But you should be getting more life than you are out of the chains, even allowing that you are riding in slop which will significantly shorten life. How do you decide when a chain is finished, and how are you cleaning them?
I lube them about every 100 miles with "epic ride white lightening" chain grease - the stuff that at least says it's for wet weather, then I wipe away the excess. But that's it.
I guess I don't have the most robust method of deciding when a chain's life is up. I write down the odometer reading when I get a new one, but then when it's not shifting well, or making noise after I lube it, if it's been more than a thousand miles, I've been bringing it to LBS and asking someone if it's time to replace it, then taking them at their word...
I'm not sure if it's the Park Tool one or not, but the LBS the new bike came from used something like this to determine the chain has seen half its life:
