postscript to prev reply... how different is this issue from when angles are speced and then folks 1)switch forks or headsets or 2) have unequal tire types and air pressures front to back. these would skew any angles from their blueprinted numbers. what's the point of measuring an intersection between the top and seat tube if you can't guaranty the frame is level? blueprinted chainstay specs don't have to equal the results you get with your tapemeasure on your assembled bicycle. e-RICHIE chester, ct
