Park Tool IR-1.2 Internal Cable Routing Kit 'Electronic' w/DI2 Connector

A great tool for fishing cables thru frames (and many other household tasks) , a perfect gift for every biker that already has everything but loves to tinker on his bike.

Take the guesswork out of installing cables, wires, and housing inside the frame. The IR-1.2 speeds the internal frame routing of shift cable/housing, brake cable/housing, electric wires, and hydraulic tubing on carbon fiber, Ti, and aluminum frames. Kit includes four plastic coated 250cm cables with attached magnets and unique fittings (now includes Di2 connector), plus an external guide magnet to speed operation. Opposite polarity magnets on cables seek and attach to each other inside frame tubes, making it easy to route through frame entrances and exits. Works with any size frame including tandems. Comes in a handy plastic box to keep it all organized with instructions inside.
