How freely do your Hope rear hubs spin?

[JXV]

Sitting back and enjoying my popcorn.....B)B)B)

 

I could understand the fuss if we were all replacing bearings on our bikes weekly and looking for a better way...but we're not.

 

Those who want to drown their bearing in grease.....cool, go for it.

 

1 bb, 1 front axle, 2 rear axles, several pivot bearings, a few eggbeater bearings and no headset replacements in 11 years of cycling with no repacking of bearings except the Shimano cones. My fit-and-forget philosophy works for me. I go riding with all the free time it gives me.

If you consider those things real rubber seals, those things that have a metal piece coated in rubber, the your layman's qualifications must be with a distinction.

Have fun, especially when the race starts pitting and the balls start losing their roundness.

Sorry for joining your topic where you asked for help only to dish out expert advice to yourself.

 

That's correct rubber seals, as used successfully literally in 100s of millions of bearings the world over everyday, tried and tested/industry proven for decades. At least you can say you've learnt something from this thread, so not all is lost. Keep an eye on those 4 Chris King headset bearings and don't forget to service them regularly.

No worries, you still have a lot to learn, I admire your passion , I have noticed how you partake in every technical thread possible of late, I just hope that the people who need help ,take advice with a pich of salt.

 

You win this battle, I concede that all bearing are there to be serviced, especially the ones with the rubber squeals .

Sky - 1 Layman - 0

Sorry for the intrusion .

 

A maths lesson will also help you, 4 headsets equals to 8 bearings .

Sorry OP, one last question ,how many bearings do you work on ,this will be on a daily basis ?

Wheels, headsets, bb's and pivot bearings.

well you clearly don't work on any.

you just chuck them in the bin and put new ones in.

 

unless they are CK of course

Good question, I'd throw that question right back at you and then ask how you can own an Lbs and have 4 Chris King headsets on your personal bikes and not know that the headset bearings need to be regularly serviced and regreased.

You live you learn, no doubt about that.

[kosmonooit]

Haha haha, Chris King is is just like any other CK handbag. It's all just rebranded.

 

I have cleaned and reused pretty much every type of bearing, Pivot, headset, BB.

If their is no play the bearing can be cleaned and reused.

I have taken a seized bb bearing back to prefect use with some parrifine and new grease.

 

If you Can waste cash on new bearings when you don't need then good for you

 

What you also have to check for is, are the contact surfaces pitted? One can inspect visually after cleaning but you will also feel it when rotating - it will feel rough as the balls (or rollers) ride 'em pits.

 

Free advice, take it, don't take it.

I do actually, Shimano hubs and older headsets and then there is always the one or two bikes that uses a cup an cone BB.

 

The rest are consumable, the way they have been designed to be.

Quite simple.

4 bikes and the milage per headset becomes considerably less.

Regular cleaning and maintenance such as removing the fork and cleaning the races also makes a massive difference.

"You live you learn"

Yip, that rope of yours is long enough.

Please Kosmo, don't even mention the pitting, I raised it an it was ignored.

Let's not even mention those soft plastic cages the balls sit in.

This has been fun, thanks y'all

 

Here's a bearing question: is there any realworld benefit to go ceramic at all, or just a marketing ploy?

If I may ask, what other hobbies do you have ?

[tombeej]

I don't get the question Wyatt, please elaborate.

[Wyatt Earp]

I don't get the question Wyatt, please elaborate.

 

If you have other hobbies then the extra cash you save on not getting ceramic bearings will come in very handy

But soon someone will be here to tell us how much longer they last, smoother and lighter they are and they will gain you 30 seconds per km.

Sorry if that sounds arrogant, it's .......wait for it IMHO

[tombeej]

Ah ha, got you now .

 

Marketing ploy it is then.

[GoLefty!!]

 

 

You've never serviced a sealed bearing in your life?!

 

Hope factory specified and aftermarket(enduro, bearing man etc) bearings come with 2RS/rubber seals and are easily serviceable, pop the seals off, clean and relube.

 

 

Sure it's simple to pop the seals off and regrease. Point is those seals are easily removable so if the application does not need them then the seals can be removed. Regressing of those industrial bearings is necessary because the high speed they run at eventually forces oil past the seal and a regrease is needed to replace the oil. At bicycle speeds those bearings never build up enough pressure to force the oil out and if there is oil coming past the seals it means the grease is finished and there's dirt in the bearing. Regreasing does not fix the worn bearing. Any dirt or recluse requirement means sealed bearings need to be replaced.

 

Maybe a lesson in how bearing lubrication works but I'm sure a googlelator will jump in to teach.

[Super_mil]

I don't believe anyone has stated that regreasing a worn or pitted bearing is going to 'fix' the bearing or extend its life. It would need to be replaced. I think we ALL agree on this.

 

I think the point people are trying to make is that a bearing that is still good (i.e. not worn and not pitted), but has the old grease (which will have some dirt in it) cleaned out and replaced with clean grease will last longer than if the cleaning/regreasing exercise was not carried out.

Yes you are quite correct. Clean grease is better than dirty grease if the bearing is still good.

 

But the real point that some of us have been arguing - till blue in the face - is that it is not worthwhile. Think about it:

1) regreased good bearing still won't last as long as a new one

2) time required to remove, strip, clean, regrease, re-assemble and refit is more than just replacing with a fresh bearing

3) more waste to be disposed of - waste solvents, old grease and rags/paper towel

4) more regular removal and refitting of bearings will increase wear and tear on the interference fit of the bearing sockets in your expensive hub / frame components.

 

Neither camp is right or wrong, you can choose either path and adjust yourself to the consequences. I'm happy for all those who want to regrease their bearings regularly but they still have not been able to convince me to change from the fit-n-forget policy that I prefer to follow.
