ABSTRACT:
A system for damping and/or stiffening a ski having a damping member and a stiffening member which are engageable and disengageable through the operation of a clutch. The clutch is engaged by a change in a threshold condition, such as a shift in the skier's weight during skiing. Engagement of the clutch engages the clamping member and/or stiffening member. The system maintains the damping member and/or stiffening member in a disengaged condition until the skier commences a turn, engages the damping member and/or the stiffening member during the turn, and disengages the damping member and/or the stiffening member once the turn is completed.
