Hi,

Does anyone have experience replacing the cup in a Campagnolo record rear hub? At least one website has advised me not to do this--it will warp the hub--and therefore the entire hub should be replaced. But another has said they are replaceable.

This comes up because I bought a wheelset off eBay that turned out to have pitting in the cups on one side of the rear hub.

Thanks to one and all.

These are the wheels...

I have most of the basic tools, crescent wrenches, crank pullers, etc., but no vice, torch, power tools.

On a side note, better to return the wheels if the seller will pay shipping than try to fix this issue with the rear hub?

Return the wheels if you can. IMO Shimano hubs are the go; old six speed cassette hubs can usually be upgraded to 8/9/10.

Also, Shimano's cassette hub is the best design by far. It has the most outboard DS axle bearing by a long way, and the DS cup is easily replaceable along with the cassette body, which unlike others, includes the entire freewheel mechanism.
