Abstract: A coupling for interfacing hand controls to a handlebar which provides for adjustment about multiple axes of rotation. A positioning collar having an inner cylindrical bore and outer spherical surface is mounted upon the handlebar of a bicycle, motorcycle or other like vehicle. A hand control for the vehicle such as a bar end, brake lever, throttle control, shift lever or clutch lever is provided with a receiving sleeve having an inner surface which is adapted to slidably engage the outer surface of the collar. The force imposed upon the collar by the sleeve may be reduced to allow adjustment of the hand control or increased to fix the hand control in the selected position. When being adjusted, the hand control may be repositioned along the longitudinal axis of the handlebar, rotated about the axis of the handlebar and rotated about an axes which are angularly deflected to the longitudinal axis of the handlebar.
