The Reserve 42|49 TA SLTune wheelset is built for all-around racing. Featuring SL rims, carbon spokes, and exclusive Tune Pico hubs, this wheelset was designed for Team Visma Lease-a-Bike. It is the ultimate all-around wheelset, engineered to lose every possible gram of weight without sacrificing the strength or reliability associated with Reserve. The wheels feature a lifetime warranty, no-fault crash replacement, and no restrictions on rider weight or tyre choice.
Turbulent Aero design keeps the handling smooth while delivering class-leading aerodynamic gains by pairing the shorter front rim with a taller rear rim. This provides more speed with more control. These wheels are fast enough for professional racing, having been used by Pauline Ferrand-Prévot to take the GC and the yellow jersey at the 2025 Tour de France Femmes. The SL wheels come with carbon spokes and are paired with the lightest hubsets.
The Wheel for Race Day, Everyday
From lunch rides to professional Tour-winning efforts, this wheelset is a high-performance choice. The 42|49 configuration is light enough to climb and provides enough depth to cut through wind without compromising control.
Lighter & Stronger
Built to be as light as possible without trading away strength, stiffness, or durability. Carbon spokes, purpose-built hubs, and an advanced SL rim layup work together as a system to provide less weight and pure performance.
Turbulent Aero
Reserve’s aerodynamic protocol uses real-world wind data to develop wheels that are both faster and more stable on the road, rather than just in the wind tunnel. This results in more speed and more control.
Built for a Lifetime
All Reserve wheels are built around a simple principle: the brand has your back. This means no rider weight limits, an industry-leading lifetime warranty, safe semi-hooked rim designs, and comprehensive customer service.
