muffles

Thanks, that's a pretty interesting article.

It seems to suggest to me that the reason a chain on its way out needs regular adjustment, is that the lack of grease in the joints means wear is inevitable every time the chain is used - hence it just wears more and more and more, and often needs adjustment.

It also suggests that the reason a chain "dies" is that eventually there comes a point where the rider doesn't oil it, or doesn't do it correctly, and then the chain starts to go. That's supported by the statement that a correctly oiled and adjusted chain doesn't wear out at all.
The other reason that occurred to me was that maybe some of the links happen to not get oiled enough (throughout its life) but I would have thought that one bad link would cause a lot of problems as it would wear through or something silly like that. So I'm not sure if that's a valid case or not.

Does that sound accurate?
