Christopher, Bear in mind that many older British bikes - especially those built before WW2 - had extremely long top tubes, especially in the smaller sizes. I'm referring to frames with say, 19.5" seat tubes and 22.5" top tubes. Certainly, such a frame, set up with 165mm cranks and 26" tires might not have overlap, even with fenders. But my 1973 Witcomb, which I suspect is typical of the era, has noticable overlap with 165mm cranks and 700x25mm tires. Of course, this is a racing frame which doesn't have fender eyelets. You can click on the following URL to get a good idea of the geometry. Note that the overlap is already apparent in the topmost photo: http://www.classicrendezvous.com/British/Witcomb_UK_FR.htm

I don't have photos of my circa 1960s Armstrong but it also had a bit of overlap. That was with 170mm cranks and 27x1.25" tires, but I never rode with fenders. If I had, the overlap would certainly have been quite obvious. Best regards, Fred Rednor - Arlington, Virginia (USA)
