Performance

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.
