5% more breathing capacity with wide bars ?? I can hardly believe it. The chest is a fixed cavity and you breathe by pulling the diaphragm down, drawing air into the lungs. The arms are unable to influence the size of that cavity. The diaphragm is several inches below where the arms are in all riding positions except facing backwards sitting on the handlebars steering with your hands behind your back.

I'd like to see a reference to the "so-called" research that purports that wider bars increase breathing capacity ! ! !
