Mysterious. How the hell did that happen in a design 100+ years old?

Yes, I'd have liked some technical detail. Although I realize that's not
the point of the article.

I will say, a three speed with coaster brake is a fairly complicated
bucket of parts. I still don't know what was wrong with the Shimano one
that I had to disassemble multiple times because of its second gear
skipping. It's working now, but I don't feel confident about it.

OTOH, there's not much to the brake part of the device.

Bad grease.

Interesting. We had some 25,000 V circuit breakers that failed to open for
exactly the same reason. Bad grease dried up and prevented certain moving
parts from moving when commanded to do so.
