Maintaining your suspension fork will have your bike performing at its best! If you are starting to feel like your Fox fork isn't riding buttery smooth like when it was new, chances are its time for a lower leg service. Fox recommends a lower leg service about every 50 hours of riding, and it's a relatively quick and easy way to freshen up your fork. In this MTB How To, we are going to be doing a lower leg suspension service on a Fox 49 fork with the Grip 2 Damper. In this service, we will pull the lowers off of the upper tubes, replace the foam rings, and add new bath oil. Before we get started, make sure your fork is nice and clean, that way we don't introduce any dirt or contaminants into the system.
Servicing most Fox forks follows a very similar process, so if you are looking to do a lower leg service on your Fox 36 for example, there is still some great info in here for you as well. If you are servicing a Fox 40 with a 27.5 chassis, follow the same exact process here. Let's get in to it.
