Reynolds is using what it calls Dispersive Effect Termination DET on the Aero 58 Wheelset to eliminate the drag increasing balloon effect caused by tires being wider than rims. This delivers an aerodynamic benefit, increases lateral rigidity, increases your comfort, and decreases rolling resistance. The Aero focuses on mitigating turbulence, not accepting it like other manufacturers do. Testing performed at the A2 Wind Tunnel shows the Aero experiencing less drag in watts at 30. 75mph, at every conceivable yaw angle 0 18 degrees, than any offerings from Zipp, ENVE, HED, and Easton. This means that the Aero's handling sweet spot is extended to a window of 7. 5 degrees higher than the competition. One of the most amazing things about this new design is that as you go faster you don't have to exert as much energy to propel yourself forward the design starts to feed off the drag itself. Reynolds believes that every wheel needs to follow four engineering guidelines. The wheel must be lightweight, yet structurally sound. It must reduce turbulent airflow in order to create a low drag system. The aerodynamic efforts cannot compromise the steering and handling of the bike, and the wheel must generate an aerodynamic advantage from its lift drag ratio.
