  1. Hard to tell what the grip system looks like.  If its positive grip or if it uses those clips that are wound into the cable.

     

    But looking at this is seems like the part that failed was the retainer that keeps the chair on the pin that it pivots on.  The two bolts they are talking about could be a retaining cap.  If the bolts were over torqued and plasticized then they could have sheared of due to a shock or just vibration.  Second photo is a retaining system that uses a cotter pin...

  2. In GS, It's not so much a matter of needing to shed speed, it's that the rules changed to require larger sidecuts, while the course setting parameters remain the same. Athletes then innovate to 'make the line' without undue loss of energy.

     

    In snowboarding, its a matter of technique lagging technology.

     

     

     

    Not direct, but a gliding ski is equivalent to a running engine, with sidecut to HP, and rebound to torque.

    Theoretical 'stivot' around :47. 'Float' the chassis sideways with wheels rolling, counter steer/establish lean angle, find the line, then roll the throttle on.  More or less comparable to what Hirscher is up to.

    The bottom line on snow is not excavating any more of the working surface than necessary, which requires a very light touch on re-entry, such that the skis glide, rather than 'bounce' into their respective arcs.    

     

     

     

    The respective platforms may look different, but their essential function is the same.

    You'll notice that Ligety, Shiffrin, Hirscher, et al, are all very effective with their inside ski. A snowboard is an 'inside', rather than an 'outside', ski. Ergo, assuming comparable pressure control, the rider should be able to replicate, to greater or lesser extent, the technique employed by the top level skiers, at least in GS.

    The future of snowboard technique can be found in WC GS. The future of WC GS can be found in motorcycle road racing, and WRC Rallye. The difficulty for snowboard racers is making the leap from the established paradigm (resembling ski technique of the late 80's) into the present.

    I'm talking snowboard.  I'm aware of the GS regs for skiing.  These don't exist for snowboards AFAIK.

  3. If you never had to slow down to make the next corner, that would remove some of the excitement/rush of doing and watching!  

     

    Disclaimer: I'm a non-racer and frankly find snowboard racing pretty boring on TV.  I can watch ski racing for hours with the varied courses/speeds/obstacles.  

    Depends on where you get your excitement...

  4. Looking at this from the car racing side, there are turns where you just can't make it at your current speed.  So, you use the brake to slow to a speed where you can just barely make it and still be on the racing line for the next turn.  Do this early so you can have your peak speed at corner exit so you're faster to the next turn/gate.  Slowing down sucks, but lining up the 2nd and 3rd gates after that pays huge dividends in something like autocross where there aren't long straights between corners.  

    This is what I was getting at.  Is there a reason courses are being set that allow these speeds to be reached, where shedding speed is required? Vs. setting a course that has more cross-hill movement.

  5. Curious as to others opinions on the amount of stivoting seen in todays racing.  I.e. the sliding of the board on gate approach before locking onto the edge.

     

    It's done is skiing a lot, if there is an alpine specific term I have not heard it.

  6. Here's some more pictures. No, just plain sliders.  The plate attaches to the thick slider which itself is attached to the thin slider.  There's a "rail" that allows the thick slider to move along the thin slider.  Notice that the thin slider is thicker on one end (towards the nose)

    Interesting.  Do they provide replacement sliders?  Seems like it would be a pretty cheap part made on CNC.  

  7. Glad to hear you had good results.  I find the biggest hurdle for most people is committing to the turn, it can be a little scary leaning all the way over and hoping the edge holds.

     

    Like you say toeside is a little more tricky.  When I am freeriding or racing I always take my heelside hand and reach toward my front boot/heelside edge.  This must be done while bending your knees, if you bend your hips to make the reach you'll load your nose and bad things can happen.  By reaching toward the front boot slightly you will put some light pressure on the nose, however it will be balanced out by the fact that your crouch is forcing the entire edge into the snow.

     

    This can be progressively done down the hill on a low piste trail, start slow and increase aggressiveness as you make your way down the hill.  Once you progress (and ride try slalom sized board) you will realize that you can carve very aggressively on very low piste trails, as the G forces help to drive you through the turn.  It is a little harder on a steeper trail/longer radius board as you need the speed to keep from falling over.

     

    Hope that makes sense?  I've never tried to explain things in words, only by show.  :cool:

  8. I will not be much help here as I have always been coached in terms of racing but:

     

    Lean forward more, you seem to have quite an arch from the head to your waist.

     

    You mention wanting to get lower to the ground like the extreme carvers do, my number one tip here is that you should never bend at the waist to try and reach the ground (on toeside turns), this will do all sorts of bad things to your form.

     

    Toeside is a bit harder but heelside isn't too bad.  Try initiating your heelside turn and reaching toward your toeside edge.  This will drive your butt down and the heelside edge into the snow.  It may take some commitment and you might skid out the first couple of times.  Once you get the feeling right you can manipulate how hard the drive is by how hard you reach.

     

    As others mentioned you might try widening your stance.  Once this is done the last thing I can recommend is to try and overpower the board, it seems as though you are just along for the ride in the video.  Being aggressive goes a long way in terms of turn performance.
