Ergo Sonic 39a | Profile Design

SONIC/ERGO/39A PROFILE DESIGN EXTENSION

The Sonic/Ergo is designed to feature a minimal frontal area to create as little aerodynamic drag as possible. The primary 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 full range for exactly this purpose.

The rider can choose to hold high for the raised position or low for a more open, head-up position.
