I present to you, one broken lock nut. This was extracted from a Bontrager hub while servicing the bearings. I have never seen a lock nut split so perfectly in half before, and under such little pressure. Odd.
The picture probably doesn't really show what's goin' on here, but this is a Trek Madone and that little chip you see in the paint above the Trek logo on the seat stay is in fact a crack that wraps almost all the way around.
