Many derailleur chains use a “master link” that allows the chain to be installed and removed by hand. While this type of master link doesn't require a traditional chain tool, over time, dirt and corrosion can make it difficult to separate by hand. MLP-1.2 Master Link Pliers make removal and replacement of these master links quick and effortless. Simply insert the specially sized jaws into the master link. Then squeeze the handles top open or pull the handles to close the link. Compatible with all 5, 6, 7, 8, 9, 10, 11 and 12-speed derailleur chains that use a master link. NOTE: The MLP-1.2 does not work on traditional 2 and 3-piece master links (shown in the images) commonly found on single speed or 3-speed bicycles that use a single rear sprocket. These style of master links have the two pins attached on one side plate and use a side plate that clips on or a side plate and a spring clip to hold the opposite plate on. To remove this type of master link, use a needle nose pliers to slide the spring clip off, remove the outer plate and then remove the side with the two pins or remove the single side plate.
