I am 6' with about a 33" inseam and found that with the 56 cm bike I didn't have much space when standing over the top tube compared with other 56 cm bikes. The 54 cm felt better but I switched out the stem on the 54 for one 10 mm longer. If you really want one I would try and see one in person and at least stand over the top tube, better yet go for a test ride. They are very nice bikes and I would get the new one with the trough axle.
