The mold determines the camber of a ski. The camber is the skis shape if you looked at facing the sidewall. It determines the skis contact points, how curved up the tip and tail are, and how far the ski sits off the snow. It affects how floaty/poppy/grippy/buttery/snappy the ski will feel.
Camber is generally selected for the terrain type and ski style. The following molds are available for ski building so far!
full symmetric, super poppy, low angle contact area for improved buttering
Adjustable, traditional camber, lengths between 100 -200 cm
