  1. Thread diversion: Having made that same discovery quite a while ago my next step was to move the perception point for edge pressure control down to the soles of my feet. (From the longer "Old dog..." thread on technique progression) Sensei Beckmann seemed to approve. The move freed up my knees to better act as a suspension system. The following February (2019) on a trip to Aspen my NASTAR handicaps went to Platinum. Have a great winter 20/21!!
  2. UPZ boot toe fits the F2 step in front bail better than the Bomber step in front bail, so that the load on the boot toe is better spread. Intec setups have inherently less lateral flex than a bail binding. If you want lots of lateral flex and a step in then you want the Bomber Sidewinder variant. All fore and aft flex in bail and stepin binding types really comes from boot shell, tongue and spring system. Manufacturers will usually state if their step in heel is Intec compatible. If it looks like an Intec it probably is. No binding is unbreakable. Even Bombers can fail from meta
  3. @Alexey Thanks, the article translates quite intelligibly with Google translate. My only problem understanding it was the weakness of my math. But it made more sense around the motion of the front part of the ski and the importance of edge penetration control than I've come across in my past reading on this topic.
  4. So, taking the graph as shown, if I can get my board up to 90 degrees on edge I should be able to see my own backside ahead of me. (turn radius =0) Rather, up at 90 degrees the SCR is making relatively little contribution to the curve the board edge follows through the snow surface. The carve curve is now determined by the flex of the board along its' length. The true radius caculation graph is correct in that it shows the radius of the curve formed when all of the board edge is on the same plane when the board is tilted on edge. Trouble is that a carving snowboard penetrates the sno
  5. In GS skiing the minimum SCR is made longer than the athletes might prefer judging by the quotes from athletes when FIS set the minimum. That would make carving tight enough turns harder and more tail sideslipping required to get the necessary entry angle to the next gate. But watch most World Cup / Olympic level GS snowboarders and you'll see a lot of tail sideslipping or even aerial transitions to set the approach to the next gate. As far as I know, there is no set minimum SCR for GS boards at that level of competition. If that is correct then racers have SCR choices but prefer to ride
  6. Everyone who chooses to ride a carving snowboard sacrifices being fashionable for supreme function.
  7. @davekempmeister is also correct , and I have had to do exactly what he describes to release my boot when my rear cable failed during a Summit Expression Session in Aspen a few years ago. I was able to get back to my spares pack, change out the cable and be back riding within about 45 minutes. Rear boot cables generally get pulled a lot more than the front and suffer more wear as a result.
  8. Get yourself a spare cable and keep it close when you ride. Make sure you know how to replace the cable before you need to do it on the hill. Watch out for ice accumulation under your boot heel preventing the pins from engaging properly when you step in. If it feels at all odd, stop and check and prevent a release in your first proper turn. Make sure you keep your weight down as you pull the handle to retract the pins, then lift your heel up. Trying to do both simultaneously will be hard work and cause wear on the cable. Love Intecs, in particular for the lateral stiffness which
  9. https://www.cdc.gov/mmwr/volumes/69/wr/mm6942e2.htm CDC report on USA excess deaths for 2020 so far. Approx. 300,000 excess deaths for 2020 so far. Scroll down the page to see the graphs.
  10. Interesting research from a reputable institution, but a long way to go till this basic science cell manipulation technique in a lab setting becomes a viable and safe treatment for osteoarthritis in humans. Thanks for posting. It is cool science.
  11. Reduced up lift capacity makes for longer waits. But it also means fewer people trying to go downhill at the same time, more space for carving!! That was my experience this NZ winter with social distancing on our chairlifts.
  12. Coming from soft boots you are more likely to prefer binding angles that will probably benefit from some inward canting of your bindings or boot cuffs. You're a climate scientist. You should have no problem getting your head around the ideas about how your body proportions and binding angles interact with tilting your bindings along either axis. Search YouTube for "binding angle secant curve" to get a primer in how this all links together. Then try binding angles you prefer and use your new understanding to make reasoned adjustments to your setup. Carpet carve as Corey, (who is very knowl
  13. What brand ski boots did you fit? Be prepared to do the adjustments you may have used with your ski boots to get comfort, good heel hold down, and toe wiggle room. Deeluxe has a different combo of heel and forefoot width to the UPZs I ride which have a relatively narrow heel, wider forefoot. But Sean may not be able to sell you UPZs.
