With its wider 23mm UD2 carbon rim, the Cosmic SLR 45 Disc 23 is the best-performing road wheel ever designed by Mavic. Not only does the 45mm airfoil rim slice through the wind with minimal drag, but it’s also amongst the lightest in its category. The external carbon layer features Mavic’s UD2 construction for a distinctive look and an even lighter rim laminate, saving another 15g per rim. This wheelset weighs in at only 1482g.
