5' 9" here with shortish torso and longish legs and arms.
One bike I currently have is a "Medium" because that's what spreadsheet specs said would fit me. Since this bike has an angled top tube, I can't rightly say what the size in centimeters it is. The seat was easy enough to raise, but I had to get a new stem and bars to move my hands forward and higher.
The other bike I currently have was labeled a "Large - rider height range 5'10" to 6'1" ". It measures 56 cm at the seat tube. It fits me much better as is.
