Profile Designs Sonic Ergo 52a Aerobar

The Sonic/Ergo is designed to present minimal frontal area to create as little aerodynamic drag as possible. The Sonic bracket offers an extensive fit range, low weight and easy adjustment. Combining this with the Ergo armrest creates an aerobar that will aid most riders in optimizing their position for both speed and comfort.

The extension length and rotation can be easily adjusted using the top bolt. There are 100 distinct position options achievable just by moving the armrests. The 52a extensions have a 52° angle for the grip. The rider can choose whether to hold high for the shrugged position or low for a more open, head up position.
