The Sonic/Ergo is designed to present minimal frontal area to create as little aerodynamic drag as possible. The main purpose of an aerobar is, of course, to get the rider into a fast position. Despite a fairly minimalist appearance, the Sonic/Ergo offers a comprehensive fit range for exactly this purpose.
