The Fox 32 Float Factory Step-Cast suspension fork is engineered for cross-country riders who demand lightweight performance, superior damping control, and exceptional trail feedback. Designed with the FIT4 damper and EVOL air spring, it delivers consistent ride quality across varied terrain. This guide provides a comprehensive look into the installation, adjustment, and optimization of this fork, helping you achieve the best comfort and control from your setup.
Tools Required
- 5mm and 6mm Allen wrenches [paid link]
- Torque wrench [paid link] (2-10 Nm range)
- Star nut setting tool
- Crown race setting tool
- Suspension pump
- Isopropyl alcohol and clean rags
- Caliper and fork cutting guide (if steerer tube needs trimming)
- Suspension-specific grease
- Fox suspension oil (as specified in the service manual)
Installation of the 32 Float Factory Step-Cast Fork
The 32 Float Factory Step-Cast fork installation requires precision to ensure optimal function and safety. Begin by verifying the fork’s steerer tube length. If trimming is needed, measure the head tube stack height, add headset and stem thickness, and allow for 3mm spacer clearance before cutting. Always use a fork cutting guide for clean, straight cuts.
Install the star nut using the setting tool. Grease the crown race seat and install the crown race with a press tool. Fit the fork into the frame, align spacers and stem, then preload the headset. Torque the stem bolts to specification—typically 5 Nm—to secure the setup. Check for smooth steering and no play in the headset.
Suspension Setup and Adjustment
Fox’s FIT4 damper allows for three primary compression settings: Open, Medium, and Firm. These modes cater to different trail conditions and rider preferences. For riders focused on comfort, the Open mode offers the most plush travel, ideal for technical XC tracks or rough terrain.
Use a suspension pump to set the air pressure according to the rider’s weight and desired feel. Fox’s recommended starting point is typically 15-20% sag. Sit on the bike in full gear to measure sag, adjusting as needed for terrain-specific compliance.
In Open mode, use the low-speed compression adjuster to fine-tune the fork’s response to rider input. Backing out the adjuster increases comfort and small bump sensitivity. Rebound damping should be dialed in based on ride feel, aiming for a controlled return without harsh top-out.
Maintenance and Service Intervals
Regular maintenance preserves the performance and lifespan of the 32 Float Factory Step-Cast. Every 30 hours of riding, clean the stanchions and wipers with isopropyl alcohol and check for oil residue or grit accumulation. Lubricate the wiper seals with suspension-specific grease.
At 50 hours, perform a lower leg service. This includes draining old oil, cleaning the internals, and replenishing with new Fox suspension oil. Inspect foam rings, replace worn seals, and ensure bushings are tight. Use a torque wrench [paid link] for reassembly, tightening bolts to Fox’s recommended specifications.
At 125-hour intervals, a full damper and air spring service is required. This should be completed by an experienced mechanic or authorized Fox service center unless the user has prior suspension experience.
Troubleshooting Common Set-Up Issues
Several setup issues can affect the fork’s comfort and performance:
- Harsh ride: Often caused by overinflated air pressure or excessive low-speed compression. Reduce air pressure or open the compression adjuster.
- Fork dives under braking: May result from too little air pressure or too much rebound damping. Increase air pressure slightly and reduce rebound damping.
- Top-out noise: Usually indicates insufficient rebound damping or internal air spring imbalance. Adjust rebound knob or bleed the negative air chamber using the air cap release valve.
Always check air pressure and damper settings before each ride, especially after major temperature changes or transportation.
Customization and Optimization
To further tailor ride comfort, riders can install volume spacers inside the air spring. Reducing volume (adding spacers) increases progression and bottom-out resistance, while removing them makes the fork more linear and supple throughout the travel.
Tuning the FIT4 damper by adjusting the compression shim stack is another option, though this is best performed by advanced users or service technicians. Handlebar-mounted lockout remotes are available for on-the-fly mode switching, ideal for endurance racers.
Pairing the fork with a compliant handlebar, lower tire pressures, and tubeless tires can also enhance overall front-end comfort.
Comparison with Similar Models
Compared to the Fox 34 SC or RockShox SID SL, the 32 Float Factory Step-Cast prioritizes minimal weight and quick handling. It is best suited for riders who prioritize efficiency and low weight over stiffness. The 34 SC, while heavier, offers greater lateral stiffness, making it a better option for aggressive riders or heavier cyclists.
The RockShox SID SL offers similar travel and damping features but uses a different air spring (DebonAir) and Charger Race Day damper. Riders may prefer the SID SL for its slightly more linear feel and lighter remote lockout system.
Compatibility with Drivetrain and Frame Standards
The 32 Float Factory Step-Cast is compatible with modern XC frames featuring tapered head tubes (1.5″ to 1 1/8″). It uses a 15x110mm Boost axle standard, which aligns with current wheel specs for improved stiffness and clearance.
It fits frames with flat-mount or post-mount brake systems using appropriate adapters. The fork also accommodates rotor sizes from 160mm to 180mm, ensuring compatibility with a wide range of XC brake setups.
This fork integrates smoothly with 1x and 2x drivetrains and does not interfere with narrow-wide chainring setups or front derailleurs. Ensure cable routing avoids kinks or friction, especially with handlebar lockout installations.
Frequently Asked Questions
What is the maximum rotor size for the 32 Float Factory Step-Cast?
The fork supports rotor sizes up to 180mm with proper adapter use.
How often should I service the lower legs of the fork?
Every 50 hours of riding or sooner if you notice reduced performance or oil seepage.
Can I install a remote lockout on this fork?
Yes, the FIT4 damper is compatible with Fox’s remote lockout kits for handlebar control.
Is the 32 Step-Cast suitable for trail riding?
While optimized for XC racing, it can handle light trail use but may feel flexy on aggressive descents.
Can I use this fork with a 29×2.4” tire?
Yes, it fits most 29×2.4” tires, but always check actual tire width and clearance.
What is the difference between Factory and Performance Series forks?
The Factory series includes Kashima-coated stanchions and more tuning options, offering better small bump compliance and durability.
