Well, it gets complicated from here. Saddle position fore/aft, up and down, determines whether your upper body is unweighted and you can efficiently produce power. You can find that sweet spot relative to the crank on different sized bikes, but if the frame is a mis-fit your center of gravity relative to the frame is in the wrong place and your reach to the bars may create shoulder and neck problems, or you end up cramped & slow.
I say, if you are going to plunk down good money for your
#1 road bike get the opinion of a knowledgeable fitter to advise you about size up or size down on that frame. You won't get a do over, and riding a mis-fit bike can be a long term annoyance.
