The Z7 is the first D3 ski to feature ZTM. Zero Tolerance Manufacturing. Designing the perfect ski shape is only half of the slalom ski performance battle. Once the ski mold has been cut
then it is time to establish the rocker and flex targets for the perfect ski. Once rocker and flex parameters are finally identified reproducing the same ski over and over is always the ultimate manufacturing
challenge. During the production of each and every Z7, D3 has reduced the tolerance of all critical design parameters to virtually ZERO. This makes each Z7 we produce the perfect slalom course specimen. No other
manufacturer comes anywhere close to our ski to ski consistency and day in and day out quality. The proof is in the performance.
Modified tail exit radius
- Reduces water tension and drag improving skier speed.
Increased depth of tail concave – Absolutely eliminates tail release or “tail blow” in extreme turn situations.
Increased radius of the bevels from the rear heel to the tail of the ski –Allowing the ski to ride deeper in the water, improving skier stability during the edge change and glide out to the buoy.
Relocated transition from rocker to flat spot - Places the fulcrum point between the skiers front and rear foot putting the skier in complete control of the turns.
Modified concave as it transitions to the outside edge- Improving the glide-out and stabilizing the edge-change, delivering course width without additional skier effort.
Increased radius size of front bottom bevels - Engages the front rocker of the ski to help initiate the turn and allows the skier to progressively build angle approaching the wake.
Ski design legend Denny
Kidder and on-the water design engineer Will Bush have left no stone unturned while teaming up to create the Z7 ST, the ultimate tournament ski. Feel the stability, consistency, width and speed of the all new Z7 ST
for yourself.
Center Mass Load Distribution - The ski is wider under your feet, creating more support and improving overall glide.
Programmed Concave Transition - Creates stability
during the edge change, eliminates pre-mature roll in.
Progressive Radius Rails - A small, flat area where the concave and bottom bevel meet. Improves stability and control.
Compound Radius Bevel Definition - The most complex combination of increasing and decreasing radius bevels ever produced. These compound radius bevels improve the stability of the ski throughout the edge-change
and turn. Delivering the rock-solid feel short line skiers demand.
Inside Radius Side-Cut - Improves turning, eliminates the “all at once” turn.
ZTM (Zero Tolerance Manufacturing)
- Improves individual ski consistency. Ski cloning is now possible.
Three stage rocker - All three zones are designed independently for the largest sweet-spot available.
Symmetrical Turn Design - The tip to tail overall rocker, platform placement (flat spot) and rise over distance is independently controlled and measured to guarantee left and right turn symmetry. Left and right
foot forward skiers will have the best turns available. No smoke and mirrors, the perfect blend of these design parameters will result in a great turning ski on both sides.
