My early-80's Bridgestone Altair LDT came with 40/36 (endearing); whereas same vintage Trek 720 is 36/36. I don't know if the Miyata 1000 was 40/36, unlike Schwinn Voyager someone mentioned. It'd be interesting what mass-produced 70/80's tourers came 40/36? Seems if someone is serious about designing a "true" tourer, 40/36 would be de rigeur...no?
