PROFILE DESIGN SONIC/ERGO/39A aerobar

The Sonic bar offers a wide fit, low weight, easy adjustment and minimal front surface. When combined with the Ergo armrest, this creates a bar that will help most riders optimize their position for both speed and comfort.

The 39A is one of the newest versions in our reliable aluminum extension bar range.

Performance

The Sonic/Ergo is designed to have a minimal frontal area to minimize aerodynamic drag. The main purpose of the additional bar is of course to get the rider into a fast position, despite its rather minimalist appearance. The Sonic/Ergo offers a comprehensive range of fits for this very purpose.

Fitting information

The 39a additional bar has a 39° grip. The rider can choose to hold it high for a shoulder-raising position or low for a more open, head-up position.
