I disassembled and cleaned and regreased the front hub. The cones have some pitting, but what's the Clunker Challenge without that? The rear is in much better nick and should roll nicely when I am done.
I also hit my favorite LBS right at opening, before the no-hvac upstairs got too hot and scored a pair of used IRC 700x25s with mismatched labels - Coleman let me have them for $10 + tax. So now I’m at $25.70.
EDIT: Took more tweaking than usual, but now the rear wheel spins smoothly on new grease! Hopefully tomorrow I can reassemble the complete bike!
