It's wishful thinking. Actually, there is one position where the bag might have some aero-effect, and it is the position Franki-boy's champion ignoramus assures us it would have no effect -- and where Ridealot tells us experience is it works. That's behind the saddle, where the bluff sides of the bag would form a sort of Kamm tail to shortcut the turbulence of the passage of the cyclist and his bike, which translates directly into reduced drag. See the work of Professor Kamm between the big wars, and the graphic of both my Lancia Fulvia (the Zagato Kammback and the standard factory 3-box coupe) at speed with the skeins of wool streaming behind it in my Building Special Cars (Batsford, London and Robert Bentley, Boston are the most accessible editions).
