I friggin' love Christina; especially love the way she kick's Tom's ass at every contest they do:) Great video and i do believe that you're correct in that most people even forget they have bearings never mind check them.
@1:39 you mention to stick your finger in but not what to feel for besides being seized. It should spin freely and smoothly. If it feels gritty consider replacing.
I have fuel ex 8 2020, and I was recently change bearings on rocker link, and on seatstay with RRP extraction tool. Funny thing is that I couldnt find in my country seatstay bearing 10x19x8, but I order them from UK. Bearings which are inside Trek frame and on chainstay I just open ( remove plastic cover) clean and put grease inside. On some MTB brands, bearings are very bad greased (low amount of grease) from factory so I suggest when you buy new bike check bearings. I do bearings maintenace 1-2 times a year.
I generally find machine shop/ engineering places are better for finding odd bearing sizes . Rs before the bearing code stands for rubber seal . It's handy owning a vernier or caliper also to measure what you need . Inner and outer diameter /width
If you are in the UK I would try Kinetic bike bearings as they do loads of bearing kits. They also stock just about every bike bearing you will ever need for your bike. Quick postage too. I’m a professional cycle mechanic and use them loads.
Funny timing on this video. My upper linkage bearings were just making a terrible creaking sound. Purchased new ones from the manufacturer and took the link up to my LBS to push the new ones in. Back to being silent and feels good. Replaced the entire bottom link, which came with fresh bearings. All that said, I got over 3k miles on the original bearings before they started making noise.
My carbon frame has aluminum slots for frame bearing to slide into and i wish i had started servicing my own bike sooner because a couple of bearings got ceased into the bearing spot and now im stuck with these bearings forever I work at a shop too we along with other shops were unable to remove the bearing
maybe not using force, but preparing it with something like WD-40 such extreme penetrating surfaces and spaces, therefore You can try move this bearing, or repeat with some more WD-40 and try again
I always remove the black plastic bearing covers and clean and repack the bearings. Makes the bearings last for a long time before replacement is needed, and very easy to do as well.
@@steve4296 absolutely, but the majority will be too far gone by the time they are checked for the average rider. If I’m going to the trouble of taking the frame apart then I will just put new bearings in each time.
@@Adam-vm8kp This should be done 2-3 times per year making it part of your regular maintenance. I find it pretty easy to expose the bearings to service them, but most are too busy or just can’t be bothered. If that’s the case, then just let your shop maintain your bike.
My bikes rear wheel is loose and it wobbles around. I’m 100% certain that this is not caused by my rear hub, because I checked it several times. I am certain that it is caused by my rear triangle. I did check all the bolts and retightened them but it problem is still there. Could that be cause by worn out bearings?
Remove the wheel, the hub will have play at the axle or the frame will have play. But yes worn bearings develop play and can cause the wobble you describe, especially if the frame has bearings near the rear axle.
If I’m thinking the same exact spot - the instructions I read when changing out my rear derailleur hanger said specifically not to grease that spot. I thought it odd too but engineers who designed it probably know best 🤷♂️
Depends really. I did a service last night actually and the bolts with loctite on them already, I do NOT grease because it defeats the purpose of the loctite. Everything else, I pretty much do -Christina
You can put a slither (and I mean a slither) of anti-seize/grease behind the bolt head and on the smooth shaft of the bolt, but DON'T put any on the threads! Threads should be clean and dry with a dab/smear of threadlocker on them.
Does anyone know what the difference is between a Scott Spark 100 and 120mm swingarm repair kit before I find out the long way? (previous gen model). I have 100mm/RC but only 120mm rebuild kits were available.
Press fit linkage bearings in carbon frame is a bad design practice. It is the most common source of “cracky/noisy” bike. Bearings should be press fitted in aluminium material (linkage or frame).

when my hardtail pivots, i replace it.
LOL 😆

And no mention of how to remove bearings. Cool video.

@@pinkbike you are welcome.
Happy ride! 😎🤙
HAHAHA!! So fun. Entertaining. Have been wrenching on bikes, race cars and all kinds of stuff since the late 70's. Good stuff.

I bought a bearing extractor from Bearing Pro Tools. Just in case there are any DIYers reading down here.
Cool videos, keep them coming with Christina!

This is the follow-up video needed on this channel (not that I can't find it elsewhere).
Once the races or balls are pitted or rough it’s a waste of time trying to clean and re grease. Bearings are cheap.
Cleaning and repacking with grease is obviously done to bearings in perfect condition. This is a preventative measure only.

Shouldn’t you put grease between the bearings and the bolt or bearing cover? 😅

Thanks, Christina for a very helpful instructional video.
People over thing it great way to check them and re grease hardware they are either good or not
Ok this is exactly why I spent 2k on a hardtail.
I swear I took my rear pivots out yesterday to check them and didn't see any bearings, just bolts. Or maybe I'm tripping. 🤔
Some use bushes instead
Ever heard of bushings?
I am Japanese. That sounds like fun too.
What's the outro music?
Smooth operator
How do you safely remove the bearing!? 🤷♂️
Bearing press tool.
Riding rockshox now instead of marzocchi now?
I remove the swingarm bearings and replace them with self lubricating bushes
Just make sure you don't do it alone. It might be difficult, because you only have two hands.

I already have a bike, but thank you.
The bike shop is trying to charge me 1000 $ for bearings and a new cassette and chainring
❤️
I need a MTB first.
That's why I ride my hardtail more, less maintenance!
Also you can tell everyone that you ride a hardtail which people who ride hardtails just love to do sooo much. 😝
@@HollyBoni Hey, at least he's not a singlespeeder.
How do I know this?
He'd have said so.
@@phrides Been there, done that. Definitely not my cup of tea 😂
