Abstract: An adjustable bicycle handlebar mounting assembly comprises stem including a portion for mounting to the stem tube of a bicycle and two parallel jaws for receiving tubular elements. The jaws are adjustable to enable the tubular elements to selectively positioned in the length direction of the bicycle. A handlebar mounting element for use with the stem comprises two parallel bores which are mountable to the tubular elements, and a jaw orthogonal to the two parallel bores for housing a handlebar. The handlebar is adjustable in the width direction of the bicycle. A clamping element comprises seats for housing two half-handlebars, and a fastening element. The clamping element enables the half-handlebar position to be adjusted relative to the stem, while maintaining the half-handlebars fixed with respect to each other.

Abstract: A mount for bicycle handlebars that is fitted with an elastic element to deaden the stresses transmitted by the front wheel and fork to the handlebars and so also to the arms of the cyclist. The mount is divided into two parts connected by an elastic element, the elasticity of which can be constant or regulated.
