Well, as I suspected, a couple of responses seem to confirm that my Follis, and probably the first lightweight I had, that 1972 UO-8, weren't designed for 27", but, in the case of the UO-8, had them slapped on for the US market. I personally don't remember 700C clinchers being common in the US until the early to mid 80's. In fact, when around 1984, I had some clinchers built as alternate wheels for my 1973 70-F Lejeune, they were still 27". Up until then, I had used 27' wheels on my UO-8 and my wife's Raleigh Grand Prix and sewups on the Lejeune, a Windsor Pro, and two Alans, but never really thought about the difference in rim diameter between sewups and 27" clinchers. I was highly annoyed to discover the need to adjust brake shoes when switching between sewups and clinchers on the Lejeune. It was only then I learned that there were 700C clinchers available which, unlike the 27" wheels, would interchange with sewups with no brake shoe adjustment. I had some 700C clinchers built (which I should have done in the first place), and, as the UO-8 and Grand Prix had been sold several years before, never got much use out of the 27" wheels.
I think the very late adoption of 700C clinchers in the US was due in large part to the dominance of the US market by Schwinn and Raleigh, both of whom designed the low and mid priced models, and even the Paramount touring version, specifically for 27" wheels.
