Mavic Cosmic SL 65 Disc Wheelset

The Mavic Cosmic SL 65 Wheelset is built for riders who prioritize outright aerodynamic performance, sustained high-speed efficiency, and race-ready durability. With a deep-section carbon profile designed to excel on flat and rolling terrain, the Cosmic SL 65 is ideal for fast group rides, racing, and riders looking to maximize free speed on the road.

At the core of the Cosmic SL 65 is a 65mm full carbon rim, delivering significant aerodynamic gains at higher speeds while maintaining predictable handling in real-world conditions. The deep rim profile helps reduce drag during solo efforts and breakaways, making it especially effective for powerful riders and speed-focused road builds.

Optimized for modern tubeless road tires, the Cosmic SL 65 supports wider tire widths that improve rolling efficiency, grip, and comfort without compromising aerodynamic advantage. The tubeless-ready design allows riders to run lower pressures for increased traction and reduced puncture risk, an important benefit during long, fast rides and rougher pavement.

Mavic’s proven carbon construction balances stiffness and durability, providing efficient power transfer during hard accelerations and confident tracking at speed. Paired with Mavic’s reliable hub system and smooth-rolling bearings, the Cosmic SL 65 delivers consistent performance for riders who demand speed day after day.
