Element brings you "Push Construction" Which features patented air frame chambers that run the length of the board. There are five air chambers that are evenly spaced through the center two veneers. These chambers eliminate a lot of wood through the core and make this the lightest board that element makes. Now add a wide strip of carbon fiber on the top veneer and this gives you added strength and stiffness. These boards are great for getting the most pop and best flick out of your skateboard.
