With the price of gas eating a hole straight through me, it's high time I bought a bike. I only live 3 miles from work, so it's fucking stupid to drive my car every day. The problem is I've never bought a bike before, and there's no way in hell I'm buying a new one from some high-priced shop.
I really want to get an older/vingtage road bike set up for commuting. I'm 5'11" and weight about 175, so what do I look for? What size bike do I need to get?
