Missing Link Power Link for SRAM 12-speed chains
A chain is made up of a series of interlinking and alternating wide and narrow plates. Each plate is held together with a pin, or rivet, and the inner links of the chain articulate around this connecting point. A quick link works by replacing one “outer” chain link with a pair of slotted interlocking outer plates that feature permanently set pins. The force applied to a chain pulls these two opposing links into a closed position. Squeezing the links together (with enough force) will see the link come undone, which is why it’s also commonly called a quick release chain link.
