To top it off, this non-directional model includes a diamond-like coating for extra longevity.Features: Use: Mountain Bike (MTB), Road Speed: 12 speed Number of Links: 126 Size: 1/2"x11/128" Compatibility: SRAM and all other 12 speed drivetrain components Not Compatible: This version is not compatible with Shimano Missing Link Included: Yes (non-reusable) Durability Factor: 5Technologies: Titanium Carbon Nitride (TiCN) Tech: Enhancing resistance to wear and friction. Less friction is a central facet to drivetrain efficiency which allows for smoother shifting and chain interaction with all drivetrain parts. Shield Riveting Tech: A reinforced pin design that utilises a patented riveting process to expand pin surface and create the highest pin power to prevail against heavy loads and stressed shifting conditions. Diamond Durability: Similar to the creation of diamonds in high temperatures, DLC attains sophisticated chain roller and pin hardness through a unique thermal treatment to create advanced “diamond” durability for elevating friction resistance. XX-Bridge and Optimal Chamfering Design: Ensuring the best shifting performance. 100% compatibility, and non-directional installation. High Alloy Steel Material: Made from a special alloy steel composition, DLC reduces chain elongation, thus prolonging drivetrain life.Buy KMC Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
