The most important component of a surfskate is the trucks. In surfskates, the front and rear trucks are always different. The front truck is extremely responsive, while the rear one is more sluggish. This allows for extremely tight turns, mimicking the sensation of surfing. With this design, you can effectively pump and gain momentum from a standstill. The inventor of these trucks was Carver from the USA in the mid-nineties. In addition to the trucks, you'll also find bearings and specialized parts specifically for surfskates.
