The Fox 32 Float Factory Step-Cast is a lightweight, performance-focused cross-country suspension fork designed for aggressive racers and serious riders. With its Step-Cast chassis, FIT4 or GRIP dampers, and Kashima-coated stanchions, this fork blends weight savings with responsive damping. However, to get the most out of it, proper tuning, adjustment, and maintenance are essential.
This guide breaks down every aspect of installing, adjusting, and optimizing the 32 Float Factory Step-Cast suspension fork. Whether you’re new to bike suspension or fine-tuning for peak performance, this guide will help you understand this component in full.
Tools Required
- Torque wrench [paid link] with appropriate bits
- Shock pump (high-pressure)
- Suspension grease
- Allen key set (4mm, 5mm, 6mm)
- Clean lint-free cloth
- Suspension fluid (as per Fox specs)
- Isopropyl alcohol (for cleaning seals)
- Sag meter or tape measure
Installing the 32 Float Factory Step-Cast
Proper installation is critical for safety and performance. Begin by confirming that the steerer tube length is compatible with your frame and headset configuration.
- Cut the Steerer Tube: Use a pipe cutter or hacksaw with a guide. Always measure twice and cut once.
- Install the Crown Race: Press-fit the appropriate crown race for your headset.
- Insert the Star Nut or Threaded Insert: Depending on your setup, drive in a star nut or install a threaded insert if using a compression plug.
- Mount the Fork to the Frame: Slide the fork into the head tube, stack the spacers, stem, and headset cap.
- Torque Everything Correctly: Use a torque wrench [paid link] to tighten the stem bolts to manufacturer specifications—typically 5–6 Nm.
Understanding Air Spring Setup
The 32 Float Factory Step-Cast uses a FLOAT air spring that requires accurate setup to perform optimally.
Setting the Air Pressure:
Refer to Fox’s rider weight chart to get a baseline air pressure. This figure is a starting point and should be adjusted after a sag test.
Checking and Adjusting Sag:
Sag represents how much the fork compresses under your body weight. For cross-country riding, aim for 15–20% sag.
- Measure the exposed stanchion length.
- Sit on the bike in a neutral riding position.
- Measure sag and adjust air pressure accordingly.
Rebound Damping:
The red dial at the fork’s base controls rebound speed. Begin with the middle setting and fine-tune depending on your riding terrain.
Compression Damping Adjustment
Depending on the damper model—FIT4 or GRIP—you’ll have different options:
FIT4 Damper:
- Three-position lever (Open, Medium, Firm)
- 22-click Open Mode adjuster for fine-tuning
GRIP Damper:
- Infinite adjustment with compression dial
- Simpler, lower-maintenance setup
Use “Open” for descents, “Medium” for undulating trails, and “Firm” for climbs or sprints. Adjust the Open mode clicks for personalized feel during aggressive trail riding.
Routine Maintenance Schedule
Maintaining your suspension fork ensures longevity and peak performance.
Every Ride:
- Wipe stanchions clean after each ride.
- Check for oil seepage around dust wipers.
Every 30 Hours:
- Clean and inspect foam rings and dust wipers.
- Add suspension-specific lubricant to keep seals supple.
Every 100 Hours or Annually:
- Perform a lower leg service: drain and replace the bath oil.
- Inspect bushings and internal wear.
- Replace seals if dry or cracked.
Always use Fox-specified fluids and follow the torque specs for reassembly.
Troubleshooting Common Issues
Fork Not Rebounding Quickly Enough:
- Check if rebound is set too slow.
- Ensure correct air pressure to avoid under-sprung conditions.
Excessive Sag or Fork Diving:
- Air pressure might be too low.
- Add volume spacers to increase progression if bottoming out frequently.
Clicking or Knocking Sounds:
- Inspect headset for play.
- Check damper or air shaft for internal wear if sound persists.
Oil Leakage from Seals:
- Replace wiper seals and foam rings.
- Ensure seals are properly lubricated during service.
Customization and Performance Optimization
Volume Spacers:
Add or remove volume spacers inside the air chamber to change the fork’s spring curve. More spacers = more progression (harder to bottom out). Fewer spacers = more linear feel.
FIT4 Open Mode Adjuster:
Dial in the low-speed compression in Open mode to control mid-stroke support during aggressive cornering or braking.
Axle to Crown Height Adjustments:
Ensure proper axle-to-crown height match with your frame’s geometry. A mismatch can alter your bike’s steering and handling characteristics.
Compatibility with Other Components
Steerer Tube: 1.5” to 1-1/8” tapered, compatible with most modern XC frames.
Axle System: 15x110mm Boost spacing, be sure your hub matches the fork’s spacing.
Rotor Size: Designed for 160mm post-mount rotors; adapters available for 180mm setups.
Remote Lockout: Available on select models, ensure your handlebar has space and cable routing.
Comparison with Similar Models
Fox 34 Step-Cast:
- More trail-oriented with increased stiffness and travel options up to 120mm.
- Heavier but offers better descending stability.
RockShox SID SL:
- Comparable weight, slightly simpler damper.
- SID Ultimate offers TwistLoc remote lockout, similar to Fox’s remote options.
DT Swiss F232 ONE:
- Lighter, minimalist design focused on elite XC racers.
- Lacks the tuning range of the FIT4 but offers ultra-low weight.
The 32 Float Factory Step-Cast strikes a balance between adjustability, stiffness, and weight, making it a standout for competitive cross-country applications.
Frequently Asked Questions
What is the recommended air pressure for the 32 Float Factory Step-Cast?
Use Fox’s official air pressure chart based on rider weight. Adjust based on sag for optimal performance.
How often should I service my 32 Float Factory Step-Cast fork?
Clean the stanchions after every ride, perform a lower leg service every 30–50 hours, and a full damper service every 100 hours.
Can I install a remote lockout on this fork?
Yes, but only if the fork model includes the remote-compatible damper. Verify with your specific build.
Why is my fork making a clicking noise?
Check for headset looseness or worn bushings. Also inspect damper and air spring components during service.
What’s the difference between FIT4 and GRIP dampers?
FIT4 offers more tuning options and is better for riders seeking fine control. GRIP is simpler and more robust for lower maintenance.
Can I use a 180mm rotor with the Step-Cast 32?
Yes, with a proper adapter. The fork is post-mount 160mm by default.
