I can find articles that say O-ring chains are better, I can find articles that say standard chains are better, heck I can find articles that say the moon is made out of cheese. In my experience and application o-ring chains last way longer. . I can go through about 3-4 CS sprockets, and 2 rear sprockets on one O-ring chain. Ive had standard chains barely last a day. I certainly believe there are conditions where standard chains work better. So, what Im trying to say is there is no deffintate answer, the best advice would be to try each and see what works best for your application.
