The Unique 3d Glassing process of the board creates the structural integrity of the board as a whole. (With Dynocores the top and bottom of the board is glassed at the same time and contains several space age fibres in combination.) Rather than rely upon the Stringer, outer carbon or balsa rails to give it strength. The most common damage to surfboards is on the rails, if you get a big rail chop on a board that relies on the rail structure for its dynamics.. your boards useful performance life is done..
But not with a Dynocore™ your good to go!
