Probably won't work, but you could buy the bike, if it isn't right, which it probably isn't then you could buy a cheap sourced surly frame. Then you swap gear and sell the frame. Not as easy as it sounds, but you learn how to do some mechanical things, and you could save enough money to make it worth while.

I think that is the place that does outputs in French Fit, or if not, there is one out there.

Fit is the most important thing of all. So if you really are a "59", you surely don't want a 56. If you were oddball enough that you need a 56 when people say you need a 58-60. then you are almost certainly long in the torso, in which case you need the 58 with a bike with a sloping top tube, or a custom. Speaking generally. Unless the people who thought you were a 58-60, were ignorant, then you are not going on a 56. I am 6"1", and look normal enough, fit off the rack when I am in shape, but I am short in the leg and run a 56 59.
