Abstract
Embodiments described herein improve airflow around bicycle wheels by providing for one or more of: (1) a optimum leading edge width of a rim for preventing early stall in cross winds, while still allowing for sufficient stability without undue drag, while not unnecessarily increasing the rotating wheel and drag on the frame; (2) a sidewall shape with a subtle camber angle at the leading, which defines a rate of radius change at the max width of the rim—which further defines the max width and placement along the chord length for optimizing the aerodynamic properties of the rim; (3) a continuous rate of change of curvature at a spoke face, which fundamentally improves the performance and stability by generating a side force at higher yaw angles; and (4) wheel sets with a wider front rim relative to a narrower rear wheel to assist in flow attachment in high crosswind areas.
