The ZEB Select+ from RockShox is a standout in the world of trail bike suspension forks, designed to provide unparalleled performance and durability. With its robust construction, advanced features, and exceptional adjustability, it’s tailored for riders who demand more from their gear. This guide explores the installation, adjustment, maintenance, troubleshooting, and optimization of the ZEB Select+ fork, helping you maximize its performance.

Installation of the ZEB Select+

Installing the ZEB Select+ fork requires careful attention to detail to ensure optimal performance. Here’s a step-by-step breakdown of how to install it properly:

1. Remove the Old Fork
   Begin by removing your existing fork from the bike. Use a 5mm Allen key to detach the fork from the headset and remove the brake caliper from the fork’s post-mount tabs. Once all bolts are undone, pull the fork out of the frame.
2. Prepare the ZEB Select+ Fork
   Before installation, make sure the fork is set to the correct steerer tube length for your frame. If necessary, cut the steerer tube to match your bike’s head tube length, making sure to follow the proper guidelines for cutting.
3. Install the Fork Into the Frame
   Slide the ZEB Select+ into the bike’s head tube, ensuring the headset bearings are properly seated. Secure the fork with the appropriate headset and top cap. Tighten the bolts on the stem and check for any play in the headset.
4. Attach the Brake Caliper
   Reinstall the brake caliper onto the fork’s post-mount tabs. Ensure the caliper is aligned with the rotor, and torque the bolts to the manufacturer’s recommended settings.
5. Check the Torque Settings
   After installation, go over each bolt to confirm that all are properly tightened to the recommended torque specifications. This includes the stem, brake caliper, and the top cap.
6. Test the Fork
   Once everything is in place, perform a quick test to ensure the fork functions smoothly and that no unusual noises or movements occur during the compression or rebound.

Adjustment of the ZEB Select+

The ZEB Select+ offers a variety of adjustments to fine-tune your suspension to match your riding style. Here’s how to adjust the fork for optimal performance:

Air Pressure Adjustment

• Goal: Set the proper sag for your body weight and riding style.
• How: Use the air spring’s air valve to adjust the pressure. A general guideline is to set the fork’s air pressure so that the fork compresses about 20-30% of its total travel when you’re in your riding position.
• Tip: Start by adding air to the fork and checking the sag. If the fork is too firm, reduce air pressure. If it’s too soft, increase the pressure.

Compression and Rebound Damping

• Goal: Control the fork’s response to hits and recovery during rides.
• How: Adjust the low-speed compression and rebound damping via the dials located on the fork’s top caps. The low-speed compression controls how the fork compresses under slower impacts, and the rebound controls how quickly the fork returns to its full extension.
• Tip: Start with the dials set to their midpoint, then fine-tune for comfort. If you’re experiencing harsh bottom-outs, dial in more low-speed compression. If the fork feels too bouncy, adjust the rebound to slow it down.

DebonAir Spring Tuning

• Goal: Fine-tune the fork’s overall feel.
• How: The ZEB Select+ fork uses the DebonAir spring to deliver a more consistent, plush feel throughout the travel. Adjusting the air pressure and experimenting with different settings will help you get the perfect ride.
• Tip: The DebonAir spring is designed to provide a more linear feel throughout the travel, so experiment with the air pressure and compression settings to find your ideal setup.

Maintenance of the ZEB Select+

Regular maintenance is crucial for ensuring your ZEB Select+ continues to perform at its peak. Here’s how to keep your fork in top condition:

Clean the Fork Regularly

• After every ride, wipe down the fork legs and seals with a clean, dry cloth. This will prevent dirt and debris from building up, which can cause damage to the fork’s seals and reduce performance.

Lubricate the Seals

• Periodically, remove the fork’s lowers and apply a light coat of suspension oil to the seals. This helps prevent excessive wear and keeps the fork moving smoothly.

Check for Leaks

• Inspect the fork for any oil leaks, particularly around the damper or air spring. If you notice any leaks, it may be necessary to replace the fork’s seals.

Perform Annual Overhaul

• After about 50-100 hours of riding, an annual service is recommended. This includes disassembling the fork, cleaning all internal components, replacing worn seals, and adding fresh suspension fluid.

Troubleshooting Common Set-Up Issues

While the ZEB Select+ is a high-performance fork, issues can arise during set-up. Below are some common issues and how to address them:

Fork Too Soft or Too Firm

• Cause: Incorrect air pressure or rebound settings.
• Solution: Double-check the air pressure, ensuring it’s within the recommended range for your weight. Adjust the rebound damping if the fork feels too slow to return or too quick.

Noisy Fork

• Cause: Dirt or debris in the seals or insufficient lubrication.
• Solution: Clean the seals and lubricate them regularly to prevent noise. If the noise persists, inspect the fork for any damage.

Lack of Travel

• Cause: Incorrect air spring pressure or an issue with the air spring itself.
• Solution: Ensure that the air pressure is properly set according to your weight. If the issue persists, it may be necessary to inspect or replace the air spring.

Customization and Optimization for Better Performance

To fully optimize your ZEB Select+, consider the following customization options:

Upgrade to the Charger 2.1 Damper

• The ZEB Select+ comes with the Charger 2 damper, but upgrading to the Charger 2.1 damper can provide smoother performance and more adjustability. This damper upgrade enhances the fork’s overall ride feel and responsiveness.

Tuning the Air Spring

• To fine-tune the performance for aggressive riding, experiment with different air spring setups. Increasing the air pressure slightly can improve support for larger impacts, while reducing it provides a softer, more forgiving ride.

Use a Remote Lockout

• Adding a remote lockout to the ZEB Select+ allows you to control the fork’s compression from the handlebars. This is especially useful for riders who want to firm up the suspension on climbs and unlock it for descents.

Comparison with Similar Models

When comparing the ZEB Select+ with other models in RockShox’s lineup, such as the Lyric and the Pike, the ZEB Select+ stands out for its greater travel and sturdier chassis, making it the ideal choice for aggressive trail riders and enduro enthusiasts. It is particularly effective for tackling rougher terrain, providing enhanced stiffness and control.

• ZEB Select+ vs. Lyric: The Lyric is better suited for cross-country or trail riding, with less travel and a lighter build. However, the ZEB Select+ offers superior performance for heavier, more aggressive riding styles.
• ZEB Select+ vs. Pike: The Pike is a versatile fork with a similar damper system but is lighter and has a slightly more refined feel for trail riding. However, the ZEB Select+ excels in durability and stiffness, making it a better choice for enduro and rougher terrain.

Compatibility with Other Drivetrain Components

The ZEB Select+ is compatible with a wide range of bike setups. However, to ensure the best performance, it’s essential to pair it with the right components:

• Headset Compatibility: Ensure that your headset is compatible with the ZEB Select+’s steerer tube dimensions.
• Brake Compatibility: The fork comes with 200mm post-mount brake tabs, allowing compatibility with most modern disc brake systems, but always verify rotor sizes and mounting types before installation.
• Wheel Size: The ZEB Select+ is designed for 27.5-inch and 29-inch wheels, providing versatility depending on your frame’s wheel size compatibility.
