What is your preferred top tube length? I was also looking for a big (62/63cm) touring bike for my self for awhile. The problem I find with the huge majority of them was really short top tubes even on a 62cm bike. I mean 56cm and under top tubes on a 62cm. I bought and resold three of them (Schwinn Passage, Schwinn Voyageur, and a Raleigh something) because of the top tube size. I eventually found a Nishiki Seral tourer that had a 59.5cm top tube and kept it. I put the most mileage on that bike than any other of my other bikes this year.
