By looking at how and where a board flexes we have developed and patented the Rocker Stiffening System (RSS) to increase rigidity by up to 40%. It works by inserting stiffening battens along the rails of the board. The battens then work against the downward force of the rider to produce a stiffer board by preventing flex, similar to how a stringer works on a hard board. The stiffening battens are removable for easy board rolling and can be stored in the carry bag for transportation to and from the water.

This video shows you how to fit the RSS battens into your board.
