I test rode the Surly Disc trucker. I was in the largest size they make (64 in ? ) I barely cleared the standover height and in general this bike size seems a couple sizes than what I usually fit. I was surprised that it felt great to ride this bike. If I wasn't fixated on the notion that it was not 'supposed' to fit me I would have been feeling like this was the bike for me. I didn't buy it but it left me curious to return.
