The Fox 34 Float Factory GRIP2 suspension fork represents a high-performance solution for trail riders seeking advanced damping control, superior responsiveness, and fine-tuned adjustability. Designed specifically for aggressive trail applications, this fork integrates the latest in suspension technology while maintaining the lightweight performance that defines the Factory series.

Tools Required

  • Torque wrench [paid link] (Nm scale)
  • 6mm, 4mm, and 2mm Allen keys [paid link]
  • Suspension pump
  • Shock oil (Fox 20wt Gold or recommended alternative)
  • Clean rags and isopropyl alcohol
  • Crown race setting tool
  • Star nut setting tool

Installation Procedure

Installing the 34 Float Factory GRIP2 requires care and precision. Begin by ensuring compatibility with your frame’s head tube and brake caliper mounts. The fork fits 29” wheels and is available in several travel options, typically ranging from 120mm to 140mm.

Before cutting the steerer tube, perform a dry fit to check headset stack height. Once the desired length is confirmed, cut the steerer tube cleanly using a pipe cutter or saw guide. Install the star nut using the correct tool, and fit the crown race. Mount the fork to the frame, grease headset bearings, and torque the stem bolts to manufacturer specifications.

Attach the front brake caliper and ensure alignment. Mount the wheel and confirm rotor clearance. Inflate the fork to your sag preference, typically around 20-30% of travel.

Adjustment Guidelines

The GRIP2 damper provides independent high-speed and low-speed compression and rebound adjustments. This four-way adjustability allows riders to precisely tailor the ride feel.

  • Low-speed compression (LSC) controls chassis stability, such as brake dive and body movement during slow-speed terrain.
  • High-speed compression (HSC) governs responses to impacts like roots and drops.
  • Low-speed rebound (LSR) manages fork extension during gradual weight shifts.
  • High-speed rebound (HSR) determines how quickly the fork recovers after quick compressions.

Adjustments are made via dials located on the top of the right fork leg (compression) and bottom of the same leg (rebound). Each click significantly impacts performance, so adjustments should be incremental and based on test rides.

Routine Maintenance

Regular maintenance is critical to keep the 34 Float Factory GRIP2 performing at its peak. Fox recommends servicing the lower legs every 30 hours of ride time. This process involves removing the lowers, cleaning the internals, and replacing the bath oil.

Annually, or every 100 hours, perform a full damper and air spring service. This includes replacing seals, inspecting bushings, and bleeding the GRIP2 damper if needed. Always use genuine Fox parts and follow torque specs during reassembly.

Clean the stanchions after every ride to prevent debris from damaging the seals. Inspect the fork for oil seepage, especially around the dust wipers, which may indicate a need for service.

Troubleshooting Common Issues

Riders occasionally experience setup challenges with the GRIP2. Here are some frequent issues and their solutions:

  • Excessive brake dive often indicates insufficient LSC or air pressure. Increase LSC or add volume spacers to adjust spring ramp-up.
  • Harshness on small bumps can stem from excessive HSC or rebound damping. Reduce HSC or adjust HSR for more sensitivity.
  • Fork not returning fully may result from too much rebound damping or a sticking air piston. Check air pressure and reduce LSR if necessary.
  • Noisy damper performance can signal air in the GRIP2 system. A full bleed is required to restore quiet, smooth operation.

Customization and Performance Optimization

The 34 Float Factory GRIP2 offers riders numerous avenues for customization. Volume spacers inside the air spring can alter the spring curve, enabling progressive or linear feel adjustments. Fewer spacers offer a more linear feel, while additional spacers increase progression for aggressive riding.

Tuning the damper to match terrain and rider style enhances performance. For example, reducing HSC for smoother trails or increasing LSR for flow trails helps match the fork’s response to specific riding demands.

Additionally, installing aftermarket seals or low-friction wipers can enhance small bump sensitivity, though these may slightly reduce longevity compared to stock components.

Model Comparison and Selection

When compared to other Fox models, the 34 Float Factory GRIP2 stands out for its superior damping control. Unlike the Performance or Rhythm versions that use the FIT4 or GRIP dampers, the GRIP2 offers independent four-way adjustability, making it ideal for tuning-centric riders.

Compared to the Fox 36 series, the 34 is lighter and more suitable for trail use rather than enduro or aggressive downhill. However, if your riding style includes more technical terrain or heavier impacts, the 36 might be a better fit despite the added weight.

RockShox competitors like the Pike Ultimate offer similar weight and tuning options but may not match the mid-stroke support and adjustability of the GRIP2, especially in high-speed damping control.

Component Compatibility

The 34 Float Factory GRIP2 is compatible with 29” wheels and Boost spacing (110x15mm). It requires a tapered head tube and flat mount disc brakes. For drivetrains, it integrates seamlessly with 1x and 2x setups, but its performance is best matched with modern 1x drivetrains, which reduce front-end weight and complexity.

Ensure that the front brake rotor size matches the fork’s post-mount standard—160mm native, with adapters available for up to 203mm. The axle system uses a Kabolt or QR15, depending on configuration, and it’s critical to match axle dimensions precisely for safety and function.

Frequently Asked Questions

Q1: What air pressure should I use in the 34 Float Factory GRIP2 fork?
A1: Refer to the Fox air pressure chart, which recommends pressures based on rider weight. Typically, 70-80 psi suits a 70 kg rider for 130mm travel, but sag should be used as the primary setup guide.

Q2: Can I install the GRIP2 damper in a Fox 34 Performance fork?
A2: No, the chassis of the Factory model is specifically designed for the GRIP2 damper. Retrofitting is not supported and can compromise fork performance and safety.

Q3: How often should I change the oil in the GRIP2 damper?
A3: The lower leg oil should be refreshed every 30 hours of riding. The GRIP2 damper itself should be serviced at least every 100 hours or annually, whichever comes first.

Q4: Does the GRIP2 damper allow for lockout functionality?
A4: No, the GRIP2 prioritizes adjustability and damping performance over lockout capability. Riders looking for lockout should consider the FIT4 damper version.

Q5: What are the signs that the fork needs a full service?
A5: Indicators include decreased sensitivity, oil leakage, unusual noises, or inconsistent rebound. Performance degradation over time is a normal sign that a service is due.

Q6: Can I upgrade the air spring to increase travel?
A6: Yes, the Fox 34 chassis allows travel changes in 10mm increments by swapping the air spring assembly. Ensure that changes do not exceed the chassis limits.
