Smooth, Clean KMC Shifting

The KMC X12 x 126 Link Chain features a Double X Bridge link shape for clean, smooth shifting on SRAM EAGLE and Campagnolo 12-speed groups.

It features mushroom riveted pins designed to deliver the most powerful link connection on the market and allows clean shifting under heavy loads

The asymmetrical chamfering on the chain also avoids interference with connecting parts of the drivetrain (i.e. cassette, derailleurs, chainrings, etc.).

The Ti-Nitride coating on the gold versions creates an ultra-smooth surface that sheds mud and grit more easily, while also adding cleaner shifting.
