Hasta La Ideas

This little Corky gizmo was designed for cyclists with drop bars. It’s so named because you install it by “corking up” the end of the bar, and now you’ve got a handy rearview mirror (polycarbonate, not glass) you can flip out. It’s attached via a ball joint, so you can dial in the angle.

Made by French bike accessories company The Beam, these run $38.

They also sell a Corky Urban variant for ordinary handles. (Same price.)
