ABSTRACT:
Bicycle handlebars designed to convert a typical 10-speed or multiple speed bicycle from a racing posture configuration to a posture configuration more suited to touring and commuting. The handlebars include grip portions which are elevated and rearwardly disposed in comparison to racing-style dropped handlebars. The grip portions extend rearwardly from the supporting structure of the handlebars at an angle of about 45.degree. with respect to the central axis of the bicycle. As such, the cyclist grips them in an anatomically natural posture. With this grip arrangement and the relative elevation and widthwise dimensioning of the handlebars, the cyclist assumes a posture eliminating compression of the cervical vertebrae and elongating the spinal column to an extent wherein the lumbar region becomes forwardly curved in a more natural posture resulting from a slight forward rotation of the pelvis.
