Gulfmew Drop Bar Bike Mirrors are designed for road cyclists who want a clear rear view in a compact bar-end setup. Each mirror features a large 75 mm convex glass lens and a curved arm designed for drop-handlebar geometry. These are bar-end insert mirrors, not clamp-on mirrors. Remove the existing bar-end plugs, insert the expansion mounts into the hollow ends of compatible drop handlebars, and tighten them with the included hex keys. Compatible handlebar inner diameter: 14.8-23 mm. Each curved arm provides a 270° adjustment range, allowing you to position the mirror for your riding posture. After selecting the viewing angle, tighten the adjustment screws and confirm that each mirror is secure before riding. Periodically check all fasteners during regular use. The package includes one left mirror, one right mirror, and two hex keys. Install one mirror on your preferred side or use both for broader rear awareness.
