  • 5mm and 6mm Allen wrenches [paid link]
  • Soft rag or cloth
  • Suspension oil (manufacturer recommended)
  • Clean container for draining
  • T25 and T30 Torx drivers
  • Isopropyl alcohol for cleaning
  • Silicone-based lubricant

Installation of the McLeod Rear Shock

Installing the McLeod rear shock on your bike requires precision to ensure it operates correctly. Follow these steps for a safe and effective installation:

  1. Prepare the Frame and Shock Mounts: Before you begin the installation, ensure the frame’s shock mounts are clean and free from debris. Use a rag to wipe them down and ensure the mounting holes are clear.
  2. Install the Shock: Position the McLeod rear shock into the frame’s designated shock mount. Make sure the shock is aligned properly with the mounting holes.
  3. Secure the Shock: Using the appropriate-sized Allen wrenches [paid link], install the bolts into the shock mounts. Be sure to tighten them to the manufacturer’s specified torque setting. This is typically around 10-12 Nm for most models. Check both the top and bottom bolts for tightness.
  4. Check Shock Movement: After installation, compress the shock a few times to ensure it moves freely and that there is no binding. This step also ensures that the shock is properly aligned.
  5. Set Up Air Pressure: Attach the shock pump to the Schrader valve on the shock. Refer to the manufacturer’s guidelines for the recommended pressure based on rider weight and intended use. Ensure the pressure is adjusted properly for a smooth ride.

Adjustment and Tuning for Performance

The McLeod rear shock offers several tunable features to improve comfort and performance based on your riding style. The main adjustments include rebound damping, compression damping, and air pressure.

Rebound Damping

Rebound damping controls the rate at which the shock returns to its original position after compressing. This setting is essential for ensuring that the shock doesn’t rebound too quickly, which can lead to loss of control, or too slowly, which can make the ride feel sluggish.

  • To adjust the rebound: Locate the rebound adjuster knob (usually found on the lower body of the shock). Turn it clockwise to slow down the rebound and counterclockwise to speed it up. A good starting point is to set the rebound damping to the middle of the adjustment range.
  • Fine-tuning: If you find that the shock is not returning fast enough or too quickly, make small adjustments, riding a short section of trail in between to gauge the change.

Compression Damping

Compression damping regulates how quickly the shock compresses when it hits a bump or obstacle. Proper adjustment can greatly affect how the shock performs on various terrains, providing a balanced mix of sensitivity and support.

  • To adjust compression damping: Find the compression adjuster knob (typically located on the top of the shock). Turn it clockwise to increase damping for a firmer ride and counterclockwise to decrease damping for a more plush feel.
  • Fine-tuning: Start with a medium setting and experiment depending on your terrain. More compression damping is beneficial for aggressive downhill riding, while less is preferable for smoother, cross-country trails.

Air Pressure

Air pressure is one of the most critical settings for the McLeod rear shock, directly affecting the shock’s performance and responsiveness.

  • To adjust air pressure: Use a shock pump to adjust the pressure through the Schrader valve. A general guideline is to set the pressure according to the rider’s weight and the type of riding you plan to do. For example, lighter riders may need less pressure, while heavier riders will require more.
  • Fine-tuning: Ensure the air pressure allows the shock to cycle through its full travel without bottoming out too frequently. Test the bike and make adjustments after short rides.

Maintenance Tips for Longevity

To keep your McLeod rear shock in top shape, regular maintenance is essential. Here are some crucial steps for maintaining the shock:

  1. Cleaning the Shock: After each ride, use a clean rag to wipe down the shock’s stanchion tubes and seals. Be sure to remove any mud or debris that could cause damage over time. If necessary, use a small amount of isopropyl alcohol to clean the components.
  2. Check for Leaks: Inspect the shock regularly for signs of oil leakage. If you notice oil around the seals or mounting points, it may indicate the shock requires servicing. Leaks can affect shock performance and may require a rebuild.
  3. Lubricate the Seals: Use a silicone-based lubricant to keep the shock’s seals in good condition. Apply a small amount to the seals and stanchions after cleaning to ensure smooth travel.
  4. Inspect for Wear: Regularly check the shock for any signs of wear, such as damaged mounting hardware or worn-out seals. If the shock feels less responsive or makes unusual noises, it may require internal servicing.

Troubleshooting Common Issues

Loss of Air Pressure

If your McLeod rear shock is losing air pressure, it could indicate a leak. Inspect the Schrader valve and the seals for any visible damage. In some cases, the shock may need a complete rebuild to resolve internal issues.

Rebound or Compression Problems

If the shock is not responding properly to adjustments, the damping circuits may be clogged or damaged. This is a more complex issue and may require professional servicing.

Unusual Noises

Strange noises from the shock can be caused by dirt or debris in the shock body, or dry seals. Cleaning the shock and applying lubricant should resolve most noise-related issues. If the noise persists, a deeper inspection of the internal components may be necessary.

Customizing Your McLeod Rear Shock for Better Performance

To optimize your riding experience, you may want to fine-tune your McLeod rear shock further. Here are some customization tips:

  • Custom Tune Settings: Work with your local bike shop to determine if a custom tune is available for your shock. Custom tuning can modify the internal valving to better suit your specific riding style and weight.
  • Spring Rate Adjustments: If you find the shock too soft or too stiff, you may want to adjust the spring rate. Consider switching to a different air spring or adding additional air volume spacers to tweak the spring curve.
  • Shock Service: Regular shock services, including oil and seal changes, will help maintain a smooth and consistent ride. Consult the McLeod owner’s manual for recommended service intervals.

Comparison with Similar Models

When choosing a rear shock, it’s essential to compare the McLeod with other popular models to determine if it’s the right fit for your needs.

  • McLeod vs. Fox DPX2: While both shocks offer excellent performance, the McLeod is known for its more progressive damping, making it a great choice for aggressive riders who need more control on rough terrain. The Fox DPX2, on the other hand, offers a more linear damping curve, making it better for cross-country riders seeking a smoother, more plush ride.
  • McLeod vs. RockShox Super Deluxe: The McLeod offers a slightly more adjustable air spring, while the RockShox Super Deluxe is designed for riders looking for a more customizable compression setting. Depending on your riding preferences, either option could provide optimal performance.

Compatibility with Other Drivetrain Components

The McLeod rear shock is designed to work seamlessly with most modern mountain bike drivetrains. However, compatibility with certain suspension designs and frame geometries may vary. Be sure to consult with the manufacturer’s recommendations and your bike shop to ensure the McLeod rear shock is compatible with your bike’s other components.

While it works well with most common setups, including SRAM and Shimano drivetrains, it’s always best to double-check the shock’s specifications and confirm that it suits your frame and riding style. Compatibility with other drivetrain components can affect performance, so choosing the right rear shock based on your needs is crucial.

Conclusion

Maintaining and adjusting your McLeod rear shock can drastically improve your bike’s performance, providing you with a smooth and controlled ride. By following the steps in this guide for installation, adjustments, maintenance, and troubleshooting, you can ensure your shock continues to perform at its best. Customizing your setup to match your riding style will enhance your experience, whether you’re hitting technical trails or enjoying a long ride. Keep your McLeod rear shock well-maintained, and it will continue to provide exceptional performance for years to come.
