Trying to figure out seat tube angle.... tried this:
I thought the back hole on the Cervelo P2 was supposed to be a 75 degree seat tube angle, but when I measure from the center of the BB to the center of the back hole, it's more like 78 degrees, and the front hole 81-82 degrees. The bike is level on the floor (and conveniently resting upon the kids toys), which is verified by measuring the top tube which is at 0 degrees. What am I missing here? Thanks.
