Did you get anywhere with this?
I've had a frame knocking about for ages, I rather cruelly parted it out on here years ago... but have recently been thinking about building it back up again...
I never really off-roaded mine, only messed about on it around town. A friend set it up as a tourer and did the Rievers route on it (I was on my Ozark). I have fond (and vivid) memories of how it felt to ride - very stable and planted, if not exactly quick.
Original spec had heavy wheels, non-indexed shifters - all a bit clunky. I fancy giving it another chance...
