Of course we all know that chains don't really stretch, right?. The elongation is due to wear in the link pivots/pins. I use the term, too, I just don't want to induce any misunderstandings...
I'm curious about this chain stretch thing. Theoretically, if the chain is longer, then the amount of wear on the pivots/pins will be multiplied by the greater number of links, creating more stretch for a longer chain for the same amount of actual wear in each link. Is this accurate? It's only a thought.
Still, the amount of "stretch" to measure would still be the same as for a DF bike chain, shouldn't it?
