I actually just tried the wrenchscience one and it says I would need a "55cm Center-to-Top / 53cm Center-to-Center" and "Overall Reach is :: 68.35cm Center-to-Center".
It gave pretty similar results to my fitment but I would rather go by what he did to me in person than the number the website spits out.
He said that the top tube and stem should be 69cm. On Lemonds website it says Effective top tube (is this the measurment you use? they have effective top tube and just top tube) of the 55cm is 565mm. The guy at the bike shop said I would use a 120mm stem instead of the 110mm that comes on the bike making it 68.5cm. He said my main concern was getting a bike with a long enough top tube but still allowing me to stand over the bike. This bike + stem should give me the length I need and I am able to clear the bike no problem.
guess I am just paranoid
