ハンドルミラー

The 3" mirror is bigger than I expected and I can actually see behind me without turning my head. It holds its angle even on bumpy roads, though you do have to tighten the clamp down pretty firmly at first.

The 3-inch mirror is just the right size and the splash/crack resistant glass gives me peace of mind on rainy rides. It was easy to clamp onto my handlebar and I can adjust the angle without it loosening. Exactly what I needed for my commute.

Clamp fit my bars fine, but the left-side-only mount means I can't set one up on the right, which I didn't realize until install day. The 3" mirror itself gives a decent view once I finally got the angle right.
