My scrapper dropped off a old shwinn tornado womens bike today, really cool diamond tread tire on the back (it holds air )but the front was missing. No big deal right? Just set on a spare and go? No the rims are funky, absolutly no tires fit them. Nd model d hub, schwinn made in germany front hub. Anyone care to explain this to me? Should I just part the bike out? Sell frame on cl? (I need parts off it) help?
