Yeah. Absolute idiot. It's like my back brake pads. I was thinking 'hang on it's only been 2 months since the last change but then you think "oh, 1,200 miles".900 miles is not much mileage for a chain, let alone a chainring.
Sorry - 5 times that is a lot of mileage for a chain. Not too surprised your chai rings are gone, too.
Apparently no problem on them attm shrug!You've not mentioned the cassette, this wears out far quicker than the chainrings so you'll need to factor that into your spending plans too.
