Aerodynamic wheel design has shifted from pure depth chasing to understanding how air actually moves around a tire-and-rim system at real-world yaw angles. The Reserve 34|37 Turbulent Aero represents this evolution, using computational fluid dynamics and wind tunnel validation to optimize a 34mm front and 37mm rear depth pairing that prioritizes crosswind stability alongside straight-line speed. The asymmetric depth approach acknowledges that front wheel handling matters more than matching numbers, while the wider internal widths accommodate modern tire sizes without the aerodynamic penalty older narrow rims created.

Reserve developed the Turbulent Aero profile around 28mm tires as the design target, recognizing the shift away from 23mm rubber that defined earlier aero wheel development. The 24mm internal width on the front and 25mm internal on the rear create a smooth transition from rim to tire that reduces the turbulent separation responsible for both drag and the unsettling sensation when gusts hit the front wheel. This isn't theoretical optimization—Reserve publishes their wind tunnel data showing the 34|37 pairing outperforms deeper wheels in crosswind conditions while remaining competitive in low-yaw straight-line scenarios.

The DT 240 hub specification places proven Swiss engineering at the center of each wheel. DT Swiss's 36-tooth star ratchet delivers 10-degree engagement, meaning less freehub rotation before power transfer begins during accelerations and out-of-saddle efforts. The hub internals are serviceable and rebuildable, designed for years of use rather than planned obsolescence. Center Lock rotor mounting and 12mm thru-axle spacing match current disc brake road standards.... Read More
