I forgot to mention that the Renthal kit from B & C comes with the exact number of links for that size of sprocket and a split link, which if installed properly is as safe as a closed link joint which need the chain riveter. After the original set wore ever so prematurely on my bike, I have always used those kits and never had one going wrong. I've found some old pics of the last kit I bought from them with the gold renthal chain too.
