Comfortable on all terrains, the Circuit is equipped with the camber/rocker profile AmpTek AutoTurn and is for beginner to intermediate riders who are looking for a directional board, easy to access, flexible and tolerant to accompany them, for the former, in their discovery of snowboarding and, for the latter, in the improvement of their technique, whatever the snow conditions. The AmpTek Auto Turn profile corresponds to a combination of rocker, or negative camber, on 80% of the effective edge length and positive camber, on the remaining complement, significantly reducing the risk of flange failure while improving the handling of the board and its ability to fly quickly. The whole allowing to progress more naturally.
