I agree that choosing a size has to be based on the top tube length. The seat post can easily be adjusted, the reach...not so much. The 58 was obviously way too big for me. Way too big. The other one the LBS ordered and built up for me was a 56. I got the 56 only because it fit better than the 58 but the same LBS told me when deciding between 2 sizes on a CC, people generally choose the smaller of the two. I shouldn't have had to choose between the 58 and 56. It should have been between the 56 and the 54. Now I know.
I could get an even shorter stem but that would cost another $45 for a quality stem and leave me with two unused stems. I figure I might as well eat the cost of selling the 56 to to buy the 54. It'll only cost slightly more.
