Installation of the Float X Factory Rear Shock

Step 1: Prepare the Bike Frame

Before installing the Float X Factory rear shock, make sure your bike frame is clean and free of debris. The mounting points should be dry and free from grease. This ensures a secure fit and helps prevent any damage to the shock or frame during installation.

Step 2: Position the Shock

Align the eyelets of the Float X shock with the mounting points on your frame. The shock’s eyelets must match the frame’s attachment points, ensuring a snug fit without any unnecessary movement.

Step 3: Install the Mounting Hardware

Once the shock is aligned, install the appropriate mounting hardware. Make sure to use the correct bolts for your bike’s frame. Tighten the hardware using a 6mm Allen wrench [paid link], but be careful not to overtighten, as this could damage the shock or the frame.

Step 4: Check the Shock’s Position

Ensure that the shock is mounted securely and does not move. If you notice any gaps or looseness, check the mounting hardware again to ensure it is seated properly.

Step 5: Pump the Shock to the Correct Pressure

Using a Fox shock pump, adjust the air pressure of the Float X rear shock. Refer to the manufacturer’s recommended pressure settings for your rider weight, riding style, and shock settings. Make small adjustments, adding or releasing air gradually, and check the shock’s sag once it is inflated to ensure a proper setup.

Adjusting the Float X Factory Rear Shock

The Float X Factory rear shock comes equipped with several adjustable features that allow you to fine-tune your ride based on terrain, riding style, and personal preference. Here’s how to adjust the shock to suit your needs.

Rebound Adjustment

Rebound adjustment controls how quickly the shock returns to its original position after compressing. Turning the rebound dial clockwise will slow the rebound, while turning it counterclockwise will speed it up. Start with the factory setting and make small adjustments, testing your ride between changes to find the ideal rebound for your riding style.

Compression Adjustment

The Float X features two compression settings: open and firm. The open setting allows the shock to react more freely to terrain, while the firm setting provides more resistance. Adjust the compression settings based on the type of riding you’re doing. For smoother trails, the open setting works best, while more technical trails may benefit from a firmer compression setting.

Air Spring Pressure

As previously mentioned, adjusting the air pressure is critical for achieving the proper shock sag. A general rule is that the shock should sag around 25-30% of its total travel when you are on the bike. Too much air pressure can lead to a harsh ride, while too little can result in bottoming out. Refer to the manufacturer’s guidelines to find the best starting point for your weight and riding style.

Maintenance of the Float X Factory Rear Shock

Regular maintenance of your Float X Factory rear shock is essential to ensure optimal performance and longevity. Here are some basic maintenance tasks to keep your shock functioning at its best.

Cleaning and Inspection

After each ride, it’s important to clean the shock to remove any dirt, debris, or water that might have accumulated. Use a clean, lint-free cloth and isopropyl alcohol to gently wipe the shock’s exterior. Inspect the shock for any visible signs of damage, such as scratches or leaks. Check the eyelets and mounting hardware to ensure they are still secure.

Lubrication

Periodically, you should lubricate the shock’s mounting points with suspension-specific grease to ensure smooth operation. This will help prevent wear on the shock’s mounting hardware and frame.

Service Intervals

Fox recommends having the Float X rear shock serviced every 100 hours of riding or annually, whichever comes first. This service includes an oil change, air spring inspection, and a full rebuild if necessary. Regular servicing ensures that the shock is in top condition and prevents issues that could arise from neglect.

Troubleshooting Common Set-Up Issues

While the Float X Factory Rear Shock is a high-quality component, there are some common issues that riders might encounter. Below are some troubleshooting steps to help address these issues.

Shock Bottoming Out

If you notice that the shock is bottoming out frequently, it could be due to improper air pressure, excessive rider weight, or incorrect compression settings. First, check your air pressure and make sure it matches the manufacturer’s recommendations. If the air pressure is correct, adjust the compression settings to provide more resistance, or consider adding more volume to the air spring.

Poor Rebound Performance

If the rebound is too slow or too fast, the first thing to check is the rebound adjustment knob. If it’s set too high or too low, it could cause instability in the shock’s performance. Adjust the rebound dial and test the ride until you find the optimal setting. If the rebound is still inconsistent, the shock may need servicing.

Noisy Shock

A noisy shock could indicate that there is dirt or debris trapped in the shock’s moving parts. Clean the shock thoroughly, paying special attention to the seals and moving parts. If the noise persists, the shock may require a full rebuild.

Customization and Optimization for Better Performance

One of the standout features of the Float X Factory Rear Shock is its customizable tuning options. These can be adjusted for better performance, whether you’re a competitive racer or a casual rider. Here are some ways to further optimize your shock setup:

Fine-Tuning Compression and Rebound

Use a shock pump to adjust the air pressure and achieve the proper sag, then fine-tune the rebound and compression settings to match your riding style. For aggressive riders, stiffening up the compression and slowing the rebound may provide better control. For more technical terrain, softer settings may improve comfort and performance.

Volume Spacers

The Float X allows for the addition of volume spacers in the air spring to adjust the shock’s progression. Adding volume spacers will make the shock ramp up more quickly as it compresses, which can be beneficial for riders who prefer a more progressive feel. Removing spacers softens the ride, allowing for more plushness in the mid and end stroke.

Comparing the Float X Factory Rear Shock with Similar Models

While the Float X Factory is one of Fox’s best rear shocks, it’s important to compare it with similar models to see how it stacks up.

• Fox Float DPX2: The DPX2 offers a more affordable price point with fewer adjustment options compared to the Float X. The DPX2 is ideal for riders seeking a more straightforward setup but may not provide the same level of customization as the Float X.
• Fox DHX2: The DHX2 is more suited for downhill riders. It features a coil spring instead of an air spring, offering a more consistent feel and better performance on aggressive terrain, but it’s heavier and less tunable than the Float X.
• RockShox Super Deluxe Ultimate: A strong competitor to the Float X, the Super Deluxe offers similar performance but is often considered slightly more sensitive in terms of compression adjustments. It also includes a lockout feature, which some riders prefer for climbing.

Compatibility with Other Drivetrain Components

The Float X Factory rear shock is compatible with most modern bike frames that use standard mounting hardware. However, compatibility with other drivetrain components—such as the rear derailleur, cassette, and chain—should be considered when choosing your suspension setup. The Float X’s performance benefits can be maximized when paired with a well-matched drivetrain, ensuring that the shock’s capabilities are not hindered by other components.

In particular, it is essential to ensure that the rear shock’s travel and geometry complement your bike’s frame and drivetrain for optimal handling and smooth gear transitions.
