I'm 6'4" with an inseam of 37". So, most of my height is from my legs and not my torso. My current bike is a Giant with an XL frame. Looking to buy a new road bike, and they have a 58 that feels pretty decent. I can obviously adjust the saddle to a proper height, and the reach is a bit shorter, not putting too much pressure on my hands, which is good. In another words, it works. But, I still believe a 61 would be a better fit. Not having it in stock, I can't compare, so they will have to order one.

Any thoughts on which size may or may not be better?
