A newbie friend said he'd heard that carbon frames become more flexible over time, so he asked me about it. Before I laughed it off and told him it was silly, I thought I should do a quick Google, and found this:
"Carbon-fiber components actually do get softer with use. As the component flexes, the internal fibers break free of the surrounding resin and delaminate invisibly. When TOUR magazine tested carbon forks, they found that after 100,000 test cycles, some forks had lost a significant amount of their stiffness. Today, the European Union standards for fatigue resistance specify how much stiffness a carbon component may lose over the test cycle."
