or would I just be better off having a frame custom made?
I have also considered a Fit Benny L frame, which is available in a 20TT with 12.7 chainstays, but also with that steep 75.5 head tube angle. Would this be a better option?
I see that they claim to have minimized the dropout size on the Utopia, and that concerns me as I know my grinds are not, and will not be for a while, graceful or exacted in a way that would minimize stress on the frame. That gives me cause for concern.
