Shaped with a sleek, aerodynamic design, the Polar Adjustable Bike Mount holds your M460 and V650 head units out in front of your handlebars without slowing you down on the road. It's designed to give you the best view of your computer/GPS head unit, so you can quickly glance at essential stats without taking your eyes off the road. It securely attaches to standard 31. 8-millimeter bars and takes up minimal space with its minimalist clamp.
