Mike, I can run a 100mm stem but then I get pain in my neck as I'm not so flexible anymore. I believe that unless one is sort of disproportionate, Riv bikes fit really well based on PBH. Make some allowances for flexibility if you will. With your PBH being lower than mine, I'd say we're both riding frames based on our PBH. Stem selection finetunes thr fit, along with handlebar height.
How this helps the OT I'm not sure... Unless he can find the recommended PBH range for the frame size he's looking at and knows whether he's of average proportions or not. I'd also suggest going for the middle of the range as usually there is some overlap.
