I was thinking about getting a hunko junko off of CL, and fixing it up as a CX bike. That would have two benefits, I would learn about the mechanics more and would result in a CX bike. I just have no idea what road bike frames will work as a CX bike. There is a thread in the CX forum that has a list of manufactures. I wonder if there is somekind of spec that I need to pay attention to, as far as size for the wheels and tires, or can you just put them on any roadbike frame? I need to do more research.
