Abstract
A simplified roller skate with an improved assembly for quickly and efficiently adjusting the turning action of the skate. Front and rear wheel trucks comprising a single piece pedestal and tongue unit which are engaged in sockets formed within a main beam assembly, and are turned by selectively adjustable king pin assemblies. Further, structure for reversing the rear wheel truck is disclosed which reduces the stress and strain imposed on the skater's legs and ankles albeit with a reduction in turning capability.
