Installation of the Fox 36 Performance Elite
Installing the Fox 36 Performance Elite requires precision and attention to detail. Begin by ensuring compatibility with your bike’s headtube and axle standards.
Cut the steerer tube to the appropriate length, accounting for spacers and stem height. Install the star nut or use a threaded insert for carbon steerers. Apply a light coat of suspension grease on the steerer before inserting it into the headtube.
Align the fork crown with the downtube and torque the stem bolts to specification (typically 5–6 Nm). Install the front wheel into the 15×110 mm Boost thru-axle dropouts, and ensure the floating axle is fully engaged and torqued to 19 Nm.
The brake caliper mount follows the Post Mount standard. Align the caliper over the rotor, tighten the bolts to 6–8 Nm, and check for rotor drag. Lastly, zip-tie or route the brake hose and any remote control cables securely along the fork leg.
Adjusting the Suspension Settings
The Fox 36 Performance Elite uses the GRIP2 damper, offering high- and low-speed compression and rebound adjustments. These settings allow riders to tailor performance to terrain and rider weight.
Start by setting sag. Inflate the EVOL air spring using a shock pump to achieve 20–30% sag based on your riding preference. Use Fox’s pressure chart as a baseline, but refine based on test rides.
Use the external dials to fine-tune:
- Low-speed compression (top right dial): Reduces fork dive and brake-induced compression.
- High-speed compression (larger knob under the low-speed): Controls big-hit absorption.
- Rebound adjustments (bottom of right leg): Red dial for low-speed and black knob for high-speed rebound, ensuring traction and minimizing bounce.
Adjust in small increments, typically one click at a time, and test after each change. The Performance Elite’s independent damper circuits give you precise control over ride characteristics.
Routine Maintenance Procedures
Proper upkeep ensures longevity and consistent performance. Fox recommends a lower leg service every 50 hours and a full damper service every 125 hours.
For the lower leg service:
- Remove the air pressure completely.
- Unscrew and remove the lower leg bolts.
- Slide off the lowers carefully; catch any residual oil.
- Clean the stanchions and lower legs with isopropyl alcohol.
- Replace dust wipers and foam rings if worn.
- Add the correct amount of suspension fluid (Fox recommends 20 cc of Float Fluid per leg).
- Reinstall lowers and torque bolts to specification.
For damper or air spring services, Fox’s factory tools and a controlled workshop environment are required. If in doubt, consult a certified service center.
Troubleshooting Common Setup Issues
Several performance issues can arise if the fork isn’t set up correctly.
Harsh ride or excessive feedback: May result from overinflation or too much high-speed compression damping. Lower the pressure or reduce compression clicks.
Fork diving under braking: Usually indicates inadequate low-speed compression. Increase the low-speed compression damping slightly.
Poor small bump compliance: Often due to low-speed rebound set too fast. Increase rebound damping to improve traction.
Full travel not achieved: This may mean too much air pressure or volume spacers. Remove one volume spacer to allow more progression if needed.
Always perform bounce tests and sag checks after each change to confirm improvement.
Customization and Performance Optimization
The Fox 36 Performance Elite allows for tuning using volume spacers. Riders can change the spring curve by adding or removing spacers in the air chamber. More spacers make the fork more progressive, ideal for aggressive riding. Fewer spacers create a more linear feel, suited to flowy trails.
Upgrade options include replacing the GRIP2 damper with a Factory-series damper if desired, although it’s rarely needed due to the high performance of the stock GRIP2. You can also pair it with a remote lockout for marathon racing, although not standard on the 36.
Tire clearance is generous, allowing for up to 2.6″ tires depending on the rim profile. This opens opportunities for experimenting with different wheel setups.
Compatibility With Drivetrain and Frame Standards
The 36 Performance Elite uses a Boost 110 mm spacing, which is compatible with most modern trail and enduro frames. The steerer tube is 1 1/8″ to 1.5″ tapered, fitting standard headsets in almost all trail bikes from 2018 onward.
Brake compatibility includes 180 mm post mount, with adapters available for 200 mm rotors. The fork also supports both 27.5″ and 29″ wheels, depending on the model. Make sure to verify the axle-to-crown measurement to maintain proper geometry.
It is also e-bike rated, meaning it is suitable for heavier builds without compromising structural integrity.
Comparison With Similar Models
When compared to the Fox 36 Factory, the Performance Elite shares the same chassis and GRIP2 damper but lacks the Kashima coating. This results in slightly more stiction, though real-world differences are minimal after proper break-in.
Compared to the Fox 34 Performance, the 36 offers significantly more stiffness and travel range (150–170 mm), making it more suitable for aggressive trails and enduro racing. The RockShox Lyrik Ultimate is a close competitor, offering similar adjustability with the Charger 3 damper, but many riders prefer the support and feel of Fox’s EVOL air spring.
The Performance Elite balances top-tier performance with value, making it a top choice for serious riders who demand reliability and tunability.
FAQs
1. What’s the difference between the Fox 36 Performance Elite and Factory?
The Factory version includes a Kashima-coated stanchion and identical internals. Performance Elite has a black anodized finish but uses the same GRIP2 damper and EVOL air spring.
2. Can I install the 36 Performance Elite on an e-bike?
Yes, it is e-bike rated and fully compatible with modern e-MTB frames and standards.
3. How often should I service my Fox 36 Performance Elite?
Lower leg service is recommended every 50 riding hours, while full damper and air spring service should be done every 125 hours.
4. What volume spacers come pre-installed?
Most 160 mm travel forks include 2 volume spacers. Check inside the air spring for confirmation.
5. Can I use the fork with 27.5” and 29” wheels?
Yes, but you must use the correct version designed for your wheel size. Swapping wheels without checking axle-to-crown height may affect geometry.
6. Is the GRIP2 damper hard to tune?
While advanced, it is user-friendly once you understand each dial. Small adjustments make a big difference, so tune gradually.
Conclusion
The Fox 36 Performance Elite is a high-end suspension fork designed for serious trail and enduro riders. With its precise damper controls, tunable air spring, and robust chassis, it delivers consistent performance on demanding terrain. Its versatility, ease of maintenance, and compatibility with modern standards make it a leading choice for riders looking to optimize their suspension without the price premium of the Factory line.
