Abstract: A one-piece handlebar for bicycles composed of one or more composite materials. The handlebar may be configured as a curved drop style handlebar, bent, or swept forward style, or other configuration, for road or off-road use. The handlebar may be provided with different finishes and include a brake lever attachment area provided with a very rough textured finish. The handlebar may have two sets of indentations or cable troughs for the shifter and brake cables to be run recessed along the handlebar and not interfere with the riders hands. The handlebar may be hollow, with the wall thickness varied with more composite material in higher stress areas of the handlebar.
