The Fox 32 Float Factory Step-Cast fork represents one of the most performance-driven cross-country suspension forks in the market. With an emphasis on lightweight design, precision damping, and stiffness-to-weight optimization, this fork delivers premium performance for riders seeking to maximize speed and efficiency on the trail. This guide details the installation, setup, and long-term care of the 32 Float Factory Step-Cast, alongside performance optimization and troubleshooting tips.

Tools Required

• Torque wrench [paid link] with hex bit set
• Crown race setting tool
• Star nut setting tool (for non-tapered steerer tubes)
• Suspension pump
• Shock oil and seals (for service)
• Caliper alignment tools
• Clean lint-free rags
• Isopropyl alcohol

Installation Process

Proper installation of the 32 Float Factory Step-Cast is critical to performance and safety. Begin by verifying the steerer tube length. Cut it to match your frame and cockpit configuration, allowing space for spacers and the headset preload cap. Install the star nut using a setting tool or a thread-in star nut setter to maintain alignment.

Once the crown race is pressed onto the steerer and the fork is inserted into the head tube, align the headset spacers and stem. Tighten the top cap to preload the headset bearings before securing the stem bolts to the recommended torque. Ensure the brake caliper is aligned with the 32 Step-Cast’s proprietary flat-mount interface and that the rotor clears the lower leg arch cleanly.

Suspension Setup and Adjustment

The 32 Float Factory Step-Cast features the FIT4 damper, which provides three on-the-fly compression damping modes: Open, Medium, and Firm. These modes allow the rider to fine-tune the fork’s response depending on terrain and riding style.

Set the sag between 15% and 20% of the fork’s travel using a suspension pump to achieve your desired air pressure. Adjust rebound using the red dial at the bottom of the right leg. Start at the middle of the adjustment range and fine-tune based on trail feedback, keeping response controlled without excessive oscillation.

The blue top cap houses the low-speed compression adjuster. In Open mode, you can further refine low-speed compression to accommodate terrain variability. For racing or smoother terrain, Medium or Firm modes offer improved pedaling support.

Routine Maintenance Guidelines

To extend the performance life of your 32 Float Factory Step-Cast, regular maintenance intervals must be followed. After every 30 hours of ride time, clean the stanchions and dust wipers. Inspect for oil residue, which may indicate seal wear or contamination. Use isopropyl alcohol and a soft cloth to clean the exterior surfaces.

After every 125 hours or yearly, whichever comes first, perform a lower leg service. Replace bath oil, foam rings, and dust seals. This process ensures lubrication integrity and prevents contamination. Fox specifies 20wt Gold Bath Oil for optimal performance in the lower legs.

The air spring should be inspected annually. Replacing seals and refreshing grease helps retain responsiveness and prevents air leaks that could affect sag or travel consistency.

Troubleshooting Common Issues

If the fork feels harsh or unresponsive, verify that the air pressure matches rider weight and that sag is within acceptable limits. An over-pressurized fork can limit travel and result in a harsh ride.

Should the fork feel bouncy or dive under braking, consider increasing compression damping or adjusting rebound to slow down return. Inconsistent damping behavior may indicate contamination in the damper or a need for a full rebuild.

Noise from the crown or creaking under load may point to insufficient headset preload or an inadequately torqued stem. Inspect and re-torque all fasteners as specified by Fox’s technical manual.

Customization and Performance Optimization

The 32 Float Factory Step-Cast is highly tunable for weight-conscious riders or racers. Lightweight titanium bolts, remote lockouts, or reduced spacer configurations can shed grams without sacrificing structural integrity.

To enhance small bump sensitivity, consider upgrading to low-friction SKF wiper seals. Riders seeking more control over compression can utilize Fox’s Remote FIT4 cartridge, allowing bar-mounted control for rapid terrain adaptation.

Volume spacers allow tuning of the air spring’s progressiveness. Adding spacers increases end-stroke ramp-up, suitable for aggressive riders or courses with high-speed descents. Removing spacers softens the mid-to-end stroke, enhancing plushness.

Comparing the 32 Step-Cast to Similar Models

Compared to the Fox 34 Step-Cast, the 32 offers a narrower chassis and lighter weight, best suited for pure cross-country use. While the 34 SC handles more aggressive trail conditions, the 32 is unmatched for speed-focused XC racing.

Against competitors like the RockShox SID SL, the 32 Step-Cast delivers superior damper refinement via FIT4 and more tuning options. The Step-Cast lowers also offer better mud clearance and a wider stance, improving torsional stiffness.

Compatibility with Drivetrain and Braking Systems

The 32 Float Factory Step-Cast uses a Boost 110mm axle spacing and fits flat-mount disc brakes up to 180mm with adapters. The design integrates seamlessly with 29” wheelsets and is optimized for 2.2” to 2.4” XC tires.

It supports tapered steerer tube headsets and pairs well with lightweight carbon or aluminum XC frames. The fork’s chassis stiffness accommodates 1x drivetrains with no interference from chainrings or cranks, maintaining frame compatibility across most race-oriented designs.

FAQs

1. Can I use the 32 Step-Cast on a trail bike instead of an XC bike?
The 32 Step-Cast is designed primarily for cross-country use. While it may fit some light trail bikes, its stiffness and travel (100-120mm) may not be sufficient for aggressive trail conditions.

2. How often should I service the 32 Step-Cast fork?
Perform basic lower leg maintenance every 30 hours of riding and a full service (including air spring and damper) every 125 hours or annually.

3. What is the difference between FIT4 and GRIP dampers?
FIT4 offers greater tuning flexibility with multiple compression modes and is better suited for competitive riders, whereas GRIP dampers use a simpler open-bath system ideal for general trail use.

4. Are volume spacers included with the fork?
Yes, Fox includes volume spacers that allow riders to adjust the fork’s air spring progression to suit personal preferences.

5. What type of brake mounts does the fork use?
The 32 Step-Cast uses a flat-mount disc brake interface, compatible with rotors up to 180mm with appropriate adapters.

6. Can I install a remote lockout on this fork?
Yes, the 32 Step-Cast supports an optional remote lockout upgrade for the FIT4 damper, providing handlebar control of compression modes.

7. What is the maximum tire size compatible with this fork?
The fork accommodates 29” tires up to 2.4” in width, ensuring clearance for most cross-country race setups.
