An in-line roller skate comprises a central box-like channel piece, a front bracket and a rear bracket are fixedly mated to an upper surface of the box-like channel piece. A plurality of bores are transversely defined near a bottom of the box-like channel piece and corresponding holes are defined in the front and rear brackets to align with the bores. A corresponding number of wheels, each defining a bore are rotatably engaged in-line with the combined box-like channel piece and front and rear brackets by a corresponding number of bolts extending through the front and rear brackets, the box-like channel piece and wheels. A distal tip of each bolt is threadedly engaged with a nut.
