- Small flathead screwdriver
- Needle-nose pliers
- Soft cloths or rags
- Suspension fluid (Specific to Future Shock E100 [paid link])
- Fork oil (per manufacturer recommendations)
- Teflon tape
- Shock pump
- Replacement seals and o-rings
- Bearing grease (specific for suspension use)
Disassembling the Future Shock E100 Fork
Step 1: Prepare Your Work Area
Before beginning the disassembly process, ensure you have a clean, well-lit workspace. Lay down a soft cloth or towel to protect your fork’s surfaces from scratches. Organize your tools for easy access.
Step 2: Remove the Fork from the Bike
To begin, remove the front wheel from your bike, followed by the brake calipers and the fork from the headset. Use a 5mm hex wrench to detach the fork from the frame. Take note of how the components are assembled so that reassembly is straightforward.
Step 3: Remove the Compression Damper Assembly
Using a 6mm hex wrench, unscrew the compression damper assembly from the top of the fork. This will typically involve unscrewing a cap or bolt that holds the assembly in place. Be cautious when removing the damper to avoid damaging the internal parts.
Step 4: Extract the Lower Leg Assembly
Once the compression damper is removed, place the fork in a vise with soft jaws to prevent damage. Carefully remove the lower leg assembly by loosening the appropriate bolts. Pay close attention to any oil or grease that may be released during this step.
Step 5: Remove the Air Shaft and Spring
With the lower leg assembly removed, you can access the air shaft and spring. Use needle-nose pliers to gently pull the air shaft out of its casing. Take care not to bend or damage the shaft, as it is a crucial component in controlling air pressure within the fork.
Cleaning and Inspection
Step 6: Clean the Fork Components
Using a soft cloth, thoroughly clean all components of the fork. Remove any old grease, dirt, or suspension fluid that may have accumulated. Avoid using harsh chemicals, as they may damage seals or other parts. For better results, consider using a suspension-specific cleaner to ensure proper maintenance.
Step 7: Inspect for Wear or Damage
Inspect the fork’s components, including the stanchions, seals, and air shaft. Look for signs of wear, such as scratches or gouges on the stanchions, which could affect performance. If any seals appear cracked or worn, replace them immediately. Check for any damage to the air shaft or damper assembly that could prevent proper functioning.

Step 8: Replace Worn Seals and O-rings
Using the appropriate tools, replace any worn or damaged seals and o-rings. It is crucial to use high-quality replacement parts to ensure a proper seal and prevent leaks. Apply a small amount of suspension-specific grease to the seals before installation to ensure smooth operation and reduce wear over time.
Step 9: Reinstall the Air Shaft and Spring
Once the seals and o-rings are replaced, reinstall the air shaft and spring into their respective housings. Ensure the air shaft is properly seated, and the spring is aligned within the fork. This is crucial for maintaining correct air pressure and ensuring smooth travel during compression and rebound.
Step 10: Fill the Fork with Suspension Fluid
Using the manufacturer’s recommended suspension fluid, fill the fork with the appropriate amount of oil. This is critical for the smooth functioning of the damper and lubrication of the moving parts. Follow the exact specifications in terms of fluid type and amount to ensure optimal performance.
Step 11: Reassemble the Lower Leg and Damper Assembly
Carefully reassemble the lower leg assembly and damper unit back onto the fork. Tighten all bolts to the manufacturer’s torque specifications. Use a torque wrench [paid link] to ensure the components are tightened to the correct torque values to prevent damage or improper functioning.
Step 12: Reinstall the Compression Damper
Once the lower leg assembly is in place, reinstall the compression damper assembly into the top of the fork. Tighten it securely with the 6mm hex wrench, ensuring that it is aligned properly. Check that the damper’s adjusters are functioning smoothly and that the fork is ready for tuning.
Reassembling the Fork
Step 13: Reattach the Fork to the Bike Frame
Now that the fork is rebuilt, it’s time to reinstall it onto your bike. Align the fork’s steerer tube with the headset, and secure it back onto the bike using the headset compression ring and top cap. Ensure that the fork is seated properly and that the headset is tight without any play.
Step 14: Reinstall the Brake System and Front Wheel
Reattach the front brake calipers and any necessary brake components. Then, install the front wheel, ensuring the quick release or thru-axle is securely tightened. Ensure that the wheel is properly centered in the fork dropouts.
Step 15: Set Air Pressure and Tune the Fork
Use a shock pump to adjust the air pressure in the fork according to your rider weight and preferences. Start by setting the air pressure to the recommended baseline for your weight and adjust it for personal comfort. Test the suspension by compressing the fork a few times to check for smoothness and consistent performance.
Troubleshooting Common Issues
Fork Sticking or Rough Travel
If you experience rough or sticky fork travel, check for dirt or debris on the stanchions. Clean the fork thoroughly and inspect the seals for wear. Applying a small amount of suspension oil to the stanchions can sometimes help with smoother movement.
Poor Rebound Control
If the rebound control feels sluggish or overly fast, ensure the rebound damper is correctly installed and filled with the proper amount of oil. If the oil level is low or the damper is damaged, it can result in poor rebound performance.
Air Leaks
If you notice that the fork is losing air pressure, it’s likely due to a damaged seal or an issue with the air shaft. Replace any worn seals and recheck the air pressure after the rebuild. Be sure that all components are properly sealed during reassembly.
Customization and Performance Optimization
Fine-Tuning Compression and Rebound
To optimize the fork’s performance, adjust the compression and rebound settings to match your riding style. Adjusting the compression damping will control how the fork responds to impacts, while tuning the rebound allows you to fine-tune how quickly the fork returns after compression. Experiment with both settings to achieve the ideal balance of comfort and performance.
Adjusting Air Pressure
Adjusting the air pressure to suit your riding weight and preferred suspension feel can drastically improve the bike’s handling. If you’re riding on smoother terrain, lower air pressure may provide a more comfortable ride, while higher pressure will improve performance on rough trails.
Compatibility with Other Drivetrain Components
The Future Shock E100 suspension fork is designed to be compatible with a wide range of drivetrain components. However, be sure to check the fork’s axle and headset compatibility before pairing it with specific frames and components. Some specialized frames may require specific adapters to ensure the fork is properly installed.
Rebuilding your Future Shock E100 suspension fork can significantly extend the life of the fork and improve the performance of your bike. By following this guide carefully, you’ll be able to enjoy smoother, more responsive suspension for your rides, ensuring both comfort and control on your cycling adventures.
