Abstract
In a bicycle frame adapted for internal control cabling, at least one control cable entrance port is located through the wall of the frame at a position ahead of the steering axis, such a port providing a bend-free cable path into and through the interior of the frame. This path passes laterally between the inner wall of the frame and the outer wall of the steering tube of a front wheel fork. A range of applicable port locations permits multiple internal cables to be installed together without interference. The frame configuration and associated cable guidance elements thereby facilitated provide direct cable paths to actuated devices such as a rear brake, front derailleur and rear derailleur. Because such paths are relatively short, incur minimal cable bending, and do not require outer cable within the frame, control actuation is characterized by particularly low levels of friction and elasticity.
