All info du trenger om Dynafit-bindinger finner du på www.wildsnow.com. Her er et utdrag ang fjær:
"The TLT and Tri-Step bindings have no springs built into the binding to pull the ski tail up to the boot while in climbing mode. I know that other AT randonnee bindings have a spring that pulls the ski tail up while you're sidestepping or kick turning. Is this a problem when using the Dynafit?
This is known as a "return spring," and lack thereof is not a problem. Because of the pivot position and light weight of the Dynafit binding, kick turns are just as easy as those with a return spring pulling your ski tail up, and the uphill kick turn known as a "snap turn" might actually be easier without a return spring. Side stepping without a return spring is sometimes a bit more awkward, since it's difficult to move the ski up parallel to the sole of your boot (the tail drops). With practice you learn to give your foot a sort of flick while side stepping, so that the ski tail jumps up to where you want it. For long sessions of side stepping, you can always latch down your heels (frequently the best thing to do with any AT binding if you're facing a long session of side stepping). I've come to prefer AT bindings without return springs (probably because I'm so used to the Dynafit), and I usually remove them from bindings such as the Diamir."
