Review on KMC 11-Speed Missing Link (Card of 6, Silver): The Ultimate Cycling Gear by Marcus Zimmerly

This is a good product. You'll need as much of the missing link as you can by hand, but then move the missing link so it's on the top line of the chain, and then pedal to set it (actually, this is the instruction they say when you put it on don't have tools). You need a tool to open it because it's really difficult to remove manually. The best installation and opening tool is the MLP-1.2 parking tool, it opens and closes unlike the KMC brand which has a separate opening and closing tool.
