Reserve 57|64 SL Tune Hub Carbon Road Wheelset

Built for riders chasing uncompromising speed, the Reserve 57|64 SL Turbulent Aero is Reserve’s pinnacle aero road wheelset. Designed for flat-out road racing, crits and fast group rides, this mixed-depth setup pairs a 57mm front rim with a 64mm rear rim to maximise aerodynamic efficiency while preserving control and stability in real-world conditions. Reserve describes it as the brand’s most aero-focused wheelset, now made lighter without sacrificing stiffness, strength or durability.

What sets the SL version apart is its no-compromise construction. These wheels use an advanced SL rim layup, carbon spokes, and Reserve’s lightest wheel system configuration, built around Tune hubs and a 24-spoke layout. The result is a claimed wheelset weight of 1,470g including lock rings, valves and rim tape, which is impressively light for a deep-section aero wheelset in this class.

Reserve’s Turbulent Aero development process is aimed at more than wind tunnel numbers alone. According to Reserve, the rim profile is shaped using real-world wind data to create a wheel that is not only faster, but also more stable on the road. That makes the 57|64 SL an appealing option for racers and serious performance riders who want deep aero speed without the nervous feel that can come with traditional high-profile wheels.

The rim dimensions reflect its modern race intent. The 57 SL front rim features a 25.4mm internal width and 34.3mm external width, while the 64 SL rear rim uses a 24.4mm internal width and 32.5mm external width. Reserve recommends tyres from 29mm to 40mm, giving riders flexibility to optimise for road racing, rougher road surfaces or all-day high-speed riding. The rims use a semi-hooked bead and the wheelset is offered in 700c, with 12x100mm front / 12x142mm rear spacing, Centrelock disc compatibility, and XDR or HG-EV freehub options.

Reserve also backs the 57|64 SL with a strong ownership proposition. The company states that all Reserve wheels are built with no rider weight limits, an industry-leading lifetime warranty, and a focus on long-term support and durability. Spare carbon spokes, driver bodies and Centrelock rings are also included with the wheelset.

For riders who want Reserve’s most aggressive aero road wheelset in its lightest and most advanced form, the 57|64 SL Turbulent Aero delivers outright speed with race-day intent and real-world control.
