  • 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.

    Fit Data

    - Armrest Offset: -70mm to -2.5mm in 7.5mm steps
    - Armrest Width: 124mm to 290mm in 18.5mm steps (With Extensions at 100mm)
    - Armrest Stack: 60mm (no riser kit) to 130mm in 5mm increments (With aftermarket Riser Kit)

    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.

    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.

    - Extension Shape: A 50a extensions offer a 50degree ski bend shape.
    - The 50a offer a 7.5mm lateral shift per side. This allows the rider to get their hands narrower or wider without tilting the extensions so much that the shifters touch.
