swapping same headset. do i need to pull/replace crown race?
 

I having some wobble issues on a new front end. There is a little play in the headset. Both headsets are new.

Is it necessary to pull and replace the crown race to swap parts?

Well, I'd assume the first thing you'd do is check you've adjusted the headset properly...

Assuming you have, if the headsets are the same model, there's no need to replace any bits that aren't worn out or damaged, no.

If it's a cartridge bearing headset the "crown race" is just a support plate that sees no wear. Both races are part of the cartridge so there is no need to change it if you are using the same model headset. If you have a loose bearing or caged bearing headset, the crown race is usually the first thing damaged and should be replaced if the headset is changed.

What would be wobbling in a correctly adjusted headset that would be corrected with a new headset? Generally any play once the headset is adjusted would be due to damage to the head tube or lower bearing seat.

interesting point, thanks for the input.

It's a zero stack set with caged bearings. And this heavy bike does have some miles on it. Better to be safe than sorry, especially considering it's a quick fix to get the race pulled at a lbs.
