This is a picture of my single / fixed. It is an old PX10 I found in a tool shack. It took me a while to think about what to turn it into. I now have it set up as a single / fixed. The Normandy rear hub has been re-spaced, and I use a freewheel or a fixed cog. I now ride 46/18 single. It also got new rims and tied spokes, stem, upside down north road bars, new seat post, used Brooks B17, used cranks, pedals, and a dura ace headset.
