Bearing, bearings, bearings, Who thinks they know the score?

anyone want a Kelloggs nutrigrain morning bar?

Is it virtual?

This is bonkers.

For the record though.. Full compliment in frame and headset bearings, caged everywhere else.
Most headsets take 36×45 degree 1 1/8" ACB's which are available in stainless for about £2.50 from your local bearing factor. Just read them off the numbers from your current bearings and they'll supply.
You can get almost anything that's available on ebay for the same price locally. Strange that, isn't it?

"Chinese bearings"

Take 15 years to arrive, cost $13m and get extremely poor reception when they finally arrive. Also, in the meantime all of the bearings but one will have been replaced with other hired bearings.

What kind of frame do you run and what kind of caged bearings. To get at the bearings on a caged bearing the water / dirt needs to get through the cage. Plus enduro max a pregreased bearings, so you would expect them to last longer.

I'm betting you run a frame manufacturer that uses rubbish caged bearings. There is a world of difference between top end bearings and the rubbish that commencal, specialized, giant, etc all run.

SV I got banned from mtbrider.com for winding up SteveL aka BapMan. I think the exact comment was, Point taken I will leave your little kingdom as I found it bapman, in capable hands. That said if he's trying to wind me up I am most certainly winding him up! which is only fair.

I don't 'run' a frame, I ride/own/have a frame

How exactly can't mud/water get to the ball bearings because of the presence of a cage? The cage surely seperates the ball bearings, not seal them?

When the cage collapses, the ball bearings end up on one side of the bearing though, something that happens all of a sudden, often mid-ride. At least a full complement will hold itself together when worn, it may have noticable play due to worn ball bearings/races but it'll take more hammer before it fails like a 'caged' will?
IME, the (worn) full complements seize up, with the (worn) 'caged' type, the cage collapses

Not my fooking rules so I aint playing buy them, as for being an annoying **** to other users. That's the whole point Bapman, your minions wound me up so I wound you up, Savve!!!

Wrong a cheapo bearing of the caged variety will fail sooner not a pregreased performance bearing. The cage surrounds the bearing hence the term cage. dirt and water will therefore find it harder to get at the bearings.

What manufacturer of frame do you have?

Kaesae,

Just for the record, that is me in SFB's pic on the third post. That bike has been ridden through rivers of shite every week for four years and the original bearings are doing just fine 😀

well, I bought a shitload of nutrigrain bars, they are the real deal, from tescos at a bargain price. they are the real shit no doubt, 8 for £3.00 posted. Or I will eat them myself (virtually) and save you postage for £2.00. cheers!

ps. Multiples of 8 only. I bought a shitload.

With KP5A aircraft grade bearings made specifically for high and low altitudes, very hot and cold weather and extreme conditions.

I wonder why?

"The cage surrounds the bearing hence the term cage. dirt and water will therefore find it harder to get at the bearings."

I start to wonder if you've ever seen a cage bearing.

It must be difficult "testing" all these bearings when you can't ride…

I start to wonder if you've ever seen a cage bearing.

I start to wonder about the guys sanity!

Kaesae – You either were winding SteveB up or AndyL not SteveL, either way Steve runs a very successful shop (you know a business) and Andy had you nailed on technical questions you never answered and indeed avoided answering.

Got any bearings for an Ifor williams?

Is that a high or low altitude Ifor Williams??

sv only in the mind of a fool could the questions not have been answered. As I said and continue to say.

1) There is a perfomrance gain to be had from performance top end bearings, it's the reason a lot of race teams run them Stendec who do the race tuning for the Intense race team and also Giant and Specialized's race mechanic. All who I have spoken to at length during my research and who have confirmed the fact. If you wish confirmation call them yourself and simply ask. It is also the reason that good quality performance bearings are used by the car industry as the maintenance time offsets any benefit from saving money using cheapo rubbish.

2) It is possible to improve the performance on MTB frames over and above the standard factory spec, That having a rear end action that is stiff but smooth in it's action without any flex is a good thing. Just like running a through axle on your wheels will eliminate flex so running performance bearings will do the same thing, The action will be stiff but smooth.

3) Caged bearings have a good portion of the bearings surface covered by the actual cage and will more likely than not have grease trapped between the cage and bearing surface. I would think just as anyone who has an IQ above that of the average donkey, that this fact will make it harder for the dirt to sit up against the bearing and sieze it, with the cage in the way of the dirt.

4) This isn't actually aimed at you to be honest as I believe that no matter what answers I give you will be man enough to admit when your wrong, or smart enough to know you are. There will be some who have the intellect to understand.

northwind you start to wonder if someone who sells caged bearings for part of their income has ever actually seen a caged bearing? Genius.

Kaesae please stop this nonsense. Your claims are exactly that, claims. And they are wrong. You need to think about what you are writing and take a step back.

Shame you felt the need to get personal kaesae – but it's obviously a good way of diverting attention from my (unanswered) point.

I've not stated anything that relies on my experience of bearings and IDGAS what you think of me. If you put yourself forward as someone who knows everything about bearings with stuff like this:

that this fact will make it harder for the dirt to sit up against the bearing and sieze it, with the cage in the way of the dirt.

Then in my eyes you have no credibility whatosever.

This sort of reminds me of the bi-polar messianic rantings of a schizophrenic cult leader.

"3) Caged bearings have a good portion of the bearings surface covered by the actual cage and will more likely than not have grease trapped between the cage and bearing surface. I would think just as anyone who has an IQ above that of the average donkey, that this fact will make it harder for the dirt to sit up against the bearing and sieze it, with the cage in the way of the dirt."

Stopped talking about the cage keeping water out? Good show, you're halway through a succesful climbdown, that's a useful skill to learn, keep going.

This is turning into a very amusing thread. Please continue feeding the troll…

: P

I'm just annoyed nobody seemed to get my Guns N Roses joke, it probably just looks like I was babbling like a mental person.

ah, the Chinese bearings one – I get it! Sorry for being so slow. And yes, I did think you were babbling like a mental person. 😉 Mind you, on this thread you wouldn't be the first…

Photo of a caged bearing, the surface of the actual balls is covered to a large extent by the cage and of course the races. For water or dirt to get at the balls it has to get past or through the cage.

Water will cause rust yes but seizing of bearings is far more likely to occur due to dirt sitting up against the actual bearings which of course full compliment bearings are far more susceptible to than caged.

You say insulting I say pointing out the obvious character flaws of STW members.

Here is my point I will make it clear and as accurate as possible.
What I do to these frames and the performance benefits my kits give a bike have been testified to by the riders that use them.

Not only local riders who have had their frames serviced but also riders that buy them through ebay.

If my theory and idea works ladies and gets the job done, How can anyone in their right mind claim that I am wrong.

The riders that use the bikes confirm that what I claim is the case, they are the ones most suited to determine if I am wrong not you.

Get out of that, if you can!!!

what bearings would i need for a giant trance x and what cost?

Kaesae – so you say your customers say you are the best, therefore you are the best?

You should be in politics…

Still not answered my point.

So, just to get this straight, someone who sells caged bearings is trying to convince us, in purely anecdotal and not particularly verifiable terms, that having small fragments of metal in between the balls (though not completely surrounding the balls) somehow prevents the ingress of dirt and water, and not only that but having fewer balls to share the bearing load is in some way a good thing that increases the life of the bearing?

…

No thanks.

He is almost right, though for the wrong reasons. Caged bearings are a bit better at dealing with contamination than FC bearings. Not because the cages keep out dirt (they only locate the bearings, it's seals you need to keep out dirt) but because the cage and the space between the balls it creates gives the dirt somewhere to sit. In a FC bearing the dirt is more likely to eat away at the bearings/races.

You need to remember though kaesae, there are primarily two types of people on here, engineers and IT folk. This leaves you with two things to consider:

1) Engineers know more about bearings than you do

2) Everyone else (including the IT folk) may or may not know more about bearings than you. They do still know that you come across as a complete tool though, hence no-one really liking you very much.

Well said! And that's starting to make sense. But otherwise, cheap bearings are still cheap bearings, even if they've got more space around them for the cack to hide.

Is SteveL the mutant off spring of SteveB and myself?

did you mean…
?

So have we finished with bearings yet. How about talking about the merits of dustcaps , I prefer a finer quality dustcap not the crappy Taiwanese made or god forbid Chinese, no, much better to nick the German type ones as found on German BMW's with a built in air release mechanism……yadayadabroootdutduuutbryngdingding………..

when exactly did I say that cages keep out dirt or water?

kaesae i respect your tenacity, i havent read the rest of the thread tbh

i know nothing about bearings.

or bottom brackets for that matter.

i need to replace my bb i run a raceface evolve xc crankset (2008/9 ish) with a self extracting allen bolt set up.

some questions

1) what type of bb do i need? is it mega exo or something, is that a generic name or does each manufacturer havetheir own?

2) do you do external cups in the "hope red" colour?

3) which bearings would i need for high mileage low mud conditions, how much are they and how do i buy them?

cheers

Lets see this hokey cokey then

No SteveL is my pet name for Bapman do you want to hear yours?

There you go. Saved you looking too hard. FAIL.

Sorry can you elaborate I still don't see what on earth you are talking about. The question was when did I say the cages keep out dirt or water?
