Hey, I have decided to build my own singlespeed/fixed gear rather than buy one. I have been riding my old road bike for sometime and the frame is decent so why not use it as the basis for the new bike? IM not really sure on what size wheels I would need, or crankset for that matter. I would hate to buy something then have to send it back due to it not fitting correctly. I was thinking about going through bencycle.com. Can anyone give me some tips on how to figure what componets I would need?
