Description

The Onyx is ready. Are you?

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)

Best Binding

Light weight, Love this binding, easy to change from one method of skiing to another without removing the boots.

Reliable, Cool Features, Junky Brakes

  • Familiarity: I've put it through the wringer

I now have had more than 50 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.

That being said, I do think there are a few things worth considering in shopping for a binding. First, G3 has announced their new ion binding so it MAY become harder to find parts or additional plates for the onyx depending on what G3 has in mind. The brake system is really weak and you need to be aware that your brakes 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, 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.

Responded on

Peter,

Just came from a Backcountry.com G3 clinic and got the latest. It is still the same bolt pattern and one that many other manufacturers are using including Dynafit and Marker. They haven't seen a problem with them ripping out unless you've not glued the screws or possibly really large sized skiers.

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 Responded on

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.

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.

Responded on

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.

Anyone know if these have the same/similar...

Anyone know if these have the same/similar ramp angle to Dynafits?

Responded on

The Onyx is 26mm stack at the toe and 30mm at the heel for a 4mm ramp. Dynafits are 20mm toe stack and 30mm heel for a 10mm ramp.

Bombproof

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.

What information on the binding will...

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

Responded on

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 Responded on

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...

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 Responded on

Jonathan,
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'

Responded on

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.

Responded on

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.

Responded on

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.
