The Mavic Cosmic SLR 32 Wheelset is our go-to for high-performance road cycling, especially when it comes to climbing to new heights. The completely carbon fiber construction with an UD external layer is lightweight, durable, exceptionally strong, and features a 32mm airfoil shape built to slice through the wind. Each wheel features 24 patented lightweight aero steel spokes with Fore Carbon drilling technology that stiffens the rim exactly where it's needed, provides optimal weight savings, and eliminates the need for rim tape. The ready-to-ride UST tubeless technology improves riding comfort, control, and traction and makes it easier than ever to mount and change tires.
