Mavic Cosmic SLR 45 Wheelset

The Mavic Cosmic SLR 45 Wheelset is engineered to deliver an ideal balance of aerodynamic efficiency, low weight, and real-world ride quality, making it one of Mavic’s most versatile high-performance road wheelsets. Designed for racing, fast group rides, and demanding endurance miles, the Cosmic SLR 45 excels across climbs, rolling terrain, and high-speed descents.

Built around a 45mm full carbon rim, the Cosmic SLR 45 sits squarely in the aerodynamic sweet spot (deep enough to provide meaningful aero gains, yet light and stable enough for confident handling in variable wind conditions.) The rim is optimized for modern road tire widths, improving tire shape, cornering support, and rolling efficiency while enhancing overall ride comfort.

Mavic’s advanced carbon manufacturing process delivers excellent lateral stiffness for responsive acceleration and precise tracking, while maintaining vertical compliance to reduce fatigue on long rides. Paired with Mavic’s premium hub system and high-quality bearings, the Cosmic SLR 45 offers smooth rolling performance and long-term durability suitable for both race-day and daily high-performance use.

Designed exclusively for disc brake road bikes and fully tubeless-ready, the Cosmic SLR 45 allows riders to run lower tire pressures for improved grip, comfort, and puncture resistance without sacrificing speed.
