x2. BTW, there are many ways to measure fit on a bike, but for me, the top tube length is the most important (standover is nowhere near as important...). I'm 5'10 or so, and am quite comfy on a 54cm or 55cm road bikes with a 110mm or 100cm stem (my current bike has a true top tube length of 54.8cm). If I were a couple inches shorter, I would not hesitate to try a 53cm bike...
