Abstract
Improved cable guide for bicycle frames which has been found useful for improving the fatigue life of light weight bicycle frames and other stressed tubular structures. One or more welding or brazing-free dimple/bulkhead forming deformations produce strategically reduced stiffness zones so as to reduce peak stresses. The cable guide system also offers an improved method for routing control cables through the frame structure. A plastic cable nozzle insert is disclosed along with pyramid-shaped external dimples and contiguous bulkheads.
