What is the mechanism that allows a chain to "stretch?" The links are rigid, so is it wear where the links attach, or something else?
Fatigue will cause metal to stretch

if that's say 10 thousands per pin/hole, that's nearly a mm for every 2 links...
Also this. M116 and M117 also break chains a lot on top of that.
Indeed. That's why I changed mine on the 450SL. Kind of a nerve-racking process too, as the chain gets drawn into a black hole while you turn it in... Once out, the old one was clearly longer than the new one.
