The Zefal Spy mirror is probably the only mirror of this type on the market today. It works well for riding a bicycle in all conditions when we want to see the space behind the bicycle. Women will also find its other potential functions, such as the ability to easily see themselves :). P.fits common handlebars, including Burza and Tornado bikes; it can even be attached to the frame. What is also important, the mirror is stable despite its inconspicuous design and appearance. In other words, it holds the set position fairly well.
