Installing the Fox 36 Performance Elite
Proper installation of the 36 Performance Elite ensures reliable performance and safety. Begin by verifying head tube compatibility and crown race specifications. The fork uses a tapered steerer and is designed for 110 mm Boost axle spacing.
Ensure the crown race is fully seated on the fork’s steerer before inserting into the head tube. Install the headset spacers and stem, then torque the top cap and stem bolts to manufacturer specs. When aligning the caliper mount, use the proper adapter for rotor size compatibility and torque to specification.
Once the fork is mounted, attach the front wheel and align the thru-axle using Fox’s Kabolt-X or standard QR system. Finalize alignment of the front brake caliper to ensure there’s no rotor rub.
Adjusting the GRIP2 Damper and Air Spring
The 36 Performance Elite uses Fox’s GRIP2 damper with high- and low-speed compression and rebound adjustability. Begin by setting the sag, ideally between 15%–20% of fork travel. Use a shock pump to adjust the air pressure based on rider weight and preferred feel.
For compression settings, dial in low-speed compression to fine-tune support during body movements such as cornering or pumping. Adjust high-speed compression to control how the fork handles large impacts and drops. Rebound settings control how quickly the fork returns after compression—start at the midpoint and fine-tune based on trail feedback.
The GRIP2’s independent adjustment knobs allow for high granularity in tuning. Riders should adjust incrementally and record settings for future reference.
Routine Maintenance Intervals and Procedures
To keep the 36 Performance Elite operating at peak efficiency, follow Fox’s maintenance schedule. Lower leg service is recommended every 30–50 hours of ride time. This includes removing the lower legs, replacing foam rings, and changing bath oil.
For lower leg servicing:
- Remove the front wheel and brake caliper.
- Carefully slide off the lower legs after removing the damper and air shaft bolts.
- Clean out old oil, inspect for debris or wear, and replace wipers and foam rings if needed.
- Reapply Fox 20wt Gold Oil in the lower legs and reassemble.
Full damper and air spring service is advised every 125 hours or annually. These procedures involve full disassembly of the GRIP2 damper and air shaft, which may require specialized tools and training. Sending the fork to a certified Fox service center is recommended for internal damper service.
Troubleshooting Common Issues
If the fork feels harsh or sticks during compression, check for dry wipers or contaminated lower leg oil. Stiction is often caused by a lack of lubrication. For air loss issues, inspect the Schrader valve and check for shaft seal damage. Use a soapy water test to find leaks.
For damping inconsistencies, such as spiking or dead travel zones, consider bleeding the damper or inspecting for air contamination in the oil. A full damper rebuild may be required if rebound or compression settings become ineffective.
Creeking from the crown steerer interface may develop over time. While annoying, this is sometimes related to steerer tube tolerances and may be addressed by regreasing or applying carbon assembly paste to the steerer and crown race interfaces.
Optimizing the 36 Performance Elite for Performance
For more aggressive terrain or enduro racing, adding volume spacers can improve bottom-out resistance and make the fork feel more progressive. The 36 Performance Elite’s EVOL air spring accepts spacers to adjust spring curve response.
Re-tuning rebound and compression based on rider feedback is crucial. Heavier riders may benefit from increased air pressure and slower rebound. Lighter riders can improve comfort by decreasing pressure slightly and softening compression.
For front-end stiffness, consider upgrading to a Kabolt-X axle, which reduces flex under load. Aligning fork performance with terrain and riding style maximizes its capabilities.
Compatibility with Drivetrain and Braking Systems
The 36 Performance Elite fork is designed to work with modern 29-inch or 27.5-inch Boost wheelsets. Its 110 mm spacing supports modern hub standards and allows easy integration with wide-rim trail or enduro wheels.
Brake mounts are Post Mount 180 mm, compatible with most hydraulic disc brakes. Ensure caliper and adapter combinations match your rotor size—203 mm setups are common for enduro use and require the correct adapter for clearance.
Although the fork does not interface directly with drivetrain components, cable routing for 1x drivetrains or electronic systems should be planned to avoid interference with the fork crown and stanchions during compression.
Comparing the 36 Performance Elite with Similar Models
The 36 Performance Elite sits just below the Factory Series in Fox’s hierarchy. While it shares the same GRIP2 damper and chassis as the Factory model, it lacks the Kashima coating. This has minimal impact on performance but slightly affects durability and aesthetics.
Compared to the Fox 34, the 36 offers increased stiffness and better support for aggressive riding. It is significantly more trail-capable and designed to handle sustained high-speed descents and repeated big hits.
When placed against the RockShox Lyrik Ultimate, the 36 Performance Elite holds its ground in terms of adjustability and small bump sensitivity. However, some riders may prefer the slightly more linear feel of the Lyrik’s Charger 3 damper. Ultimately, both forks cater to high-performance trail riders, but the 36 Performance Elite provides more tuning depth and chassis rigidity.
FAQs About the Fox 36 Performance Elite
How often should I service my 36 Performance Elite fork?
Lower leg service is recommended every 30–50 hours, and a full damper/air spring service every 125 hours or annually.
Can I use the 36 Performance Elite with a 27.5-inch front wheel?
Yes, the fork is available in both 27.5-inch and 29-inch versions. Ensure you match wheel size to fork version.
Is the GRIP2 damper difficult to adjust?
No, it offers intuitive dials for high- and low-speed adjustments. Beginners can start at baseline settings and tune incrementally.
How many volume spacers can I add to the air spring?
The fork can accept multiple spacers depending on travel length. Refer to the Fox volume spacer chart for exact limits.
Does the absence of Kashima coating affect performance?
While Kashima reduces friction slightly and improves durability, Performance Elite forks still offer exceptional performance with standard anodizing.
What axle options are available for this fork?
It supports both the standard 15QR and Kabolt-X 110 mm axles, allowing riders to choose based on stiffness and convenience.
