Profile Sonic Aerobar
This product is currently sold out.
The Sonic/Ergo is designed to present minimal frontal area to create as little aerodynamic drag as possible. The main purpose of an aerobar is, of course, to get the rider into a fast position and, despite its fairly minimalist appearance, the Sonic/Ergo offers a comprehensive fit range for exactly this purpose.
Armrest Offset: -70mm to -2.5mm in 7.5mm steps
Armrest Width: 124mm to 290mm in 18.5mm steps
Armrest Stack: 60mm to 70mm** in 5mm increments
The extension length and rotation can be easily adjusted using the top bolt. There are 100 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1500 possible configurations. As a clip-on bar it is also possible to adjust the extension width and tilt easily. According to Profile Design, this is the most adjustable clip-on bar on the market (and in history).
Since the Supersonic (J5) was released as a premium bracket with market leading fit options and versatility, Profile Design wanted to bring similar options to the rest of their range of brackets and aerobars. By simplifying the extension clamp and shifting the wing forward to the bar centreline, Profile Design was able to meet these targets. As a consequence of this simplification, the Sonic is the lightest of their current brackets.
The Ergo armrest shares the flippable design of the rest of their new generation armrests. By swapping sides or rotating the armrests, smaller increments of movement are achieved – making it simple to fine tune a rider's position or match the position from their previous aerobar or bike.
The 35a extensions offer a 35deg ski bend shape. They are 400mm long to allow a wide range of riders to fit. The cable routing is designed to exit from the rear of the extension.
