Abstract: A mirror assembly for mounting in the end of a cycle handlebar includes an insert member having a mounting post with a generally spherical head portion and a mirror mounting member having a mounting portion including a pair of spaced parallel walls with opposed recesses therein seating the head of the insert member for substantially universal movement thereon. The mirror mounting member also has a body portion with a cavity of circular cross section having a reduced diameter lip portion adjacent the outer end thereof. Seated within the cavity of the mirror mounting member is a mirror with an outer face of generally convex configuration and having its peripheral portion disposed under the lip of the recess. A resiliently compressible backing member adhered to the inner surface of the mirror bears upon the bottom wall defining the cavity to bias the outer face of the mirror against the peripheral lip of the cavity.
