Darkstar PLG Grizzly Bull 8.5 R7 Skateboard Deck. Resin-7 Canadian Maple Construction. Width: 8.5", Length: 32.3", Wheelbase: 14.5". Full Concave / Steep Kick. Resin-Ply is the new standard in all wood skateboards. Epoxy is more aggressive than the normal water-based glue, which is the industry standard. Since epoxy is so strong, less of it is used yielding a considerably lighter, better deck that is stiffer and keeps its pop longer than normal decks.
