Keeping your bike’s forks clean and maintained is essential for optimal performance and longevity. Over time, dirt, dust, and debris can accumulate inside the fork lowers, affecting the fork’s function and leading to potential damage. Cleaning the inside of your fork lowers is a simple process that can greatly improve the performance and lifespan of your bike’s suspension.
To begin, you will need a few basic tools and materials. These include a soft brush or toothbrush, clean rags or paper towels, isopropyl alcohol or suspension fluid, and a fork oil seal driver. It’s also helpful to have a workstand or something to secure your bike in an upright position.
Start by removing the front wheel of your bike and securing it in the workstand. Next, locate the allen bolts that hold the fork lowers in place and carefully loosen them, allowing the fork lowers to slide down. Take care not to damage the fork seals during this process, as they are essential for preventing dirt and debris from entering the internals of the fork.
Once the fork lowers are removed, use the soft brush or toothbrush to carefully clean out any dirt, dust, or debris inside. Be thorough but gentle to avoid scratching or damaging any internal components. After cleaning, use the isopropyl alcohol or suspension fluid to wipe down the insides of the fork lowers, removing any remaining dirt or residue.
After the fork lowers are clean and dry, it’s time to reassemble them. Apply a small amount of fork oil to the foam rings and reinstall them, making sure they sit flush against the bottom of the fork lowers. Carefully slide the lowers back up the fork stanchions, aligning the bolt holes, and tighten the allen bolts securely.
Once the fork lowers are back in place, give the fork a few compressions to evenly distribute the fork oil and ensure proper function. Finally, check for any oil or fluid leaks and wipe the fork stanchions clean with a rag or paper towel. Your fork lowers are now clean and ready for your next ride!

3. With the fork lowers removed, you can now clean them thoroughly. Begin by wiping off any dirt or debris using a clean cloth or soft brush.
4. Next, prepare a bucket or basin of warm soapy water. Dip a sponge or brush into the soapy water and gently scrub the inside of the fork lowers. Pay attention to hard-to-reach areas and remove any built-up grime.
5. Rinse the fork lowers with clean water to remove any remaining soap residue. Ensure that all parts are thoroughly rinsed and free from any cleaning solution.
6. Once cleaned, carefully dry the fork lowers using a clean towel or air compressor. It’s important to remove any excess moisture to prevent rust or damage.
7. Before reattaching the fork lowers to your bike, inspect them for any signs of wear or damage. Check for any loose or missing parts and ensure that everything is in proper working condition.
8. Finally, reattach the fork lowers to your bike frame using the bolts you initially loosened. Tighten the bolts securely but be careful not to overtighten them, as this could cause damage.
By following these steps, you can effectively remove and clean the fork lowers of your bike, ensuring optimal performance and longevity.
Reassembling the Fork Lowers
Once you have thoroughly cleaned the inside of the fork lowers, it is time to reassemble them. Here’s a step-by-step guide:
1. Start by applying a thin layer of suspension grease on the inside of the fork lowers. This will help lubricate the moving parts and prevent friction.
2. Insert the dust seal into the lower leg of the fork. Make sure it is properly seated and aligned.
3. Install the new foam rings and oil seals onto the upper tubes of the fork. Use a fork seal driver or a suitable tool to press them into place.
4. Carefully slide the upper tubes into the lower legs, making sure the seals and dust seals do not get damaged or distorted during the process.
5. Align the fork legs so that the dropouts are parallel and facing the same direction. This will ensure proper wheel alignment.
6. Tighten the bolts or pinch bolts on the lower fork legs as per the manufacturer’s specifications. Use a torque wrench to apply the correct amount of torque.
7. Finally, cycle the fork a few times to check for smooth operation and to ensure that the seals are properly seated.
By following these steps, you should be able to reassemble the fork lowers correctly and ensure optimal performance of your suspension fork.
