This is the chain tool to end all chain tools. Topeak's well-named Link Meister works with all multi-speed chains, including 11-speed hollow-pin chains, regular pinned links and removable links. For pinned chains, an integrated chain hook holds the links during assembly, and an adjusting knob locks the pin in its correct alignment. For removable links, integrated pliers hold your power links for easy removal, a life saver. You've even got a chain-wear guide for precise measurements and storage for an extra plunger pin and chain pins.
