So yeah, I have decided to take the plunge and invest some cash into converting an old Colnago road bike frame into a fixed gear ride. The problem is, I have no idea what to do. I have the frame stripped and ready to use, can I just buy a fixed-wheel for the rear and buy a chain, hook it all up and go? I am thinking it would be wise to find a flip/flop hub so that I can switch to SS if I need to, but someone told me that with a flip/flop hub I would need to buy a lockring as well. Is there a detailed how-to guide someone can recommend to me? Or is there an archived thread that entails all that I need to know? Thanks for any and all help.
