I've picked up 6-8 garage sale middleweights with which I want to do a couple of builds. I would like information about the best components to use. For example, I have an old Hawthorne that seems to be a Frankenstein and has a Styria rear hub. Is it any good? Also have Komet, New Departure, Bendix, and an old 1960 Schwinn girls 26" with a Schwinn script front and a Schwinn rear. I know there is a single red stripe somewhere among them also. I'd like to save the best pieces and put the rest on ones to re-sell for garden/yard decoration bikes. Any help is appreciated! Thanks!
