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.
Update 2019/20 - The toe lever gets a new paint job!

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?

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.]

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.

I have a ski that is 95mm under foot. Can I use the 90mm break or do I need to go larger?
1/9/2020
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.

I have a ski that is 110mm under foot. Should I use a 105mm or 120mm brake??
10/29/2019
Hi Kena, we'd recommend the 120mm brake given the width of your ski.

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.
6/10/2019
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

I have a pair of Black Diamond Element 175 skis with a waist width of 115. I would like to purchase your Dynafit ST Rotation 10 Bindings. Do I order the 120 brake width or the 135?

My question is similar to one above but I just want to confirm before ordering... my skis are 92 underfoot, would the 90mm brakes work or should I go with the 105s? Thanks!

Hi Lauren, the 90s will suffice!

What are the mounting specs such as the drill bit sizing for the screws?
2/6/2019
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.

At the Bottom line column in the comparison chart, Dynafit ST Rotation 10 bindings are "Knee-friendly backcountry skiing". What does Knee-friendly" means?
7/19/2018
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.

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
12/2/2017
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.

Hi Anthony, get the 105s, they work up to about 110mm-wide skis.

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?

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.

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?
9/17/2017
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!

Do the pin height figures for this one correlate to radical ST, vertical ST, or its figures are unique?
8/26/2017
Hey Stack, thanks again for reaching out! Delta will be identical to the Radical 2.0 binding at 13mm.
