However, if you swapped chains every so often, then you'd get 2000k miles before needing a "new" chain... which by then the cassette could be replaced without replacing it prematurely. Basically, you'd be getting a brand new cassette at the same time as a brand new chain at the 2000k mark.


Atleast that's the logic I can pull from the idea... I have no idea if it works in practice... and the numbers were fictional.... and I tend to neglect my drivetrain anyways.
