Depending on the frame, internal routing can be a nightmare. Sure, once it’s installed it looks clean and can keep the cables sheltered from dirt and the wind, but often installation can be frustrating to say the least. Best case, you’re pushing a piece of cable or housing through a full tube inside the frame. Worst case? You find yourself trying to coax a stubborn cable or housing through a hole at an impossible angle, completely blind.
Jag wire certainly isn’t the first company to devise a magnetic internal routing tool, but after seeing their new Pro Internal Routing tool in person, it will probably be in high demand once available…
A relatively simple tool, the Pro Internal Routing tool is basically a wand with two different magnets. On one end you have a super power, large magnet perfect for using through the frame with something magnetic on the other side. On the other end, there is a retractable and flexible wand with a smaller magnet on the end. Sized so that it will fit inside housing openings, the magnet is meant to effortlessly snap onto the corresponding magnet that is at the tip of the housing. The beauty is that you don’t have to see anything – just get the two magnets somewhat close and they snap together allowing you to pull the housing out through the opening.
If you need help seeing what you’re getting into, there is also an LED light built into the tip.
All of the pieces are kept inside the body of the tool in a storage capsule. Included with the kit will be barbs that thread into hydraulic hose or shift cable, as well as a special attachment for Shimano Etube wires. The magnetic dongle then threads into these fittings to ensure that it won’t pull out when yanking the housing through.
Estimated to cost around $35-40, Jagwire expects these to arrive around May.
