Suspension is like a marriage: when it works, it’s brilliant; when it doesn’t, it’s horrible; and if you ignore it, it can become very expensive.
The good news, however, is that there's only one thing you need to do to keep your suspension happy: maintenance. And it's easier than you think.
Whether you've got forks, a shock or a dropper post, these things should tip you off:
Let us show you why that's a bad idea.
This fork oil is a lot darker than it should be. The culprit is contaminants.
When oil is full of contaminants, it's far more abrasive. Abrasive oil accelerates wear. It’s not only contaminated by the old seals and glide rings breaking down, but as the external seals wear, they let grit, dust and debris past into the body of the suspension. Once they're in there, they basically act like sandpaper on your fork stanchions or damper body, and do things like this:
In addition to the abrasive action, you’ll also notice that the suspension doesn’t perform as well. Fresh oil is nice and slippery while contaminated oil is not.
It's pretty hard to have a great time out on the trails if you have to keep pumping your shock up, or if your forks bottom out on every jump, or if your dropper post just acts like a pogo stick.
In addition, ignoring suspension issues not only affects your ride, but can also end up costing you a lot of money. Small issues (like leaking seals) can be fixed with a service, but if you keep riding suspension that's suffering, sometimes the problems become too big for even us to fix. That's when you end up needing to replace the forks, shock or post completely. Considering that even the most basic shocks and forks start at around $500 (and go up to several thousand dollars), regular maintenance can save you major cash.
Service work can also pick up problems before they turn into catastrophic failures.
Here’s another fun suspension-related word: cavitated. Cavitated oil basically means that it’s full of air.
There are two give-aways:
The simplest home maintenance tip is to keep your suspension clean. Don't blast it with a hose, though -- all it needs is a gentle wipe-over, particularly after dusty, muddy or wet rides. This will help keep some of the grime and grit from working its way inside the seals.
You can also add a drop of stanchion lube to the seals to keep them supple. (Note: there's no need to start pulling seals out or trying to get the lube past them; the lube will work its way in as you ride.)

It's incredible! From the moment I took it off the bike rack, and put it on the ground, it made zero vibration sounds. Just the sound of raw tyre to brick knock, and a gentle chain clank to the derailleur cage. Gone were the standing-vibrations that rattled throughout the entire bike. I'm…Tom Bammann
