The measurements you're providing are close, but still don't get the information needed to say yes or no. The measurement that matters is saddle surface to pedal surface, everything else is just a subdivision of that. I'm guessing that you don't know the girth of the saddle that will come on the bike, but in my experience it's usually around 5cm from the rails to the part you're sitting on. I'll also note that the cleat attachment can add some thickness to your shoe/pedal interface, but it's not likely to exceed 1 cm, especially if you aren't riding your flat pedals with minimalist 3-7mm thick soles.
My take is that you'll be fine on the 58, unless you like to ride frames as big as possible.
Thanks for the reply. Actually, I am riding my flat pedals with minimalist (7mm or so?) thick soles, and it occurred to me as I read your post that I should have just asked about stack height differences between flat pedals vs clipless.
I think I'll be fine with the 58 but its going to be close.
