- Suspension pump (Fox-compatible)
- Clean lint-free cloth
- Isopropyl alcohol
- Suspension-specific grease and oil
- Allen key set
- Fox fork service kit (for lower leg maintenance)
Installation Guide
Correct installation is crucial to ensure the Fox 34 AWL operates safely and performs efficiently. Begin by verifying compatibility with your frame and front axle standard.
Preparing the Head Tube and Crown Race
Before installing the fork, ensure the head tube is clean and free from debris. Press in the crown race compatible with your headset. Grease lightly to reduce creaking.
Cutting the Steerer Tube
Measure the appropriate steerer tube length by inserting the fork into the head tube and estimating stack height with spacers and stem. Mark and cut using a guide and pipe cutter. Deburr edges for a flush fit.
Installing the Star Nut and Fork
Insert and seat the star nut using a star nut setter. Apply a thin layer of grease on the steerer before sliding it into the head tube. Align the fork properly, place spacers and stem, and preload the headset by tightening the top cap bolt. Secure stem bolts to the manufacturer’s torque specs.
Attaching the Front Wheel
Install the front thru-axle through the hub and fork dropouts. Torque to specification, ensuring the axle is fully seated and the wheel spins freely without resistance.
Adjusting the Fox 34 AWL for Optimal Performance
Proper suspension tuning enhances ride comfort, traction, and control. The Fox 34 AWL supports air spring adjustment, rebound damping, and compression settings.
Setting Sag and Air Pressure
With your full riding gear on, set sag to approximately 25% of total travel. Attach a suspension pump and inflate to a pressure based on Fox’s rider weight chart. Bounce the bike to equalize pressure, then fine-tune based on ride preference.
Rebound Damping Adjustment
Use the red knob at the fork’s base to set rebound. Slower rebound increases control on technical descents; faster rebound benefits flowy, less technical terrain. Begin in the middle setting and make incremental changes.
Compression and Lockout
The blue knob on top of the right stanchion controls low-speed compression. Set this to a softer setting for trail comfort or firmer for climbing efficiency. The lockout lever can be engaged during road transfers or extended climbs.
Maintenance Schedule and Procedures
Routine maintenance preserves fork performance and prevents internal damage. The Fox 34 AWL benefits from periodic lower leg service and annual full rebuilds.
Lower Leg Service (Every 30–50 Hours)
Remove the front wheel and detach the brake caliper. Release air pressure from the fork. Using appropriate tools, remove lower leg bolts and slide off the lowers. Clean internals with isopropyl alcohol. Replace foam rings and apply suspension-specific oil. Reinstall lowers, torque bolts, and re-pressurize.
Annual Full Service
This includes damper bleed and air spring overhaul. Use Fox’s service guide for part compatibility and torque specifications. This service is best performed by experienced mechanics or authorized service centers.
Troubleshooting Common Set-Up Issues
Harsh Ride Quality
Often caused by excessive air pressure or incorrect compression settings. Recheck sag and reduce pressure slightly. Adjust compression to a softer setting.
Excessive Fork Dive
Occurs when low-speed compression is too soft or air pressure is too low. Add air incrementally and close compression by one or two clicks.
Stiction or Lack of Small Bump Compliance
May result from dry or dirty wiper seals. Perform a lower leg service and lubricate seals properly. Use Fox 20wt Gold or specified lubrication oil.
Unusual Noises
Clunking or squishing sounds usually indicate insufficient oil or air transfer issues. Inspect the fork’s internals during service, ensuring correct oil volumes and clean air transfer pathways.
Customization and Performance Optimization
The Fox 34 AWL offers riders a range of customization options to tailor the fork’s behavior to terrain and riding style.
Volume Spacer Tuning
Adjusting volume spacers in the air chamber changes progression. Adding spacers makes the fork more progressive—ideal for aggressive riders. Removing spacers makes it more linear, enhancing comfort over choppy terrain.
Matching Suspension Feel with Rear Shock
For balanced suspension performance, align the fork’s rebound and compression settings with the rear shock. This promotes consistent tracking and reduces front-rear imbalance during descents.
Upgrade Compatible Accessories
The Fox 34 AWL is compatible with mudguards using dedicated arch mounts. Use original Fox accessories to ensure fit and function.
Compatibility with Other Drivetrain and Brake Systems
The Fox 34 AWL features Boost 110 mm axle spacing and post-mount disc brake compatibility. It supports rotor sizes from 180 mm to 203 mm without adapters. Ensure the fork’s steerer is compatible with the frame’s headset standard, and verify brake hose routing for clean cable management.
The fork is designed to integrate with both mechanical and electronic drivetrains. The axle-to-crown height and rake are optimized for trail geometry, and it pairs well with 29” and 27.5+ wheel sizes.
Comparison with Similar Suspension Forks
When compared to other trail forks in the Fox lineup, such as the 34 Performance or Rhythm series, the AWL offers increased weather sealing, simplified damper architecture, and an affordable price point targeted at e-bike and all-weather riders.
While it lacks the Kashima coating found in higher-end models, the AWL’s anodized stanchions still provide excellent durability. For riders prioritizing rugged reliability over weight savings, the AWL stands as a superior choice.
Frequently Asked Questions (FAQs)
How much sag should I run on the Fox 34 AWL?
Aim for 20–25% sag based on your total system weight. This offers the best balance of comfort and control.
Can I use the Fox 34 AWL on a regular mountain bike, not just an e-bike?
Yes. While optimized for e-bikes, the fork works well on any compatible mountain bike frame.
Is it possible to upgrade the damper in the Fox 34 AWL?
The AWL uses a proprietary damper and is not intended for upgrades to higher-end FIT4 or GRIP2 systems.
What type of oil does the Fox 34 AWL use for lower leg service?
Use Fox 20wt Gold for bath lubrication and 5wt Teflon-infused fluid for damper circuits.
Does the Fox 34 AWL support a remote lockout?
No, the fork only supports on-crown compression adjustments and manual lockout.
What is the maximum rotor size compatible with the Fox 34 AWL?
The fork supports rotors up to 203 mm without the need for additional adapters.
Conclusion
The Fox 34 AWL is a robust suspension fork built for comfort, durability, and versatility across various terrain types and riding conditions. With proper installation, routine maintenance, and smart tuning, this fork delivers performance that belies its price point—making it a valuable upgrade for riders looking to enhance ride quality without breaking the bank.
