The angled section leading to the truck mounting can be used as a comfortable foot stopper. This is a freeride style board which is great for sliding and other tricks. Board measures 9.75" x 39.75". The deck is constructed with bamboo top ply and 7-ply's of Maple. This package comes with all parts to assemble your longboard. Includes: Moose Bamboo/Maple 39.75" Drop Down / Drop Through Deck, Havoc 181mm Reverse Kingpin Aluminum Trucks, 68mm 78A Urethane Wheels, Precision Speed Bearings, Hardware, and Clear Griptape. This board arrives un-assembled, which allows for customization and a feeling of accomplishment. Skaters love building their boards! Drop through longboards require advance assembly techniques which include dis-assembling and re-assembling the trucks, we strongly encourage the purchase of a skate tool with this product if you do not already have one.
