ABSTRACT:
A slidebar assembly for adjustably positioning the handlebar of a bicycle or other similar vehicle includes a slidebar having a base end which pivotally attaches to the head of the bicycle stem and a slide block assembly which carries the handlebar on the slidebar so that the forward position of the handlebar can be adjusted in a slide motion. Hand accessible cam lock levers are provided on the slide block assembly for releasing the grip of the slide block assembly on the slidebar; a further hand-accessible cam lock lever is provided at the base of the slidebar for adjusting the pivot angle of the slidebar in relation to the handlebar stem which fits into the frame of the bicycle. Adjustment of the pivot angle of the slidebar in relation to the bicycle stem is provided by means of unique cam lock mechanism, which, when the cam lock lever at the base end of the slidebar is actuated, operatively releases the base end to pivot on the head of the handlebar stem. Due to the hand-accessible nature of the slide and pivot adjustments on the slidebar, the handlebar can be repositioned without the use of tools as the cyclist is riding the bicycle.
