I'm curious about sizing one of these bikes--do you size them a bit larger than you would a regular MTB? Or do you just size them the same way?
GNA, the way I understand it, you want to go up a size or two, and nearly maximize stand over height. Traditionally MTBs are made with a more upright posture and lots of crotch clearance, when you build it for touring, you want a little more distance between the handlebars and seat.
I am going to get a 21" frame although my MTB sizing is 19.5.
