Dynafit ST Rotation 10 Binding

Free shipping

A more elegant binding for a more civilized age. The ST Rotation is the new 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 new 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.

Question from Matt
I have an armada tracer 108 and I’m trying to decide if the 105 binding will fit or if I should get the 120. Thanks for the help!
Answer from jbo
Hi Matt, the 105 will be just fine on that ski!

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 help@skimo.co. 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. This photo should help give you a clear idea. 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.

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

Question from josh s
I'm 6'5", 185 riding the 2020 version of this binding and am having some fits with it on the uphill. I've put in five resort days where it performs perfectly. No prerelease issues. I've put in six touring days so far and I'm ready to sell the binding to the highest bidder. When in tour mode, the toe piece swivels too easily. Way too easily, resulting in an average of 5-10 pre-release incidents every two or so hours. I've tightened the screws on the rotating plates with no improvement, and both toe pieces are problematic. What am I missing?
Answer from TSB
Hey Josh, sorry to hear about your binder troubles! The Rotation toe does, in fact, rotate to release the skier during a crash, which may lead to some pre-release when pressuring the toe piece on the skintrack. That said, you shouldn't be seeing quite so many pre-releases, so there might be something else going on. Feel free to reach out to help@skimo.co with some photo/video of what's going on and hopefully we can help you out!

[Update 2/4/20: Also make sure that you are indeed *locking the toe piece* when going into tour mode.]
Answer this question:

Mat (used product regularly)
Avoid these bindings. While they’ll ski fine, the brakes are actuated by a very thin spring that is prone to breaking. I’ve used them on maybe 10 tours and both springs have snapped in the same place. Luckily I had pliers on me or I would’ve been hiking out. You have to replace the entire brake to fix it at $50 per side. Better bindings exist.

Question from Bruce
I have a ski that is 95mm under foot. Can I use the 90mm break or do I need to go larger?
Answer from Jeff
Bruce, these have some wiggle room, will fit to 92-94mm. So that would be ever so slight of a bend to make work. 90mm will be fine.

Question from Kena Krona
I have a ski that is 110mm under foot. Should I use a 105mm or 120mm brake??
Answer from TSB
Hi Kena, we'd recommend the 120mm brake given the width of your ski.

Answer this question:

Question from Scythian
The release values for this binding is 4-10. How does that approximately translates to the DIN release values on the alpine bindings? For example, if use DIN 8 on the alpine setup with boot BSL at 335 mm, will these binding have adequate adjustment range for the touring boot with BSL 317 mm? Thanks.
Answer from Jeff
Scythian, Release values roughly correlate to DIN values, they do use the term DIN, since most Tech bindings are not DIN certified. But the Rotation bindings are DIN certified, so an 8 should be an 8. To correct for the different BSL, use the calculator Binding finder

Question from Isaiah
What are the mounting specs such as the drill bit sizing for the screws?
Answer from Matt P
Hey Isaiah,

It will be a T20 hex wrench for the mounting screws. Drill bit choice is determined by the ski and not the binding.

Question from Yuki
At the Bottom line column in the comparison chart, Dynafit ST Rotation 10 bindings are "Knee-friendly backcountry skiing". What does Knee-friendly" means?
Answer from jbo
Hi Yuki, it means a few things:

1) The bindings are certified to DIN standards for release.
2) Due to the lateral-heel release, they tend to be better for the knees than alpine bindings (which are not designed to protect your knees as we explained in this article).
3) Because the ST Rotation toe is on a rotating plate, the condition of boot fittings has been essentially removed as a release-variable as compared to standard tech toes.
4) With the "gapless" heel on a spring, the release values stay relatively consistent as the ski is flexed.

Added together, these are the most knee-friendly alpine touring binding.

Question from Anthony Addino
Going to purchase a ritation 10.should I go with a 105mm or 120mm brake size on Dynafit Rotation 10? Mounting on a 106mm underfoot Praxis Backcountry ski
Answer from Rebekah S
Hi Anthony,

Go with the 105mm brake. Put the boot in the binding, and then give the brakes a little stretch so they don't touch the sidewalls.
Answer from jbo
Hi Anthony, get the 105s, they work up to about 110mm-wide skis.

Question from John Meyers
Do you know if the drilling is the exam same as the Dynafit Radical ST 2.0's?

Can I easily buy these to swap without re-drilling my ski's?
Answer from jbo
Hi John, yes the Rotation has the exact same hole pattern as the Radical ST and FT 2.0, so a swap will be a straightforward upgrade.
Answer this question:

Question from echo
I want to put the 105s on 100mm skis but I'd like to swap them onto a 115mm skis once in a while. Can the brakes stay locked up on oversized skis?
Answer from jbo
Hi echo, I can't think of a good reason why the brakes couldn't be used in that way. They obviously won't deploy to stop your skis on the bigger ski, but they could be taken along for the ride!
