The Grind has been appropriately named because of how well it suits the small, adverse conditions of the WQS, AKA the Grind. The Grind features a large single concave fading into a very pronounced double concave. This is the same board that Gabe Kling used to win the 6 star Yumeya Billabong Pro WQS contest in Tahara, Japan on. The Grind should be ridden 1 inch shorter, 1/4 inch wider and 1/8 inch thicker than your standard shortboard. Recommended for high performance surfing in small waves.
