Technical Overview of the 34 Float Factory GRIP2
The 34 Float Factory GRIP2 uses a FLOAT EVOL air spring and a high-end GRIP2 damper, featuring independent high/low-speed compression and rebound adjustments. With a Kashima-coated chassis, it is designed to minimize friction and improve longevity. It’s available in 120–140mm travel options and fits 29-inch wheels with Boost spacing.
This fork targets performance-oriented riders who demand precise damping control, particularly in rough, technical terrain. Its standout feature is the GRIP2 damper, which offers unparalleled tuning options.
Installation Guide
Proper installation of the 34 Float Factory GRIP2 ensures safe operation and optimal performance. Begin by cutting the steerer tube to the correct length. Then press the crown race onto the steerer and install the fork into the head tube with headset spacers and a stem. Use a torque wrench [paid link] to secure the stem bolts to the manufacturer’s specifications.
The front wheel should be mounted using a 15x110mm Boost thru-axle. Make sure the axle is properly aligned and torqued to 10 Nm. After the wheel is secured, check the brake caliper alignment and adjust if necessary.
Suspension Setup and Adjustment
Setting up the 34 Float Factory GRIP2 requires balancing air pressure and damper settings. Begin with your rider weight and Fox’s recommended air pressure chart. Adjust the air pressure using a shock pump until the desired sag—typically 20-25%—is achieved.
The GRIP2 damper allows for independent tuning:
- High-speed compression: Controls harsh impact resistance. Start with 6 clicks from fully closed.
- Low-speed compression: Manages body movement and brake dive. Begin at 8 clicks.
- High-speed rebound: Affects recovery from big hits. Start at 6 clicks.
- Low-speed rebound: Controls return speed over smaller terrain. Begin at 10 clicks.
Fine-tune over multiple rides to match terrain and riding style.
Routine Maintenance
Maintaining the 34 Float Factory GRIP2 prolongs its performance and reliability. Fox recommends lower leg service every 50 hours and full damper service every 125 hours.
Lower leg service includes draining old oil, removing the lowers, cleaning internal surfaces, and replacing the dust wipers and foam rings. Reassemble with fresh oil and recheck all torque values.
Inspect stanchions and seals after every few rides for signs of wear or oil leakage. Clean the stanchions with a soft rag and isopropyl alcohol to remove dust buildup.
Troubleshooting Common Set-Up Issues
Many users experience harshness or inconsistent rebound when first using the GRIP2 damper. This often results from incorrect rebound settings or too little sag. Verify the sag with proper air pressure and recheck your rebound clicks.
Another issue is creaking at the crown, which may indicate a manufacturing defect or improperly torqued headset preload. Retorque the headset and inspect the crown-to-stanchion interface.
If the fork dives too much under braking, increase the low-speed compression a few clicks. For excessive top-out clunking, adjust rebound damping higher.
Customization and Performance Optimization
The 34 Float Factory GRIP2 offers tuning options through volume spacers. Adding a spacer increases progression, preventing bottom-out on big hits. Removing one makes the fork more linear.
For riders on undulating or technical trails, running slightly less high-speed compression improves small bump compliance. However, aggressive descenders may prefer more compression damping and added volume spacers.
Upgrading to SKF low-friction seals can enhance sensitivity, especially in cold climates. Additionally, regularly applying dynamic suspension lube can reduce stiction.
Compatibility with Other Drivetrain and Frame Components
The 34 Float Factory GRIP2 is compatible with 15x110mm Boost hub spacing and flat mount or post-mount brake calipers, depending on the model. It supports up to 203mm rotors with the correct adapters.
Steerer is tapered (1.5 to 1 1/8 inch), so confirm headset compatibility with your frame. Its chassis allows for tire clearance up to 2.6 inches, ensuring compatibility with most trail tires.
Ensure that the crown race matches your headset, and check for any frame interference at full compression, especially on bikes with aggressive head tube angles.
Comparison: 34 Float Factory GRIP2 vs. Other Top Models
When compared to the RockShox Pike Ultimate, the 34 Float Factory GRIP2 offers a more precise damping range due to its GRIP2 damper. The Pike’s Charger 3 damper is more intuitive but lacks the depth of tuning for high-speed compression.
Against the Öhlins RXF34 m.2, the GRIP2 offers a lighter weight and better small bump compliance. However, the Öhlins fork may appeal to riders looking for plush, coil-like support through rough descents.
The DVO Sapphire D1 comes with on-the-fly adjustments but doesn’t match the 34 Factory’s chassis stiffness or Kashima-coated durability.
In weight-sensitive builds, the 34 Factory often edges out these competitors while still maintaining premium stiffness and performance balance.
Frequently Asked Questions
1. Can I use the 34 Float Factory GRIP2 for enduro riding?
It’s best suited for trail and aggressive XC, but it can handle light enduro depending on your weight and riding style.
2. How often should I service the GRIP2 damper?
A full damper service is recommended every 125 hours of riding time or annually.
3. What’s the max rotor size supported?
Up to 203mm rotors with the correct adapter.
4. Is the 34 Float Factory GRIP2 compatible with 27.5” wheels?
This specific model is designed for 29” wheels. A 27.5” version is available but must be purchased separately.
5. What is the main advantage of the Kashima coating?
Reduced friction, improved responsiveness, and longer-lasting performance.
6. Can I install this fork on a non-Boost frame?
No, the 34 Float Factory GRIP2 is designed for Boost spacing (15x110mm) only.
