I'm 6'4". I don't know my pubic bone height but my inseam is 36". I bought a 62cm LHT frame and built it up. I bought a long stem. The first time I rode the bike I felt like it was a long stretch to the bars. I also felt they were a little low. I found another stem on Amazon that had a much steeper angle - it is higher, but not so far out in front. Now it seems perfect.

I'd guess the 58 would be perfect for you, and you can tweak the reach with your choice of stem, and how you slide the saddle fore or aft.
