Profile Design Sonic Ergo 52A Aerobar

The Sonic bracket offers an extensive fit range, low weight and easy adjustment along with minimal frontal area. Combining this with the Ergo armrest creates an aerobar that will aid most riders in optimising their position for both speed and comfort.

The 52A is one of the newest versions of our reliable aluminium extension range. 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.

Fit Data The 52a extensions have a 52° for the grip. The rider can choose whether to hold high for the shrugged position or low for a more open, head up position
