This Shimano Dura-Ace gear inner cable is designed for smooth shifting performance and complements the top-of-the-range Shimano Dura-Ace 9000 gears system. The cable features a polymer coating applied in a spiral formation around stainless steel inner wire. This coating provides excellent support for silicon grease and reduces surface contact with the outer casing, resulting in a smooth, low-friction shifting action. The precision-ground round inner wires and anti-corrosion nature contribute to increased service life. It is suitable for front or rear mechs and can be cut to fit. Recommended for use with SP41 gear cable outer.
