Rocker snowboards exploded onto the market because they're fun to ride. They deliver alternative performance not found in traditional camber designs. Rocker, also known as reverse camber, is created by replacing camber, the lengthwise positive arc of a snowboard, with a reverse shape similar to the profile of a surfboard. By doing so, you eliminate the leverage required to release and reengage a snowboard's traditional outside contact points.
When done right, a "true-rocker" board (no added camber or flat zones) delivers the widest range of alternative performance benefits, including improved turn initiation, seamless performance, and more fluid spins, slides, presses, and butters. Unfortunately, early designs did not provide enough edge hold, so they washed out at speed, in the steeps, and during landings. As a result, designers around the industry have been working to improve the edge performance of their rocker designs. In some cases, this has meant putting camber back into the nose and tail. This "hybrid" design does improve edge control, but it sacrifices some of the benefits of riding true-rocker.
In response, Arbor offers The System to provide riders with an amazing amount of on demand edge hold in a true-rocker design that preserves the full range of performance benefits. They did this by perfecting the true-rocker profile, while building in real edge control through a unique sidecut.
