The Fox 36 Factory GRIP2 suspension fork is designed for aggressive trail and enduro riding, delivering high-end adjustability, support, and damping performance. With its robust chassis, advanced damper, and customization options, it is favored by riders seeking maximum control and tuning flexibility. This guide explores every aspect of the 36 Factory GRIP2 fork, from installation and tuning to maintenance and performance optimization.
Tools Required:
- Torque wrench [paid link] (Nm-specific)
- 6mm and 8mm hex keys [paid link]
- Shock pump (for air spring adjustment)
- 2.5mm and 3mm hex wrenches (for adjusters)
- Suspension oil and grease (Fox-approved)
- Clean workspace and rags
Installation of the Fox 36 Factory GRIP2 Fork
Installing the 36 Factory GRIP2 requires attention to detail to ensure safety and functionality. Begin by verifying headset compatibility and cutting the steerer tube to length if necessary. Always install a star nut or compression plug before tightening the stem.
Secure the fork into the headset, ensuring even compression of the bearings. Tighten the stem bolts to Fox’s recommended torque values. Ensure the front wheel is correctly aligned with the dropouts and the axle is torqued to specification. Before riding, check that all bolts are tightened, and cables are routed cleanly to avoid interference.
Adjusting the GRIP2 Damper for Performance
The GRIP2 damper is the heart of this fork’s performance, featuring independent high- and low-speed compression and rebound circuits. Start by setting the air spring pressure according to your rider weight and sag preference (typically 20–30%).
Next, adjust rebound with the red dial at the bottom of the right fork leg. Fine-tune low-speed rebound first, then high-speed, which controls response to rapid impacts. Use the blue and black knobs on the top of the right fork leg to dial in low-speed and high-speed compression. These controls affect how the fork responds to pedaling forces, brake dive, and large hits.
Routine Maintenance Procedures
To maintain peak performance, service intervals must be followed precisely. Fox recommends a lower leg service every 50 hours and a full damper service every 125 hours of ride time.
Lower leg maintenance includes cleaning and lubricating the stanchions, replacing dust wipers and foam rings, and refreshing bath oil. A full damper service requires disassembly of the GRIP2 cartridge and bleeding the circuits. For this, Fox recommends using its proprietary tools or seeking professional service if you lack experience.
Regularly inspect seals, check for oil weeping, and clean the stanchions after every ride. Avoid pressure washers as they can force dirt into seals.
Troubleshooting Common Setup Issues
If the fork feels harsh or lacks mid-stroke support, reassess air pressure and compression damping. Inadequate sag or excessive high-speed compression can cause harshness. Conversely, if the fork feels too soft or dives under braking, increase air pressure or adjust low-speed compression.
Clicking or knocking noises often result from loose axle hardware or worn bushings. Inspect all mounting points and retighten to specification. If damping feels inconsistent, air might have entered the damper circuit—a full damper bleed is required.
Fork binding or reduced travel usually points to over-tightened pinch bolts or misaligned front axles. Loosen axle hardware, compress the fork fully, and re-torque to spec.
Customization and Performance Optimization
The 36 Factory GRIP2 is highly tunable. Volume spacers in the air spring can be adjusted to change spring progression. Adding spacers increases end-stroke support, ideal for aggressive riders or jump-heavy terrain.
For riders who want a firmer platform while climbing, adjusting the low-speed compression can reduce unwanted motion. Additionally, external rebound adjustments allow you to sync fork behavior with rear shock dynamics, improving overall bike balance.
Fox also offers optional axle inserts and bolt-on fenders that integrate with the arch, reducing clutter and improving aesthetic appeal.
Comparison with Similar Fork Models
Compared to the 36 Performance Elite, the Factory version offers a Kashima-coated stanchion for enhanced durability and smoother action. The Performance Elite shares the same chassis and damper but lacks the coating and polished finish.
The 38 Factory GRIP2 is stiffer and designed for heavier riders or more extreme terrain. However, it adds weight and may feel overbuilt for general trail riding. The 34 Factory, on the other hand, is lighter but lacks the stiffness and tuning range of the 36.
Thus, the 36 Factory GRIP2 sits in the ideal performance zone for aggressive trail and enduro riders who need a balance of stiffness, travel, and fine-tune control.
Compatibility with Other Drivetrain and Frame Components
The 36 Factory GRIP2 fork is compatible with a wide range of frame standards, typically designed for 29-inch wheels and 110mm Boost spacing. It works seamlessly with modern trail and enduro frames that accept tapered steerer tubes.
Ensure rotor size compatibility—Fox allows up to 203mm rotors using appropriate adapters. The fork integrates well with both SRAM and Shimano braking systems.
While the fork doesn’t interface directly with drivetrain components, proper fork setup (including axle-to-crown height and offset) impacts overall bike geometry and handling, indirectly influencing drivetrain efficiency and rider comfort.
Frequently Asked Questions
How much travel does the 36 Factory GRIP2 offer?
It comes in travel options ranging from 150mm to 170mm, depending on the model and chassis.
Can I reduce or increase travel on the fork?
Yes, travel can be adjusted internally by changing the air spring assembly. This should be done following Fox’s service manual or by a certified technician.
What tire clearance does it support?
The fork allows clearance for up to 2.6” tires on 29” rims, depending on tread pattern and rim width.
How do I know when to service the fork?
Signs include reduced small bump sensitivity, oil seepage from seals, or a noisy damper. Always follow the recommended 50-hour lower leg service interval.
Is the GRIP2 damper user-serviceable?
It is serviceable, but due to complexity, Fox recommends professional service unless the user is experienced with damper internals.
Can I install a fender on this fork?
Yes, Fox offers a bolt-on fender designed specifically for the 36 Factory, using the arch-mounted screw holes.
