Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

Don't do anything until you have the new headset. 30.1 is an odd size, but I suspect it might be JIS, and the new headset will fit fine. If so, then mask the inside of the tube if you're painting it, so you don't have to ream out any overspray.

OTOH- is the new HS is also a sloppy fit, don't mask when you paint and the overspray will be your friend.
