Abstract
A wheel with an asymmetrical cross-section for use with a roller skate. The wheel also has a tread portion that can be easily and inexpensively replaced. An apparatus for multi-line roller skates that has two or three lines of wheels. The wheels in the center line have a coefficient of friction that is lower than the coefficients of friction of either of the outer lines of wheels. The wheels in the outer lines have asymmetrical cross-sections, while the wheels in the center line have symmetrical cross-sections. A multi-line roller skate that employs these technologies is disclosed. Also disclosed is a method for improving roller skate performance employing the aforementioned technologies.
