From my earlier post on Feb 12 at 3:33
|Alright we have two things here. Moving foward to stay over the sweet spot and leveraging the fronts of the boots. The disagreements on tongue pressure sent bells and whistles off in my head because I have been having some problems switching from telemark to downhill.
I went out the hill today to play with the sweet spot and being forward. My telemark boots are considerably softer than my downhill boots but have similar forward lean.
|I am going to remount the bindings on my tele gear to balance over the sweet spot better. Then mount my alpine bindings in a similar fassion and buy softer flexing alpine boots to more closely match the flex of my telemark boots. I hope this evens out the differences that are currently difficult to compensate for between my tele gear on alpine gear.
As far as the racers are concerned, I have to wonder if they have their binding mounted towards the tail of the skis for speed but need a big movement to what appears to be leveraging the fronts of the skis to get the tips to seek the fall line. Maybe it isn't really leverage but moving the CM forward over the front part of the sweet spot. More work but more speed.
Over the weekend I removed the binding on my tele skis and remounted the bindings 4cm further forward of the previously recomended mounting position.
In further tinkering I realized that the forward lean on my boots was set near the maximum range of my ankles in order to allow me to get as far forward as possible to engage the ski tips. I reasoned that with the forward binding movement I could reduce the forward lean to as little as possible. The forward lean was in the second position of three possible. This brought me more upright and allowed more ankle range of motion.
The third thing that I did was adjust my footbed to move the bend point compeletly behind the tarsal heads. This felt better with the more upright cuff.
I took them out on the hill this morning and the results were astounding. No more necessary big forward movement to egage the tips at turn initiation and correction of a few other problems I was fighting.
On my turn inititations, I was apparently bottoming out on my ankle flex and as a result, narrowing up my stance and moving my hip to invert the inside ski. Freeing up the ankle allows a forward diagonal move that begins with tipping and flexing the new inside ankle. Whala, my feet are appart again and I don't feel stuck on the inside edge without the hip movement.
I thought these skis were sweet before now they are fantastic. The sweet spot is also bigger.
How can a person who knows as much as I do about equipment blindly walk into and equipment trap and try frustratingly to correct technique when the correction is in the gear. It just snuck up on me and crept in. This thread is what sent the bells and whistles off.
This whole thing gets right back to Si's comments and what Bob and Weems are discussing. It sure seems reasonable to me that the racers mount the binding further back for speed and use the big forward move to get over the sweet spot to inititate the turn. They are not forward in relation to the balance of the ski but appear so. They are not leveraging as Bob suggests but need the big forward move to get forward enough to engage the shovels. Big ankle range of motion means having the ability to mount the binding location back and still engage the tips. When I look at the racers, I see big ankle flex way beyond my capability.
I think I proved this by eliminating the need for that big forward movement by moving the bindings forward. If I had good ankle flex, the binding placement forward would not be necessary because I could still get the CM up front. I don't have much range of motion and sadly as a result of my experiments, must except the fact that I will not get much lower and flexed in my turns. I ain't never gonna look like them racers. My guess is yah don't get to world cup without rubber ankles.
The real story here is that skiers with limited ankle range of motion can probably do themselves big justice by moving the binding placment considerably forward of recomended and vis versa if you have to much ankle range. Until today, I thought the ankle thing could be taken care of in the boots but I now know that binding location can make a huge difference for people with limited range of motion. Without this thread I may never have stumbled onto that.
Incidently, I tried to get into the position that I see these racers in with the inside knee tucked up and the hips down. I can't come close, even sitting on a little stool to allow the hips to get into the right position above the ground. No amount of contortion can get me close. I just don't have the flexibility.[ February 16, 2004, 03:21 PM: Message edited by: Pierre ]
