I have an old bike that i really love. The power stroke is in exactly the right position and handle bar reach is good too. I'm trying to replicate the fit on another bike. In order to take the measurement, i thinking about putting a board from the seat to the handlebar, with a plumb line attached to the center. With the pedal in the 3oclock position, measure the height of the plumb line, and the length of the board from the plumb line to the seat and to the handlebar. I guess i need the length from the seat to the pedal and from the handle bar to the pedal as well to get seat and handlebar heights. I'll use the front of the pedal to measure from but I'm unsure where to measure the seat from since they are different shapes. Is there any systematic way to do any of this?
