Abstract
The skate chassis of the present invention includes a single, homogeneous, integrally molded upper boot and truck assembly which more evenly distributes internal stresses created in the chassis during use. The truck assembly may include a beam extending at an angle from the upper boot to form an axle hub for attaching the wheels. Also, an impact post may be integrally formed with the truck assembly to provide both vertical support and a surface for the rotation of the axle hub and beam. The one piece chassis provides improved handling and maneuverability while simplifying the manufacturing process.
