jesus, have you even read this thread? the debate is not over whether chains get longer. everyone agrees they do. the debate is over the reasons.
some allege the link plates actually get longer due to the chain tension - this would be a chain stretching.
some allege the chain gets longer due to the cumlative effect of each pin wearing away at the link - effectively increasing the pitch and elongating the chain, not stretching it.
the first of these two is a myth and a misunderstanding. the second is correct.
