You correctly stated that the carbon layup (i.e. the number and orientation of plies of carbon used) is likely to be lighter in areas where the frame isn’t typically as heavily loaded. You also correctly identified that CF is anisotropic, meaning that its material properties can be made to vary by direction, unlike metal tubes. I heard on one of the podcasts ...
