: Okay DoD'ers, here's a goddamn mystery for ya !

Oh goody!  I love a puzzle.  Watson!  The games afoot!

: Today I was turning a 90 degree corner just like on any other day, but there
: was a slight difference-  a rough spot right in my path caused the suspension
: to compress in mid corner and some part of the bike hit the ground with a very
: tangible "thunk".  I pulled over at first opportunity to sus out the damage.

: Okay all you engineering types, how the f**k do you explain this ?  How can you
: rip a tightly fitting steel thread out of a threaded hole (in alloy) without
: damaging the thread in the hole ?  Is this some sort of hi-tech design thingo

Let me guess.  You were making a left turn, correct?  The edge of the stud
contacting the road caused it to turn and unthread itself.  If you had 
been making a right turn it would have tightened the stud.
