Servicing your mountain bike suspension can sometimes get pushed under the rug. For those who don't want to spend the money sending their fork back into the manufacturer to get serviced, or don't have the knowledge to do it at home, we are here to remind you the importance of servicing your suspension and walk you through the process. Just like changing the oil in your car, changing the oil in your mountain bike suspension needs to be on your to-do list certainly at least once a year. Over time, the oil in your suspension breaks down and gets contaminated with dirt and grime. With a quick service, your fork will feel like new again!
In this installment of our mountain bike How To series, we are going to be doing a lower leg fork suspension service on a 2020 Fox 36 Factory Series fork. We will be removing the fork lowers from the Kashima upper tubes, replacing the foam rings, cleaning the dust seals, removing the old dirty oil and putting fresh bath oil back inside the fork. We won't be tearing into the damper or the spring side of the fork, rather just giving the fork a quick freshen up. This service can play a major role in the overall performance of your fork out on the trail. Follow along and don't be afraid to dig into your own fork! This same step by step process can be followed for all Fox forks. Just be sure to reference the oil bath volume chart to find your fork.
Before we get started, remove the fork from your bike and make sure it is nice and clean. Also, make sure you have a clean work environment that way no dirt or grime can get into your nice fork. The easiest way to service your fork is to hold the fork by either the steerer tube or the lower leg in a bike stand. Now let's get to it!
