Tools Required

  • 8mm hex wrench
  • 5mm hex wrench
  • Torque wrench [paid link] (up to 10 Nm)
  • 10mm open-ended wrench
  • Phillips screwdriver
  • Small flathead screwdriver
  • Suspension fluid (Specialized recommended)

Disassembling the Future Shock E100 Fork

Before starting the service process, ensure that your bike is in a secure position on a bike stand [paid link], and you have all the required tools. Disassembling the Future Shock E100 fork is the first step in performing any maintenance task.

  1. Remove the Front Wheel: Begin by removing the front wheel. This gives you access to the fork and suspension system.
  2. Remove the Fork from the Frame: Use your 8mm hex wrench to loosen and remove the two bolts securing the fork to the frame. You may need to use the 10mm open-ended wrench to remove the fork if necessary.
  3. Remove the Compression Damper: The Future Shock E100 features an adjustable compression damper. To access this, remove the fork cap at the top of the suspension using the 5mm hex wrench. You can then carefully pull out the compression damper.

Cleaning and Inspection

Once the fork has been removed, the next step is to clean all parts thoroughly. Proper cleaning not only removes dirt and debris but also allows for a detailed inspection of the components.

  1. Clean the Fork Components: Use a clean rag to wipe down all fork parts. Pay special attention to the stanchions and lower legs, ensuring that no dirt or grime is left behind.
  2. Inspect for Wear and Tear: Carefully inspect the stanchions, bushings, and seals for any signs of wear or damage. Check for any scoring on the stanchions and look for cracks or any wear on the seals. If the seals are worn or cracked, it’s important to replace them with a new seal kit.
  3. Check the Damper: Examine the damper for any oil leaks or damage. If you notice any, this could be an indication of internal damage that requires professional attention.

Replacing the Suspension Fluid

Changing the suspension fluid in your Future Shock E100 fork is an essential part of regular maintenance. This fluid lubricates the internals of the fork and helps ensure smooth operation.

  1. Drain the Old Fluid: Use a small container to catch the old suspension fluid. After removing the fork cap and damper, tilt the fork and allow the fluid to drain completely.
  2. Clean the Reservoir: Once the fluid has drained, clean the internal reservoir of the fork with a clean rag. Ensure that no debris or old fluid remains.
  3. Refill the Fork with New Fluid: Pour the recommended suspension fluid into the fork, following the manufacturer’s instructions on the correct amount. The Future Shock E100 typically requires around 100-120ml of fluid, depending on rider weight and riding conditions.

Reassembling the Fork

After cleaning and replacing the suspension fluid, it’s time to reassemble the fork. Be careful to ensure that all parts are correctly installed and properly torqued to avoid issues.

  1. Install the Damper: Insert the compression damper back into the fork, ensuring it is seated properly.
  2. Reattach the Fork Cap: Once the damper is in place, reinstall the fork cap. Use your 5mm hex wrench to tighten it, ensuring it is secure but not over-tightened.
  3. Install the Seals: If you’ve inspected the seals and found them to be worn, replace them with new seals. Grease the new seals lightly before installation to ensure a smooth fit.
  4. Check the Stanchions and Bushings: Slide the stanchions back into the lower legs and ensure they move smoothly. If any resistance is felt, check that the bushings are properly seated and lubricated.

Adjusting the Fork Settings

After reassembling the fork, you’ll need to adjust the settings to your preferred ride quality. The Future Shock E100 features adjustable compression, which you can fine-tune based on your weight and riding style.

  1. Set the Compression: Use the adjuster at the top of the fork to set the compression to your desired level. A stiffer compression is ideal for riders who prefer more control on smoother roads, while a softer setting is better suited for those seeking more comfort on rougher terrain.
  2. Test the Suspension: Before reinstalling the fork, it’s advisable to test the suspension’s functionality. Compress the fork a few times to ensure it feels smooth and consistent. Check for any signs of air bubbles or erratic movement, which could indicate air in the system or issues with the damper.

Reinstalling the Fork

Once everything is adjusted, it’s time to reinstall the fork back onto the bike.

  1. Install the Fork: Slide the fork back into the frame and secure it using your 8mm hex wrench to tighten the bolts. Ensure the fork is aligned correctly with the frame.
  2. Reinstall the Front Wheel: Carefully reinstall the front wheel and ensure it is properly aligned with the fork. Tighten the quick release or axle nuts accordingly.

Troubleshooting Common Issues

While servicing the Future Shock E100 fork, you may encounter a few common issues that can be easily resolved.

Fork Sticking or Jumpy Movement

  • Cause: This could be caused by insufficient suspension fluid or air trapped in the damper.
  • Solution: Ensure that you’ve properly drained and refilled the suspension fluid. Try bleeding the damper to remove any trapped air.

Leaking Fluid

  • Cause: Leaking fluid can be a result of worn seals or over-tightening the fork cap.
  • Solution: Inspect the seals and replace them if damaged. Be careful not to overtighten the fork cap when reinstalling.

No Suspension Travel or Inconsistent Travel

  • Cause: This could indicate an issue with the damper or a lack of fluid inside the fork.
  • Solution: Recheck the suspension fluid levels and ensure the damper is functioning properly. If the problem persists, consider taking the fork to a professional for further inspection.
