I think the designers and engineers over at Mavic has become mad scientist with their latest creation the Mavic Cosmic CXR 80. The claim is that these wheels have the lowest drag of any wheel that is out there in the market. These guys not only took into account the shape of the rim but as well as the tires and how it sits on the wheel. How exactly did they do this? Well the gap between the tire and brake track are fitted with a plastic blade into a channel on the rim to make it more aero. Price is heard to be around $2,800 and available sometime in August.
