The recumbent will have less air drag than a typical upright. A time trial set up is close.
I have settled on 44/50T chain rings to go with the 13/16T sprockets on the 3 speed hub. A Sunlite handle bar bag mounted horizontally on top of the bars between the home made aero bars blocks much of the air that would pile up under my chest.
