Outer plate near the roller/ pin. As for not being joined correctly, it was joined with a quick link and the break was no where the link.
Where did the crack appear on yours ?
But where's the control?I was curious if I wore down a number of chains sympathetically with the cassette, (try to get the cassette to wear down at the same rate as the chains). How far would I get, as in how much could a chain be stretched
Fatigue fracture through the rivet hole, where the stress is the highest:

But where's the control?
so had the metal sheared / snapped or had it twisted and pulled away from the pin ?
@Yellow Saddle view/comment?
You said it "mad observations". I just maintain my bikes and ride them, I don't log how many miles each chain does etc, I've better things to do with my time.
I still won't buy chains off Amazon or ebay. Has to be an online bike shop, or Decathlon for me. I'm also cautious about brake cables - e.g. Shimano - plenty of copies out there !
Me too.
Fair play to the OP for his insightful post though, it does make interesting reading.
I'm one of those heathens who changes the cassette and chain once a year.
I hope there is not a chain fairy in the same way as there is a puncture fairy - this telling the world I have never had a chain snap is worrying
