Sizing a mixte frame
I have some old mixte frames being built into bikes, and noticed that the current one seems to have a very long head tube compared to a similarly-old road bike frame.
Two 70s Torpados, the mixte is 52cm crank to top-tube, 56 cm seat lug to head tube, 162mm head tube; the road bike (also hi-ten likely) is 55, 56, and 134.
Is this typical?
