Also, I get to type knurled nut again. Twice,
As I recall, they always threw out the valve cap immediately for some reason, even before snapping off that which must not be named.
Thinking about it now, my guess is that the nut decapitation was accidental the first time it happened. Since the tubular continued to hold air, the guy figured he might as well break off the one on the other tire too, to protect his Silca pump.
Maybe Presta valve inner cores are made of a better grade of steel now. I haven't seen a bent one in decades. They were very easy to bend accidentally with a pump chuck in the '60s.
