Developed exclusively to fit Shimano STI shifter/brake levers, the Miracle Road STI bicycle mirror makes it easy to tell when a car is pulling up from the rear. The mirror is easy to mount: just pull the rubber hood off the Shimano STI lever clip, slip the mirror base over the top, and then replace the hood. Once mounted, the mirror is located in the best possible position for watching the road behind. Just a flick of your eyes allows for a quick view of approaching cars or other cyclists. Best of all, the mirror doesn't get in the way of the STI levers, so you can shift and stop safely at all times. The Miracle road mirror--which attaches to either the left or right side lever--comes with all the necessary tools and is engineered to fit almost any STI lever. The Road Mirror will NOT fit on most Shimano STI levers installed on bikes after Spring 2010.
