A Durable Chain Crafted For The Ultimate Adventures

KMC has been a premier chain maker for decades and while their X12 DLC Chain may not be their most technical chain, it is the best surface protected chain they offer, and it beats most component manufacturer options. This chain is compatible with SRAM Eagle 12 mountain drivetrains, Campagnolo 12 road versions, and Shimano's 12-speed mountain groups.

As a chain focused on maintaining excellent shifting performance with exceptional durability and resilience to grit and grime, the KMC X12 DLC Chain offers great long term value to those who ride in grit, dirt, and mud more often than not. The DLC (Diamond Like Coating) finishing adds incredible surface protection and can reduce corrosion and chain stretch due to this slow wearing exterior treatment. DLC promotes smooth glide, in combination with Double X-Bridge plate shaping to ensure super fast and smooth shifting with reliability. precision. The X-Bridge shaping on the outer plates adds torsional rigidity and stiffness.

This one-of-a-kind chain also features the KMC 12-speed MissingLink master link. This strong and truly reliable connecting link offers a tool-less way of installing and removing your chain for maintenance and cleaning. When it comes to giving your bike an upgrade, make sure to not overlook the KMC DLC 12x126 MTB Chain for all your mountain needs.
