:-) Don't know much about the legal system either, do you? I'm not an
injured party, therefore I'd have no standing in such a case.

<sigh> It's funny that you bring up the "real world." As I recall,
you were just claiming that these front axle loosenings and front wheel
pullouts don't happen. Yet "41" gave links to many instances where it
happened.

You claimed that manufacturers aren't changing their designs. Yet in
that same post, he showed that one manufacturer did change the design.
And "Kinky Cowboy" showed that another manufacturer was changing the
design.

You do show charming faith in the clamping force from a quick release.
I take it your mechanical experience is a little slim. Otherwise you'd
be familiar with threaded fasteners loosening under vibrations and/or
lateral movement.

So, in summary, it's obvious from elementary mechanics that there is a
tendency for the axle to be levered down and out of the dropouts.
There are many reports of loosening quick releases and dislodged wheels
due to this effect. There have been reports of serious injuries. And
manufacturers are beginning to make the tiny design modification that
would prevent this from happening.

But you still don't buy it! I'd think such cognitive dissonance would
be painful!

:-) But not vice versa, apparently!
