Internally installed cables and lines have several advantages: the tidy appearance, for example, but also better protection against dirt and weather. The serious disadvantage is that installation and maintenance are more complex. While external cables can be replaced very easily with a little practice, the invisible version requires expertise and dexterity.
The most important tool for installation is the liner - a plastic tube available in various diameters from bike shops. Before you get started, you should get an overview of the internal and external routing of the cables on your bike. The most important principle when changing internally routed cables: don't pull the cable out of the frame at the wrong time! Already done that? Then read the super trick from our workshop hero Dan.
