As a kid I rode coaster-brake SS and very occasionally a 3-speed, then did not ride for almost 2 decades. I bought my first derailleur-equipped bike in 1998, and as the Houston and Texas Gulf Coast area is so flat, rarely shifted except as an occasional change of pace. I thought about converting an old frame to SS, especially after seeing a guy on either a fixie or SS pedaling in the area. Then found a Bianchi Pista on ebay, and won the bidding. I have really grown to love the perfect chain line and the simplicity. (FWIW, I like single-shot rifles too.) I am still deciding whether fixie or SS is best for me, but I anticipate that in the future, as long as I live in a flat area, I will not ride derailleur-equipped bikes very much.
