For the mathematically challenged, if your saddle tip is directly over the center of the BB, measure the distance from the BB to center of the seat, measure the seat length and divide by 2 and use the Pythagorean Theorem (if you know 2 sides of a right triangle you can solve for all angles) to solve for the seat angle. Here's a calculator site. http://www.1728.com/pythgorn.htm If your saddle tip is not directly over the BB, you need to make a right (90 degree) triangle and measure BB to center of seat, and center of seat to the point in space straight ahead and directly above the center of the BB. Use the above link to calculate.
