Dynafit ST Rotation 10 Binding

A more elegant binding for a more civilized age. The ST Rotation is the DIN certification-ready kid on the block, and it’s now one of the best choices for backcountry skiers who want to optimize for knee-protection. It’s a full-featured binding with brakes, multiple risers, and generous adjustability. Dynafit’s latest and greatest also has refinements for smooth operation and easier servicing.

The toe piece sits on a rotation plate introduced with the ST 2.0, which means a consistent heel-release irrespective of the make of your boots or condition of your toe-fittings. However, the Rotation 10 adds a notched centering device which makes stepping into the toe much, much easier. No longer do you need to lock the toe or look down at your heel to check alignment. A quick flip of the beefy toe lever will switch between uphill and downhill modes.

The heel unit is built around Dynafit’s recently added Bayonet Lock, which intelligently connects the baseplate and heel housing of the binding into one robust unit. This results in a stiffer and more secure binding platform, while also improving serviceability. The unit features whopping 10mm of longitudinal elasticity which will soak up bumpy terrain and big landings without hesitation. It also makes the release more consistent throughout the flex of the ski. Paired with the rotating toe piece, this creates a tech binding capable of achieving certification at a low-ish weight. Perfect for the skier who enjoys ripping side-country laps and center-punching remote bowls.

  • Bayonet Lock creates a secure binding platform that is easily disassembled if needed.
  • Rotating toe piece and spring-loaded heel piece will help achieve the elusive TÜV certification.
  • Centering device in the toe makes for much easier step-in versus the ST/FT 2.0 series.
  • A generous +/- 22.5mm of boot sole adjustment so your jealous friends can also take a lap.
  • Aluminum heel internals for corrosion resistance and longevity without a weight penalty.
  • Adjustable forward and lateral release values, from 4-10.

Questions & Reviews

Question from Tim
Hi, do you consider the Rotation 10 safer than the Rotation 10 Lite ? Are both of these significantly safer than a Radical ST or Vertical ST ? Specifically with release in the event of the toe hooking and the risk of spiral fracture etc. My application is for use in resort 50:50
Answer from jbo
Hi Tim, the short answer is yes, on all counts. The Rotation was able to pass the DIN tests with the combination of a rotating toe piece and gapless heel. The old STs have neither of those features, and the Lite has only one of the two.

For a longer answer you can delve into my article on tech binding release. You'll then realize that none of the bindings you mention are optimized for preventing tibia fractures; they do better in the soft tissue (knee) category. For fractures specifically, you'd want to look at lateral toe release binding such as the Shift, Tecton, or TR-1.
Answer from Christopher S
I had a spiral fracture of my Tibia on Dynafit Rotation bindings. Be careful.
Answer from jbo
Hi Christopher, sorry to hear that! My only tibia fracture happened on alpine bindings. Be careful is good advice for skiing in general!
Answer from Bruce A
Ugh - sorry Christopher. Happens every day to someone - even on properly adjusted alpine bindings. My wife (pro level skier) did a big time tib-fib a few years ago on her front side alpine skis.

I have a pair of these on both my K2 Wayback 106 and Salomon MTN Carbon 96 skis, and they're fantastic! They're certainly heavier than other bindings but I wanted a fully featured binding that could be kind to my knees in case of a crash. They work well and handle excellently on the downhill. I have noticed that the spring is thinner than I'd like, but I haven't had any actual concerns about it breaking. I have about 30 days this season on this binding with zero issues and have done some decent travel on them (eg: Camp Muir on Mt. Rainier)

Question from Louis
Hello, I'd appreciate your opinion on whether to go with these or the ST rotation 14s. I am 6'1'', 180lbs, intermediate/advanced with a pair of Zero G 95s. I don't plan on skiing aggressively and will be using these skiis for touring (no resort days). It looks like the 14s weight approx the same and the price is nearly the same. Am I gaining anything with the 14s? Thanks so much.
Answer from jbo
Hi Louis, this comes down to your recommended release value. As long as you're comfortably within the 4-10 range this version will do great. You can use our RV calculator to determine your charted value (I am missing your boot sole length to compute it for you).

Question from Max
Hello, I have a pair of Atomic backland 107. Should I mount a 105mm brake or a 120mm?
Answer from Tristan M
Hi Max,

I would recommend the 105mm brake width. Generally, brakes can be stretched up to an additional 6mm of width, which means that 2mm will be a cinch. If you have further questions, feel free to reach out to!

Question from Penny
I have the new volkl rise beyond 96mm.
I contacted dynafit and they said the rotation 10 in 105mm but I’ve heard the 90mm will fit. Is it better to bend the brakes or have the extra width?
Answer from Ian C
Hi Penny, I would go with the 90mm. You will have to bend them a little but I think that is fine.

Question from laurel
I bought a set of demo skis with these bindings mounted on a rental plate. I am curious about the cost/feasibility of swapping out the rental plate on the toe for the normal toe plate, but I can't seem to find just the piece that goes between the spacer and the toe binding (the part that rotates and attaches the binding to the spacer). I know I might have to drill new holes (by my local shop). Is it worth swapping?
Answer from Will McD
Hi Laurel,
Unfortunately, the Rotation Demo toe can't be installed without the demo plate it comes with, and the rotating toe plate onto which the pins and lever attach is not sold individually so if you wanted to use non-demo toes you would need to buy a new pair of whole Rotation toe pieces.

Question from Nick C
Do previous model years of this binding have different gapping between the pin and the interior portion of the boot? The current model gapping seems to be that this should be a very tight gap (.1mm), but the pins on this heel-piece are not long enough to achieve that.
Answer from jbo
Hi Nick, the gap has not changed since the introduction of the Radical 2.0, now the ST Rotation. The binding in the photo looks properly adjusted; the pins are not meant to go all the way into the plastic of the boot...that extra space lets the boots also work with gapped bindings.
Answer this question:

Question from Nick C
I recently had these bindings mounted and it appears that the heel gap put in place by the ski shop is around 4-6mm. Is this something that will cause issues when skiing? I've seen elsewhere on this site that the heel gap for these bindings is more or less 0.
Answer from jbo
Hi Nick, yes we would expect you to pre-release with that amount of gap on the Rotation. You should be able to adjust the heel closer if it was mounted near the center of the track.
Answer from Nick C
It appears that they not only mounted it far from center but past the stop line as well. Pretty disappointing.

Question from Scythian
Have a comment/question regarding the binding.
Recently I've toured using the setup with these bindings and one of the bindings released in the walk mode for apparently no reason 4 times. It was the same one all times. I was approaching on a very shallow fire road, close to no incline at all, no excessive load (jus me and some 15 lb. backpack). Is this behavior a known issue or is a result of some mistake I've made? I was pretty sure to have locked the toepiece in the walk mode all 4 times.
I have two pairs of skis with these bindings of different vintage. The older works fine, it the new model (19-20, with black lever and Dynafit written on it) that was acting up. A few days before that I skied on this pair on the resort (and eventually skied down on the day when it was acting up) with no problem.
Does anybody thanks any suggestions? Thanks.
Answer from Tim
Hi Scythian,
I am sorry this is happening, that has to be frustrating. Without seeing the binding and boot, it is hard to tell what may be going on. My initial impression is that either the toe of your boot is making contact with the lever when striding or there is possibly something causing the toe lever from staying locked when you are touring..

Would you be able to take a few photos and e-mail them into A photo of the binding locked and un-locked, with and without the boot, would be perfect!

Answer from Scythian
Hi Tim,

I checked the bindings and the bots.
The boots are Scarpa Maestrale RS, and when inserted into the toepiece there is a plenty of room between the boot and the lever.
However, I found out that the lever on one binding does not firmly click into the locked position, it takes just a touch to flip it into skiing mode. The other one seems to lock into the touring position reasonably well.
I think, the problem is that the spring-loaded pin in the lever that retains the lever in the walk position does not fully engage on one of the bindings. I am attaching the close-up photos of the toepieces in the walk mode. The first photo shows the "good toepiece" and the second is the "bad toepiece", you can see that the pins are at different levels. (please let me know if you see both photos, as the reply form show only one). Thanks.
Answer from jbo
Hi Scythian, only one photo came through, but send some to and we can help look into a warranty for you.

Height: 5 ft 2 in
weight: 110 lbs
Ski: atomic bentchetler mini
Skier Type: aggressive

This binding absolutely crushes. I have skied this binding inbounds lots and it had plenty enough power to be able to rip up groomers and take a sustained beating. As for touring, I was pleasantly surprised. I much prefer these brakes compared to other dynafit brakes, the risers are easy to flip with a pole. The rotation in the toe piece is noticeable compared to other dynafit bindings, it does help with pre-release. The guides for the toe make it easy to step into and the lock mode was easy and made a very satisfying clicking noise. My one complaint is that the rotation in the toe piece sometimes made it difficult to clip into the binding. All around this is a great binding.

Question from Brent
Mounting on a pair of Faction Agent 2.0s 96mm waist. Would you go with 90 or 105 brake width?
Answer from Teddy Young
Hey Brent, the 90mm would likely work alright, but you may need to bend it a few millimeters!

Question from Jared
I have a pair of the test version of the rotation 120, is it possible to replace the plate on the toe piece to remove the adjustable demo plate and replace with a standard one?
Answer from eric
Jared- Unfortunately Dynafit does not sell just the toe plate so there would be no way of converting the toe away from the rental track.

Question from Allen D
This are nice bindings, but I am starting to put more trust in lightweight gear (and also not wanting to carry it up the hill). Would the mounting pattern of these be compatible with lighter bindings? Such as the g3 zed and/or BD helio 200?
Answer from Patrick C
Allen D,

Glad to hear these bindings have been working well for you! The drill pattern is unique to the Rotation 10/12 so unfortunately you will need to redrill if you decide to go with a lighter binding on the same ski. If you have questions about specific bindings as a replacement please email us at Hope this helps!

Question from Paul
#1My question is about the brake springs. Is the claim that the springs are thin and pron to breaking? If so is there a field repair?

#2 What size of breaks for Elan Ripsticks 88?

Answer from Jeff
Paul, The springs are not thin, but some people have managed to break them. We assume it is due to snow or ice packed around there. Replacing the base and brakes is the only repair, we stock them.
The 90mm brake width is right for your Ripsticks.

Question from Mark Cunnane
Can you send me instructions on how to set the DIN on the heel piece? Looks like my setting on the large screw has moved and I am not able to find what part of that feature is to align with the DIN marks on the binding body. Somehow this info is hidden from the user. If you don't have info, where could I get it? Thanks
Answer from Julieana
Hey Mark, the edge of the large screw itself should line up to some markings on the housing of the binding. Whatever mark the edge of that screw lines up with is your lateral release setting. The upper arrow is pointing to the vertical release adjustment marks and the bottom arrow is pointing to the lateral release marks that you're looking for.
Answer this question:

thomc (downright abused product)
I’ve pounded mine and not had the brake spring failure. That said it is a thin spring, but not one that has failed on me yet. The binding is a good match with blizzard 108s and as damp a pin binding as I have used. The Hagen aka ATKs pure/core are lighter and more minimal but less damp. The rotation can be a pain if activated inadvertently when stepping in. I’d give em 4 stars for a heavy side country rig which does allow more knee forgiveness and less ski or die reliability
