Park Tool MLP-1.2 Master Link Pliers

Many derailleur chains connect with a master link that's designed to be opened and closed by hand, but dirt and corrosion often make that difficult without a tool. The Park Tool MLP-1.2 Master Link Pliers make removing and reinstalling these links quick and effortless.

Simply insert the specially shaped jaws into the master link, then squeeze the handles to open it or pull them apart to snap it closed. It's compatible with 5- to 12-speed derailleur chains that use a master link (not intended for the traditional 2- or 3-piece master links found on single- or 3-speed bikes).
