Climb, sprint, and cruise faster with the Cosmic SL 40 Wheelset—lightweight carbon built for all roads
What Our Gearhead® Experts Are Saying:
"The Cosmic SL 40 hits the sweet spot—light enough to fly up climbs, fast enough to hold speed on the flats. Setup with UST tubeless is easy, and they feel incredibly responsive, especially with the new Infinity hub. For rim brake bikes, this is as good as it gets."
Whether we're hammering mountain switchbacks or rolling through high-speed stretches of tarmac, the Cosmic SL 40 Wheelset brings the perfect blend of lightweight climbing prowess and aerodynamic efficiency. With a 40mm NACA-inspired rim profile and Mavic's refined UST Road tubeless system, it's fast, responsive, and impressively smooth across variable surfaces.
New flat double-butted spokes and the Infinity hub platform cut rotational weight and boost stiffness, giving us punchy acceleration and effortless speed through corners. Engineered specifically for rim brakes, the carbon brake track uses Mavic’s iTgMax technology for confident stopping in all conditions. From solo efforts to big days in the saddle, the Cosmic SL 40 brings race-ready performance to every ride.
