Shimano Polymer Coated Shift Cable Set

For the Dura-Ace 9000 and Ultegra 6800 series, Shimano wanted to create a shift cable set that would provide the smoothest, easiest, and best shifting possible. To accomplish this they have brought together super slippery polymer coated, stainless steel cables, housing pre-lubricated with silicone grease, and sealed end caps to keep out the grime. This all results in a system which minimizes friction, making for best shifting possible.
