New Park Tool IR-1.2 Magnetic Internal Bicycle Cable Routing Kit.

Kit includes:  Four plastic coated 250cm cables with attached magnets and unique fittings, an external guide magnet to speed operation and a small plastic storage case.  Newly updated in late 2016 to include a dedicated E-tube Di2 cable connector that easily pulls through a 6mm frame hole for Shimano Di2 internal cable routing.

Product Overview: 

• 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.  
• Opposite polarity magnets on cables seek and attach inside frame tubes, making it easy to route through frame entrances and exits.
• Compatible with any size of bicycle frame including tandems.
