Feed your need for speed on the uphill, then feed it again after a quick transition to ski mode. The G3 Onyx AT Binding allows smooth power transition from leg to boot to ski for superb control and feel. Revamped and ready to bust out of its cage onto the slopes, the Onyx is lighter, less likely to ditch out unnecessarily, and a generous DIN range lets you find your optimal setting.

  • Ability to go from tour mode to ski mode without removing boot from binding
  • Mounting plate system means toe and heel attach to separate mounting plates, so you get plenty of adjustment and can maintain boot-center on the ski
  • Multiple heel options are reliable and super-easy to engage with pole-basket
  • High-strength, forged aluminum components for a stiff, rigid connection between boot and binding as well as binding and ski
  • Releasable with both forward-falling and lateral-twist settings
  • Serviceable binding for fixing in the field or getting parts replaced (serviceable with #1 Phillips, #3 posidrive, and torques T10, not included)

So far so good

  • Familiarity: I've used it several times

Bought these to pair with Voile vector BC (fish scale) Based on the fact that you could switch back and forth between hike and ski mode while toes still attached. Works great with that setup. Drilled inserts into and older set of BD Havocs that were barley used before. They drive those skis well. Not a shred of evidence that they are anything but secure and.stable on the descent. Have heard some complain about getting into them, but have not found them to be difficult. Have had them both in icy crud and virgin MT pow and again very stable and secure.


  • Familiarity: I've put it through the wringer

These bindings ski and tour very well, and I use them for everything from resort moguls to backcountry pow, no complaints and no prereleases.

The good:

- I like that all the moving parts are big chunky pieces of plastic; makes it super easy to manipulate with your poles, zero fiddling required.

- I like that you can switch between ski and tour without getting out of the binding. It's nice if you have long rolling approaches and make use of kick wax, and can save you some time and transitions.

- Lots of adjustability.

The meh:

- Initially was really stoked on the swap plate system, but idk if it really makes sense for $70. The range of adjustment is huge but.... meh. Much more expensive than a set of threaded inserts, but not that much better (for me).

The bad:

- These. Brakes. Blow. The mechanism that engages/disengages them relies on flexy plastic parts. Worked fine at first, but after a few ski swaps using the plates one brake never deploys anymore and the other only most of the time. I'm switching back to the heel cowlings and leashes.

- About 1lb heavier than Dynafit Speeds (w/o brakes)

Bottom line is that I got these because they were cool and different, and seemed less intimidating than Dynafits for my first tech binding experience. They're a MASSIVE step up from any plate-style AT binding and I'd definitely never go back in that direction. But at the same time, when you can (usually) get some Dynafits for the same price or less I don't think these offer much more for the extra weight. If I could do it again I'd get Speeds, Vipecs, or IONs for sure. That said, they've served me well through all conditions, resort and backcountry. Can't fault their performance.

Reliable, Cool Features, Junky Brakes

  • Familiarity: I've put it through the wringer

I now have had more than 100 days out on this binding either in the backcountry or on the lifts and, with the exception of the brakes, haven't had a single issue with the binding. No pre-release, no unusual wear, no nothing except for solid performance all the way around. The bindings are super trustworthy and have never given me a second of hesitation on challenging lines.

The only weakness this binding has is the brake system. The brakes are really weak and you need to be aware that your brakes often won't always deploy when stepping out of the binding. Lastly, the binding requires that you depress the toe and maintain lite pressure on it in order to step in to the binding. If you find yourself getting into your skis on steep terrain regularly this could be a bit challenging. At the same time, I've never had an actual issue with this and it is more of a in-theory problem rather than something I've encountered in the BC.

Also, G3s customer service is awesome. I lost a ski in a crash last year and the folks at G3 hooked me up with a single binding at a cost well below retail. They rock.

At the same time, the binding skis really well and the swap-able plates are awesome. If your intent is to have one pair of skis for the backcountry, then I'd look probably go Dynafit. My preference is to have two pairs of skis; one ski is a early season rock ski (Volkl Mantra) and than a DPS Wailer 99 for everything else. With one binding and one additional set of plates this two ski quiver has been economical and performed exceptionally well.

Pretty much agree with JayBo's take, though I"ve had better luck with the brakes. In fact, in my experience, the brakes are one of the strong suits of the binding! A little prone to icing up and not deploying in certain conditions, but my Dynafit Vertical Sts have the same problem. And while the Onyx does weigh more than the Dynafits, the boot retention and downhill performance are noticeably better; to the point where there are very few situations that I'd reach for the Dynafit over the Onyx.

Don't get me wrong, Dynafit's are great, and I've logged many days on them. But the Onyx is a really sweet binding in its own right. And I love the plate system...

Durable Onyx Gem

  • Familiarity: I've put it through the wringer

Went touring with a good pal o mine last week in Tahoe before the resorts opened up. Here's what he had to report on the Onyx binding:

" I know isn't quite a Dynafit, I have put probably close to 100,000' vert on it with almost no issue. I like the way they ski, AND whats really cool is they mount on plates so I have two pairs of skis with plates mounted on them, and I can move the bindings back and forth depending on the conditions/type of skiing I'm looking at for that day. They are also quite affordable as tech bindings go."

He's stoked.

So is his dog.

Bolt pattern on G3 Onyx binding?

  • Familiarity: I've put it through the wringer

In other reviews I kept reading about the narrow bolt pattern in the toe of the binding. Has G3 updated this?

Have we seen installation changes from 2011 to 2013?

To better explain what I mean, I have copied that review:

Although the binding is good for DIN 12, their bolt pattern is far too narrow which puts tremendous torque on the toe bolts. Both of us ripped our bindings out of our skis within 1 week, destroying our new skis.

Rock solid

  • Familiarity: I've put it through the wringer

After looking into different tech bindings I finally went with these. And couldn't be happier. They are amazing on the uphill. I love the pole activated heel risers. And when it comes time to ski... These babies are super solid. I'm 6'6" and 180 pounds and I ski hard. I have snapped skis and broken bindings. Two seasons and these bindings are still like new. These things can drive big skis, I'm talking 191cm long 120mm underfoot, no problem. Maching through chunder and never pre-released. They are a bit heavy, but totally worth it for the confidence they inspire when you're skiing or hucking. I am way stoked on these bindings. And I reccomend them to everyone.

just go with dynafit

    I need to be honest, just go with dynafit. I had these, 2 pairs of onyx and both pairs failed. the design seems to be well thought out and DOES switch between tour and ski, which is a great feature for crossing over flats and kicking your way out of places but other than that, they just have too many moving parts to be viable for any real longterm BC use. I never poped out nor did i insta tele but i bought a pair of radical speeds and the radical ft and and could not be happier that I made the move to dynafits.

    Have to agree on this. I have put a lot of miles on these bindings and have had times that I wanted to throw my skis in a wood chipper (especially the brakes, for God's sake, don't buy the brakes). The toe piece not staying open allowing easy step in is a pain. The tour/DH mode switch lever being tripped accidentally if you get a little sloppy on landings has lead to a few really bad falls. The toe will release very easily even when locked in tour.

    One good thing - I'm a bigger and powerful skier and they feel solid cranked up to 11 and railing down couloirs.

    These things are a recipe for mental anguish.


      A lot of people trash these bindings for being made out of plastic. Well, my AT rig fell off the top of my car at 50 mph, and the bindings weren't even scratched. They are also awesome on the downhill, and even though they weigh more than other tech bindings you don't notice because you don't lift your skis when you tour.

      Unanswered Question

      Those the plates have somehow a life time of interchanging them on each skis? I mean if the bolt get used a bit more each time for example and they become more fragile?

      Do these come with heel cowlings and leashes or just brakes?

      Anyone here know if it would be advisable or even possible to mount these on Volkl V werks Katanas? I have Barons now but I am looking for something that skis almost as well, but is much lighter on the uphill. I understand the use of bindings other than Marker will void the warranty (which is another issue I won't rant about here), but wondering more if the mounting block will work with the G3's.

      I also worry that they might not stand up to my abuse. I am only 190 lbs but I tend to break stuff and I am not shy to TRY to go big when the conditions are right. Not worried about pre-release, but I am worried about the bindings ripping the top sheet off my favourite skis, especially considering this will be the third set of bindings mounted on them. It already sounds like a bad idea.

      Best Answer

      You have to mount a binding on there that is wide enough or heli-coil those suckers in there. I DEFINITELY wouldnt mount them a third time, and I DEFINITELY wouldnt mount an Onyx on there. At least get the Ion, the Onyx will blow up regardless of what ski you put them on.

      I read something in a WildSnow preview...

      I read something in a WildSnow preview that the G3 Onyx had a base 'plate' mounting system for swapping with different skis? Is this still the case? If so, is the base plate purchased separately?

      Best Answer

      Yes and Yes. The base plates are sold separately and retail for about $70. You get the pair that comes with the binding and then will need to purchase a pair for each other pair of skis you want to mount the binding on. I have one binding that I swap between multiple skis depending on conditions. It takes about 5 minutes to make the swap and is fairly straightforward.

      What information on the binding will identify the "model year".

      HI Barb, the only way to know for sure is to contact G3 and give them the serial number on your binding. S/N can be found underneath the Toe and heel pieces if you take them off of the mounting plates. There are some indiators if you do not own a binding yet. The Onyx was initally launched with a whitish/grey heel lifters which later turned to Black/Grey as they are now. Other changes have been the addition of the rubberized section of the toe that you depress with your pole (11/12) as well as the change of color to the mode change lever on your heel from black to red.

      Are these made with just aluminum or is there plastic components in the binding? Worried about longevity do to torsional stress and uv degradation over time.

      Best Answer

      Planning to hit the tanning salon with your skis on?

      The bindings are made of aluminum and fiber-reinforced plastic. Most FRP is UV-stabilized. Given the fact that most bindings are retired not because the plastic is dead, but because the springs have worn out, I really don't think you have anything to worry about.

      Have the heel riser and other durability issues with the heel been addressed?
      What is the weight savings of the new model over the old?
      Has the ski brake been fixed and does it have an AFD?

      I really like the idea of this binding and it's adjustability for multiple users, especially compared to the 12.5mm range of the new Dynafit Radicals.

      Best Answer

      Heel riser issue was fixed. The pins on which the risers rotate now have heads on them.
      No weight savings between winter 10/11 and winter 11/12 (no penalty either).
      Brake was fixed in winter 2010. Brake does not have a sliding AFD.
      G3 Onyx has 33mm of adjustment. But the Dynafit Radical actually has 25mm of adjustment (12.5mm each direction).

      How would these do as an 80/20 inbounds/...

      How would these do as an 80/20 inbounds/backcountry binding? There will be moguls and hardpack. I'm a pretty good skier, but I can't charge hard all the time. I'd be mounting them on '11 Moment Rubies and I'm 6' and about 185. I really don't like the Duke's release mechanism (or lack thereof). Montana Snowbowl in Missoula can get just about every possible snow condition in 2500'

      Tech system bindings (G3, Dynafit, etc.) all have great DH performance as you are truly locked into the ski. The one drawback for hardpack and bumps is that they have zero elasticity (the ability of the boot to move off center in the binding and then come back without releasing). That said, I would rather have the better skiing and lighter weight of these bindings than any other backcountry system. They ski better and tour better.

      Dukes have a much safer and more reliable release/retention mechanism than any tech binding. That's the whole point of hiking around with more than three times the weight of a tech binding. I'm not saying you shouldn't switch to a tech binding, just that your Dukes are a lot safer and more reliable than anything else out there.

      They are OK as an inbound binding. Somewhat less elasticity than dukes or freerides, but they also give a way more rigid ski connection.

      These bindings were designed with retention in mind and with the expection of the Dynafit Beast are the most inbounds capable tech binding.
