Ski

They simply refer to the side profile of a ski or snowboard based on its contact with the ground.
The amount of camber or rocker determines the performance of the equipment in different snow conditions. The part which touches the ground when carving a turn is called the effective edge and its length varies depending on the camber or rocker. This article will describe the functionality of both technical features and explain how to use them to your advantage.
Camber is the slight arch between the points where the tip and tail of the ski touch the ground. When a ski or snowboard is placed on a flat surface and the mid-section is raised, it has camber. Without the weight of the skier, equipment with camber has two visible contact points with the snow at the tip and tail. Body weight flattens the ski, creating continuous contact with the snow.
With a cambered ski, the effective edge is longer which gives better stability and edge hold. This is particularly beneficial on hard snow such as groomed pistes, where a good grip makes skiing safer at high speeds.
Camber can be utilised in different ways for different disciplines. For example, the enhanced precision and responsiveness of skis with camber are favoured by racers. On the other hand, the shape gives a springiness and ‘pop’ to freestylers in the park. Until the early 2000s, snowsports equipment only used camber until the concept of rocker came along and changed the game.
Rocker or ‘early rise’ is the curved shape at the tip or tail of a ski and snowboard. The name is based on the shape of a rocking chair which moves back and forward due to the curve of its supporting ‘rockers’. In snowsports, rockers make floating over soft snow easier, since the tips are less likely to dig in.
The curved tips and tails keep the skis above powder and make manoeuvring easier. With weight directly below the rider and less contact with the ground, skis with rocker tend to be responsive and help to move easier through varied terrain.
Rocker is also known as reverse camber, negative camber or alternate camber. For a ski with only rocker and no camber, the effective edge is small which makes carving very difficult. Skis and snowboards can feature a front rocker only with a flat tip or rockers on both ends. Any combination is possible!
So how do you choose which style of ski or snowboard is best? That depends on your level of expertise and the terrain you like to ride. Equipment can feature any level of camber and rocker, or both, so it’s a question of doing the research to find out what features will help you ski your best.
