Abstract
The present invention provides a torsionally stiffened, in-line roller skate frame having dual side walls having particular application to competitive speed skating. The frame is attachable to a skate boot and mounts a plurality of wheels for rotation in a common plane. A frame embodying the present invention includes first and second longitudinally extending side rails, each having first and second walls and each strengthened to resist skating generated twisting forces by reinforcing members extending between the first walls of the side rails and reinforcing members that extend between the first and second walls of each side rail. Each side rail includes a contoured wall portion and a planar wall portion. Preferably the frame is made of a graphite filled nylon material.
