Abstract: An aerobar assembly is arranged to be mounted on a pillar stem, rather than on the handlebars, of a bicycle. The pillar stem in turn supports the handlebars. By mounting the aerobar on the stem, the range of adjustability of the aerobar is greatly increased, and the handlebar is subject to less torsional forces. The aerobar assembly includes a pillar stem having one end secured to the stem and a support structure at a second end for mounting an aerobar bracket, an arm rest support, and handlebar clamps. The aerobar bracket is arranged to permit axial adjustment of aerobar position, while the arm rest support is arranged to enable lateral, horizontal pivoting, vertical swivelling, and fore-aft adjustment of arm rest position independent of aerobar position. The handlebar mount preferably uses C-clamps that can easily be substituted to accommodate different handlebar configurations.
