The different colored arrows on the model above illustrate the variety and intensity of stresses present in a bicycle frame during a pedal cycle.
Arrows indicate the direction of stress.
Brighter colors indicate higher levels of stress. We've developed a wide range of geometrically enhanced tube designs to address the specific directional stresses unique to every frame tube on a bike. No single tube shape can adequately handle the variety of stresses a frame endures. Changing diameter and wall thickness does help, but not as much as tube shape.
