Not all chains are created equally.
You will find that non O-ring chains wear quickly and tend to rust up.
Chain manufacturers like DID will sell different quality chains, some that resist elongation and stretching like many of their X-Ring chains with riveted master link.
I went with an EK X-Ring Chain this go around with Sunstar steel sprockets, in part due to cost, and also as a trial to see if I can get another 25,000 out of the set up.
My OEM front sprocket was quite worn, and the chain had begun to slip under acceleration, so I replaced the set about a month ago.
