The interwebs say that frame is "Tange 900 CR-MO Double Butted Tubes"
which means decent but not great tubing. Sounds like another solid
but unremarkable Japanese bike from the 80s. I'd make it into
a winter beater in a minute. Spray the tubes with framesaver on the
inside. Consider going for a 3-speed internal hub if the rear spacing
is right or you can cold set it (i.e. bend the stays) (I have no idea if you can safely
cold set a lugged frame). Convert away or just buy it and ride it until
you need to fix something.
