After years of marketing research on the bike mirrors, Hafny found out that most of the bike mirrors break from the crashes during the ride or parking. Furthermore, some mirrors can't stay in place after only a few months of use. Being able to prevent crashes from the front and the behind is the most important part. If the mirror can't bear crashes, no matter how cool the features you have. It is still a failed mirror. Thus, we insist on using a full aluminum clamp to secure your mirror in the place. Moreover, the pivot joint between the mirror and the arm is flexible when the front biker hits you or parking in the garage. When we talk about durability, we really mean it because we have done the test from a trusted third party. Our mirror arm has passed the EU standard durability test.
