I went from a 54 2017 to a 56 2022. The 56 seems to fit ME better. Im just shy of 5'10" and the specialized chart says I should be on a 54. My fitter suggested a 56 since I have long legs and Im a plus on the "ape index". i changed the stem to a 90mm and and got a zero offset seatpost. I couldnt be happier with the fit and ride quality. Im a 60 year old guy whose stem slamming days are far behind him. Try both and see.
