1. UPGRADES & SAFETY IMPROVEMENTS The new mirrors are injection molded to maintain a perfect curve. The mirror surface is polished to ensure a clearer view. The stainless steel material increases the mirror's impact resistance and the automotive-grade safety lens makes it less prone to shattering.;2. LARGER FIELD OF VISION: The bicycle rearview mirror has a slightly convex surface, which is manufactured through an embossing process and gives it a larger field of vision than a regular rearview mirror. It can significantly improve your safety when cycling on city roads.;3. INNOVATIVE DESIGN & FLEXIBLE ADJUSTMENT: The rotating ball joint where the mirror meets the stem is equipped with a special grain to maximize friction, so that the bicycle rearview mirror does not easily wobble even on uneven roads and you do not have to constantly adjust its position while riding. The universal ball design allows you to rotate the mirror 360° and adjust it to the desired angle as desired.;4. HIGH STABILITY The clamp under the bicycle rearview mirror is made of CNC-machined aluminum. Thanks to its high corrosion and heat resistance, it is not prone to rust, so you can ride with peace of mind even in the rain. The central clamping ring protects the handlebars from scratches and significantly improves stability.;5. VERSATILE COMPATIBILITY: The bicycle rearview mirrors fit handlebars with a diameter of 21-26 mm and are compatible with most bicycles, mountain bikes, e-bikes, electric scooters and kick scooters, so you can use them in as many different situations as needed.
