Getting ready to pull the trigger on a Kona Sutra 2023 and want to check my thinking on size as no one has stock for trial rides or fitting. My current best fit bike is a Trek Domane+ LT 2021 size 54. It took me a while to realize that the Sutra measurements use seat tube length and Domane use top tube length to designate bike size. Once realized I think a size 50 would match better than a 52 but the Kona size guide suggests 52 for my height and inseam. Here are measurements for my current Domane size 54 and Sutra size 50. Am I missing anything? Would a Rove 52 be similar enough frame wise to get a good fit approximation for the Sutra? I think my LBS has one of those to trial.
I’m 5’7.5″ and 30.5 inseam.
