The 39A is one of the newest versions of our reliable aluminium extension range. 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. The 39a extensions have a 39° for the grip . The rider can choose whether to hold high for the shrugged position or low for a more open, head up position.
Fit Data
- The 39a extensions have a 39° for the grip . The rider can choose whether to hold high for the shrugged position or low for a more open, head up position.
- 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).
- The extension length and rotation can be easily adjusted using the top bolt.
- 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.
