different conditions can affect a chain differently. Was cassette new? How much of the grindies didja have? How much more powerful did your legs become after the first 10000 km?

Did you check to make sure the new one wasn't made of plastic? They make everything out of plastic these days. Amazing, really.

10000kms on a single chain is exceedingly high. I would say if you're doing good high kms, you should replace your chain on an MTB at least at the latest 2000kms or to be safe every 6 months. If you leave it longer, generally the chain will be happy, but your cassette and crank will be worn out. When you replace the chain, the next chain will get attacked by the worn crank and cassette, hence the chain wll wear quicker than normal.

Yes and if your leg strength has increased you will progressively increase the strain on the chain, crank and cassette.

 

If you haven't yet replaced your Crank and Cassette after 11000kms, do this before putting on a new chain.
