Park Tool IR-1.3 Internal Cable Routing Kit

The Park Tool IR-1.3 Internal Cable Routing Kit removes the frustration and guesswork from internal routing on modern bicycle frames. Designed for mechanical cables, housing, electronic wiring, and hydraulic hoses, the IR-1.3 makes routing fast, precise, and repeatable on carbon fiber, titanium, and aluminum frames.

Using a refined guide-magnet system and multiple dedicated guide cables, this professional-grade kit allows you to route new lines—or replace existing ones—without fishing blindly through the frame. Everything stores neatly in a compact, shop-ready case.
