Installation of the Fox DPX2 Factory Rear Shock

Installing the Fox DPX2 Factory rear shock correctly is essential to ensure optimal performance and longevity. Here’s a step-by-step guide to assist with installation:

1. Remove the Old Shock:
   • Begin by safely lifting the bike using a work stand or an appropriate support.
   • Use a wrench or Allen key to remove the fasteners securing the existing rear shock to the bike frame.
   • Remove the shock and set it aside for inspection or replacement.
2. Prepare the New Fox DPX2 Factory Shock:
   • Unbox the shock carefully, ensuring all parts, such as mounting hardware and air caps, are intact.
   • Confirm that the shock is the correct size and configuration for your bike frame.
3. Install the New Shock:
   • Position the shock in the mounting area of the frame. Ensure it aligns properly with the shock mount holes.
   • Tighten the mounting bolts to the manufacturer’s recommended torque settings.
   • Be cautious not to overtighten, as this can damage the frame or shock.
4. Install the Air Canister:
   • Attach the air valve to the shock if necessary, ensuring a secure and leak-free connection.
   • Use a shock pump to add air to the shock according to your weight and riding style.
5. Check for Proper Installation:
   • Inspect all hardware and ensure the shock is securely fastened.
   • Test the rear suspension movement by compressing and rebounding the shock, making sure there is no binding or excessive play.

Adjustment and Tuning of the DPX2 Factory Rear Shock

The DPX2 Factory rear shock offers a range of adjustments that can be fine-tuned for different riding conditions and rider preferences. These adjustments help optimize comfort, control, and efficiency. Key adjustments include:

Air Pressure Setup

• Preload Adjustment: Adjust the air pressure in the shock to match your weight and riding style. Start with the recommended baseline, then fine-tune based on the sag measurement. Generally, the correct sag is about 25-30% of the total shock stroke.
• Rebound Control: The DPX2 features an adjustable rebound setting that controls the speed at which the shock returns after compression. Adjust the rebound based on terrain; slower rebound is preferred for rougher trails, while faster rebound is better for smoother trails.

Compression Settings

• Low-Speed Compression: This adjuster controls the shock’s damping during slow compressions, such as when pedaling or descending at lower speeds. Turning the dial clockwise increases compression, making the shock firmer and less active.
• High-Speed Compression: This adjuster affects the shock during rapid, high-force compressions, such as landing drops or hitting large bumps. Adjust the dial to control the shock’s response to high-impact terrain.

Volume Spacers

• The DPX2 Factory comes equipped with the ability to add or remove volume spacers inside the air chamber. Adjusting the volume spacers helps change the shock’s progression. More spacers will increase mid-stroke support, while fewer spacers provide a more linear stroke. This adjustment can be crucial for tailoring the ride feel to your preferences.

Maintenance and Care of the DPX2 Factory Rear Shock

Proper maintenance is vital to keep your Fox DPX2 Factory rear shock performing at its best. Regular servicing ensures the shock operates smoothly and extends its lifespan.

Regular Cleaning

• After each ride, especially in muddy or dusty conditions, clean the shock with a damp cloth. Avoid using a high-pressure washer, as it can force water and debris into sensitive areas of the shock.
• Clean the shock’s air valve and mounting hardware to prevent dirt accumulation, which can affect performance.

Lubrication

• Periodically lubricate the shock’s stanchion tube with suspension-specific oil to ensure smooth movement. Apply a small amount of oil and work the shock through its travel to evenly distribute it.

Air Canister Maintenance

• Over time, air seals can wear, leading to air leaks. To maintain a proper air seal, periodically check the air pressure and inspect the shock for any signs of leaks. If necessary, replace the seals following Fox’s recommended intervals.

Full Service

• A full shock service includes disassembling the shock to inspect and clean internal components, replace worn seals, and refill it with fresh oil. Fox recommends a full service every 100 hours of use or annually, whichever comes first.

Troubleshooting Common DPX2 Factory Rear Shock Issues

Even with meticulous care, issues can arise with your Fox DPX2 Factory rear shock. Here are some common problems and troubleshooting tips:

Shock Does Not Hold Air

• Cause: A common issue is air leakage due to damaged seals or improper valve connections.
• Solution: Inspect the air valve and surrounding area for any signs of damage. If the valve or seals are worn, replace them. Ensure the shock pump is properly connected and not leaking.

Excessive Rebound or Compression

• Cause: Incorrect rebound or compression settings may result in overly slow or fast rebound.
• Solution: Check your current settings and adjust them according to your riding preferences. Remember to fine-tune both low-speed and high-speed compression settings for optimal results.

Noise or Creaking from the Shock

• Cause: Noise can occur from dirt, debris, or lack of lubrication in the shock’s mounting hardware.
• Solution: Clean the shock and mounting area, ensuring all parts are free from debris. Apply grease to the shock eyelets and bolts where necessary to prevent squeaks.

Customization for Better Performance

The DPX2 Factory rear shock is designed with versatility in mind, allowing for customization to suit various rider preferences and conditions. Key customizations include:

Adjusting Volume Spacers

• Riders can customize the shock’s feel by adjusting the internal volume spacers. This allows for better control over mid-stroke support, giving riders the ability to fine-tune their shock for different terrain types, whether it’s aggressive downhill or technical cross-country riding.

Changing Air Pressure Based on Terrain

• Adjusting air pressure according to the terrain is essential for maintaining optimal performance. For rocky and technical trails, a higher air pressure may be beneficial for maintaining better control, while smoother trails might require less air pressure for a softer, more plush feel.

Comparing the Fox DPX2 Factory with Other Rear Shocks

When considering the DPX2 Factory, it’s important to compare it with other similar models in the market. One common comparison is with the Fox Float X2.

• Fox DPX2 Factory: Offers excellent adjustability with both low and high-speed compression settings, making it ideal for riders who need fine-tuned suspension for aggressive terrain. Its external adjustments and sealed air spring are optimized for versatility and consistency in varied conditions.
• Fox Float X2: The Float X2 provides a more linear feel and greater damping precision, making it suitable for downhill and enduro riders who need extreme performance under aggressive conditions. However, it has a slightly more complex setup than the DPX2 Factory, which may be challenging for beginners.

Both shocks provide top-tier performance, but the DPX2 Factory may be more suitable for riders who value a balance between ease of use and customizable options for varied riding styles.

Compatibility with Other Drivetrain Components

The Fox DPX2 Factory rear shock is highly compatible with a wide range of drivetrain components. It is particularly well-suited for bikes with modern suspension designs, including those using full-suspension frames with a focus on progressive linkage systems. Ensure that the rear shock’s eyelet dimensions and mounting hardware are compatible with your bike frame.

When selecting drivetrain components, particularly rear derailleurs, ensure they match the suspension settings. The DPX2 Factory works well with high-end drivetrains like Shimano XTR or SRAM XX1, providing smooth performance in rough conditions.

Conclusion

The Fox DPX2 Factory Rear Shock is an advanced suspension component designed for riders who demand top-notch performance and adjustability. By understanding how to install, adjust, maintain, and troubleshoot this shock, riders can optimize their bike’s handling and comfort across various terrains.
