Thanks for the great info, folks. Ron- that link is for a Campy Chorus. are you sure it's the same as the Racing T? The T in Racing T is for "triple" (50/40/30 front). But you're right, I'm limited to 28T. I'll have to upgrade the rear derailer if I want to put on wider rear gears.
Joe/Ian- I'm running friction bar ends. Shimano, I believe. So I gather that they'd be flexible for any 7speed hub, but I may need to replace them if I step up to 8 or 9. Garth- good to know that there are some freewheel options. I still can't find a set of 650B's to try out. One LBS told me he had some built, but it turns out they were on a MTB "27.5er" (stupid confusing term). Disc brake won't fit in my frame. I think I'm just gonna buy a cheap 650B set and try them out. Then, if I like the size, I can rebuild my Phil's into some 650B rims. There's a local mega touring Atlantis owner who said he'll build wheels for beer.
