Heavy-duty Profile design Sonic Ergo 35a and Bar Wing 10a 420mm Handlebar w/opkge

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 Wing/10a employs a truncated airfoil (Kamm Tail) to stay within UCI regulations while offering the performance of a much deeper section. This, along with tidying up the underside of the wing where the cables used to exit has led to a small improvement in performance. For optimal aero performance the bar should be set in the low position to increase the separation from the armrests. Base bar is 420mm width and Sonic Ergo 35a measurements are as follows: 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.
