Abstract
Abstract Cycle handlebars include a transverse element which can be connected centrally to a steering pillar and has two side extensions which extend forwardly and converge inwardly of the handlebars. Two further extensions extend upwardly from the side extensions and are connectd by a further transverse element. The handlebars, which preferably have a generally loop-like configuration, thus provide at least four different gripping portions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
A handlebar for cycles, particularly but no exclusively for bicycles for triathlons and speed trails, comprising: a transverse element adapted to be connectible centrally to a steering column of a cycle so as to define two first gripping portions of the handlebar, two side extensions of the transverse element, one at each side of the transverse element, extending forwardly and converging inwardly of the handlebar so as to define two second gripping portions of the handlebar, two further side extensions each forming an inwardly converging extension of a respective side extension so as to define two third gripping portions of the handlebar, and a further transverse element connecting the further side extensions so as to define two fourth gripping portions of the handlebar.
Claim 2
Dependent Claim
123 words
A handlebar for cycles, particularly but no exclusively for bicycles for triathlons and speed trails, comprising: a transverse element adapted to be connectible centrally to a steering column of a cycle so as to define two first gripping portions of the handlebar, two side extensions of the transverse element, one at each side of the transverse element, extending forwardly and converging inwardly of the handlebar so as to define two second gripping portions of the handlebar, two further side extensions each forming an inwardly converging extension of a respective side extension so as to define two third gripping portions of the handlebar, and a further transverse element connecting the further side extensions so as to define two fourth gripping portions of the handlebar.
