Profile Design Aerobar - Sonic | Ergo+ | 52ASA | Aluminum

The Sonic Ergo+ 52 ASA handlebar extension is an evolution of the extremely popular Aero Shaped Carbon (ASC) handlebar extensions, but in an elegant, high-performance aluminum design. The Sonic bracket offers a wide range of fit options, low weight, and easy adjustability with a minimal frontal profile. Combined with the Ergo+ armrest, this creates a handlebar extension that helps most riders optimize their position for both speed and comfort. Ergo+ takes the shape of the Ergo armrest and extends it to 124 mm to increase the contact area for your arms, thereby further reducing pressure on your skin. The 52 ASA is one of the latest versions in the proven aluminum series.

Performance

The Sonic/Ergo+ is designed to have a minimal frontal area to keep aerodynamics as low as possible. The primary purpose of an aerobar is, of course, to position the rider for speed—and despite its rather minimalist appearance, the Sonic/Ergo+ offers a comprehensive range of adjustments specifically for this purpose.
