That sizing chart accompanying the geometry chart is very useful; I say this in retrospect since I sold my (blue) 58 cm Ram over 10 years ago. But I’m 5’11” and the 58 fit me just right with an 8 cm stem and bar 3-4 cm below saddle. The size chart shows my height overlapping the 58 and the 60 and I’ve had perfectly fitting 60s (c-c) but I find many frames tall enough to be too long in the top tube. The 58 cm Ram’s 57 cm tt is just a wee bit longer than ideal — ideal = 56; the 60s at 58 would have been too long period without an abnormal stem.
I know Grant says, or used to say, that top tube length is relatively unimportant — you can raise your bar — but if you like your bar in a very particular place with respect to the saddle, that principle doesn’t work, or doesn’t work as well as a tt more proportionate to one’s build. As to the OP’s initial request: I’m only an expert about fitting one single person to a frame, and that’s me, but my sense from years of riding bikes that fit and bikes that didn’t fit, and from the thread scuttlebutt, is that the 50 might well be too small.
