Awhile ago I saw a picture of an older classic-looking cruiser with two top tubes. Since then I have been trying to find a company that makes or made tin top tube frames. I have seen the retorted, but that’s not quite what I am looking for. That has twin top tubes an a down tube, but not the...ummmm....smaller-diameter-curved-bars-from-,head-tube-to-drop outs.....(what are those tubes called.). So I am looking for a more “traditional “ cantilever frame, but with double tubes. Any ideas?
