How do you measure seat angle? On my Strada, I put the seat in the most extreme position and the angle of the seat back is 37 degrees from horizontal. I just ordered the M5 seat. They say that it should be about 25 to 28 degrees. Am I measuring correctly? Below is a picture of my bike with the seat leaned all the way back. The picture was taken from a long distance, so the distortion should be minimal.
