A Beginner’s Guide to Tuning 36 Performance Elite Suspension Forks

The Fox 36 Performance Elite suspension fork is a premium choice among riders who demand control, stability, and adjustability on challenging terrain. With its robust chassis, FIT GRIP2 damper, and extensive tuning capabilities, this fork offers high-end performance without the Factory series’ Kashima coating. This guide focuses on properly installing, adjusting, and maintaining the Fox 36 Performance Elite, ensuring compatibility, optimizing performance, and resolving common setup issues.

Tools Required

  • 6mm and 5mm Allen wrenches [paid link]
  • Torque wrench [paid link] (2-24 Nm range)
  • Shock pump
  • Suspension grease and isopropyl alcohol
  • 34mm socket (for air cap removal)
  • Fox-specific volume spacers
  • Clean lint-free cloths

Installation of the 36 Performance Elite

Installing the Fox 36 Performance Elite involves more than simply mounting it to your frame. Proper installation ensures maximum performance and longevity.

Start by cutting the steerer tube to the correct length. Use a cutting guide and a sharp saw to achieve a clean edge. After installing the star nut and crown race, slide the fork into the head tube, ensuring a snug fit with your headset components. Tighten the stem bolts incrementally, aligning the handlebars precisely before final torquing.

Attach the brake caliper to the appropriate post mounts, ensuring compatibility with the rotor size. Fox 36 forks commonly support 180mm rotors without adapters, but check your exact model specifications. Ensure the axle is properly torqued to 19 Nm, and always confirm rotor clearance and caliper alignment before trail use.

Initial Suspension Setup

Correct initial setup of air pressure and sag is crucial for optimal fork behavior. The Fox 36 Performance Elite uses an air spring located in the left leg. Inflate it using a shock pump according to Fox’s rider weight chart, which provides a baseline for sag between 15-20% of total travel.

To check sag, wear full riding gear, mount the bike, and assume a neutral riding stance. Bounce slightly and let the fork settle. The sag indicator o-ring should rest at the recommended percentage of the stanchion length. Adjust air pressure accordingly until proper sag is achieved.

Adjusting Rebound and Compression Damping

The GRIP2 damper on the Performance Elite allows independent high- and low-speed rebound and compression adjustment. This level of control allows fine-tuning for different terrain and rider preferences.

Start with Fox’s baseline clicker settings. For low-speed compression and rebound, turn the knobs fully clockwise (closed) then count clicks counter-clockwise to the recommended setting. Do the same for high-speed adjusters, usually using a 3mm Allen key. Adjust in small increments and test ride between changes. Low-speed rebound controls the fork’s behavior over small bumps and rider input, while high-speed settings affect performance on rapid impacts like roots or drops.

Volume Spacer Adjustment

Volume spacers inside the air spring chamber change the fork’s air spring curve. Adding spacers makes the fork ramp up more quickly, ideal for aggressive riders or those seeking more bottom-out resistance. Removing spacers makes the fork feel more linear and plush.

To adjust, deflate the air spring fully, then remove the air cap using a 34mm socket. Carefully unscrew the top cap and install or remove spacers as needed. Never exceed the maximum number of spacers specified by Fox. Reinstall the cap, inflate to the correct pressure, and check sag again.

Routine Maintenance Schedule

Regular maintenance keeps the Performance Elite operating smoothly. Fox recommends lower leg service every 30-50 hours of ride time and a full damper service every 125 hours.

For the lower leg service, remove the air pressure, then use a soft mallet to gently tap the lower legs free after removing the bottom bolts. Drain old oil and clean all internals with isopropyl alcohol. Apply new suspension grease on seals and reinstall with fresh oil according to manufacturer specs. Always torque bolts to recommended values.

Troubleshooting Common Issues

Common issues often stem from incorrect air pressure, rebound settings, or lack of maintenance. Excessive diving during braking typically results from low air pressure or insufficient low-speed compression damping. Harshness over small bumps can be alleviated by reducing high-speed compression or removing a volume spacer.

If the fork makes knocking noises or feels sticky, inspect for bushing wear or dried-out seals. Address these promptly, as continuing to ride in this state may damage the internals.

Performance Optimization Tips

To further optimize the Performance Elite, consider your terrain and riding style. For trail riding, a more plush setup with lower compression damping may enhance comfort and grip. Enduro riders may benefit from a firmer, more supportive tune using added volume spacers and higher low-speed compression settings.

Recording your settings in a suspension log allows you to track performance changes. Note conditions and impressions after each ride, then tweak settings to find the optimal balance.

Compatibility with Other Components

The Fox 36 Performance Elite is compatible with both 27.5” and 29” wheels, depending on the specific model. Ensure your fork offset matches your bike’s geometry needs, especially with modern slack head angles.

It supports both 15×110 Boost and standard 15×100 hub widths, though axle type must match. Check rotor compatibility, as the fork uses post mounts that may require adapters for non-standard sizes. It works best with modern 1.5” tapered head tubes and requires a crown race matching your headset.

Comparing the Fox 36 Performance Elite to Similar Models

Compared to the Fox 36 Factory, the Performance Elite offers nearly identical internals without the Kashima-coated stanchions. This makes it more affordable with only marginal differences in stiction and wear resistance.

Versus the Fox 34, the 36 offers greater stiffness and travel, making it ideal for aggressive trail and enduro use. Riders focused on climbing efficiency may prefer the lighter 34, while downhill-focused riders will value the 36’s superior control.

RockShox Lyrik is the closest competitor. While both offer similar adjustability and stiffness, personal preference in damper feel often decides between the two. The Lyrik’s Charger damper feels more linear, while the GRIP2 in the Fox 36 offers sharper control with more external tuning options.

FAQs

1. How often should I service my Fox 36 Performance Elite fork?
Routine lower leg maintenance is recommended every 30-50 hours, with full damper service every 125 hours.

2. Can I install the 36 Performance Elite on any mountain bike?
You need to ensure head tube compatibility (1.5” tapered), axle size (Boost or non-Boost), and correct wheel size. Always check your frame’s specifications.

3. Why is my fork harsh over small bumps?
This is typically due to too much high-speed compression or excessive air pressure. Reducing either can improve small bump sensitivity.

4. What’s the benefit of volume spacers in this fork?
Volume spacers allow you to tune the air spring curve. More spacers increase progression and bottom-out resistance, while fewer make the fork feel more linear.

5. How do I know if my rebound is set correctly?
Improper rebound can cause the fork to pack down or bounce excessively. Dial in settings based on terrain, then test ride and adjust accordingly.

6. What’s the difference between the Performance Elite and Factory models?
The primary difference is the stanchion coating—Performance Elite uses black anodized aluminum, while Factory models have a gold Kashima coating for improved durability and lower friction.

Conclusion

The Fox 36 Performance Elite is a highly capable suspension fork offering near-Factory performance in a more affordable package. By understanding its setup, tuning, and maintenance requirements, riders can unlock its full potential across varied trail conditions. Consistent care and thoughtful adjustments will ensure smooth performance and confidence on every ride.
