KMC X12 12 Speed Chain - Gold 126L

Introducing KMC X12 Ti-Gold Nitride 12 Speed Chain for SRAM and other 12 Speed drivetrains. A top level quality chain from the biggest chain manufacturer in the world, KMC.

Everything starts from the Extra Stretch Proof Pins that KMC uses. Everybody knows that flex steals power/watts/speed from you, be that in the frame, wheels, bars or even chain stretching. KMC's new pin and a riveting process "Flat Step" seals the outer plate with an impressive 350kgs of pin power, making it the strongest chain connection in the industry today. In layman terms, less chain stretch = more power delivered to your drivetrain = more speed for the same effort.

To shed valuable grams from the chain, KMC computer designed the inner plates and outer plates to achieve minimum weight and also enhance mud shedding characteristics.

Gear shifting was surely not overlooked and KMC's X-Bridge technology provides super fast and smooth shifting, whilst ensuring compatibility with all drivetrain brands.
