Park Tool IR-1.2 internal cable routing kit

Take the guesswork out of installing cables, wires and housing inside the frame. The IR-1.2 speeds the internal frame routing of electric wires, shift cable / housing, brake cable / housing and hydraulic tubing on carbon fiber, titanium, and aluminum frames. Kit includes four plastic coated 250cm cables with attached magnets and unique fittings plus an external guide magnet to speed operation. Newly updated to include a dedicated E-tube Di2 cable connector that easily pulls through a 6mm frame hole. Opposite polarity magnets on cables seek and attach inside frame tubes, making it easy to route through frame entrances and exits. Works with any size frame including tandems. A true time and frustration saver!
