Have you ever tried to get a wire, hosing or housing through a frame with internal wires had problems finding the hole out? Have you ever fishing wires with a spokes and looking for it with a light?
Those times are over, look at this:
Park Tool came with a new tool for the 2015 season and I got one at work a couple of weeks ago. Have used it for wires, housings. Gears, brakes, Di2 cables, Dropper post, you name it. 3 cables and a strong magnet makes it all go like a dream:
Almost 60€ but if you’re working with internal wiring at least once a week it’s worth every penny 🙂 Very fun to use it for the first times and seeing how easy it goes.
