Profile Design Subsonic Ergo 39A Aerobar System

The Subsonic aerobar system really is a wind cheater. It has been designed to achieve a lower stack height than standard aerobars with a clever inline bracket system to minimise the frontal area and reduce drag. The rider can choose whether to hold high for the shrugged position or low for a more open head up position.
