"Changing your setback messes with your pedal stroke because it changes where your knees are in relation to the pedals. fa63 is correct, don't mess with setback to adjust reach. Reach should be adjusted with different length stems."
I understand this. First, adjust saddle height, then saddle setback (KOPS), then adjust reach with different stems. I'm just trying to get a little input on proper frame size for me. Does it look like the 56cm top tube works? Or should I go for 54-55?
