Alleviating headaches and simplifying routing.

The Park Tool Internal Cable Routing Kit is a dream to those of us who love the clean look of a frame with internally routed cables, but feel a headache coming on just from the thought of routing the cables ourselves. No longer will you have to awkwardly fish cables through frames, getting hung up on sharp corners, and caught on internal frame obstacles, while hoping to land in the right spot— with the Internal Cable Routing Kit your life will be simplified. The kit works by attaching a cable with a magnet on its end to your shifter or brake cable, to slide through your frame, guided by an external magnet, pulling the cable smoothly through to the exit port, or feeding two magnet ends together for a smooth pull through. The kit includes four plastic coated cables that are 250cm in length, with attached magnets on the end, a super-powerful external magnet for guiding the cables, and unique fittings for different styles of cables, including hydraulic brake lines, shift and brake housing, shift and brake cables, and it includes rubber adapters enable routing for Campagnolo EPS, and Shimano E-tubes for electronic shifting. The system works on carbon, alloy, and titanium frames, but will not work on steel frames.

I've put it through the wringer

I tried my first go-round on derailleur cable replacement on an internally routed bike -- after an hour or two of cursing, some scares I decided to get this for any future needs. It made a bike build an exponentially easier effort and the subsequent derailleur cable replacement 10 times easier. Even used it for hydraulic hose and e-tube cabling inside handlebars. Could not recommend this tool enough -- must have for any DIYer.

Beware! It may not work at all.

If you have Campagnolo cables, the magnet doesn't work, as Campy stainless is of high enough quality to be non-magnetic. If the cable opening at the back end of your chainstay is small (like a Wilier Zero.7) none of the feeder cables in this kit will fit through the hole. The tool becomes a very expensive paperweight, since it only works for the part of the frame in which it is unnecessary. Thread and Superglue made a very cheap and workable tool for my frame and cable.
