What Our Gearhead® Experts Are Saying:

"The Cosmic SL 45 Disc 23mm is my go-to for fast rides and long endurance days. The 45mm deep rims balance aerodynamics with stable handling, while the 23mm internal width pairs perfectly with wider tires for better traction and rolling efficiency. It’s lightweight, responsive, and just feels fast."

From high-speed breakaways to all-day endurance rides, the Cosmic SL 45 Disc 23mm delivers the speed and versatility we need. The 45mm deep unidirectional carbon rims are wind tunnel-tested to cut drag and improve efficiency, while the 23mm internal width provides the ideal platform for wider tubeless tires, ensuring smooth rolling and enhanced grip.

Mavic’s Infinity hub platform maximizes power transfer, and the aero-optimized flat spokes increase stability at high speeds. Fore drilling technology eliminates the need for rim tape, simplifying the UST Tubeless Ready system for a cleaner, lighter setup. Whether sprinting in the drops or cruising through rolling terrain, the Cosmic SL 45 Disc 23mm is built to keep us pushing forward with confidence.
