Reserve 34|37 Turbulent Aero SL|Tune Carbon Spoke CL Wheelset

Thanks to the latest advancements in our carbon layup process, 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. 

Made for efforts like Jonas Vingegaard’s assault on Bola del Mundo in the 2025 Vuelta a España.

Our SL wheels come with carbon spokes and are only available together with our lightest hubsets. 

The Climber’s Wheel
These wheels are built to climb, but climbing isn’t just about weight. Our mixed rim profile maximizes aerodynamic efficiency, while reinforced carbon spoke holes maintain stiffness and strength. Engineered to win in the mountains.

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. Less weight. No shortcuts. 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, not just the wind tunnel. More speed. More control. Turbulent Aero.

Built for a Lifetime
All Reserve wheels are built around a simple principle: we have your back. That means no rider weight limits, an industry-leading Lifetime Warranty, safe semi-hooked rim designs and comprehensive customer service.
