Basic MTB Fork Maintenance You Should Be Doing | Mountain Bike Maintenance


– [Doddy] Mountain bike
suspension is something we’ve all come to rely on as such an essential part of
mountain biking these days. And while it’s really reliable and works very well once set up correctly, it’s all about the maintenance to ensure it stays working that way. So here’s some top maintenance mistakes that some of you make,
and how to avoid that. (swooping beat) Now watch the suspension
forks like the forks that you see here. It’s gonna continue working
whatever the conditions. It is all about the maintenance. And to make this fork work
well, it’s A, gotta be clean, and B, it’s gotta be well-lubricated. So on the lowers of the
fork, I have 10 ccs of oil. That oil is purely to lubricate the bushes and the seals on the inside. So soon as the forks start drying up, you’re gonna get other damage occurring. The seals themselves,
they’re gonna dry out, and you’re gonna start getting scoring on your stanchion tubes. So if you do get scratches
on your stanchion tubes like this fork here,
that’s really expensive. Because although you can
get an individual stanchion pressed into the crown,
really when you get these on warranty replacement or
you have to buy a new one. It’s the whole unit,
and that’s about a 1/3 of the price of an entire brand-new fork. So, make sure you look after your seams. Keep them lubricated and keep them clean. So the foam rings and the wiper seals are actually fairly cheap to replace. You can do this yourself at home when you perform a fork lower leg service. There’s not too much of a
problem if your bushes wear out. Not only is that a problem
for your stanchion tubes and the scoring on those,
these are quite hard to replace and you’ll need to get these done at a suspension centre like Mojo. Which is where we’re at now. What you want to look for, as
well as the dryness of these to replace is you’re
looking for a knocking in the upper leg and the lower leg. So, there’s always
gonna be a minute amount of movement otherwise, the
legs simply wouldn’t slide over the top of this. But as soon as you get excessive movement, then you definitely want
to get these replaced. And put your fork in for service. Don’t continue to ride them like this. You’ve got to look after these things. They’re expensive. Let’s chat to Chris Porter. He is a shock wizard, and
he’s gonna tell you everything he advises you to do. Give me three tips on
looking after your fork. – All forks out there
are easy to look after. And the first thing you
should do is look online, find videos of how to do
seal and lowers maintenance. All of them will allow you
to drop the lowers off, clean and grease the seals,
and re-lubricate the lowers. It’s normally a 10 minute job. It’s a 1/2 an hour if
you’ve never done it before. And it’s really simple to do. – Okay. That was one, so, give me another one. – Well, I mean, we don’t get
dry summers often in Britain, and but we do. And like you see, Neil’s been out and he’s got quite a lot of dust here. I’ve still got shorts with pockets and I always carry a
little rag and I’ll just every now and again, just
give ’em a little go. If I’m about to hit a descent or I’ve paddle up to the top
we’ll be sat chatting. Just give ’em a little wipe. Because all that dust absorbs
all the lubrication that you’ve put there from the fork action that’s on the stanchion. It absorbs all that lubrication and makes everything dry. And it’s the same effect as
putting cement on an oil slick. And so if you can just keep them clean and it’s half the battle. – Perfect. Okay. What about the bushes on the inside, sometimes you get that knocking. How long do they last and do you, – If the bushes are knocking, normally that suggests that they’re dry. Most of the bushes run, you know a .1, .2 of the mill clearance, and if that’s coated in oil and then the film strength is enough that you won’t feel any movement. If you can feel knocking,
it’s already dry. It’s time to do something. – It’s time for new bushes. – Well, you might get away with it, but if you’ve run them
dry, then they’ll polish. You know, you just gotta,
you know accept that, Oh, I had to do another week’s
ride in there in Morzine and they were already dry. You know you’re gonna need
to spend some money probably. (laughing) – Okay, so there’s a whole
bunch of reasons there to look after your suspension. To get it set up right in the first place. So hopefully you enjoyed the video. Don’t forget to subscribe by clicking on the globe right here. – And you can find a link
