Pre-stretched chain?

[mattr]

Half links do, the side plates start to straighten out.

So again, the system stretches, the individual component simply bends (or unbends, take your pick)

Fair to say chain elongates or get longer due to wear.

so it elongates but it doesnt stretch? tom-ah-toe toe-may-toe

question: you say the chain snapped, so presumably thats one link gone. Can you not live with chain one link shorter?

It doesn't elongate or get longer. The wear is all contained within the links, the pins and bushings wear, the rollers can then move further apart than they should. and the ID of the rollers also probably wears too.

116 links of old worn out chain should be the same length as 116 links of split fresh new chain.

Notice the groove worn in the pin, the roller being off centre and the edge of the bushing being worn.

Re:

I can see this one's got people riveted Chains slacken, not stretch – all the moving component parts of a chain become loose or slack through continued wear and tear and with the loss of their original industrial lube through regular degreasing/cleaning.

In other words, chain 'stretch' is an analogy or layman's term. :roll:

In other words 'stretch' is entirely erroneous and should not be applied to bicycle chain.

Is there any specific research and if so could you provide a link?

Finding all this a bit of a stretch and difficult to gauge.
