The length of the edge that is effectively in contact with the snow when the board is turning (widest point of the nose to widest point of the tail).
The entire board’s shape, waist and binding insert positions have been shifted from the centre towards the rear of the board. Freestyle boards have minimal setback or none at all (e.g. Squad Line: 0 mm). When the binding position is centered, the nose and tail are of the same length and flex. Freeride boards feature a greater setback (e.g. Selecta 175: 50 mm). More setback enhances board control and powers edge grip at maximum speed. A longer nose also enables more flotation in powder.
By having different binding insert positions, the rider may fine-tune the board’s riding characteristics. Freestylers usually prefer a flatter stance angle of +15° to +21° on the front foot and -3° to -18° on the back foot. Freeriders tend to ride with a +15° to +30° angle on the front foot and a -6° to +10° angle on the back foot.
