Take the guesswork out of internal routing. The IR-1.3 speeds the installation of internally-routed cable, housing, electronic wiring and hydraulic hose into carbon fiber, titanium, and aluminum frames.

• The straightforward guide magnet system utilizes five long guide cables with unique fittings, which can be routed through the frame in a number of ways using the included guide magnet. Everything is neatly stored in a convenient compact case.
• New additions and updates from IR-1.2
• Di2 EW-SD300-specific adapter — Specially-designed connector clips into the end of Shimano E-tube Di2 EW-SD300 shift wire
• Double-threaded barb — Securely attaches new housing or hydraulic hose to existing housing or hose, allowing for easy replacement without redoing the routing
• All guide cables have been shortened from 250 cm (98") to 188 cm (74")
• The case has been upgraded to a round screw-top case, which fits the coiled-up cables better
