The ADH 1.2 handlebar is the ultimate aero handlebar. It is mounted on many of our bikes and is compatible with any regular, 31.8mm-diameter stem. Available in 4 widths ranging from 38cm to 44cm, it is designed to accommodate internal cable routing for a streamlined, aerodynamic build. Made from high modulus carbon fiber for stiffness and comfort, the bar is available in matt black or proteam colors.
