Meanwhile, all this talk about how the OP should have a 58 because he's six feet tall.... I'm 6'-0" and my frames are at most 55.5, albeit with a 120 mm stem, typically. Yes, I often ride pretty upright, as you can see in the photo at left (showing off after cresting a little hill, sitting up to wave to make it look as effortless as possible - the full image showed guys behind struggling on their way up. ) but on my latest fitting on a 55, we got everything set up where even on the tops, unless I really stretch out my arms, I've rotated my hips for a lower, more "pro" positioning.
