4 mm diameter SIS OT-RS900 outer cable casing specifically developed for Dura-Ace R9100 rear derailleur. More pliable than SP41 outer casing, designed to work specifically with the Dura-Ace R9100 Shadow derailleur without B-tension spring. Lubricated internally along its length with low-friction silicon grease to reduce cable friction.
Special construction process makes for an axially stiff casing that transmits shifting movements accurately and quickly. Lined with a polymer sheath to assist with the smooth operation of the inner wire.

Not used for its intended rear mech use....have used to improve an integrated cable upgrade on my canondale supersix from the bars, down through the stem, steerer and then downtube to a junction. Lots of twists and bends which this outer copes with amazingly. Also comes with ferrules end caps as a bonus
