PARK TOOL INTERNAL CABLE ROUTING KIT IR-1.3

The Park Tool IR-1.3 is an internal cable routing kit that takes the guesswork out of feeding housing, hydraulic hose and electronic wire through a frame. Instead of trial and error with improvised wire, you work with dedicated guide cables and an external magnet that leads each line to the correct exit port.

The principle is simple: the guide magnet, moved along the outside of the tube, attracts the magnetic tip of the guide cable and walks it through the internal passages of carbon, titanium and aluminium frames. The kit includes five 188 cm guide cables, each with a different fitting: a barbed adapter for housing and hydraulic hose, a rubber adapter for electronic wire, a Di2-specific adapter that passes through frame holes as small as 6 mm, an adapter for Di2 EW-SD300 wire and a reverse-polarity magnet. Everything stores in a compact case.

How to use the Park Tool IR-1.3 internal cable routing kit

• Thread the housing or hydraulic hose onto the barbed adapter, or attach the electronic wire to the rubber or Di2 adapter
• Insert the guide cable into the entry port and lead it along the tube with the external magnet
• On frames with complex internal shapes, feed the reverse-polarity cable from the opposite end so it meets the other one in the middle
• Use the double-threaded barb to join new housing or hose to the old one, so the replacement follows the same path without re-routing
• Once at the exit, pull the guide cable out and detach the adapter

Why choose Park Tool IR-1.3

• Adapters for Shimano Di2 (including EW-SD300), SRAM RED eTap, FSA K-Force WE and Campagnolo EPS
• 188 cm guide cables, long enough for the longest routing paths
• Fewer unnecessary teardowns and less time spent hunting for the cable inside the tube
• Compact case that keeps every component organised

For anyone building and servicing bikes with internal routing, the Park Tool IR-1.3 internal cable routing kit turns one of the most frustrating shop jobs into a repeatable procedure.
