So, I added a 4th bike to my stable this past week. An old lugged steel falcon converted to a single speed/fixed gear. I rode around fixed for a few days but am now running the single speed (at least until I can add a second brake. It has a rack and a bell, rear caliper brake, shimano brake lever, all city track hubs, schwalbe marathons with reflective sidewalls, riser bars, and a big cushy saddle. I really like it so far. 45/16 single 15 fixed.
