KMC X9SL Superlite 9 Speeds Chain,Golden,TiN Coated how much kilometers you ride until it have wear?

What sort of wear? What sort of riding conditions? cleaned how often?

In terms of chain stretch it will last no longer than any other KMC chain, the coating aids side rub reducing friction.

its what I want to know. Thanks.

On my X9SL chain I first noticed the gold ti-ni coating wearing off at around the 300km mark... most of my riding is done on chalky/flinty ground, occasionally clay, 60% of the time conditions are wet so my chains/cassettes get clogged with mud quite often, I apply lube before every ride and bike is sprayed down after every ride, chain and cassette are given a full clean once every 1-2 weeks depending on conditions.

I removed the X9SL chain after about 500km and replaced it with a SRAM chain, comparing the 2 together with the same number of links the X9SL chain had stretched by about 8mm
