Abstract
An in-line roller skate includes a new lightweight frame and brake of synthetic material and embodies structurally interacting components which cooperate to counter and absorb the strain and shock of road bumps and vibration encountered at high speeds by heavy riders and which have in the past required heavy, metal frames. An improved wheel hub solves the problem of overheating bearings and wheel melting encountered by earlier skates and permits prolonged, high speed use of the skates on nonlevel riding surfaces by even heavy skaters under hot road surface conditions.
