ive found a specialized crossroad hybrid bike that has been completely taken apart for a cheap price, i think the drop out is verticle but im not sure, would this make a good fixed gear bike?
Well, how cheap? If it has vertical dropouts it's probably not worth the time, money and sweat for you for any price imo. I don't think it's an especially good choice personally. Pretty much any random 70s/80s steel bike will be similarly bulletproof but more stylish and fun to ride imo.
