I noticed The Bridgestone RB-1 has a longer top tube: 57.5 cm. This is the longest I ever seen.most frames are 55-56 cm. Any out there with 56.5 or 57 cm?
Some current Soma/New Albion frames have a 57cm TT. I might do one of those if I do not get a vintage frame.
I should mentioned "small diameter steel frame" originally because some of these large tubes at 56 c-t-c creates a larger frame The only mention of a C&V frame is the Peugeot..
My question is only about top tubes parallel to the ground.
