Vibration Damping . . . What is it ?

construction.gif (10993 bytes)

      Vilbraltion  (vi - bra' shen)   1.a The act of vibrating  b. the condition of being vibrated  2.a the rapid linear motion of a particle or of an elastic solid about a equilibrium position  3.a   A single complete vibrating motion, a quiver.

           Dampling   (dam 'ping ) 1.n The capacity built into a mechanical or electrical device to prevent excessive           correction and the resulting instability or oscillatory conditions 2.a To deaden, restrain, or depress.
 

 

 

What's does Vibration Damping  have to do with skis and skiing ?

Answer: If a ski is continuously making & breaking contact with the snow & ice

it is slipping and releasing, causing the skier to constantly adjust angles & forces to maintain control.

This excessive adjusting requires additional energy both physical and mental. Ski longer and in control with  The CLAW.

Arc-to-Arc Skiing Technique & Therory

Symmetric Side Cut      Claw Skis

The combination of a short radius symmetric side cut plus the patented, extreme damping design of the CLAW gives a unique opportunity for arc-to-arc carved turn skiing. But, your skiing style and movements should be adjusted to best use those new ”tools”. Most of the up and down, fore and aft rotation and subtle edge control required to skid traditional or transitional skis are now superfluous. All of the symmetric CLAWS are best skied with the following guidelines; the goal is to carve most of all your turns and skid into longer or shorter than the carved turn arc only when necessary. Remember, there is only one true carved turn arc (radius) for any given speed and ski side cut radius. Find out what turn the ski wants to carve and evolve your flow down the mountain around this radius.

 Feet Apart: Between five inches (hip width) and twelve inches separation between skis. Combine this with a lower, bent knee strong body position. When turning experiment with the outer ski way out to get maximum edge angle while unloading the inside ski by bringing your upper leg up closer to your chest. If the boots are too close while carving, the inside boot will restrict the freedom and edging of the outside ski. Bring the skis together in powder or in moguls. The weight will be distributed about 70 to 90% on the outside ski for maximum leg strength although you can practice balancing on either ski alone.

 High Edge Angles: In order for the skis (especially the outer ski) to hold and carve, “fall in” with your hip toward the center of the turn. This leaves the skis out to the side and is just the opposite of pushing the skis out to the side to skid and control speed or change direction. This will be disconcerting at first and will not work with traditional skis because the skis will run too straight. The short radius skis, however, will generate substantial centripetal force, which will balance the centrifugal force you develop and keep you from falling inward. Have faith; the skis will come back under you as you move across to the next turn. Very short radius skis like the symmetric CLAWS will immediately start carving a tighter turn than the other shaped or race carver skis on the market.

 Steer with your Hip and Knee: As you move to the inside to edge the skis also move your inside hip forward toward the center of the new turn. This will feel like rotating your hip counter to the turn direction but actually the skis are making the direction change and your hips (as well as knees and shoulders) remain quiet, parallel to each other, and facing down hill. Your boots will also remain in this parallel plane which will result in an inside ski lead (shuffle). This should feel like you are bowing outward towards the outside of the turn and your body will feel quite angular. This position allows you to best resist the strong centripetal forces generated by the carving skis.

 Quick Arc to Arc: Make your high edge angle from one turn to the next quickly while rolling both knees and edging the skis in unison. This is very much like roller blading. If you up-unweight to flatten the skis as was necessary in the old days for a skidded direction change...you will skid...just what you don’t want to do. We’re talking about absolute, pure carving. Many will say that it’s not possible but the racers do it at higher speeds and longer radii. With short radius symmetric CLAWS you can assume exactly the same body position as a world cup racer but at speeds and radii that are appropriate for recreational skiing, tighter GS courses, and slalom.

 Understand the Equipment: A carving ski will carve a turn with a radius about 70% the side cut radius; e.g. a 21 meter “race carver” ski, which is the FIS minimum for GS racing, will try to carve a turn of about 15 meters or 50 feet radius. This is too large and too fast for most recreational situations regardless of skier ability. Even the new short slalom skis on the market today have 16 to 18 meter side cuts which is in the same ball park as the longest radius (185-18.5 meter) symmetric CLAWS. In order to control your speed by carving across the slope, “tree to tree” without having to resort to skidding, you need a ski in the 12 to 15 meter side cut range. For instance the 163-13 meter symmetric CLAW will carve about a 30-foot radius turn. This allows arc-to-arc skiing at 90 degrees across the fall line in a typical 60-foot wide trail. Longer radius skis than about 15-meter side cut require some skidding regardless of the skier’s skill level. Skiers who claim to be “carving” are in reality pivoting (skidding) the first part of the turn to change direction through the fall line and truly carving (“hooking up”) only in the later part of the turn especially on steeper slopes. All short radius skis need to be very flexible to reverse bend into the turn and not over control at the ends. The CLAW¨ damping system combined with the variable spring rate flex cuts allow proper flex without the ski becoming “floppy” and unstable in straight running or at high speeds.

 Skid Only When Necessary: True carving is very efficient. You will immediately feel new precision and speed. Try to control your speed by coming across the hill more than by skidding (side slipping) down the hill. Your tracks should be “pencil-thin” even on ice. Use the same technique and skis for all conditions except deep powder, which requires a specialized wide ski. Keep driving forward with your upper body, knees, and inside hip to keep up with the speed. You no longer have to move your weight rearward at the end of the turn to control skidding. The wide tail and forward boot position of the symmetric CLAWS will give you all the holding power you need assuming the edges are sharp at one degree base bevel. When it is necessary to skid to control speed or change direction in other than the carved turn radius...just release the high edge angle and more traditional movements will suffice. When you want to stop, try not to skid the skis sideways. The short side cut radius and holding power of those skis makes them less easy to skid. Just arc into another turn and carve uphill if necessary.

 Safety Note: As you start carving arc to arc turns across hill without skidding-off your speed. You will quickly become aware that you are skiing across the traditional skier’s down the-hill direction. You will be going the same or higher speed than a skidding skier going straighter down the hill. Be sure and look over your shoulder and check up hill before carving.

 Hands and Poles: As your knees, hips, boots and shoulders stay in a parallel plane; so too should your hands. Traditional, individual pole plants lead to excessive rotation. Instead, keep both hands in front, at a comfortable height, across the hill, and horizontal. Do not drop either hand or let them get behind you. When in doubt move the inside hand forwards and upwards. Your hands will be in ideal position for a double pole plant across the fall line. The double pole plant will bring your upper body forward into a very strong correct position to start the next turn. Use it frequently especially at slower speeds and in difficult terrain. There will be only time for a light touch of the poles but the hand position and down-the-hill movement with the upper body will be the same. When possible, watch the racers as they are leading the way to the most efficient carving skiing. If you stay in a traditional skidding style of skiing, the short radius symmetric CLAWS will not perform as effectively as with a more modern technique.
