Here's my 1973 24" Super Sport frame. Same setup, but I centered the rear "axle" midway along the horizontal dropout before measuring the angles.

Here's the setup.



Angle gauge "zeroed" on box beam.



Top tube has 1.0° slope relative to horizontal line through F & R dropout centers.



HTA is 72.5°.



STA is 71.9°.
