What is the Shimano stainless inner shift cable for?

This is Shimano's standard 1.2mm x 2100mm stainless steel inner shift cable, the correct OEM replacement for Shimano mechanical shifting systems across road, MTB, and flat-bar builds. Stainless construction resists corrosion and maintains consistent pull weight over time. At 2100mm it covers virtually all frame sizes and routing paths without needing to cut before installation in most builds. A reliable, affordable cable for routine drivetrain service or new builds.

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).
