Definition: Flex refers to the degree of stiffness in a water ski or wakeboard. Flex patterns generally come in soft, medium, or firm. The softer the flex, the tighter the ski will turn, and the more the ski will bend. Wakeboards with softer flex tend to ride better in rough water. The stiffer the flex, the better the ski holds to the water across a wake. Firmer flex on a wakeboard helps the rider maintain proper body position.
