PROFILE DESIGN SONIC/ERGO/52A aerobar

PROFILE DESIGN SONIC/ERGO/52A

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 52A is one of the newest versions of our reliable aluminum extension bar range.

Performance

The Sonic/Ergo is designed with 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. Sonic/Ergo offers a comprehensive range of fits for this very purpose.

Fitting information

The 52a add-on bar has a 52° grip. The rider can choose to hold it high for a shoulder-raising position or low for a more open, head-up position.
