Spend a little more anf buy an o ring chain
I had that chain for 3000 miles and its just fine.. whats the diffrence with a oring chain ..?
O ring chains have o rings that hold the lubricant in the chain making for less need to lubricate as well as longer chain life
My bad I didn't see the non oring
Well I'll get n o.ring won't cost much more like you said, 30$ maybe
