UNDERSTANDING COMPOSITE MATERIALS 101 Fundamental Reality of Carbon Composites All riders must understand a fundamental reality of composites. Composite materials constructed of carbon fibers are strong and light, but when crashed or overloaded, carbon fibers do not bend, they break. WHAT ARE COMPOSITES? The term “composites”...
Well designed “composite” or carbon fiber bicycles and components have long fatigue lives, usually better than their metal equivalents. While fatigue life is an advantage of carbon fiber, Cannondale still urges you to regularly inspect your carbon fiber frame, fork, or components.
INSPECTION OF COMPOSITE FRAME, FORK, COMPONENTS Cracks: Inspect for cracks, broken, or splintered areas. Any crack is serious. Do not ride any bicycle or component that has a crack of any size. Delamination: Composites are made from layers of fabric. Delamination means that the layers of fabric are no longer bonded together.
