LIGHT WEIGHT BICYCLE WITH IMPROVED CHAINSTAY STRUCTURE AND METHOD ABSTRACT OF THE DISCLOSURE The two chainstay tubes of a bicycle are made of tubing of unequal rigidity, specifically the chainstay tube on the chain or drive side is made heavier, while, in the preferred embodiment, the other chainstay tube is lightened, in order to increase power train efficiency by reducing the magnitude of frame deflection caused by chain stress. In the preferred embodiment, the metal that is added to the chain side chainstay tube is taken from the non-drive side so that there is no net addition of weight.
