Profile Design ASC Pro 43 Aerobar Extensions | 350 mm

The Profile Design ASC Pro marks a return to the one-piece aerobar concept—an idea the brand pioneered nearly two decades ago with the Sonic Stryke. Built for professionals seeking the ultimate blend of comfort, aerodynamics, and strength, the ASC Pro delivers an integrated solution with zero compromise, directly addressing the demand for custom-fitted performance setups.
