The pinnacle of aerodynamic performance, all-out speed and no compromises. The 57/64 SL wheels are lighter than ever before and give up nothing in aerodynamics, stiffness or strength. Laced with carbon spokes, these wheels are ready for huge efforts at a moment's notice. These wheels are built to climb, but climbing isn't just about weight. A mixed rim profile of 57mm front and 64mm rear maximizes aerodynamic efficiency, while reinforced carbon spoke holes maintain stiffness and strength. Engineered to win in the mountains.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. Less weight. No shortcuts. Pure performanceReserve s aerodynamic protocol uses real-world wind data to develop wheels that are both faster and more stable on the road, not just the wind tunnel. More speed. More control.
