Mid 80s custom Davidson road bike clearance for maybe 28s, 25s for sure.
54.5 cm TT, ST is less if I recall correctly. A little small for me.
Lugged, standard tubing, threaded headset.
Rides like a dream, light, planes.
Has heavy powdercoat, probably needs the driveside dropout replaced because the wheel position screw is stuck in there. Horizontal derpouts, fenders only with kludge
Will come with a period correct 7400 group if you want it.
$200. Make it go away.
