The new ZED by G3 is based on the  Lost Binding of Z, that storied apex of design that  only lived in legend -- until the persistence of G3 paid off.

The new ZED 12 ski touring binding by G3 is based on the Lost Binding of Z, that storied apex of design that only lived in legend — until the persistence of G3 paid off.

Ski touring gear archaeologists across the world sifted through dusty parts bins, dug like starving gold prospectors through European industrial dumping grounds, and even excavated through the sifting bone dust of ancient tombs. The search at times appeared endless — ultimately taking nearly half a century.

All quested for the Lost Binding of Z, a fabled amalgam, rumored to have been created by mad engineer Mac Ztrif 50 years ahead of his time. A man who in lieu of modern computerized machining would carve perfect prototype ski binding parts using only a sharp pocket knife and dense knotwood harvested from secret groves in the high Alps of Slovenia.

I thought this was BS, but reliable insider sources tell us G3 had secret agents seeded throughout the world. When a grizzled grave robber excavated what proved to be the Z, the Canadians were as quick on the patent licensing bid as they are on their hockey blades, thus snatching this amazing technology from the hands of their competitors.

Using the Lost Z binding as a point of departure, in little more than 12 months the Vancouver vanguard had a modern version of the ZED 12 ski touring binding they now announce, with plans to retail beginning fall of 2018. What blows my mind is how similar this is to the ION, only I lost count of the subtle improvements. Yeah, it took fifty years, but we have finally reached ZED!

ZED toe is a stripped down and nicely appointed ION, with the same benefits of strong toe wing pressure and geometry that resists accidental release.

ZED 12 toe is a stripped down and nicely appointed ION, with the same benefits.

What’s remarkable about the ZED is how close it is in engineering and appearance to the G3 ION. Indeed, the ZED toe unit is exactly a stripped down ION toe with the same excellent geometry and jaw closing force.

Heel unit is quite different, however, it being significantly lighter, but more, integrating both sideways and upwards release value adjustment into one spring and one adjustment. This is not easy, but clearly the way any lighter weight modern tech binding heel should be configured.

Heel unit is more of a departure,  it's mostly composite material.

As with ION, G3 goes beyond what would be required by TUV certification.

As with ION, G3 goes beyond what would be required by TUV certification in that each and every binding’s release-retention force is measured, _before_ the adjustment scale indicator mark is laser etched. The indicator mark is then placed in position so it matches up to the correct number on the scale for a given release value. Result is clearly one of the most accurately calibrated bindings on the market. (Notice in this photo how the white indicator marks do not match position from binding to binding, that’s because they’re positioned where they belong, not where someone in the art department decided to paint them.

This is one of the G3 calibration stations where they measure actual release values of every single binding. Each binding is barcoded and serial numbered. The laser etcher reads the barcode and thus knows where to

This is one of the G3 calibration stations where they measure actual release values of every single binding. Each binding is barcoded and serial numbered. The laser etcher reads the barcode and thus knows where to “paint” the adjustment indicator mark. Impressive.

True to WildSnow tradition, we did a teardown with the G3 engineers.

This is the heel with top plate and springs removed, showing the tiny metal frame which moves against the grey plastic cam lobes, thus reversing the direction of force so the springs can be used for both vertical and lateral release. If that’s confusing, you are not alone. Takeaway, this is adult mechanical engineering.

Top plate his held down with thin screws into plastic, clearly this could be a weak point as we've seen  countless other times in the industry.

Top plate is held down with thin screws into plastic. Clearly this could be a weak point as we’ve seen countless other times in the industry. G3 engineers showed us results of “can opener” testing during which they rip the top plate off the binding. They assured us that any fatigue of the screws or plastic required an enormous number of test cycles at normal skier weights, and the plastic failed at high force levels before the screws. That’s encouraging but we’ll need to see early adopter consumer testing before we’re entirely convinced.

With top plate removed, upper part is similar to other classic tech bindings.

With top plate removed, upper part is similar to other classic tech bindings. Secret sauce is the cam system as shown in photos above, that allows use of one screw for both vertical and lateral release-retention values adjustment. Note that as with ION, all ZED adjustments are done with pozidrive #3 — brilliant. All mounting screws are pozi stainless, not our favorite (too fragile in our opinion) but they look nice and don’t corrode.

Bonus photo.

Bonus photo. If you were in Chile last summer you might have seen a G3 binding tester with a calculator and load cell riding these $3,000 one-off machined protos. Be glad we have things like injection molding and mass production to bring the price down somewhere in the ecosphere as $449.00 with brakes (see below for brake sizes).

Other thoughts:
The astute consumer of ski touring bindings will no doubt ask “why not just ski an ION?” Several reasons you might go one way or the other on that. Firstly, with ION LT (no brake) you’ll pay a weight penalty of about 114 grams (4 ounces) per foot, which is not insignificant. G3 says the ION might be more suitable for hard charging while ZED is clearly more on the ski touring side of the equation, and thus you get a smidge of durability for the weight price. I’m not entirely convinced that’s a factor for most shoppers, though ION parts such as the toe unit chassis and heel top plate are obviously stronger. A more subtle difference is that ION ingeniously locks out its ski flex compensation while in touring mode, thus preventing possible wear inducing fore/aft movement of the heel unit while in touring mode. Also, as I alluded to elsewhere, due to the virtually zero ramp of the ZED, the heel lifters are probably slightly lower than ION (though we do need to do some measuring on that).

In the end, if ZED proves out, that might simply be proof that ION could be lighter. We shall see. My favorite thing about ION is unlike ZED’s admittedly clever one-screw release value adjustment, you have two independent adjustments and can thus tune release values — something I’ve found quite useful in convincing tech bindings to perform at “chart” release-retention values (and as one commenter mentioned, is useful if you find the brake might be influencing your lateral release resistance). ZED reduces weight and enhances simplicity by combining adjustments into one, but everything comes at a price.

Another thing some of you might care about, ION provides 22 mm boot length adjustment while ZED offers 30. In my view that’s significant. More, you can run ZED with longer demo plate, thus enjoying 62 mm of boot length adjustment for a few grams weight increase per binding. That’s impressive, in fact it’s nothing less than proof that concepts gleaned from the Lost Binding of Z are as timely now as they were when Mac Ztrif whittled that first prototype so long ago.

Conclusion: To say we are excited about this binding is to put it mildly. It appears to be a wonderful contribution, and will no doubt rise to the top choices in the mob of classic tech bindings you’ll be able to choose from beginning fall of 2018. Wildsnow did ski the ZED a few days ago, we’ll report on that in a separate blog post. This is clearly one of the lightest tech binding yet to offer such a robust combination of features, e.g., fully adjustable release to RV 12; flex compensation; wide range boot length adjustment; 3 climbing lift positions including heel flat on ski; optional brake; G3 toe jaw retention features. And, it’s designed and assembled in North America.

Let’s do the numbers:

— “ZED” zero theme continues in the ZED’s ramp angle. Check out our chart. Ramp angle of this binding is virtually zero! That’ll keep some of you happy, while some skiers may want the heel stacked a few millimeters to get the ramp feel they’re used to (me). Bear in mind that binding ramp influences how high the climbing heel lift will feel, in this case we suspect you’re not going to feel stilted to the stratosphere when invoking the high lift, measurement on that is coming.

— Weight 342 grams (pre retail production), single binding no leash no brake.

— Single brake ~86 grams, 85,100,115,130 mm.

— Release values (RV) 5-12.

— Ski flex compensation 10 mm (known as “forward pressure” to those who don’t understand).

— Boot length adjustment range 30 mm, 62 with demo plate at only 25 grams weight increase per binding (pre production weight).

— Mounting screw pattern same as ION, wide, heel 36.5 mm, toe 40 mm.

ZED trivia: We couldn’t help but ponder the symbolism of ZED. Obviously, the word signifies Canada, where it’s a matter of national pride to utter “zed” instead of “zee” in speech. But consider that Z can mean zero, and this coming season G3 will be for the first time in their history make zero telemark bindings — no doubt due in part to the resources they’ve expended on ZED. More, consider that ZED combines both My (vertical) and Mz (lateral) release under one mechanical, thus bringing us one setting for both y and z. Lastly, for 2018 anyway this could be the last word in lightweight yet fully functional tech bindings, and what is last is sometimes first. Z — Zero — G3 ZED.

    Heel post is plastic? I am not afraid of plastic in my binding, but that would give me pause.

  2. Matus January 8th, 2018 7:42 am

    Nice but: Atomic/Salomon is made of metal, is lighter and has better brake.

  3. Frame January 8th, 2018 8:17 am

    That demo plate weight is impressive and must be great for those testing and renting (or going from normal toe shelf to shark nose)

    One small correction. You mention the correct Canadian (commonwealth, English) phonetic pronunciation of the letter Z, but forgot to phonetically write the incorrect US pronunciation of ‘Zee’. In NZ we probably say it Zid… ;o)

  4. Lou Dawson 2 January 8th, 2018 8:37 am

    Thanks Frame, I’ll look at how we write that.

    Matus, unless my recollection is off, it seems nearly all serious breakage of tech bindings over the past twenty years or so has been metal parts? Plastic is fine when engineered correctly and molded up to specifications. So is metal…

    I like the Salomon-Atomic binding as well, but the U-spring release is problematic. ZED, with the G3 toe geometry and fully adjustable 5-12 RV, is very attractive for those reasons. Zero ramp angle will be interesting to many skiers as well.

    Lou

  5. Matus January 8th, 2018 9:12 am

    You are right Lou. Never heard of any problems with G3 plastic parts. But feeling and seeing metal parts just make me feel better 🙂

    Does U spring have some different/worse release pattern comparing to standard two piece spring?

  6. Eric steig January 8th, 2018 9:45 am

    One thing I don’t get about G3 and Dynafit bindings, vs e.g. Atomic or Plum.
    Why 3-position rotation, rather than four?

  7. Lou Dawson 2 January 8th, 2018 10:18 am

    WildSnow tester staff reminds me ZED is clearly one of the top lightest tech bindings to include all of the following:
    – adjustable vertical and lateral release
    – robust fore-aft size adjustment
    – flat-on ski walk mode
    – 3 heel riser positions
    – ski flex compensation
    – optional brake

  8. jbo January 8th, 2018 10:36 am

    Very cool release calibration step before printing! Looks like it is tuned sans brake. It would be sweet to see a published offset range when the brake is equipped. We see similar brake designs without AFDs increase the lateral release and reduce the vertical (by pushing up on the heel). The difference can be significant; you may remember the Dynafit Vertical series had softer lateral springs that shipped with the brake kits to partially account for it. With one adjustment screw on the ZED you wouldn’t be able to fine tune for this lateral/vertical divergence. Curious with the focus on calibration that there is no anti-friction device on the brake.

  9. jbo January 8th, 2018 10:38 am

    Lou – when measured with the brake, the Hagan Core is lighter.

  10. jbo January 8th, 2018 10:49 am

    Oh, and without the brake, the Kreuzspitze EL is lighter by a good margin.

  11. Lou Dawson 2 January 8th, 2018 10:54 am

    Thanks JBO, Raider/Core actually is pretty impressive in what it offers for the weight. I should probably reword our ZED kudos a bit (smile). If I’m not mistaken the ATK also offers 27 mm boot length adjustment, in stock configuration. Lou

  12. Lou Dawson 2 January 8th, 2018 11:04 am

    Jbo, in my opinion it’s nearly worthless trying to standardize the influence of ski brake on binding release with ski touring boots. Reason being no standardized boot soles, changes induced by wet-dry conditions, and varied influence of afd whether sliding or not. As always if a user is at all concerned (most don’t seem to be), release needs to be checked for each rig specifically, as I think you told me you do at your shop? G3 goes against this by doing such careful calibration at factory, which I like but seems like a heavy demand on their resources when the accepted method is to wait till the exact boot/binding/brake combo can be tested and set in the shop, to the exact numbers the user wants. Definitely two ways of looking at this — provided the user actually cares and doesn’t just go to eleven. Lou

  13. Cody January 8th, 2018 11:40 am

    Man I was hoping for something with actual innovation from G3 🙁

  14. jbo January 8th, 2018 11:52 am

    Lou – Exactly right. In this case with “pre-calibration” and only one adjustment screw it would be nice to be deliberate regarding the brake’s effect. The Atomic/Salomon tech binding is in a similar situation with the only recourse being a macro spring swap to account for diverging values. The effect is more significant at lower values (e.g. women’s spring). The Dynafit Superlite 2.0 and Speed/SpeedFit have independently adjustable lateral release which is better at accounting for brake influence, albeit imperfectly. I feel this issue is glossed over in order to check a box for a brake feature which may expand the market. In my mind all the bindings in this “low-fat” category work best without brakes. You’re plan of not falling is still best!

    Also can’t help but think the ZED would be better off as a 4-10 binding instead of 5-12 (the ION LT 12 works well there). That should be an easy model to add though.

  15. Lou Dawson 2 January 8th, 2018 12:06 pm

    Well shoot, turns out the catalog weight I got was wrong. Instead of 310 per binding it’s 342 grams! That changes my take a bit for sure, apologies, that’s what I get for being one of the many panting bloggers too quick on the trigger. 342 reinforces your comments Jbo. Lou

  16. Lou Dawson 2 January 8th, 2018 12:16 pm

    Jbo, I did a tattered napkin sketch of what I think will be available in tech binding models next fall, seems like there could be upwards of 100? What do you think?

  17. Lou Dawson 2 January 8th, 2018 12:29 pm

    Cody, in all seriousness, tech bindings have evolved to the point where they’re close to alpine bindings in terms of innovation. Meaning what we’ll mostly be seeing is incremental improvements, especially since innovation is constrained by the boot fittings. For anything radical to happen with innovation, the boot fittings would need to be redesigned along with the rest of the system. Trab has tried to do that, with some success, but they didn’t get far out enough in my opinion for what they did to be considered radical, though it is appreciated. Lou

  18. SteveR January 8th, 2018 12:41 pm

    This afternoon My wife broke the AFD on her IONs for the third time. Each time the binding has broken in normal use (no falls, no cliff hucking) Please tell me that the new binding doesn’t have a sliding AFD!

    Zero ramp gets our vote as she likes skiing like that and I like the idea of not having to manufacture 10mm toe shims.

  19. Michael January 8th, 2018 12:43 pm

    Looks great. Has everything I would want in a general (not race weight) binding at a very competitive weight (on par with the Salomon MTN): adjustable release values, 3 riser positions, and BSL adjustment. If it proves to be durable G3 should have a winner.

  20. Lou Dawson 2 January 8th, 2018 12:48 pm

    I like sliding AFDs on tech binding brakes about as much as I like a glob of something else on my shoe (smile). They’ve been an incredible waste of resources, as well as I don’t recall one that’s not been fragile.

    I don’t remember the ZED AFD being a slider, but I’ll check.

  21. Tom January 8th, 2018 1:37 pm

    What’s the ramp delta head- toe? Same as standard ION?

  22. Tom January 8th, 2018 1:39 pm

    Ooops, I meant ramp delta toe – heel, of course…

  23. Lou2 January 8th, 2018 2:26 pm

    Ramp is zed, zero, didn’t i mention that?

  24. jbo January 8th, 2018 3:04 pm

    Lou – We’re definitely getting spoiled with choices!

  25. Lou Dawson 2 January 8th, 2018 3:28 pm

    All, I’ll add a few climbing aid heights into our ramp chart. Looks like the ZED high climbing aid is 9 mm lower than ION and 21 mm lower than a classic Dynafit TLT. Scroll chart to right to see the climbing lift heights.

    I express the climbing aid heights in “amount above toe pins” rather than an angle, this results in numbers that should be used for comparison between bindings. This should be very clear to those of you who like high heel lifts, for example in the case of TLT vs ZED all you have to do is visualize your boot heel being 2 centimeters higher, which is significant.

    Lou

  26. XXX_er January 8th, 2018 4:33 pm

    Unless you are some kind of Rando racer, I just don’t get the U spring bindings so at least the vertical and lateral values on th ZED are adjustable but I need to go one higher on the vertical release than the lateral and it doesnt look like the ZED does this?

    yeah the RAD 2 is also using a plastic post so i guess G3 thot they should follow suite?

  27. Nick January 8th, 2018 8:35 pm

    So they calibrate the release scale on each binding. Makes me wonder how much the release values (on G3 and other tech bindings) change as the cam lobes etc wear with use, let alone if you do something like replace a spring (as I had to do on my Dynafits after the adjustment screw worked loose and fell off). Not that it really worries me as after adjustment to reduce pre-releases I ski them on a higher numeric setting than my alpine bindings.

  28. CR January 8th, 2018 9:44 pm

    Not that impressed with new tech review, when I’ve got issues with brand new Ion 12s. Maybe I’m feeling a bit bitter, I’ve had my brand new ION 12’s out for 2 tours and had the right ski heel auto rotate from walk to ski mode 3 times – twice on one uptrack. Am I doing something wrong. Both heel pieces were rotated to the right (per the G3 video instructions for right handed turn heel right). Maybe pins should be on the inside?

  29. Jim Milstein January 8th, 2018 11:02 pm

    Agree with jbo that brakes can add friction and unreliability to binding function. Given that a ski with a brake can still be lost in bottomless powder or can skitter down a steep hard slope, what’s the point? Lou’s solution, Do Not Fall, is best and is the one I emulate, but with stretchy leashes as backup.

  30. Mac January 9th, 2018 5:33 am

    I must be missing something, while the ZED looks like a fine binding, I don’t really see how it is significantly different than G3’s ION offerings (aside from a very small weigh saving).
    Any chance of a comparative evaluation between the ZED, ION and the Backland to highlight the differences and the best applications of the respective bindings?
    Cheers.

  31. Matus January 9th, 2018 6:03 am

    @Mac I would say that ZED is aimed towards weight sensitive skiers. It saves weight significantly comparing to ION (200g/piece is a lot). ION is not considered elight.

    Atomic is a different story: simple, more metal, different brakes, a tiny bit lighter than ZED – great for someone who does not need to care about heel adjustments (me)

  32. Kjetil January 9th, 2018 6:59 am

    CR: check out this video from G3 – auto rotation tips starts at 1:28.

    https://www.genuineguidegear.com/life/video/field-tips-g3-ion-binding

    I had some auto rotation issues myself in the beginning with my Ion LT 12. Having the pins facing in eliminated the issues for me.

    Regarding the ZED: Looks somewhat promising, but those thin screws into the plastic is a strange decision. I have sheered off maybe 8 top plates on Dynafits that have the same solution, and know more people who have had the same issue. If G3 haven’t had any trouble with the ION top plate, I don’t understand why they would change to a weaker solution?

  33. XXX_er January 9th, 2018 11:13 am

    ” Regarding the ZED: Looks somewhat promising, but those thin screws into the plastic is a strange decision. I have sheered off maybe 8 top plates on Dynafits that have the same solution ”

    This is a good point and I agree

    Exploding top caps could happen to just about every RAD1 binding currently out there, which is why RAD2 clips under tabs on the heel piece before being screwed down and ION uses machine screws coming up from the bottom into the top plate

    I’m not sure why they would re-use a design that has had so many problems??

  34. Lou Dawson 2 January 9th, 2018 11:29 am

    Xer, the design of using 4 thin screws in plastic to attach classic tech binding top plate is perhaps the most fraught thing ever in the history of these things. Even the early Dynafit TLT-Comfort-Tristep would experience the screws simply breaking now and then, Plum had theirs break, and then we had the epic with Radical top plates exploding… I’ve hated every minute of that stuff — would much rather blog positive.

    So yeah, this is a legit concern with ZED.

    BUT, good engineering can solve such problems. G3 has an excellent QC program that involves brutal cyclic testing, and they’ve had field testers out on the ZED for a while now. Nonetheless, as with any tech binding I’d recommend folks would only purchase this binding if they’re comfortable with being part of the great ski tour binding consumer testing program of the Western World. It’s cool, fun to blog about, will be enjoyable to test — but.

  35. XXX_er January 9th, 2018 11:58 am

    I personaly never seen the problems on tech bindings using a post style heel lift

    IME the rampant screw breakage started on RAD1 with the flippy lifter design which created a triangle with NO hypotenuse … NO support

    AND the ZED has flippy lifters so hopefully the screws are very long, very strong

  36. Lou Dawson 2 January 9th, 2018 11:58 am

    For grins, anyone care to calculate the force that top plate has to endure when stomped on in touring mode (to keep it simple, no leverage)?

    The assumptions I start with, skier dropping heel in a sort of “free fall” motion:
    Skier weight 90 Kg
    Heel drop 10 centimeters
    Impact time .5 second
    — Result in the skier heel hitting binding at 1.3889 meters per second

    Impact force calculated using this website:
    http://calculator.tutorvista.com/impact-force-calculator.html

    1112 Newtons = ~113 kilos

    So for cyclic testing, to achieve this G3 should be dropping something like a 100 Kg weight over and over again from a height of 10 centimeters, or less weight from more height, or?

    In any case, my calcs perhaps show why binding top plate screws tend to fail.

  37. XXX_er January 9th, 2018 12:38 pm

    maybe ZED used a different designer than ION !

    I also know a guide who has broken 8 Rad heelpieces, I have broken them, my light friends have broken them so If I’m on my Rad heelpiece’s I tread lightly and I inspect them often.

  38. Kristian January 9th, 2018 1:14 pm

    Nylon is strong. Should these parts be made (machined) from materials like that?

  39. Kristian January 9th, 2018 1:16 pm

    And most importantly: strong at cold temperatures. (comment edit…)

  40. Lou Dawson 2 January 9th, 2018 1:20 pm

    Most (if not all) ski gear companies have cold temperature testing capability. More or less. G3 has a really nice walk-in freezer they take to 30 below zero F and do durability tests. I’ve also seen other companies that just use a chest freezer, not as impressive but can be made to work. Lou

  41. CR January 9th, 2018 1:20 pm

    Kjetil , thanks for the tip on the video. I guess my instinct was right to rotate pins inward. Weird though later in vid, it says to rotate pins outward when walking on highest heel lifts….

  42. Bryan January 9th, 2018 5:31 pm

    This binding looks great, and I’d love to purchase it!

    Am I able to buy it right now (I’m ready I’m ready I’m ready) from your ad partners at Cripple Creek?

  43. ryana January 9th, 2018 6:34 pm

    Every new iteration of G3 binding look more like Dynafits from five years ago.

  44. Lou Dawson 2 January 9th, 2018 6:59 pm

    Ryana, think of it as similar to alpine bindings. This sort of “classic” tech binding is going to look very similar whatever year or brand. Compare on the details, such as the truly great ION toe spring strength and geometry.

    The binding teardown is a very excellent Wildsnow tradition. I just wish it were universally applied (I’m thinking of one rather unusual toe piece in particular). Great looking binding, but I still dig the Ions. And Matus, maybe not relevant to your question re. U vs Z heels, but there are only a few different U springs available for bindings that use them, Z is essentially infinitely variable. And the accepted method for setting rv may be release testing in the shop, but how many people/shops actually do that? (Also, check the demo plate weight in the third photo caption.)

  46. Shop guy January 10th, 2018 9:00 am

    I’m really hoping G3 get this one right. 1 or 2 broken or faulty Ions walk through our front door every week when the snows flying in our fairly small, albeit active mountain town. No binding is perfect and without some flaws but the Ion is a headache and sees way more problems than any other tech toe binding out there.

  47. Lou Dawson 2 January 10th, 2018 9:40 am

    Every year I get harsher and harsher on the tech binding durability issue. You wouldn’t believe the flack I get from companies when I don’t include their never consumer tested product in my “ultimate quiver” roundups. More times than not, I’m proven right to be careful, as the first-year product ends up breaking or otherwise malfing, and needs an in-line manufacturing change or even a recall. Sick of it. Look for us to continue ramping up our approach to this in that we’ll be very skeptical of any binding in its first year. We certainly won’t be handing out awards to products that end up breaking, as is common with magazines seeking to play the awards game.

    Shop owners, if you are seeing a common breakage or malfunction of any binding, hearing from you in private would be very helpful. You can use contact option in menu above, or private message on Facebook.

    It would be helpful to say what parts usually break or how the bindings usually malfunction, Shop guy. Lack of specific details make it harder to distinguish legit “reviews” from fake ones, in my opinion.

  49. Lou Dawson 2 January 10th, 2018 10:36 am

    See, I constantly struggle with this, as I do want to help consumers with breakage issues, but don’t want to whip up a frenzy of IAS that’s unfair to everyone, consumer and makers alike. I no doubt blow it now and then, but try my best… Lou

    Lou its pretty obvious to me if you are not careful on what & how you say things you won’t be invited to see the new stuff, you are caught between a rock and a hard place

    Your efforts are very much appreciated, Lou, and I think you do a great job keeping it real here on Wildsnow. But there’s only so much that is possible given the nature and scope of the internet. As much as I would like to be able to rely completely on comments for information re. binding durability etc., I think it’s important to be skeptical, especially these days.

  52. Lou Dawson 2 January 10th, 2018 11:49 am

    Totally agree, the ski touring industry has in my opinion done a grade D job with quality control. It just goes on and on and on. It’s probably going to take some really expensive lawsuits or the involvement of entities such as U.S. Consumer Product Safety Commission before the companies can slow down and do more extensive testing before foisting defective products on the public. We the consumers are so eager for improved products we don’t seem to vote much with our wallets.Lou

    At the other end of the spectrum, I’ve got several pairs of Dynafit Vertical ST bindings that I’ve been skiing on for years with no problems – no breakage, no pre-release, but release when needed, no icing, no brake failure, etc. – they just seem to work.

    I’m not a big guy, try to ski smoothly, don’t fall much, and am not hard on equipment, so I wonder what the realistic lifetime of these bindings may be – 10 years?, 20 years? – like some of the alpine bindings of old?

    Were the Vertical ST just made better? A simpler design? I still like that I can switch to ski mode with a twist of my pole, instead of having to bend over.

    From comments here (and I realize negatives tend to be emphasized), and the hefty price of new binders, I’d just as soon stay with what I’ve got.

  54. Lou Dawson 2 January 10th, 2018 5:25 pm

    The ST broke, first and second year, I recall…

    – tab your foot sits on when flat on ski broke off
    – heel tower climbing aid broke until they pinned it with a roll pin
    – Toe chassis of FT version cracked

    But I agree it’s been one of the better Dynafit models, multiple pairs still in use by WildSnow.

    So two different points.

    1) I don’t get why people aren’t borrowing from the brilliant Kreutspitze design, which has separate vertical and horizontal release settings AND is much lighter than anything else but race bindings.

    2) Something not well advertised is that the Salomon/Atomic MTN/Backland binding accepts Plum crampons, which are vastly superior to the old slide-in Dynafit-style ones, and pretty much on par with (or perhaps better than) the G3 design. You just drop them in vertically, they don’t slide around, and icing is not the problem that occurs with side slide-in crampons.

  56. Shop guy January 10th, 2018 7:04 pm

    Ion issues: Brake engaging during walk mode, brake getting stuck (I actually had 2 bindings new out of the box that had a brake that would not release). Also the turret recall along with broken plastic plates under heel riser cracking. There was also the spring failure in the risers in an early generation. I haven’t seen any issues with the ion LT but it is not nearly as popular as the brake version. I’m only listing cause someone asked. G3 are a good company, but I fear a lack of R&D maybe an issue for them, they are small after all. I wish them the best of luck with this binding but our shop, along with a lot of users will remain skeptical for sometime. Prove us wrong G3.

    ATK has a large offering and some have similar features to Kreutspitze.

    ATK bindings are being re-branded as Hagan, Fischer, and Kastle that I know of. And rumored for a Utah equipment company next year.

  58. See January 10th, 2018 8:52 pm

    Thanks, Shop guy. I have to admit, I asked for details in part because broad statements like “(product x) sees way more problems than any other tech binding out there” without specific evidence to back them up sound suspicious to me. That said, I’ve had most of the problems you list with other bindings as well as the Ions. I don’t know about the broken plastic plate, and the “turret” problem could be serious, so I’m glad they implemented a recall. But the other stuff seems like par-for-the-course for tech bindings, in my limited experience.

  59. VT skier January 10th, 2018 9:05 pm

    My ION LTs are 456 grams each (no leash) . So only 110 grams , per binding heavier than this new Zed.
    Toured on my ION LTs today, they worked fine. I just miss being able to spin the heel with my pole , like my Speed Turns and Verticals.

  60. Kjetil January 11th, 2018 5:39 am

    VT Skier: Why the need to spin the heel on Ion LTs like on the old Speed Turns? The Ion heel riser flippers are awesome, and at the top just knudge the binding with your upper end of your pole to turn it, step in and rip skins! Check this video:
    https://vimeo.com/178934016

    To my recollection all bindings eventually shows some flaw or break. I have broken Dukes, Barons, Marker Tours, G3 Onyx, Dynafit Radical FT and ST, Dynafit Beast, Marker Kingpin and G3 Ion throughout the years. I’m heavy on equipment, so I have pretty much learned to accept it. I just have to remember to inspect my stuff regularly – especially before skiing things of high consequense.

    With that said; I would not mind skiing the ZED, just that I would monitor those 4 screws like a hawk!

  61. Jürgen January 11th, 2018 7:19 am

    Markers new Alpinist is starting to put pressure on the pricing in the low tech market. Looking forward to Lou´s respective report, especially to the brake locking system being used.

  62. Kristian January 11th, 2018 7:32 am

    And let’s remember that pin bindings are tiny touring bindings for svelte endurance athletes.

    Many are now using them as full on resort and free ride bindings even though they have little mass to absorb that abuse.

  63. GOB January 11th, 2018 8:04 am

    Hi Lou.
    Are the demo plates for the heel only? Or are there 2 separate plates that let you move the toe as well?

  64. Lou Dawson 2 January 11th, 2018 8:24 am

    Heel only. We don’t really mind that much anymore, as most skis have a fairly big sweet spot. Nice when it’s provided, however, and of course essential for specific ski testing. Lou

  65. VT skier January 11th, 2018 7:25 pm

    Kjetil,
    Thanks, I will try that, banging the lifters on one side of the heel to spin the binding into ski mode.

  66. Mike January 12th, 2018 3:49 pm

    Lou,
    What’s the Fly Ride ski all about? Wasn’t in your new skis from G3 post.
    Thanks, Mike

  67. Lou Dawson 2 January 12th, 2018 4:44 pm

    Not sure why they have this video from 2010, but in any case:

  68. Eric Steig January 14th, 2018 9:37 am

    To JBO about weights — I dunno that these comparisons are fair. ATK and Salomon and Kreutspitze don’t have the dynamic compensation that the G3s have. The ATK brakes are not comparable — some say insufficient for anything but light skis or shallow slopes, etc. etc. To each his own.

    Meanwhile, loving my Salomon heel risers with zero chance of autorotation, which you guys at Skimo sold me!

  69. Kjetil January 14th, 2018 10:13 am

    VT skier: don’t bang the lifters. Just push the back part of the binding (which is turned out towards the outside ski edge in walk mode).

  70. Mac March 21st, 2018 2:15 pm

    Hi Guys,

    I am somewhat conflicted, and am in need of some sage advise. You see, I was planning on upgrading my ski and binding set up this upcoming NZ winter and had pretty much decided on G3’s FINDr with the Ion – then they go and put out info on the Zed, which won’t be available until AFTER the NZ season!

    So my question is, in your most excellent opinion, is it worth a) waiting for the new Zed binding and b) is it a wise move to buy the first years production version?

    There isn’t actually anything wrong with my current rig – I’m just looking for a slight backcountry, ski-mountaineering oriented performance upgrade. I tend to do about 30% of my skiing on-piste (ie until it softens up enough to go BC), so only run a ‘quiver of one’.

    Any thoughts or advise greatly appreciated.

  71. XXX_er March 21st, 2018 2:52 pm

    My take is that the Zed is held together with what are basicly wood screws into plastic in the same fashion as Dynafit did for years which was no problem on the Vertical/comfort design

    Until Dynafit changed the heel lifter design which caused a lot of grief for RAD1 owners when the flippy heel lifters broke the top plates off the heel pieces, the flippy lifter system is similar on both brands I know people who have broken 6 RAD1’s

    Dynafit changed the top plate design on RAD2 so it would clip on to the heel piece instead of depending on wood screws into plastic,

    I don’t know what G3 was thinking when they changed the top plate retention on the Zed back to using screws in plastic?

    Especialy when G3 used/uses machines screws into a metal frame on the ION to sandwich the heel piece together

    IS nothing learned … I would go ION and be happy

  72. Lou Dawson 2 March 21st, 2018 3:07 pm

    ION is now venerable and recommended, though I’m not 100% happy with the brake retention. I like the version without brakes… Lou

  73. Mac March 22nd, 2018 1:10 am

    Cheers for the feedback – it tends to reinforce my thinking of going with the original plan of mounting IONs on a set of FINDrs.
    It’s not as if I’m doing massive, multi-day missions, and we do tend to get a lot of ice on my home mountain, so combined with a fair bit of on-piste skiing something a that is likely to take a few knocks at the expense of a few grams looks the way to go.
