Ok, figured I'd start this thread due to the common misconception that the Schwinn double straight bar frame was one year only, as I keep seeing people making this claim. It was not one year only, I have seen and or heard of them ranging from 1959 through 1962. Now, there are two different versions of this frame, One version, the double straight bars and seat stays are all one piece. On the other version, the double straight bars are independent of the seat stays. There are three models that I know of are the Typhoon, Tornado and Skipper. I do not know all the details on these, or what models were produced in what years using which version of this frame, but feel free to add what you know, and post pics of your double straight bar Schwinn, along with model and year. Here is my June 1961 Schwinn Skipper 24" with the frame where the straight bars and seat stays are one piece. My bike also has a bolt on kickstand, not sure what the other models have for kickstands. There is a 1962 Typhoon on one of the FB groups with the same bar/stay setup as my Skipper.
