At last, I've got hold of a report of Cannondale's disk brake/QR test
(you may recall that the CPSC asked them for help last year). It makes
interesting reading.

"Conclusion:

"The conclusion is that the braking action of disc brakes is not causing
the quick release mechanism to unscrew. This test is unable to cause
loosening. At this time there are no reasons to believe that anything
is missing or over constrained in this test."

0.5" bumps and 5lb of brake effort!!! What's missing Mr Cannondale is
realism.
