Tools Required
- 5mm and 6mm Allen keys [paid link]
- Torque wrench [paid link] (Nm scale)
- Shock pump with PSI gauge
- Star nut setter or compression plug tool
- Crown race setting tool
- Caliper or rotor alignment gauge
- Fork-specific suspension grease
- Fox suspension fluid (recommended grade)
- Isopropyl alcohol (for cleaning)
Installation of the 32 Float Factory Step-Cast
Proper installation is vital for the safety and function of the Fox 32 Float Factory Step-Cast. The fork features a tapered steerer and a 100mm travel range optimized for XC racing setups.
Start by measuring and cutting the steerer tube to match your frame and cockpit. A star nut or compression plug must be inserted correctly to maintain headset tension. Next, install the crown race that matches your headset bearing system. When sliding the fork into the head tube, ensure that headset bearings and spacers are aligned accurately. Finally, torque the stem bolts to the manufacturer’s recommended settings to avoid damage to the carbon steerer.
Install the front brake caliper with care. The flat-mount or post-mount system must be aligned precisely with the rotor. Fox’s proprietary Kabolt or quick-release axle must be torqued properly to prevent flex or misalignment under braking.
Suspension Setup and Adjustment
The Factory series includes the FIT4 damper and EVOL air spring, offering premium adjustment capabilities. Begin with setting the correct air pressure based on rider weight. Fox provides a chart as a baseline, but fine-tuning may be necessary for optimal performance.
Rebound is controlled via a red dial at the fork’s bottom leg, while the blue dial at the crown manages low-speed compression. The FIT4 system also includes a three-position lever—Open, Medium, and Firm—to adapt to trail conditions. Use the Open Mode Adjust feature to dial in low-speed compression within the Open setting for precise terrain response.
Always use a shock pump to adjust PSI, and never exceed Fox’s stated pressure limits. Adjustments should be tested in short rides to ensure the fork behaves as expected under trail loads.
Routine Maintenance and Service Intervals
Fox recommends lower leg service every 30 hours of riding and a full damper service every 125 hours. Regular maintenance ensures consistent performance and prevents internal damage.
Lower leg service involves removing the lowers, cleaning seals and bushings, and reapplying suspension-specific grease and oil. Use isopropyl alcohol to clean the internals. Check for seal wear or contamination that may affect stanchion lubrication.
For damper service, it’s essential to follow Fox’s torque and fluid specifications. If unfamiliar, consider sending the fork to an authorized Fox service center. Keeping service intervals regular preserves performance and increases longevity.
Troubleshooting Common Setup Issues
Some riders encounter excessive fork dive or insufficient small-bump compliance. These symptoms usually stem from incorrect air pressure or damping settings. Increase air pressure incrementally and test compression settings to find a balance between support and comfort.
Stiction or rough initial movement may result from dry seals or low oil levels. If the fork feels sticky, perform a lower leg service and inspect the foam rings for proper lubrication.
If the fork tops out with a clunk, rebound may be set too fast. Dial in slower rebound increments until the harsh return is mitigated.
Customization and Performance Optimization
Riders can install volume spacers in the air spring to fine-tune progression. Adding spacers makes the fork ramp up more aggressively, ideal for aggressive XC riders. Removing spacers increases linearity for a plush ride on smoother trails.
The FIT4 damper can be factory-tuned or modified with valving kits, though this should be done only by advanced users or service professionals.
Lightweight axle upgrades and carbon crown/steerer units are available for further weight savings, though these typically come stock on higher-end trims.
Compatibility with Drivetrain and Frame Standards
The 32 Float Factory Step-Cast is compatible with most modern XC frames using tapered steerer tubes and Boost (110mm) axle spacing. Brake compatibility includes 160mm direct-mount rotors, with adapters available for larger sizes.
Ensure that the fork’s crown clearance fits your chosen frame’s head tube. The short offset versions (44mm or 51mm) allow for tailored handling depending on frame geometry.
This fork integrates well with SRAM, Shimano, and TRP brake systems, provided proper adapters and alignment are used. Ensure brake hose routing allows full range of motion without binding.
Comparison with Similar Fork Models
Compared to the RockShox SID SL, the Fox 32 Float Factory Step-Cast offers more external adjustability and a slightly firmer platform in Firm mode. The EVOL air spring also contributes to better small-bump sensitivity than some competitors.
Relative to the Fox 34 SC, the 32 is lighter and more race-focused. The 34 offers increased stiffness and better support under aggressive descending but at a small weight penalty.
Riders focused on climbing efficiency and gram shaving will favor the 32 Step-Cast, while those tackling technical XC courses may consider a step up to 34mm stanchions for extra support.
Frequently Asked Questions
1. Can I install the 32 Step-Cast on a trail bike?
No, the fork is optimized for XC geometry and riding. It lacks the stiffness and travel needed for trail or enduro bikes.
2. How do I know what air pressure to use?
Refer to Fox’s recommended pressure chart based on rider weight. Fine-tune by test riding and adjusting in 2-5 PSI increments.
3. Can I use this fork with a 29” front wheel?
Yes, it supports 29” wheels with tire clearance up to 2.3”. Always verify frame and tire clearance together.
4. How often should I service the fork?
Every 30 hours for lower leg service, and 125 hours for full damper service. Dirty conditions may require shorter intervals.
5. Is the FIT4 damper user-serviceable?
Fox recommends this be handled by certified service centers, though experienced users with the right tools can follow service manuals.
6. What is the weight of the 32 Float Factory Step-Cast?
Approximately 1,350 grams, making it one of the lightest 100mm travel forks available in the market today.
