Hey Mike, I recently reached out to Grant about upsizing as someone taller with a shorter pbh. I’m 6ft tall and my pbh is right around 840mm. Roman suggested a 60cm Platy when I initially reached out to riv to get insight into a good frame for me, and I reached out to Grant after seeing his on the Blue Lug visit video.
Now a proud owner of an upsized frame I’d say the only disadvantage is space between my saddle/stem and negative space one usually uses for bags. For instance, I wouldn’t be able to use the largest sackville rear bag because it’d be crammed between my wheel and saddle. And, my banana sack in the front attaches to my head tube. Both sacrifices I don’t mind, but I can see some being annoyed by. Otherwise I’d just say some people don’t love the aesthetic of the stem and seat post proportions, but I love my set up.
