Joe,
I never said I did not believe the valve stem core could depress at speed. I
said "I don't believe the inner stem will release air at speed with the
aluminum cap and o-ring." That was the intent of using a sealed metal cap.
With respect to the pistons and rods: I'm an engineer and understand
mechanics of materials. I OK with sarcasm.

Jim your valve stems are perpendicular to the rim when
you look at it, at rest, why dont you spin your
wheel up to the equivalent rpm to match 169mph,
perhaps on a dyno, then
get a strobe light on it, see if your valve stems are still
straight up an down.....if they are rubber you might be in
for a surprise
as far as not
believing they valve stem core depressing at speed, well
thats your choice.........maybe you believe that pistons
and rods are always solid, and maintain their shape.........
