Internal Cable Routing Kit

The IR-1.2 has been discontinued and replaced by the IR-1.3.

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 250 cm 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 6 mm 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!

IR-1.2 Features

Includes four 250 cm (98") cables with attached magnets and unique fittings:

  • Barbed adaptor — Threads into the end of brake & shift cable housing as well as hydraulic brake hose
  • Rubber adaptor — Securely holds electronic shifting wire such as Shimano® Di2, SRAM® RED® eTAP®, FSA® K-Force® WE®, and Campagnolo® EPS
  • Di2®-specific adaptor — Specially-designed connector clips into the end of the Shimano® E-tube® Di2® shift cable, and is perfectly sized to fit into frame holes as small as 6 mm
  • Reverse-polarity magnet — Used in conjunction with any of the other guide cables - feeds into the opposite end and meets the leading cable in the middle, aiding in routing on frames with tricky interior shapes

  • Factory Jackson Review The Park Tool IR-1 Internal Cable Routing installation kit is simply brilliant – the most brilliant ideas are always simple after all. If you have a bike with internal cable routing that isn’t a Santa Cruz Nomad – we’d recommend considering getting one of these installation kits. The IR-1 is a pleasure to use and will get you on the trail faster.

  • Mountain Bike Action Product Test The IR-1 is a welcome addition to any pro mechanic’s toolbox as a time and frustration saver when dealing with the internal routing that’s become standard on most high-end frames...For the serious home mechanic or professional, the IR-1 is a well-executed tool that makes stubborn internal routing a little more palatable.

  • Bicycling: Favorite Tools of Tour de France Mechanics Cannondale-Drapac’s Geoff Browne loves Park’s IR-1. As more and more bikes move to internally-routed brake and shifter cables, the magnetic kit offers mechanics an easy and effective way to thread cables through the frame. A great example of how tools are evolving to meet the need of modern bikes, the kit is a must-have for home mechanics with internally-routed cables.
