I have to ask this... Are modern bikes, or at least some types of same, particularly prone to flats? I ask because although I am a new returnee to riding, my youth was spend on a bicycle - indeed one not too different from the `69 Raleigh I ride now. And I NEVER, no NEVER got a flat. Never. Nor to my knowledge did my parents who took my even then old Rudge (and my girlfriend's) down to FL when they retired and rode them and rode them and rode them.

What gives?

And just as I never got a flat I was never particularly fussy about air pressure either. Now I am, measuring and pumping in a few lbs each weekend. (I keep mine at 65lbs rear, 60 lbs front.)
