Area with no release issues at all. (Came off once in the chop when I buried a tip)
On way back to lifts I was in a wide tuck going 35-40mph down the runout to the closed Harmony lift. Been doing that same straight tuck for 25 years to avoid walking the flat. This time I started to fall and was first surprised then scared! I couldn't believe I could be falling, and started to stand up to correct and saw my ski fall off! I think when I stood up the binding had already released, but was still with me for a fraction of a second...Whatever...hard tumbling crash, hurt left knee and ankle, spread out over 50', missed beer at Seppos😡.
Total user error...Should not be going that fast on those Dynafit Radicals on hard pack I guess. Snow was flat but had hardened up in the shade and was a little rough.
Now I just hope I heal fast. Consider your setup at speed.

This is a different issue then? Flexing the ski too much can release them? I have just recently begun to use them at the resort to teach the kids. Will I need something beefier if they advance past the blue runs?I don't ski aggressively too often.

I've skied the Dynafit setup hard in both the Tahoe and Baker backcountry, as well as skied The Fingers and Ah Chute at Squaw on them, and in good (soft/powder) snow conditions they've performed like a trooper. Heck, if you want to see what kind of ski flex the Dynafits can really handle take a look at my survival skiing video of a steep and narrow chute that I navigated off the Elbow at Baker. (Don't judge me, please! :-[ Like I said....I navigated, not skied, that one in survival mode. I'm a near 50 year old east coast skier, so please forgive my lack of stomp-age. )

I just don't think the Dynafits respond well to a hard, icy surface under foot. There's nothing in the toe to provide cushion or absorb the shock that an icy surface can transfer through the ski. I love the Dynafit setup but it has its limitations, and isn't a great choice for less than ideal inbounds conditions. Not surprising, because that's not what it was made for!
My Whiteface pre-release was similar to yours. Skiing powder on Skyward I hit a transition to a hard, wind blown, icy stretch at speed. No hard turn, no bumps, just a smooth transition onto ice. All of a sudden a feeling something isn't right, then I watch my right ski head off on its own. The high speed yard sale that followed could have been a lot worse, thankfully. Cranked the bindings and added a pair of Dynafit leashes after that experience....

Yup. Elastic travel! One of the main selling points (deservedly) for high-end alpine clamps. The feel of pintech is absolute dogshit on firm/mixed compared to a proper downhill binder. Pins inbounds sorta work till you push em.

I've had frighteningly similar pre-release issues, and I don't think it had anything to do with bits of ice or ski flex. Granted, my sample size is small as I only expanded my touring quiver beyond the Barons mid season last year, but on two inbounds days (one at Whiteface and one at Baker) I had very unexpected pre-releases.Â

Loved your terrain selection! No matter how old we get there is still an idiot inside who comes out every so often. Obviously they did deal with flex😜

Which all comes nicely back to my original comment -'stay safe out there. There are a great
Many ways these bindings can underperform an alpine setup.
Thanks all, I seem to have just a minor strain. Now the left knee hurts like the right one...Might balance me out better.😉⛷

But remember flexing that influences heel pin retention only occurs on the rebound (bowed with tips and tails lower than the heel) not on the decambering (or with tips and tails higher than the foot as that compresses the heel of the binding against the heel of the boot); rebound is magnified at high speeds and on hard surfaces. Of course "minding the gap" setting the gap between heel of boot and binding heel piece is a major requirement of effective use of tech bindings without spring-loaded mobile heels.
