Bicycle with Nanotechnology

There are companies that pursue high-end bicycles with nanotechnology: BH Bicycles, BMC and Pinarello. The BH G4 bike uses carbon nanotubes as filler material between the carbon fibers. There is no real evidence or claim that states that the bicycle is stronger or lighter after using nanotechnology. BMC has the same approach but vaguely states that "the carbon nanotubes are 20% stronger for practically the same weight." They did not define a definition for stronger nor is the word practically any helpful in describing the situation. Pinarello on the other hand says their bicycle can prevent impacts and sudden breakage. Where is the science and more reliable claims about the benefits of using nanotechnology on bicycles?
