Do You Really Need To Maintain Your Mountain Bike? | GMBN Tech Investigates...

[@cjansson]

One thing that I found is that overpacking frame bearings with good quality grease and then only rinse the bike off with a high pressure nozzle on the garden hose works great. I do use a chain cleaner with a degreaser when required, but that's it. So far, 6 months in there are no creaks, no play and chain is still holding up. Previously using a cleaning agent everytime after a ride wears away the grease at an alarming rate and creaking sounds appeared after a couple of washes. Sure the bike does not look clean but it is where it counts.

[@James-dn1hu]

Suppose this depends on riding conditions. If your riding in thick mud all the time then having more grease around the bearings can be bad as it attracts more dirt to them causing more grinding.

[@cjansson]

@@James-dn1hu sure but it seems to work for my grease and frame. Mud is no issue, the little that gets stuck in the outer layer of the grease gets rinsed away with water when washed. If you have no grease it will work its way in the bearing directly, unless you are diligent and take it apart to clean and repack with grease. At least that's been my experience with my pole evolink and previous my older stumpjumper. Its like the solvents in the detergents make their way through the seals faster than mud via some extra grease.

[@alphaomega5721]

Yup. Degreaser and high pressure are no-nos. I only wash my bike if it's got lots of mud. Otherwise it stays dirty until a complete strip down and complete rebuild. Takes a day and each component is checked. Haven't replaced components in a long time.

Contaminated brake pads are easily recovered by cooking them. A propane torch is good, but put under the griller in your kitchen works too - cook them until they stop smoking ;)

You can always recover contaminated a rotor. Pads are usually a goner. The outward bend of the cage on shimano derailleurs is a feature!

[@patoberli]

True, but at 20-30$ for a typical rotor, question is if it's really worth the effort. Also the cleaning stuff also costs at least a tiny amount.

those shimano 12 speed derailleurs come with what looks like a slightly bent cage, put a new xtr on a new build and thought it was bent but did some research before trying to bend it back

dont really do regular, scheduled maintenance on my bike. Just listen for funny noises and give it the odd squeeze here, a twist there, and a couple drops while chatting with friends. Tho I did just have my rear hub come loose on my last ride. granted, i did hear it for a while, just couldnt pin point the noise. thought it was the spring in the rear brake

[@megatfaizarif690]

Nice initial diagnosis on Jack's bike

[@Jcee4]

Every manufacturer and rider says their chain lube is the best. Each one receives negative reviews too, often referring to dirt and muck it collects either on the chain itself or around the pulleys/derailleur chain guide, particularly regarding wet chain lubes (I'm in the UK). Is this mainly because of infrequent maintenance or cleaning, or do any particular wet lubes stand out which don't compromise efficiency? Pre-prep is not an issue for me, but it would nice to find out which the better one is for either quick clean or pre-prep conditions in each case. Squirt seems to have most positive feedback % thus so far when I read rider feedback.

#AskGMBNTech can you mix different tire sealants? My Giatn came with some Giant tubeless sealant and I have Stan's No Tubes sealant. Can I use it to top it up, or I have to clean previous sealant, washout rims and then add Stan's? Got my bike for like 2 months, had no issue with sealant, but planning to do my first XC race soon, so thinking to top up just to be sure

[@downinla4076]

I wouldn’t mix different brands. I mixed Stan’s with Orange, not knowing any better, which turned my sealant into cobwebs. I had to throw the tire away.

#askgmbntech Hi there, recently I installed a megneg air can onto a rockshox deluxe select plus. Once on I found that the shock now leaks air. I can’t can’t find a visible leak and I checked everything and it looked ok. I took it apart and put it back together again, it still leaks but slightly less. What do you think the problem is? And how can I fix it? Thanks a lot

[@Kovacs-sf1hi]

It’s probably happening when sliding the new air can on. it can be difficult because of the resistance and that is more than likely causing one or more of your seals to move out of place, causing a leak.

[@Windband1]

Are you putting a thin layer of grease around the o-rings first?

[@benfairbrother2458]

Thanks guys I took apart the shock put more grease on all the seals, put it back together carefully and now it works like a dream

I am not sure if it is ok to maintain my bike by myself or ask my dad to do it for me.

[@ThunderStruckMTB]

With the internet, and especially KZbin, there is no excuse not to work on your own bike. Two labor charges for a shop to do a lower leg service on your fork will pay for most of the tools that you will need. The rest is just trying.... Any bike of mine has not seen the inside of a LBS in 30 plus years and the saved labor costs have probably paid for my current bike.

[@silys5253]

Stop saying that people should not touch the rotors. Its tough to manage and does not guarantee there will be no oil or grease on it. Best practice is to clean the rotor right after install - with a clean paper towel and lots of brake cleaner -> same stuff you use to degrease your cars rotors after install. In fact - I have driven through oily puddles and stuff (car must have lost oil on road) and I have recovered my brakes by cleaning rotors and pads.

[@Guido-vj7so]

Happy mechanics at the store, I'd say it's much too often. There are some minor things you might wanna do yourself every 500km, but to take it to the shop so often, seems a bit overkill. But it's your money and they might be worth less than your time.

[@dax2110]

A new rotor because you got some spray lube on it? Why not just clean it... And the pads can be cleaned too / sanded or just run the contaminated rotors and burn off the oil.

I'm an older rider starting back after a 10 year break. This bike exceeds my capabilities and has been easy to get comfortable riding. I'm mostly on easy trails with almost no street riding and have not been disappointed with the performance of the bike. My fitness level is far below what I previously rode with and because of that the mileage is going on the bike slowly. While I'm losing weight slowly, the bike seems to tolerate my 220 pounds just fine. The bike has been used by several family members ranging from 5'5" - 5'9".
