I'm replacing my old commuter frame and am buying a new frame. I am tall, just over 6'3" but my inseam is 34.5 and my boys aren't exactly hanging free at that point. From my measurments I'm told a 58-59 would be around prime for me, but my top tube would need to be around 59-59.5cm. The frame I'm looking at has either a 57cm with 57.5cm top tube and 33 inch stand over or a 60cm with a 60.5cm top tube and a 34 inch stand over. My current stem would work in length with the 60cm but i fear the stand over may be a little too high? Although with shoes on my legs would gain maybe half an inch. Or would the 57cm work better for me if i purchased a longer stem like a 120mm or 130mm?
