Fox 40 Travel: Understanding the Basics

The Fox 40 is one of the most popular downhill forks on the market, known for its robustness and performance. One of the key features of the Fox 40 is its ability to adjust the travel, allowing riders to fine-tune their suspension for various riding conditions. Changing the travel can greatly affect the fork's handling characteristics, so it's important to understand the basics of how to change the Fox 40 travel.

Before we dive into the process, it's crucial to note that changing the travel on the Fox 40 requires some technical knowledge and the right tools. If you're not confident in your ability to perform this procedure, it's best to take your fork to a qualified bike shop for assistance.

Here are the steps to change the travel on a Fox 40:

Step 1: Preparing the Fork

First, ensure that you have all the necessary tools. You will need a set of Allen keys, a torque wrench, a Fox 40-specific top cap socket, and a 24mm socket. Additionally, make sure you have a clean workspace and a mounting stand or bike repair stand to secure the fork.

Step 2: Removing the Fork from the Bike

If the fork is still mounted on your bike, you'll need to remove it before you can change the travel. This can typically be done by loosening the axle pinch bolts on the lower legs and removing the front wheel. Next, remove the brake caliper from the fork by loosening the mounting bolts. Finally, remove the stem cap and loosen the headset bolts to release the fork from the frame.

Step 3: Draining the Oil

To change the travel, you'll need to drain the oil from the lower legs. Flip the fork upside down and remove the lower leg screws using a 5mm Allen key. Be careful as the oil may drip out once the screws are removed. To speed up the process, you can push the fork down to force the oil out.

Step 4: Changing the Travel Spacer

With the oil drained, you'll now have access to the travel spacer. The travel spacer is a small plastic or metal piece that determines the fork's travel. Depending on the model and year of your Fox 40, the travel spacer may be located on the air spring rod or inside the air chamber. Check the Fox website or consult the user manual for specific instructions on locating and changing the travel spacer for your fork.

Using the appropriate tool, carefully remove the travel spacer. In most cases, you'll need a 24mm socket to unscrew the air spring rod and access the travel spacer. If the travel spacer is inside the air chamber, you may need a Fox 40-specific top cap socket to remove the top cap and access the spacer.

Step 5: Adjusting the Travel

Once you have removed the travel spacer, it's time to determine the desired travel and install the appropriate spacer. Fox 40 forks usually come with multiple travel spacer options, allowing you to adjust the travel within a specific range. Refer to the Fox website or user manual to find the recommended travel settings for your specific fork.

Install the new travel spacer and ensure it is securely in place. If you're using a metal travel spacer, make sure it is aligned correctly and tightened to the manufacturer's specifications. For plastic spacers, check for any signs of wear or damage and replace if necessary.

Step 6: Refilling the Oil

With the new travel spacer installed, it's time to refill the lower legs with fresh suspension oil. Use the appropriate suspension oil for your fork model and refer to the user manual for the recommended oil volume and weight. Slowly pour the oil into the lower leg, taking care not to overfill. Once filled, gently cycle the fork up and down to remove any air bubbles and ensure proper oil distribution.

Step 7: Reassembling the Fork

Now that the travel has been adjusted, it's time to reassemble the fork. Begin by reinstalling the lower leg screws, ensuring they are tightened to the manufacturer's specifications. Next, reinstall the fork onto the bike frame, tightening the headset and stem bolts securely. Finally, reinstall the front wheel and brake caliper, torquing the mounting bolts to the manufacturer's specifications.

Step 8: Testing and Fine-Tuning

Once the fork is reassembled, it's important to test the suspension and fine-tune the settings. Inflate the air spring to the recommended pressure and adjust the rebound and compression settings to your preference. Take the bike out for a test ride to gauge the comfort and performance of the new travel setting. If needed, make further adjustments to achieve optimal suspension performance for your riding style and terrain.

Changing the travel on a Fox 40 can significantly influence the fork's characteristics, allowing you to optimize your bike's setup for different riding conditions. By following these steps and exercising caution, you can safely and effectively change the travel on your Fox 40 and enjoy a more tailored suspension experience.
