Abstract: A structural reinforcement device for a skateboard of the type including a deck having a bottom surface having a first bolt pattern and a truck including a baseplate having a second bolt pattern. The reinforcement device includes a rigid insert having a third bolt pattern aligned with the first and second bolt patterns and disposed between the baseplate and the bottom surface of the deck. The baseplate is characterized by a leading edge, and the rigid insert extends forward of the leading edge to effectively increase the surface area of contact between the baseplate and deck, thereby reducing stress concentrations near the fastening bolts.
