Tools Required
Before starting the installation or maintenance of the Float X2 Factory, ensure you have the following tools:
- 5mm and 6mm Allen wrenches [paid link]
- Torque wrench [paid link]
- Suspension fluid (Fox recommended)
- 8mm wrench (for eyelet mounting)
- Shock pump (compatible with Fox shocks)
- Rags for cleaning
- Isopropyl alcohol
- Soft brush
- Grease (Fox recommended)
- T20 or T25 Torx wrench [paid link] (for some models)
- Small bucket (for draining shock fluid if necessary)
Installation of the Float X2 Factory Rear Shock
Installing the Fox Float X2 Factory rear shock requires precision to ensure proper function and safety. Follow these steps to properly install the shock onto your mountain bike frame.
Step 1: Prepare Your Work Area
Ensure you have a clean and organized workspace to work on your bike. A clean environment will prevent contamination during installation.
Step 2: Remove the Old Shock (if applicable)
If you’re replacing an existing shock, use your 5mm or 6mm Allen wrenches [paid link] to remove the bolts securing the shock. Be sure to keep the bolts and any washers in a safe location as you’ll need them for the new shock.
Step 3: Install the Float X2 Factory
- Align the Float X2 Factory’s mounting eyelets with the frame’s shock mounts.
- Carefully insert the shock into the mounting points, ensuring the shock is aligned correctly.
- Install the mounting bolts and torque them to the specifications recommended by Fox, typically between 180–200 in-lbs for most models. Use a torque wrench [paid link] to avoid over-tightening or under-tightening.
- Recheck the alignment and ensure the shock is seated correctly.
Step 4: Set the Air Pressure
Use a shock pump to set the correct air pressure based on your weight and riding style. Refer to the Fox guidelines for recommended air pressures based on rider weight. The correct air pressure is crucial for optimal performance, so ensure it is set accurately.
Step 5: Test the Installation
Once the shock is mounted and the air pressure is set, manually compress the shock to ensure it moves freely. Check for any binding or obstruction in the shock’s travel.
Adjustment of the Float X2 Factory
The Float X2 Factory rear shock features multiple adjusters, allowing riders to fine-tune their ride to their exact preferences. Proper adjustment is key to extracting maximum performance and comfort.
Rebound Adjustment
Rebound controls the speed at which the shock returns after compression. A slower rebound offers better control on rough trails, while a faster rebound is ideal for smoother rides. To adjust the rebound:
- Locate the rebound adjuster on the shock.
- Turn the knob clockwise for slower rebound (ideal for rough terrain).
- Turn the knob counterclockwise for faster rebound (ideal for smoother trails).
Compression Adjustment
The Float X2 Factory features both high-speed and low-speed compression adjusters. These control the shock’s damping during compression, allowing for better control on different trail conditions.
- Low-speed Compression: Adjusts the compression for slower impacts and is ideal for fine-tuning the shock’s behavior during pedaling and body movements.
- High-speed Compression: Adjusts the shock’s response to faster, more aggressive impacts, such as drops or rock gardens.
To adjust the compression:
- Locate the compression knobs on the shock body.
- Turn the low-speed compression knob counterclockwise to decrease compression (softer response).
- Turn the high-speed compression knob counterclockwise to decrease compression for faster impacts.
Bottom-Out Control
The Float X2 Factory shock also features a bottom-out control system to prevent harsh impacts when the shock reaches the end of its travel. Adjusting this can significantly improve rider comfort and reduce the risk of damaging the shock.
Air Volume Tuning
The Float X2 allows for adjustment of the air spring’s volume via spacers. Adding or removing spacers will change the ramp-up of the shock’s compression, providing either more or less progression at the end of the shock’s stroke. For a more progressive feel, add spacers, while fewer spacers will offer a more linear feel.
Maintenance of the Float X2 Factory
Proper maintenance ensures that your Float X2 Factory shock remains in peak condition throughout its lifespan. Regular maintenance can also help avoid costly repairs and performance issues.
Regular Cleaning
After each ride, wipe down the shock with a clean rag to remove dirt and debris. Use a soft brush to clean out the crevices around the shock’s seals, and apply isopropyl alcohol to ensure the seals remain free from contaminants. Keeping the shock clean will prolong its life and improve performance.
Oil and Seal Maintenance
Fox recommends servicing the Float X2 Factory shock every 30-50 hours of riding. During a service, you will need to replace the oil and check the seals for wear.
- Remove the shock from the bike.
- Disassemble the shock carefully, noting the orientation of all components.
- Drain the old oil and replace it with fresh suspension fluid (Fox recommends their own suspension oil).
- Check the seals for any signs of wear, cracks, or damage. Replace if necessary.
- Reassemble the shock, ensuring everything is lubricated properly.
Annual Overhaul
It is recommended to perform a full overhaul of the shock once per year, or every 100-150 hours of riding. This service should include a thorough inspection, full oil change, and seal replacement. Professional servicing is advised for this step, as it involves more complex disassembly.
Troubleshooting Common Issues with the Float X2 Factory
Despite its high-performance design, there are a few issues you may encounter with the Float X2 Factory rear shock. Here are some common problems and how to troubleshoot them:
Shock Not Holding Air Pressure
If your shock is losing air pressure, inspect the shock’s air valve for any damage or leaks. Check the seals and the Schrader valve for proper sealing. If the problem persists, it might be time to replace the seals.
Uneven Compression
If you experience uneven compression or the shock feels too soft or too stiff, check the air pressure settings. Incorrect air pressure can cause the shock to feel out of balance. Additionally, inspect the compression adjusters to ensure they are functioning correctly.
Excessive Rebound
Excessive rebound can occur if the rebound adjuster is set too fast. Slow down the rebound by turning the knob clockwise. If the problem persists, the shock may need to be serviced.
Customization and Optimization for Better Performance
The Float X2 Factory shock is highly customizable, allowing you to optimize it for your specific riding style and terrain preferences. Here are some tips for getting the most out of your shock:
- Adjust Air Pressure for Weight: Always adjust the air pressure based on your body weight and riding style. A higher pressure will provide more support for aggressive riders, while a lower pressure is better suited for smoother rides.
- Tune Compression for Terrain: Adjust the low-speed compression based on the trail type. For technical, slow-speed riding, set the compression to a softer setting. For fast descents, increase compression to avoid bottoming out.
- Experiment with Air Volume: For more technical riding or aggressive trails, consider adding spacers to increase the air spring’s progression, preventing harsh bottom-outs.
Comparison with Other Models
When comparing the Float X2 Factory to other shocks in its class, such as the RockShox Super Deluxe or the Cane Creek DB Air IL, the Float X2 Factory stands out for its high level of adjustability and refined damping controls. The Fox shock is particularly known for its smooth, consistent performance across a wide range of terrain. Riders who prioritize maximum adjustability and fine-tuning will appreciate the Float X2’s capabilities, while those looking for a more straightforward shock might prefer simpler models like the RockShox Monarch.
Compatibility with Other Drivetrain Components
The Float X2 Factory rear shock is designed to work seamlessly with most modern mountain bike drivetrains. However, it is essential to check compatibility with your bike frame and suspension design. Always consult your bike frame’s specifications to ensure the shock’s eyelet and travel length are a perfect fit for your bike. Additionally, make sure the shock’s air pressure range aligns with your bike’s intended use, whether it’s cross-country, all-mountain, or enduro riding.
