The Zero Single Skull Deck measures 7.75" x 31.13", 13.88" wheelbase. Medium Concave with Medium Kick. 100% Canadian Maple, Single Deck Press. 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.
