Mavic Cosmic SL 65 Disc Wheelset The Mavic Cosmic SL 65 Disc Wheelset combines an aerodynamic profile with reduced weight to deliver maximum performance on flat terrain. Designed for disc brakes and featuring easy-to-use Tubeless technology, this wheel optimises power output with ultra-efficient performance. An excellent choice for fast, flat road races or windy triathlons, this wind-slicing carbon wheel incorporates progressive aerodynamic design and stable ride quality. The 65mm deep and 19mm wide NACA profile ensures low drag and stability in crosswinds. Profile Designed for Aerodynamics 65mm deep and 19mm wide NACA rim profile minimises drag and enhances stability in crosswinds. Perfectly suited for flat terrain and more reliable in challenging wind conditions. Extra-flat spokes improve aerodynamic efficiency. Faster Acceleration and Better Control Reduced inertia of the lightweight rim enables instant acceleration. Lighter spokes provide a snappier and more responsive ride feel. Disc-brake specific spoke lacing with thru-axle compatibility enhances control and braking performance. Perfect Balance of Weight and Acceleration Optimised rim inertia ensures instant power transfer and a dynamic ride experience.
