I'm kind of wanting to look at buying a roadbike now. I want to try and spend under $700 and I want something that's durable with at least a decent frame that I can build off of.
I'm 240 right now, so I need something that will at least support that. Where should I be looking? I have no idea what size I should be looking at so that makes buying used difficult. What brands make an affordable road bike that's worth riding and not going to break down on me?
