The Supersonic 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.
The extension length and rotation can be easily adjusted using the top bolt.
The Supersonic bracket (previously known as the J5) is the premier model of the new generation Profile Design brackets. It offers easier adjustment and a greater fi t range than anything that came before it.
There are 80 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1440 possible configurations. As a clip on bar it is also possible to adjust the extension width and tilt easily. This is the most adjustable clip on bar on the market (and in history).
