Key Features
The Wheel for Race Day, Everyday: From your local group ride to Pauline Ferrand Prevost’s Tour winning efforts, this wheelset is the silver bullet. The 42|49 is light enough to climb and gives you just enough depth to cut through the wind without ever giving up control.
Turbulent Aero Technology: Reserve’s aerodynamic testing protocol uses real-world wind data to develop wheels that are both faster and more stable out on the road—not just in a sterile wind tunnel. The result is more speed, more control, and less fatigue in unpredictable conditions.
Built for a Lifetime: All Reserve wheels are built around a simple principle: they have your back. That means no rider weight limits, safe semi-hooked rim designs for easy tire mounting, and an industry-leading Lifetime Warranty.
