We had a 68.5cm '78 LeTour come into the bike library last summer. I worked on it and test rode it before it went on the floor for check out. I'm 6'6" and it was slightly too big for my comfort zone. I thought we'd never check it out. I figured someone would have to be at least 6'7" to fit this thing. Well, a couple of days later during the next retail hours this guy walks in and he's gotta be 6'8" or 6'9". I say... "I've been waiting for you... here's your bike!" Needless to say, he was very pleased and surprised to find something that fit.
Beaverstuff, how tall are you, man?
