Pros and cons
Corky Urban Helmet Mirror
Pros
- Field of view follows head movement — more active rear vision than a fixed bar mirror
- No handlebar real estate needed — ideal when the bar is full of computers and bells
- Lightweight (22 g) — barely felt on the helmet
- Ball joint allows fine-tuning to the degree
Cons
- 3M adhesive pad lasts two to three years before it needs moving or replacing
- Small lens takes practice to use quickly under load
Busch & Müller Cycle Star 80
Pros
- Real convex glass — sharp image without the plastic haze of cheaper mirrors
- Bar-end mounting damps handlebar vibration better than a clamp on the bar
- Gooseneck adjusts in every direction and stays exactly where you put it
- German B&M build — years outdoors without the mirror coating degrading
Cons
- Requires an open bar end — will not fit road or city bikes with glued-in plugs
- 80 mm can protrude slightly too wide on narrow city-bike handlebars
