Stay out of harm&';s way with the Aventon Handlebar Grip Mirror. This mirror allows you to see vehicles and other riders approaching from behind, giving you more time to avoid potential collisions. Compatibility Please note that this bike is only compatible on bikes with grips that have removeable bar ends, such as these. If the grips lack a removable end cap, either a hole will need to be cut into the rubber end of the grip or the original grips will need to be replaced with a pair that has a removable bar end cap.
