Shimano Optislick Inner Shift Cable - 1.2 x 2100mm

What is the Shimano Optislick inner shift cable for?The Shimano Optislick inner shift cable is a 1.2mm x 2100mm stainless steel shift cable with Shimano's Optislick coating, a polymer treatment that significantly reduces friction between the cable and housing compared to standard uncoated cables. Lower friction means lighter, more precise shifting action with less cable stretch over time, translating to more consistent indexing between service intervals. Optislick cables are compatible with standard cable housing and suit riders who want to improve the feel and longevity of their mechanical shifting system without upgrading to electronic. 1.2mm diameter, 2100mm length. Compatible with Shimano and most other mechanical shift systems. Sold as a single cable. For use with compatible shift housing (not included).
