how should I get the bottom one out? It has no lip to hammer on from above.
Slide hammer/blind bearing tool.
For really close tolerance bearings, you really want to be removing them out as straight as poss. Screwdriver and hammer is gonna be skewing stuff and making it harder than it should be

Cheers, £25 on eBay might be a worthy investment, though another tool I don't want to own.
Fired an email of to Cane Creek, if they don't feel like replacing it I'll buy a 40 for the cups and spares.
@coventry_eagle 34mm headtube, maybe 33.9, seems pretty round. No corrosion on the bearing.

Think I just screwed my headset cup. Cane Creek 110 EC34, bearings were stuck fast so I encouraged it out with a screwdriver and hammer (I know), as far as I can tell they should be fairly loose.
Is this salvageable? Poss with some fine sandpaper on a circular disc in a drill.
Why would they be stuck so fast in the first place? CC website doesn't mention special tools for fitting/removal. I'm thinking ovalised HT maybe?
