The present invention relates to a shaped tubular bar (10) for bicycle handlebars, which is produced from a metal tube with the aid of hydrostatic metal-forming. This method of production makes it possible to manufacture bars (10) for bicycle handlebars with complex shapes essentially in one step, it being possible already to match the obtained shape of the bar for the bicycle handlebars functionally to handlebar add-on parts to be fitted at a later point. <IMAGE>
