Everlasting bike? Cranks? Anything else?

Nah.

I have the very rare UN71 and the unobtanium UN91 on my two road bikes. Been there a good 25 to 30 years. Also have ever lasting Dura Ace 7400 (1990ish) cranks and 600 ones from 1986

I keep trying to find a NOS UN72 of the right length.

But as I've got three new UN55s, and I'm 64 years old, I'm not too worried.
