About company
Donald Cassel started The Grind King in 1988 when he found a market for his invention, a special bolt that enables skateboarders to grind smoothly. In 1990 Cassel started to design the first truck with the intention of having the kingpin on the reverse side to be completely out of the way of grinds. After almost a year of tinkering and testing, the idea of a reverse side kingpin was fortunately abandoned and in September the first Grind King truck was introduced to the market.
