Thread: Dynafit trouble

I lost a ski yesterday in the middle of a turn and ended up sliding head first down Spaulding. I was able to self arrest (whippet) and slow myself down some before I hit the rocks. I put my skis back on and and started making slow careful turns to get down and popped a ski again. The same thing happened last week on Drift Peak. Once, maybe even twice, I could understand and would assume it was me not the binding. But thats 3 times in 6 days, and losing a ski in the couloir on Spaulding was not good, thank Ullr it didn't pop off when I dropped of the cornice.

I have Dynafit Comforts on Fischer Kehua's, both with well over 100 days on them, DIN is maxed. I am also 6'5" and 215lbs (so about 250 lbs w/gear). Is it possible I have just worn these bindings out? Am I too big to ski steep terrain on Comforts? Have the skis gotten too noodly and started to negative arch on jump turns? Do I just suck?

Yesterday kind of freaked me out a little. I bet if I sent the binding in to Salewa they would replace them, but right now I don't want another pair until I know what happened yesterday. Would it make sense to try and find someone here in CO who could bench test them? Would Salewa do that if I sent them in and tell me what was wrong?

I'm looking for suggestions here. I love my Dynafits but right now I don't trust them, and I have to trust them for bc. My partner is insisting I get high DIN AT bindings, it was a close call yesterday.

Suggestions on finding the root cause here would be greatly appreciated.

Are you sure that the gap behind your heel is set correctly?

With 100 days, you should know this, but check for ice, dirt, or other debrie in you toe sockets, heel sockets, and under your toe wings. In the spring/summer, I get dirt in there if I hike on dry land that I remove with a small gerber knife before I click in.

Also, Dynafit is coming out with a higher din binding next year.

adjustments set correctly?

heel pins tight? I had the plastic piece that holds the heel pin straight shatter on me once, the heel pin was wobbly and would pop the boot right out.

Dude you are a monster. Get some real bindings.

Trainwreck,

Not enough info on your post for one to make a meaningful diagnosis. Check your boot toe fixtures/dimples. There's some history of some Scarpa dimples deforming and causing releases. There's a thread on this issue somewhere in TT. Good luck.

I would suggest that you fully lock your toe piece before every run, and then unlock it. Locking the toe piece squeezes the pins into the toe sockets and fully sets them.. Often time a little snow or dirt will keep them from fully setting.

This is what I do every time I ckick into Dynafits prior to skiing: Step in with heel in tour mode, Lock Toe, Pivot your boot forward and back several times (dynafit pins have little cutters on them), put toe back in ski mode, rotate heel and step into heel, and rip.

I also check the heel/boot spacing with the little plastic shim every time I tune the sticks.

I just checked and its 6mm on both, which jives with what I found on wildsnow.com. (I dont have the red spacer).

Yeah I'm sorry its pretty sparse info, just looking for any input I can get.

The boots and bindings look fine upon inspection, we are looking at the possibility of the ski negative arching. They weren't exactly stiff to begin with and they are kinda noodly now.
