Un pneu de patin (14) est monté sur une surface externe (50) de la jante externe (18) du moyeu de roulette de patin (12). Les surfaces opposées (36, 38) des rayons en forme de lame adjacents (20, 20A, 20B), en coopération avec les surfaces opposées (32, 34) du moyeu interne (16) et de la jante externe (18), définissent des voies de passage d'écoulement d'air (40) à travers la roulette de patin (10). Chaque rayon en forme de lame (20, 20A, 20B) inclut une première surface rayon/arête (22) alignée radialement exposée sur une face (24, 28) de roulette de patin, une seconde surface rayon/arête (26) opposée alignée radialement exposée dans une région d'un plan central (CP) défini par la roulette de patin (10), et un corps (30) s'étendant de manière régulière entre les première et seconde surface rayon/arête (22, 26). L'invention concerne également des patins à roulettes en ligne (100) avec des roulettes de patins (10) selon l'invention, et des moyeux de roulettes de patins (12) pour ces patins (100).
