The ultra-light handlebar mirror is rotatable and completely retractable. This makes it quick and easy to adjust. For reasons of space and protection, it can be folded down to suit the situation. The Spin offers additional safety for all fast bikes such as e-bikes, racing bikes or mountain bikes. It is not only helpful for a better overview in city traffic, but is also useful for rides with several participants. With the spin mounted, the rider in front has good control over the partner's or group's whereabouts.
