Understanding Your Mattoc Pro Suspension Fork
Before performing any service, it’s essential to understand the core components of the Mattoc Pro suspension fork. This fork is designed with a variety of features that enhance its performance, including the Manitou’s IRT (Independent Reach Adjust) system, which provides easy compression tuning. It is a highly customizable fork, offering travel adjustments, lockout features, and precise tuning options for different riding conditions.
Step 1: Preparing the Fork for Servicing
Begin by removing the fork from the bike. This can be done by loosening the axle and brake caliper and detaching the fork from the headset. Once the fork is removed, securely place it on a clean, stable surface to prevent any damage.
Step 2: Removing the Fork’s Air Spring
To access the internal components, the air spring must first be removed. Start by unscrewing the top cap of the fork using a 6mm Allen wrench [paid link]. Carefully release any air pressure using the valve on the top of the fork. It’s important to follow the manufacturer’s instructions regarding pressure levels for safe handling.
Once the air pressure is released, remove the air spring assembly by unscrewing any additional bolts. Be cautious as some models may have additional retainers that need to be disengaged.
Step 3: Draining Old Suspension Fluid
Next, you’ll need to drain the old suspension fluid. Position the fork so that the lower legs are pointing down. Loosen the lower leg bolts with a 5mm Allen wrench [paid link] and carefully remove the lower legs. Be sure to capture the draining fluid in a bowl or container. At this stage, you may also want to inspect the condition of the fluid—if it’s dirty or contains visible debris, a full fluid replacement is recommended.
Once the fluid has fully drained, use a clean rag to wipe out any excess residue inside the fork. It’s important to clean the interior thoroughly to prevent contamination with old, degraded fluid.
Step 4: Inspecting and Replacing Seals
The seals on the Mattoc Pro are crucial for keeping dirt and water out of the fork’s internals. If your fork shows signs of leaking oil or if the seals feel brittle, it’s time to replace them. Use a small brush to clean the fork’s stanchions before removing the seals.
Use the appropriate seal replacement tool to remove the old seals carefully. When installing new seals, ensure they fit snugly into the seal grooves and that no dirt or debris enters the fork during the process. Applying a small amount of Manitou-specific grease to the seals can help with installation and ensure a smooth action.
Step 5: Adding New Suspension Fluid
After replacing the seals, it’s time to add fresh suspension fluid to the fork. Using a suspension fluid syringe or pump, carefully inject the recommended amount of fluid into the fork’s lower legs. Ensure that you use the correct type and amount of fluid specified in the user manual, as improper fluid can negatively impact the fork’s performance.
Once the fluid is added, reattach the lower legs and secure them using the appropriate torque values. It’s essential to torque the bolts to the specifications listed in the manual to prevent over-tightening or under-tightening.
Step 6: Reassembling the Air Spring
Now that the fork is cleaned, the seals are replaced, and the suspension fluid is added, you can reassemble the air spring. Install the air spring back into the fork and secure it in place by tightening the necessary bolts. Reinstall the top cap and ensure that the air spring is set to the correct pressure. Follow the manufacturer’s guidelines for pressure settings based on your weight and riding style.
Step 7: Adjusting the Fork
With the fork reassembled, you can adjust the settings for your preferred riding style. The Mattoc Pro fork includes a range of adjustments, such as rebound and compression settings. Adjust these settings based on your riding preferences and terrain. If you have the IRT system, you can fine-tune the compression for specific conditions, such as downhill or cross-country riding.
Troubleshooting Common Issues
1. Fork Feeling Stiff or Not Responsive
If the fork feels stiff or unresponsive, it may be due to old or insufficient suspension fluid. In this case, try draining the fluid and replacing it with fresh fluid to restore the fork’s performance. Additionally, ensure that the air spring is properly pressurized.
2. Leaking Oil or Air
Leaking oil or air can indicate damaged seals or O-rings. Inspect the seals for wear and replace them as necessary. Make sure the air spring is properly sealed and tightened during reassembly.
3. Poor Rebound Control
If you notice poor rebound control, check the rebound adjustment settings. It’s also worth verifying the fork’s internal components, such as the damper, for any signs of damage or wear.
Step 8: Testing the Fork
After servicing your Mattoc Pro suspension fork, it’s important to test it to ensure it’s functioning properly. Reinstall the fork onto your bike and test the suspension action by compressing the fork and checking for smoothness. Make adjustments as needed to fine-tune the rebound and compression settings.
Customization and Optimization
The Mattoc Pro fork offers a variety of customization options to enhance performance. Riders can adjust the air spring pressure for different weight categories, tweak compression damping for improved control on rough terrain, and dial in the rebound settings for a smoother ride.
For those seeking an optimized performance, consider experimenting with different travel settings or tuning the IRT system for specialized riding needs. Regular maintenance of the fork, including proper fluid changes and seal replacements, will keep the fork operating at its best for years to come.
Comparing Mattoc Pro with Other Models
When compared to other high-performance suspension forks in the same category, the Mattoc Pro offers a unique balance of adjustability and control. Unlike some competing models, the IRT system in the Mattoc Pro provides highly customizable compression damping that can be tuned for specific riding conditions, making it ideal for riders who frequently change terrains or riding styles.
If you are deciding between the Mattoc Pro and another fork, such as the RockShox Pike or Fox 36, consider the Mattoc Pro’s flexibility in tuning and its overall value for the price. While the RockShox Pike is known for its robustness in aggressive riding, and the Fox 36 is often praised for its stiffness and precision, the Mattoc Pro holds its ground with superior adjustability and smooth performance.
Compatibility with Other Drivetrain Components
The Mattoc Pro suspension fork is compatible with a wide range of drivetrain components, particularly those designed for mountain and enduro bikes. It pairs well with Manitou’s own components but is also compatible with popular brands like SRAM and Shimano. Ensure that your bike’s headset, axle, and brake mounts are compatible with the fork’s specifications before installation.
Proper compatibility ensures that the fork functions optimally, and it also helps prevent premature wear or damage to both the fork and other components.
Servicing the Mattoc Pro suspension fork at home is a straightforward process, as long as you follow the proper steps and use the right tools. Regular maintenance will not only enhance performance but also extend the lifespan of your fork, keeping your ride smooth and reliable across any terrain.
