The Profile Desing Sonic Ergo 39A Aerobar offers an extensive fit range, low weight and easy adjustment with minimal frontal area. The combination with the Ergo Armrest creates an aero bar that helps most riders optimize their position for both speed and comfort. The A II series extensions now allow the rider and bike fitter to fine tune the wrist angle without altering other aspects of the fit. The dimensions are optimized for use with the Plus Series armrests. The 39A is one of the latest versions of the reliable aluminum extension series.
Adjustment data armrests:
Offset: -70 mm to -17.5 mm in 7.5 mm increments
Distance: 124 mm to 290 mm in 18.5 mm increments
The Sonic Ergo is designed to have a minimal frontal area to create as little drag as possible. The main purpose of an aero handlebar is, of course, to put the rider in a fast position. Despite its rather minimalist appearance, the Sonic offers a comprehensive fit range for exactly this purpose.
