Wheel bearings rant

[RufusChucklebutty]

Is anyone else's piss boiling about throwing away good wheels because the bearing cups are worn out ?

What a waste of resources and money just for a pressed in steel cup worth a couple of quid, if only they had made them replaceable.



Rant over.

Some are better than others. I have 26 year old Dura Ace that still run on original bearings and races.

Cheaper hubs, if not regularly greased up will fail. At least with cartridge hubs you can swap out the worn bearings.

I don't buy cup and cone wheels now but I do have one back wheel on the winter bike (giant) that the cups were knackered after about 1000 miles, I still run the wheel but with the cones loose, I have did this on a few wheels over the years, just made sure the brake pads were slightly wider apart.

It's cheap 'case hardening' same as with the square taper shafts. I've got hubs from the 70s with thousands of miles on them that are still A 1

See my post about my plan to re-rim my Mavic wheel. It goes against the grain to throw away an otherwise good wheel but Mavic make rebuilds difficult.

Try Acycles_shop on Eblag. It's a French site that seems to specialise in old French equipment.

What's the cheapest bare hub with sealed bearings that I could rebuild my wheels with ?

Zenith are pretty good for bang per buck....

Something from Shimano. But I think you probably mean cartridge bearings which are not always sealed hubs.

Shimano hubs are cup and cone, and have properly sealed bearings.

I used to be an engineer, and I'm wondering if there would be a market for replacing bearing cups in hubs ?

It is basic engineering practice.

The only variable is the OD of the cup which could be a standard blank made from solid and ground to fit the hub pocket as needed. Reaming the pocket and pressing the new cups in could be done on the complete wheel no need to strip the hub out.

If the hub allows it converting to a cartridge bearing would be possible too.
