This is a replacement for the stock Shimano R9100/9000 series derailleur cable set. It features the two inner cables, housing, ferrules, and cable ends. The inner cable has a new, enhanced polymer coating that assists to reduce friction for the buttery-smooth shifting that is a hallmark of the 11-speed Dura-Ace cable-actuated shifting systems.

The Polymer Shift Cable features this coating, which manifests in mini tube-shapes around the stainless cable. This has two major effects. The first is less surface area making contact with the inside sleeve of the housing- which reduces drag in the system. The second is that the cable can curve and bend more easily- again reducing friction. The space between the tubes also holds Shimano's silicone grease better.

Included within this complete Dura-Ace Polymer Shift Cableset is a 1700mm long, 4mm OT-SP41 housing that has been lubricated internally with Shimano's silicone Cable Grease. . There is a 2100mm inner cable and a 1800mm inner cable. Shimano also includes 6 assorted ferrules and two shift cable ends. The final small part is called the "Cover with tongue (nose cap)". This is a wear item used with 11-speed Dura-Ace and XTR rear derailleurs to reduce cable fray and is designed to be replaced with the polymer cable.

Note: This Kit does not include the 240mm segment of OT-RS900 housing, which is much more flexible, and required for proper set-up and function with the R9100/R8000/R7000 rear derailleurs. We do offer that separately, just enter 581930 into the search box above, or if you want a complete kit with the loop included, enter 581865.
