I found a Cannondale Black Lightning frame on craigslist and want to know if I am getting a good deal. I posted the link to the ad below. He's selling for $250 but I talked him down to $160. My concern is that it's only the frame and I don't want to have to spend a ton of money adding cranks and wheels etc. I wouldn't mind going multi or single gear. Whatever would be cheapest/most convenient. Can anyone help me out?
