Sonic Ergo Aerobar

What Our Gearhead® Experts Are Saying:

"This is one of the most adaptable aero systems for riders refining position. The Sonic bracket keeps things light and aero, and the different extension angles make it easy to match grip height to your ideal posture."

The Sonic Ergo Aerobar from Profile Design is engineered to deliver aerodynamic efficiency through a minimalist frontal profile while maintaining an expansive fit range. The Sonic bracket is designed to reduce drag by presenting minimal surface area to the wind, yet it retains broad adjustability to help riders achieve an optimized aero posture.

Paired with the ergonomically shaped Ergo armrests, the system enhances comfort and stability during sustained time trial and triathlon efforts. Riders can select from three aluminum extension options: the 26A with a 26° grip angle for a lower hand position and open torso posture; the 39A with a 39° angle suited to a balanced, shrugged aero stance; or the 52A with a 52° angle for a higher grip and more compact aerodynamic profile. This range allows athletes to fine-tune wrist alignment, shoulder engagement, and head position to maximize power and control.

Designed for compatibility with standard 31.8mm handlebars and 22.2mm extensions, the Sonic Ergo system offers a lightweight, highly configurable solution for riders seeking measurable aerodynamic gains without sacrificing fit precision or long-distance comfort.
