All these folks reporting on the mileage they get out of chains: it'd be interesting to know which chains.
Riding conditions matter, too: on a bike that sees a lot of dirt and gravel roads, chains will wear faster.
'Course, anyone's reporting is anecdotal, as chain wear is dependent on sooo many variables. As a general rule, I replace any time there is any doubt.
