That's my kind of half-step-plus-granny gearing -- I ran 48-45-34/13-15-17-19-21-23 on my PKN-10.
I, too, would favor barcons, and probably a set of drop bars with red tape, but Schwinn TwinStiks were an option on Paramounts of that vintage. The Brooks saddle fits right in.
Beautiful bike, nicely equipped. It would be as if Peugeot had made a PX-10 mixte, only better.
