Also, worth noting if you haven’t realised it already… the Rufus Stone geometry charts appear to be listing the seat tube length C2C and NOT C2T
So the 57cm will be more like 58-59cm if measured to the top of the tube.
I say this because my medium is listed as 54cm, but that’s def the C2C measurement as it’s ~56cm CTT
So maybe I should retract my previous ‘size up’ advice as the 57cm RS might actually be bang on your size? But if you can fit on the bigger one then I’d still say size up.
See what the fitter comes back with and check out the numbers, reach/TT length/stack more important than seat tube anyway IMO
