I'm a 30" leg length and I tried the high seat position for the first time today and went for a three hour ride. I know it's only about an inch higher but I found it made virtually no difference in how I could flat foot the bike or in the riding position. Oddly (and I know this makes no sense) I felt I could sit even more upright than with the seat in the low position and the reach to the bars seemed no different. Have you tried the high position and what is your impression?
