Abstract
A bicycle frame having improved fatigue life of the frame. Cable entry/exit points for internally routed control cables are formed to produce strategically reduced stiffness zones so as to reduce peak stresses in the frame. Preferably, dimples are formed in the bicycle frame tubes with bulkhead walls deformed at an angle between 45 and 90 degrees and transverse to a line through the axial center of the tubes. Cable access holes formed in the bulkhead have a low friction plastic insert cable guide retained in the hole to provide aesthetic enhancement and weather seal for the tubing.
