PROFILE DESIGN - SONIC ERGO 43A
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 despite a 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. 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 we wanted to bring the same kind of options to the rest of our range of brackets and aerobars. By simplifying the extension clamp and shifting the wing forward to the bar centreline we were able to meet our targets. As a consequence of the simplification the Sonic is the lightest of our current brackets.
The Ergo armrest shares the flippable design of the rest of our new generation armrests. By swapping sides or rotating the armrests smaller increments of movement are achieved – making it simple to fine tune a riders position or match the position from their previous aerobar or bike.
The 43a extension offers a ‘wrist relief’ style bend that is intended to allow the extension to hug to the arm for improved aerodynamics without sacrificing wrist comfort.
