Thanks to the latest advancements in Reserve's carbon layup process, the 34/37 SL wheels are lighter than ever without sacrificing any strength. Designed for Team Visma Lease-a-Bike, these wheels are made to lead the peloton up the world's steepest, most unrelenting climbs. While the 34/37 SL wheels are built to climb, climbing isn't just about weight. A mixed rim profile of 34mm front and 37mm 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.
