Internal cable routing looks clean and hides housing from the elements, but running new cables through frame tubes turns into a frustrating guessing game without the right tools. The Park Tool IR-1.3 kit gives you a systematic approach: a flexible magnet-tipped lead finds its way through the frame while a magnetic pickup tool retrieves it at the exit port. No more fishing with coat hangers or hoping gravity cooperates.

The lead wire is flexible enough to navigate curved tubes and chainstay bends but stiff enough to push through without kinking. Once the magnet reaches your target port, the pickup tool locks onto it through the frame wall and guides it out. From there, you attach the cable or housing to the lead wire's cable hook and pull everything back through in one motion. The whole process takes a few minutes instead of the half hour of creative profanity that internal routing usually involves.

Park Tool includes a set of cable routing plugs in four sizes that insert into frame ports, keeping the lead wire from slipping back into the frame while you're working at the other end. The plugs also prevent cables from getting sucked into the frame during installation. A foam-lined storage pouch keeps everything organized and protects the magnetic tips from attracting every metal shaving in your toolbox.... Read More
