Aluminum bike frames could have double-butted and triple-butted tubes that experience different thicknesses, allowing the frame to take care of high-stress points on the end of the tubes with no need additional weight throughout the middle. Double-butted frames add extra subject material at every end of the tube where additional strength is needed. Triple-butted frames use the similar process, but reduces weight within the center much more.
