The trick is bike frames do not get loaded like the tubes in that video. Of course carbon fiber composite is going to smash, because you are only loading the matrix (plastic) and you are placing zero load on the carbon fibers when you run over a tube on flat ground. Frames are loaded in tension, and some bending (which leads to tension on one side of the tube). Running over the frame simply loads plastic in compression. The video demonstrates nussin' Lebowski...it's nothing more than a cool party trick.
