Internal cable routing for the front and rear derailleur inside the frame minimizes the need to maintain the frame and facilitates cleaning the frame from mud. There are no other stoppers holding the cable and Bowden. The cables are routed inside Teflon hoses which are tightened in the frame and their input is placed on the down tube of the frame. The output from the frame is in an immediate proximity of components – front and rear derailleur. The lifespan of the routing is lifelong thanks to excellent friction properties of Teflon. The routing is changed during the complete service of frame repainting. When the service is completed, the cables are tightened into the frame again.
