By chance(?), I had a Stronglight fixed cup break in that fashion, a very long time ago.

It was my fault, thoiugh. I had allowed the pitting in the race to occur to a significant degree, although I don't recall the exact extent. The cup cracked when I was out for a bike ride, when I stood on the pedals to leave an intersection. It's a very weird experience to have a bunch of ball bearings shoot out of the BB and some end up in your shoe!

For me, it was a memorable lesson to keep on top of the condition of all bearings and cups and cones on the bike, and replace them when they start to show wear.
