That is simply not true. Regardless of frame material you cannot ride any bike anywhere. In the modern world of litigation all modern bikes come with "designated use" statements. They are usually over-stated, but you can't go riding bikes on terrain way beyond what they were designed for and expect them not to break. This has nothing to do with carbon vs metal frames.
