Axcelspring
Torsion suspension system,
This system has been around longer then you would think. We have found a skateboard that is from the 50's that has all the right bone's. Most of the older systems are made with the system on the bottom of the board. In the early days the technology was not there to build it inside the deck. We have found some skateboards that where patented in the 70's that where made and in production.

Description of the modern system.
The Axcelspring™ System is a torsion suspension, spring and absorption system for skateboards. Cars and motorcycles have suspension systems, why can't a skateboard? The Axcelspring™ System is built into the skateboard deck and is designed to alleviate the pressure that skateboarding puts on your hips, knees, ankles and back. This system can lessen the impact of hard landings and prevents repetitive stress injuries common among skaters.
Standard skateboards have cross grains to give pop and snap to the board, but no connection from the front truck to the rear truck. The Axcelspring™ inner core connects the front and back trucks to make them work together. This allows you to turn tighter, faster and harder. It helps you land tricks at harder angles and gives you more pop, snap and spring. The Axcelspring™ System absorbs the noise and friction of rough road conditions such as rocks, dips, bumps and gravel, handicap ramps and bumper to give you a smoother quieter ride. The spring is also designed to help propel you on small hills and sloped streets, giving you perpetual motion. This makes it easier to increase your distance and speed.
Trade mark description,
A skateboard deck formed of laminated layers having increased twisting resistance around its center axis provided by fiber reinforced polymer matrix composite members running along the center axis and cross members extending toward side edges. Side members positioned between pairs of cross members provide additional torque resistance and energy storage for use in springing the board.
