Although the shape may look rather radical, the riding is smooth and easy whatever the surface condition is. Whether in deep and heavy snow or in tracked out daily slope, the "Acceleration Camber" will thoroughly bring the potential of the board in action. The Speedmaster is a masterpiece within the history of Gentemstick and became the go-to board for many of the legendary riders in Alaska and Europe's big mountains.

The idea of traditional camber is to apply the same amount of pressure onto the entire edge of a board to attain smoother, more stable carving and turning.

The camber arches from the center of the board all the way to 3 cm inside of the widest point of a board, both the nose and the tail. To turn, this camber has to be stepped on and the bottom pressed against the surface. This type of camber is effective at a resort, compacted slope or on a flat face. But it has lots of demerit on deep powder, fresh snow, or terrains with three-dimensional features. It is arched against the direction of the board, and the board could get hooked on the snow easily, making the turn less agile.

The GENTEMSTICK’s radical Accel camber eliminates hooking and prevents nosedives in deep powder or fresh snow, while maintaining a natural floatation. It is designed and shaped to perform its best when the rider stands neutrally on top of a board. It is made flat from the widest point of the nose side to about the front foot. The arch begins there and reaches the highest around the back foot, and it ends at the widest point of the tail side. When a rider stands on the board, the arch gets pushed and the area ahead of the front foot barely touches the snow.

This is the position that maximizes the performance of the board, and also the same position that reaches maximum velocity in ski races and other speed competitions. Accel camber has an arch from point A to point B. The board becomes flat as the back foot pressures the board. It rises slightly from the point C to the nose, which effectively reduces snow resistance. There are boards with similar camber designs released from major manufacturers these days. It is important to remember that the nose rocker design becomes very important with this kind of camber system, which has the peak of its arch placed further behind the center of a board. The GENTEMSTICK Accel camber boards are distinctly designed, especially from the point where the camber ends to the widest point of the nose. The key is to reduce resistance.
