Dominate wind and distance with the Cosmic SL 65 Disc wheelset—deep aero rims, fast hubs, and tubeless-ready ease
What Our Gearhead® Experts Are Saying:
"This wheelset is everything I want on flat, fast courses—it’s stable in crosswinds, accelerates quickly thanks to the lighter build, and the tubeless system really holds up on long race days. The Instant Drive 360 hub feels razor-sharp, especially when I’m coming out of corners or sprinting for the finish."
Built for those who race at the edge of aerodynamic performance, the Mavic Cosmic SL 65 Disc wheelset is a precision-crafted carbon setup engineered to cheat the wind and maintain speed over long, flat miles. With deep-section rims and lightweight construction, this wheelset helps transform steady effort into podium pace.
The 65mm deep, 26mm wide rims offer maximum aero efficiency without compromising handling in turbulent air. Mavic’s updated UST Road tubeless system simplifies setup, reduces rolling resistance, and improves ride quality at lower pressures all while minimizing flat risks. Flat aero spokes and a revised rim bed drop weight and sharpen acceleration.
At the heart of the build is the Infinity hub platform, featuring the Instant Drive 360 freehub system with rapid engagement and QRM Auto bearing preload for long-lasting, friction-free performance. Designed specifically for disc brakes with optimized spoke lacing and Center Lock rotor compatibility, the Cosmic SL 65 Disc wheelset delivers elite-level speed with real-world reliability—perfect for time trials, triathlons, or any day the goal is fast and faster.
