other Drivetrain Components

The ZEB Select+ suspension fork is compatible with most modern drivetrains, including SRAM and Shimano systems. It is designed to work seamlessly with bikes equipped with 27.5″ or 29″ wheels and offers a wide range of travel options. Before installing the fork, ensure that your bike’s frame is compatible with the ZEB Select+ specifications.
