Mirrycle MTB Bar End Mountain Bicycle Mirror, Black

These are great mirrors! This is my second one. They install fairly easily and securely inside the end of the handlebar. The mirror is easy to adjust and stays put once adjusted with variable adjustment tightness. The convex mirror provides ample view behind you. The only thing that some might not like is the mirror must have access to the hollow end of the handlebar tube. This generally involves cutting or drilling the handlebar grip. The grip on my new e-bike was easy to remove, after which I drilled a 3/4-inch hole through the end of the grip with a Forstner drill bit. I could have cut off the closed tip of the grip instead of drilling it, and this is what some might prefer to do. Good product!
