Abstract
Abstract This invention relates to cycle handlebars, for mounting on a handlebar stem and supporting at least one brake and/or gear control lever (2), said handlebars having a handlebars body (10) having a central mounting portion (11). Known such handlebars create significant air turbulence especially during high speed cycling and thus result in increased air resistance. According to the present invention there is provided a pair of extension members (20) extending outwardly of the central mounting portion (11) along the trailing side of the handlebars body (10) on respective sides of the central mounting position (11) each said extension member (20) having, in transverse cross-section, on one side a generally hemi-elliptical shape and on its opposite side a concave surface (21) formed to fit the predetermined cross-sectional shape of the handlebars body (10) at said trailing sidethereof.
