Measure your handlebar and seat height. There is a balance of weight between butt and hands. Start out level and go up 1" (mark it) on one, ride for a few miles, evaluate, repeat until somewhat comfortable. I have five bikes and ride 3 a day sometimes, when I line them up- I have approx 2" drop on the handlebars. I used this system on each bike without comparing them first and they dialed in all the same.
