You're right - a 56 bombadil would work. Yet another opportunity I let slip by, while I was waiting for the Clem, was Bill's orange twin top tube frame that he sold - but those don't really have enough clearance anyway. A new, built-to-order one starts to get toward custom price territory, so you're right also that its just as good as a starting-point template for something else, with 700c wheels and a little more relaxed ride quality. I'm coming to terms with the fact that I'll likely need to go this route. The hard part is that I really don't feel like I'm super-particular about my needs, and don't want something that's way "out there." I just want my size. A 56 Hunquapillar or, better yet - a 56 Clem, would be just perfect!
The Sam, which the Joe is based on, used to come in a 56, too. But from this exercise, I figured out what most of you probably already knew - that the Joe is not really intended to be a relaxed townish/mountainish bike, in the spirit of the mystery appaloosa or clem long bikes - despite the long chainstays. I mostly wanted to share the diagrams in case it was helpful for anybody else with these same kind of questions. (BTW, the diagrams do reflect the accurate seat and head tube angles - it's just hard to see on the screen shot. The only "guesses" are the angle of the downtube (which doesn't affect anything for this purpose) and how far the head tube extends above the intersection with the top tube. Everything else comes right from the geometry charts, and all jives perfectly. Also,I think that the way front-center is defined here, and works with the rest of these numbers, is as measured from the bottom bracket to the front axle. I was thinking the same thing as you until I actually drew these, but THAT is the key number that really affects toe clearance. Then, starting *there*, a slacker headtube just brings the handlebars back toward the rider at the top (decreases "reach" ). Oh... it occurred to me that for apples-to-apples comparison I should have used the 62 Atlantis, but its easy enough to extrapolate.)
