The Formula is best described with two words: durability and affordability. With this build, Arbor implements the same technology and premium materials you've come to expect from Arbor, in a timeless spoon-nose shape for riders who want an all-terrain board that will continue to perform as riding ability increases. the Formula is available in both Rocker and Camber System technologies. The System Rocker design provides a surfy ride with natural float and cleaner tracking. The System Camber design offers a poppy ride with crisp, fully engaged performance.
