Profile Design Subsonic Ergo 39A Aerobar System  

Product ID: 92025_

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.
