I picked up a Schwinn Le Tour today via Craigslist. It is my size and in pretty good shape. The only thing wrong with it was there was some lateral movement of the front wheel. I took the front hub apart tonight and internally it looks fine. I think the front hub was just loose, probably because it has these odd safety tabs position between the hub cone and lock nut. I think repacking the hub and adjusting it will fix the problem.
I've done some research on the internet for the bike and found a link to the 1983 Schwinn catalog. It appears that everything on the bike is original, including the saddle and Schwinn brand tires. The guy who sold it to me told me that he bought it new when he was in high school and it has been in storage for years. The serial number on the head tube badge indicates it was made on July 2, 1983.
I'm torn between fixing it up for myself or reselling it. Any idea what something like this would fetch on ebay?
