The Mountain Bicycle Mirror from Mirrycle provides a wide view of the cars behind you, so that you don't have to turn your head as you bike. Designed to fit mountain bike style handlebars, the three-inch round mirror mounts on your handlebar's bar end in minutes with the included wrench. Thanks to its convex glass and pivoting design, the mirror offers a wide field of view to any viewing angle of the road behind you--so that you can remain focused on the road ahead.
