Cosmic SL 45 Carbon Wheel

What Our Gearhead® Experts Are Saying:

"The combination of aero efficiency and lightweight construction makes this wheelset a dream for fast road riding. The 45mm deep rims slice through the wind, while the Infinity hubs provide smooth engagement. The tubeless setup is hassle-free, making this my top choice for performance road wheels."

Speed meets control with the Cosmic SL 45 Disc 23mm, a wheelset designed for riders who demand aerodynamic efficiency without sacrificing versatility. The 45mm deep unidirectional carbon rims reduce drag and improve straight-line speed, while the 23mm internal width optimally supports modern tubeless tires, enhancing traction, rolling efficiency, and ride comfort.

Mavic’s Infinity hub platform ensures a stiffer, more efficient power transfer, allowing for explosive accelerations and smooth cruising. The aero-optimized flat spokes provide lateral stiffness while improving stability in crosswinds. Thanks to Fore drilling technology, the UST Tubeless Ready setup eliminates the need for rim tape, making maintenance cleaner and easier. Whether attacking climbs, hammering through headwinds, or pushing the pace on long rides, the Cosmic SL 45 Disc 23mm is the ultimate companion for high-performance road cycling.
