1974 Schwinn Sprint Geometry

I have a frame geometry question for the 1974 Schwinn Sprint (the model with the curved seat tube). Does anyone know what the seat tube angle is?

I've been searching on the net but no luck so far.

Thanks in advance.

Jeff

The 1975 Sprint, which I believe has the same geometry as the '74, appears to have a fairly conventional 73 STA. What surprises me is the 70 HTA, which seems extraordinarily slack. Even with the 70 HTA, though, the bike's fork rake results in what looks like reasonable trail.

The bent seat tube permits a short chainstay, resulting in a shorter wheelbase and a greater percentage of rider weight on the rear wheel.

I know i'm resurrecting a 2 (almost 3) year old thread... sorry

but, If you used a threadless stem adapter like this:

on a schwinn sprint, what degree stem would you use? a 73 or a 70?
