Reserve 57|64 Turbulent Aero SL|Tune Carbon Spoke CL Wheelset

The pinnacle of aerodynamic performance, all-out speed and no compromises. Our 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. 

Chosen by Wout van Aert for stages like his winning sprint on the final day of the 2025 Tour de France.

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

The Wheel for Flat Out Speed
This is what speed looks like on the open road. 57|64 is our uncompromising aero wheelset designed to deliver the ultimate in aerodynamics and still be light enough to tackle epic climbs and all day efforts.

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.
