The top level quality chain from the biggest chain manufacturer in the world, KMC.

The limited edition color range for the 12X series chain, Aurora! 

The X12 chain is a quality bicycle chain developed by KMC to meet the highest demands for Shimano, SRAM and Campagnolo drivetrain systems. Precisely engineered, dynamically chamfered plate angle provides a perfect shifting performance and a smooth transmission. 12 speed chain featuring the Double-X Durability and X-Bridge technology. Double X Bridge Shape for super-fast and smooth shifting

KMC uses the Extra Stretch Proof Pins. The 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. The less chain stretch = more power delivered to your drivetrain = more speed for the same effort



Сhain lube should be used regularly for best performance

It is also a good idea to use the new chain with your new ALUGEAR chainring
