For the Love of Mediocre 80s Mountain Bikes

A classic '80s ATB would have the right stuff for an off-road tourer. Long Chainstays, level top tube, and 70*/70* angles are pretty much from the 'Ten-speed' era, and being more upright than a NORBA bike, would also take a drop-bar conversion (if you're so inclined) without the extreme positioning that would pose on a later bike.
