Huh. That's a pretty solid statement, isn't it? No effect, eh? So have a look at these geometry charts, and tell us why manufacturers changed the STA unless it was for toe overlap. We notice that both STA and HTA change with frame size.

Some manufacturers hold STA steady with frame size change, but by no means all.
