ProView – Dynafit ST Rotation 10

I’ve always thought that the best gear is the gear you think about least because it simply does its job and lets you focus on the activity you’re doing.  If you’re looking for a tech binding that excels in this category, the ST Rotation 10 has you covered.   

Dynafit ST Rotation 10

Product Description: The ST Rotation 10 Ski Touring Binding is the evolution of the Radical ST 2.0 Binding. It offers the largest possible entry comfort with its new, integrated centering system. The pivoting toe piece avoids unintended releases, guaranteeing you TÜV-certified safety. This pin binding offers 22.5mm of flex in the length adjustment in both directions and can be set for a release value ranging from 4-10. A forward pressure of 10mm ensures that the release value remains constant even upon deflection of the skis.

Dynafits on Steeps — Yep!

I live in Vermont so you’ll understand when I describe our snow conditions as varied.  Hardpack, ice, powder, refrozen wind affected moonscape…you name it, we’ve got it.  And so what better place to test the reliability and trustworthiness of a tech style binding?  Having years of experience with past Dynafit products including the Radical 2.0 which preceded the Rotation’s release and I’m happy to report that Dynafit simply made an already awesome binding even better.  Here’s why.  The Radical 2.0’s rotating toe involved a minimal, but undeniable level of quirkiness when transitioning to ski mode.  If your toe wasn’t perfectly straight, slamming your heel into the heel piece wasn’t easy.  And so you’d have to subtly rotate your toe until it looked straight and then try again.  From a design perspective, it certainly left the door open for improvement.  And that’s exactly what Dyanafit did with the new Rotation series.  Now, the toe has a dent (a groove) at the dead center that you can feel as you’re rotating your toe around.  Simply rotate to the notch and slam your heel down.

 

Other than that, the binding remains largely unchanged from the previous Radical 2.0 series, which is a good thing. The heels are reliable, carry a DIN certification, and provide 10mm of forward pressure.  The heel risers deploy easily with the flip of your pole and offer two comfortable and effective riser heights.  In walk mode, the brake catch is effective and keeps the brakes up and out of the way.  I’ve never had an issue with icing in the toe or the heel…and I definitely have had such issues with others bindings.  

But can you ski them at the resort?  Of my average 100 days of skiing a year, most of my time is spent on the skin track and in the backcountry, but I do ski about 30 days a year at resorts.  These bindings have performed flawlessly, at all times, everywhere I’ve taken them.  Now, are they specifically designed to meet the demands of day in and day out resort skiing?  Absolutely not.  If you’re a more dedicated resort skier who likes to throw in a tour every once in a while, you should look at a frame binding or the Kingpin or the Shift.  But, to be clear, the RT10’s can certainly hang with a resort day.

Uphill, downhill, across the hill, and everywhere else, the RT10 blends the best attributes of what tech bindings have to offer

Durability/Construction

Well engineered, clean design resists icing and takes the abuse of hundreds of days of skiing.  

Terrain factors

If there’s anything that gets me nervous about tech bindings its steep, firm, snow in high consequence zones.  The kind that really puts the lateral pressure to a set of bindings.  These bindings have done just fine in that kind of terrain and they’ve gained my trust.  And for every other kind of terrain…well they just rock. 

Friendliness to the Earth

Dynafit prides themselves on partnering with and supporting several environmentally focused organizations.  They also do their part to limit their supply chain and try to keep things as local as they can within the confines of also running a successful business.  It’s fair to say that they’re doing their part to help our planet.
