GMBN's Essential Mountain Bike Maintenance Tips



keeping your bike running in top condition can be really satisfying so these are our essential maintenance tips and when student so something I'll do after every ride well first thing I'll do is clean it mine's nice and clean and we don't look too closely and once it's clean give that chain and a nice dry run it through a rag throw a little while get the worse the water off there and then what I'll do is put some wd-40 or gta5 something like that really light oil through it and again run the chain through the rag and get it as dry as you possibly can then it's time for our first essential maintenance tip is to lube your chain depending on where you ride in the season of the year try and choose the lube that will best suit that I've got some ceramic wet chain lube on because it's horrible conditions the UK at the moment so I'll use a nice thick Lube on there I always leave it down here by the jockey wheel the lower jockey wheel of the rear Mack and just drop it in from the top that way the oil will sit in here now work its way into the chain if you're using a spray Lube is very careful like getting it on your rear disc brake but I'm choosing this thick liquid and just drop it in the top of the chain to be honest I like to go really carefully with that don't put too much on but lows that on your chain will get all black as all the dirt and the muck sticks to it and that's like grinding paste on you can set and that can wear it out quicker so I like to go quite light on it and not use much leave at all so if I run the chain through my fingers you see you get a minimal amount of nice clean Lube on my finger and the chain is nice and shiny so it's clean and it's minimally lubed that is raised roll something else I check after every ride is my brakes more specifically I'll check that the brake pads are plenty of material left on them it's good to keep an eye on that so you can just order the pads you know so they don't have to miss any ride in times you plan exactly what you need to change them I'll also spin the wheel and make sure my disc is running centrally through the pads and it's running nice and straight make sure I haven't backed that disc and damaged it if your brakes have squealed when your right ride in then can check out of it our video on how to fix that a link that will be in the description down below contamination could do that there's a few other things so check that video I fix that problem another essential tip is to bleed your hydraulic brakes it depends on the make of those brakes to how regularly you'll need to do those some are more fuzzy than others any bleeding a bit more regularly to start to feel a bit rubbish but I'd say a couple of times a year is probably about right they'll also need bleeding if the lever doesn't feel consistent if it pulls in a lot and next time it doesn't pull in very much that's a sign that some air in there to get that air out of there but also some fresh fluid in there once or twice a year we'll make the brake feel nice in you something I'll keep an eye on when I'm riding it's a condition of my gear cables it's something that you'll start to feel through your thumbs when you're shifting if it starts to feel like there's a lot of friction in that shifter and it's probably time to change your cables also a sure sign of that is your gear changes start to get sluggish it might take a little bit of time to go up or down the block so that's not a very nice feeling time to change those gear cables it's hard to put a number on it I'd say probably somewhere between 20 and 40 rides I'll do that getting those gear change is nice and crisp and fast will make a big difference how your bike feels in the mid term other consumables our check would be tires and grips you probably weigh tires out quicker than your grips of things so keep an eye on those a worn out tire will puncture easier and obviously it when it grip quite as well so change those when needed in summertime I don't mind running a slightly warm tire on the rear because it'll roll quite quickly in the winter I'll make sure I've got pretty fresh rubber on there the whole time bearings they're all over the place so check those regularly headset just feel for any roughness or any vibration in there from wheel you can just hold your fork leg and spin the wheel spins nice and free freely and there's no roughness in there at all pedals give them a spin they shouldn't spin wildly and make horrible noise spin nice and freely bottom bracket rear wheel of seed just things to keep an eye on also bushes in your shock if you have full suspension bike our last essential maintenance tip is to check and replace your drivetrain match done a video on checking and replacing your chain already so check that one a link will be in the description down below but something at GM VM talked about in those videos quite a bit is replacing your chain for it's too ornate therefore you can save a bit of money on how to replace your cassette and your chaining at the same time but eventually you will have to do that to check the condition of your chain ring just have a quick look at it and make sure they're nice and uniform the teeth on there and they're not like shark fins or really low and warm and to actually replace your chain ring it's normally easier to take your cranks off the bike so check your manufacturer's instructions for that and then it's simply just to remove these four or five bolts depend on the make of your cranks the chain room will come off and replace it with your new one so there you go there are some essential tips to keep your boat ride and sweet and keep you out on the trail if you want to see more maintenance videos you can click up there for how to check your

    I need help if you would, I bought an Upland Aggressor mountain bike from the local Goodwill. Now I've never really done to much to any bike maintenance apart from changing a tire and this thing has been loyal to the best of it's ability but I've failed it ! The chain is skipping something fierce, the biggest problem, only the back brake works and both gear shift are pretty much shot. And all I'm wanting is something to get me to work and back could you please advise? I would be so very thankful to you, thank you.

    To prevent screwing something up, I just take my bike to the shop once every 1-2 months to get it serviced. Should I be doing maintenance on my own when it's not in the shop? I do lube my chain regularly, but is that not enough care?

    My back wheel has some sort of vibrations/rubbing feeling when I flip it upside down and spin it. It's a 2 month old hardtail but I ride really aggressive both on street and on trail. I know for sure that it doesn't make contact with the brakes nor any other part of the bike. Could it be the bearings or anything worse? Any reply is appreciated

    I have this bike and the pivot points at the bottom bracket are a pain to get out, I could only loosen them but not remove completely. I did follow your video of the e thirteen chain guide to strip it down and take the crank out so cheers. A video of maintenance on the GT i-drive system would be amazing. Cheers

    When I shift my rear gear to the smallest cogs, it sometimes misses or skips one. And when I shift my front gears, it's hard to press the bottom one on the shifters.

    Do I need to replace my cables or can I just put on some more lube, because I've already tried lubing the cables

    Can you make a video about what kinds of lube are good to use on your fork and shock? I wanted to get Fork Juice but unfortunately they don't ship it to where I live. Also a while back Marc said (in a Dirt Shed Show video) there is going to be a video about Schwalbe's ProCore, but that never came out. 🙂 Great video as always. Thanks.

    The rear derailleur is also a part that needs to be checked once in a while (and also cable tension). Poor shifting is the worst thing during the rides…

    You are talking about same things whole the time. You have never compare used chainring to new one. You are not telling us when we actually should change chainring. If you don't have new topic I can give you some Ideas.
    – How to change headset.
    – How to choose new rims.
    – A couple words about spokes.
    – Different chains on a different groupset ( comparison of durability ). Is it worth to buy chain from higher groupset?

    I would also add this, I think it's very important:
    Check if your wheels are true. True and straight wheels = strong, long lasting wheels, and if you notice that your wheels start to wobble, fix that before its too late.

    Hi. My disc brakes are rubbing and its really annoying. I tried to loosen bolts which hold the brake and adjusting it for the rotor to be right in between the pads. And it continued. It seems like the piston on one side is pushing more – is more sticked out, than the one on other side. Any help please? 🙂

    Don't put WD40 on a chain ever. Just use soap to clean it, then dry it thoroughly and apply chain oil.

    Also, after applying chain oil you should turn the pedals back for a while and then wipe off all the excess. Any oil on the surface will only make your chain dirtier.

    The way I clean my chain: using park tool chain cleaning device, poor some engine cleaner/degreaser and spin it for a minute. Then do same with moc-off cleaning solution. Bounce bike few times to shake excess off. Wipe chain with dry rag. Apply wd-40 to chain and spin few times. Wipe it dry and put bike away to dry. Apply wet/dry chain lube before ride.
