Many modern derailleur chains use a “master link" (also known as a "quick link" or "power link") that allows the chain to be installed and removed without driving out a rivet. 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 to open or pull the handles to close the link. Compatible with 5-to-12-speed derailleur chains that use a master link, including SRAM AXS and Shimano XTR 12-speed.

NOTE: The MLP-1.2 will not remove or install the style of master links with both pins attached to one plate and a side plate or spring clip that clips onto the pins. These are commonly found on older drivetrain systems or single speed bicycles. To remove these types of master links, use a needlenose pliers such as the Park Tool NP-6.
