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.

Questions & Reviews
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
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.
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
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 email@example.com 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.
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.
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
At the Bottom line column in the comparison chart, Dynafit ST Rotation 10 bindings are "Knee-friendly backcountry skiing". What does Knee-friendly" means?
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.
