I've been reading alot of threads on o-ring and x-ring chains. Most talk about DID, Renthal, RK, and Regina but I haven't seen anything about Primay Drive. The Primary Drive is the most affordable at Rocky Mountain and has a good tensile strength as far as x-rings go. Has anyone had experience with this chain? Going to get new kdx200 and thinking about putting x-ring chain on soon as I get it home. Also, can you notice any power loss with x-ring chains?
