The Renthal R3 is a well thought of chain on the forum. I think the 116 link chain will fit most chain sprocket combinations. Usually comes with a split link and a rivet link.
Most commonly use a split link. I always carry a spare on trail rides incase the current gets too worn and knocked off by a rock.
Usually you end up using 2 split links per chain life, as they wear during use.
The ones in the shop are both o ring and split link. I won't use anything else. I always chang the chain when it starts to stretch and have seen the consequences on the trails of chains beyond this.
I would sooner have a split link chain as its something I have always had I have never had anything to do with an O ring chain
