Well that narrows it down. Not trying to break anyone's brain here. I just thought someone might immediately recoginze it. All the extra clues I can tell you is that its a 700c. I just got the bike from a woman that knew nothing about bikes. She didn't tell me how long she had it, but it was hanging under her deck for the last 6 years. I'm just guessing that the tires are at least fifteen years old. She problably bought it the bike for next to nothing on a lark, rode it very little, and eventually put it on craigslist for me to buy. The bike shows some wear, not very much though. I though dating the tire might suggest how much or little the bike had been ridden.
