A skate wheel for an in-line skate has a skate wheel hub with an inner hub, an outer rim, and a plurality of blade-form spokes extending therebetween, and a skate tire mounted upon an outer surface of the skate wheel hub. Opposed surfaces of adjacent spokes, in cooperation with opposed surfaces of the inner hub and outer rim, define airflow passageways through the skate wheel. Each blade-form spoke has a radially-aligned first spoke-edge surface exposed at a first face of the skate wheel, a radially aligned opposite, second spoke-edge surface exposed at an opposite, second face of the skate wheel, and a blade-form body extending smoothly therebetween. The first and second spoke-edge surfaces are offset in a direction of travel of the skater by a predetermined arc of rotation of the skate wheel and hub. Also described are in-line skates with skate wheels of the disclosure, and skate wheel hubs for such skates.
