The latest Ultegra 10-speed chain
Please note that outer and inner links are of a different shape!
The outer links are specially designed to prevent chain suck
The inner links are specifically designed for optimal contact with the gears: better off under heavy load, efficient pedaling, optimal stiffness and less noise
It is not recommended to use this chain with a triple! You can use the CN-6600.
