Vision Alloy-OS Base Bar (42cm) UCI legal
This flat (0mm drop) wing-shaped base bar is made from high-strength triple-butted 6066-T6 aluminum, allowing a complex aero shape at low weight. A broad, straight 31.8mm centre section gives plenty of room for stem and clip-on aero extensions. Outboard of that, the bar flattens into aerodynamic wing sections before curving into a powerful forward section. Full internal cable routing ensures that disrupted airflow is kept to a minimum.
