About This Product...
The Sonic bracket offers a wide fit range, low weight, easy adjustment, and minimal frontal area. When paired with the Ergo armrest, it creates an aerobar that helps riders optimize their position for both speed and comfort.
The 39A is a new addition to our reliable aluminum extension range.
Performance
The Sonic/Ergo is designed to minimize frontal area, reducing aerodynamic drag. The primary goal of an aerobar is to position the rider for speed, and despite its minimalist appearance, the Sonic/Ergo offers a comprehensive fit range to achieve this.
Fit Data
The 39A extensions feature a 39° grip angle. Riders can choose between a high grip for a more shrugged position or a low grip for a more open, head-up position.
The extension length and rotation can be easily adjusted using the top bolt. There are 100 distinct position options simply by moving the armrests. With the addition of the risers, this bar offers up to 1500 possible configurations. As a clip-on bar, it also allows for easy adjustment of the extension width and tilt, making it the most adjustable clip-on bar on the market (and in history).
