Review on KMC 10 CR Missing Link (Set of 6, Silver) by Jon Johnson

Mounts to Campagnolo 10 speed 5.9mm chain. Will not work with old 6.1mm chains. Newer 5.9mm chains are called "Ultra Narrow". On this chain it is easy to install and works great. Much easier than using the pin that comes with a new chain. I suggest using the quick link builder tool available from Revain for around $10. Worth the money as installation is easy. Make sure you get one that installs and removes quick links. I will never go back to pins, these links are a much better way to attach a new chain.
