Well that's a new one. How the heck can that happen. And so did you just screw it back together?

It's an Italian thread so both sides are right hand threaded. It unscrewed itself. Didn't actually fall all the way out but close. I have it apart but need to get the correct spline tool for the campy pattern to get it back in tight. Their spline pattern is fractions of a mm different from the shimano one so the tools I have don't quite fit.

Ed, I believe the proper technical term for that tool is the "put-er-in-er" tool.

Funny, but heard from our son that his son had the same thing happen to his BB. Even though he's only 6, he's still a terror- much like Alex. Last summer he went over the handlebars roaring down their hill to acquire his first road rash case. More to come I'm sure.

Splines are piecewise polynomials; it's not clear to me how you will use one of these to fix a bike.

At least they (splines) are useful for O-mapping.

Actuaries used to use them , but that was a long time ago. When I was a young actuarial student almost 50 years ago, somebody found a spline and weights in the back of an old file cabinet. It was quite a curiosity.
