For 
• Effective tool for simplifying the task of internal routing • Efficient and succinct design
Against 
• The magnets connecting segments could be stronger

One of the many wonderful things about bikes is that the tech involved never stops developing - designs constantly evolve and new solutions to make things simpler, more efficient and better looking continually arise.

While internal cabling is hardly a new revolution, a given cable’s path is only getting more convoluted through frames of increasing levels of integration. This means that I’ve found my method (read ‘hack’) of routing cables previously sufficient is now no longer viable. A j-bend spoke serving as a hook, a torch and a fair dollop of luck just won’t get that cable where it needs to go any longer.

Enter Pro’s new Internal Routing Tool. Thankfully just as bike technology is ever-changing, so are the tools that facilitate the building of said bikes.

The tool is the first design on the market to house all the gubbins required to internally route cables (magnets and cable barbs, etc) in a compact and neat multitool-like format.

The Internal Routing tool is made predominantly from aluminium and in my experience has a robust construction.

Its layout and function is really quite ingenious: a 1.2-metre main wire tidily wraps around one half of the tool with a magnet on one end. There is a corresponding separate magnet segment housed on the tool that is removable and in turn threads into one of three attachments: a hydraulic hose barb, a brake cable barb or a Di2 cable stub.

There is a larger main magnet attached to the tool which can be used to guide the wire initially through the frame.

Whichever extension is required is unthreaded from the tool and screwed onto the other end of the separate magnet attachment. Then the barb attachment end can be inserted into the cable/hose that needs routing, the magnet end can be stuck to the corresponding main wire magnet that has been routed through the frame. The cable/hose can then be gently guided back through the frame.

Indeed, gently is the operative word in this case: while I appreciate the magnets’ strength is limited due to the need for them to be small, on a couple of occasions some of my less finessed attempts at routing saw the magnet connection broken inside the bike frame.

This left me to either blindly fish in the hope of re-establishing the bond (which occasionally worked) or cut my losses and restart the procedure.

Ultimately though provided care, time and attention is taken, this routing tool from Pro does an accomplished job of simplifying what is becoming an increasingly common and difficult task, and it has the added bonus of packing into a neat design that is well made and well thought-out.

If you are frequently internally routing cables the compact design, portability and overall quality of the Pro Internal Routing Tool would make it a worthy addition to your tool set.
