Abstract

A first mirror is mounted on a backing plate which is adjustably connected to the upper end portion of a first support arm, and a second mirror is mounted on a backing plate which is adjustably connected to the forward end portion of a second support arm. The opposite end portions of both the first and second support arms are adjustably connected to the forward end portion of a third support arm, and all of the support arms and backing plates are molded of a rigid plastics material. The rearward end portion of the third support arm is adjustably connected to a split collar or clamp which mounts on the handlebar support post or gooseneck of a bicycle. The mirrors and arms are individually adjustable and adjustable as a unit to accommodate bicycles of different sizes and bicycle riders of different sizes and to provide the rider with a forward and peripheral view when the rider has a comfortable head-down and streamlined position.
