Arches upwards in the centre of the board with four contact points near the tip and tail. Camber helps you with turn initiation and powering through carves. It is great for popping ollies but a little bit easier to catch an edge. Great for hard charging down the mountain with maximum power and pop.
Reverse Camber / Rocker
The opposite of camber. Curves upwards from the middle of the board to the tip and tail. This makes the board looser, more forgiving and generally more fun to play around with. As the nose is raised you get more float in powder. You might loose a bit of edge hold and pop compared to a cambered board.
Zero / Flat Camber
This keeps your entire effective edge on the snow, spreading your weight across the whole board, giving you a more stable platform and making it harder to catch an edge. This gives you equal pressure distribution for edge hold, reduce drag from the contact points and blends the control and pop of camber with the looser feel of rocker.
Combined / Hybrid Camber
Combines the features of rocker and camber to give you the best of both worlds. Every manufacturer does it differently. Some have rocker in the centre of the board where others put camber there. There are so many different combinations. Please see product description for details.
