Easy Internal Cabling
Internal cabling is becoming increasingly common and it can be a nightmare to re-route if you haven’t done it before or are unprepared.
Many of the more thoughtful company’s have inbuilt sleeves running through the frame, from entry point to exit point, this makes the process a lot easier. However, for those bikes without the sleeves, hours can be spent fiddling, faffing and swearing.
I get asked time and time again is there and easy method to re-route internal cabling. Fortunately there is.
Follow our six easy steps to stress-free and easy internal cabling
- Get yourself some sewing thread, about 30-40 cm longer than the cable you intend to replace.
- Tie one end to the handle bars, put the loose end of the thread into the internal routing of the frame.
- Armed with a hoover, suck the thread through the routing and out at the exit point.
- Install the inner cable into the lever/shifter and through the outer cable, as you would normally, don’t forget the ferrule…
- Using a clove-hitch or a rolling hitch knot tie the thread to the derailleur end of the inner cable, being cautious start pulling the inner cable through the frame. The outer should follow, be careful not to snap the thread.
- Once the inner cable is visible at the exit point pull the entire lot through and install as normal.
Variations of this method can be tried.
- Follow steps 1 to 3, but this time use a longer piece of thread, twice the length of the cable you intend to replace.
- Try sucking the thread through the outer cable and tie a large knot in the end (large enough not to pull through the outer cable).
- Pull the thread and cable through the frame.
- Once the outer cable is installed in the frame install the inner as normal.
Its also useful to a have selection of picks, with various shaped ends and an old shaped spoke.
Bend the end of the spoke into a hook shape small enough to fit in the entry/exit hole on your frame. This can be used to hook out the inner cable or the sawing thread.
