G3 ION Binding Template and Screw Layout


This post by WildSnow.com blogger  
G3 ION tech ski binding, copy of the standard tech binding with enough added features to set it apart.

G3 ION tech ski binding, based on the standard tech binding but with many small changes and definitely a different screw mounting pattern.

Word from G3 is they designed ION screw pattern (and mounting position on ski) to have the least overlap possible with existing tech binding mount patterns. Moreover, the layout is wider than most tech binding screw patterns.

ION pattern is 40 wide x 45 long (mm) mm at toe and 36.5 x 52.5 long at the heel.

Major brand popular tech binding model is 30 mm wide x 40 long at toe, and 32 mm wide x 53 long at the heel. That may sound like it’s still close, but ION appears to place the screw holes in significantly different positions once the boot is matched to its correct position on the ski — thus preventing overlap if you want to change binding models/brands or buy used skis with the ubiquitous tech binding screw holes. (I’d make a graphic comparing the two screw patterns, but it would be misleading since they end up quite differently in terms of fore/aft, depending on boot size as well as optional adjustments in fore/aft binding position.)

For those of you concerned about how wide your binding mount pattern is, note that ION is significantly 10 mm wider at the toe, and insignificantly wider at the heel.

If you want to play around with ION mount pattern (or mount IONs once they’re available), here is the link to our WildSnow ION paper mounting template.

ION will be available at retail this coming fall of 2014.

    Is their a G3 ION for snowboarding bindings? I think these would come in handy for snowboarders.

    Can You please indicate where the pins would go in that template? Preferably, both toe pins and heel pins (on both adjustment extremums). This way we will know how the boot will fit into equation. In current state, w/o knowing where the boot will land, (and keeping in mind that You provided us with measurements between holes) this template usefulness approaches zero :-(

    Everything about that looks like it will break

    Looks pretty sweet to me. I am pretty excited to see more competition for dynafit. The market has suddenly become competitive, and innovation is the result. The anodized aluminum is gorgeous. I was reading a boot review here and was amazed at all the negativity that is cropping up here on wildsnow. Lots of armchair quarterbacks telling how a product could be better and then the group complaining about a race boot not being stiff enough for their freeriding. I guess Lou has to take some of that blame since he is always picking apart the gear. I definitely don’t need to hear comments disparaging a product because it doesn’t meet their needs, when they are not the target audience. The innovation right now in alpine touring is staggering and I applaud the manufacturers for the incredible design work that is being done. I am hopeful the backcountry innovation will drive alpine gear to up their game as well.

    Me, there is no standard measurement between toe and heel (though I’d imagine the G3 mechanical mounting jig will work to some arbitrary standard that probably will place the heel’s boot length adjust midway in the range), you simply mount it using the boot as a gauge for position of binding on ski. Child’s play.

    The template is far from useless, anyone familiar with mounting tech bindings could use it and mount an ION binding in their sleep.

    But yes, pin position at least o the toe would be useful for comparative purposes so I’ll add it. It’s tough to figure out exactly by just looking at the binding, but appears that the pin line (left/right line) for the toe is centered fore/aft between the two screw pairs. I’ll check with G3 and add a line to the template.

    BTW, in case you missed the memo (grin), the technique for DIY mounting using this sorts of templates is to snap your boot into the toe unit, set toe unit on ski with boot lined up with ski mounting mark, mark hole positions, then match template to the hole positions to set for/aft position. Same with heel. Adjust to midrange, set boot heel down on ski, mark binding position, then match that with template. It’s super easy, don’t over think it.

    Kevin, I’ll take whatever blame is appropriate. My take and publishing endeavors are most certainly not perfect! And I do agree. I’ll admit I’m fed up at times with people trying to force ski products to do what they’re not designed for. It’s like driving a European motorway at 120 MPH with tires that are rated for 90 MPH, then complaining when you get a blowout and end up doing sheet time. ON THE OTHER HAND, a bit of forcing products outside their envelop is indeed what drives innovation. It’s just that it needs to be done realistically and with a positive attitude, not just a source for whining. Lou

    “Least amount of overlap”, correct me if I’m wrong but swapping out Comforts, Verticals and Plum Guides is impossible, no?

  8. Lou Dawson February 12th, 2014 5:07 pm

    Using same holes? To one degree or another, yes, but not perfectly.

    Most modern skis can have a few extra holes with no detriment, so long as they don’t overlap. And even if a few overlap it can still be made to work in most cases.

    I should clarify. Can the Ion be securely attached to skis already drilled with the Guide, Vertical pattern? I would think no, but I’ll defer to those with more experience.

  10. lou dawson February 12th, 2014 8:29 pm

    Actually, probably yes.

  11. Jailhouse Hopkins February 13th, 2014 8:25 am

    Probably ain’t exactly reassuring, especially when its a pair of dps skis!

  12. Lou Dawson February 13th, 2014 8:44 am

    Jail, if you download both templates, you should be able to figure out the relationship, just figure boot position with ION is boot toe tech fittings are midway between the front pairs of holes. I’m checking on that to be sure, but close enough for estimating a comparo. I have an ION binding here, but it’s difficult to exactly measure the toe pins position as compared to the screw positions.

    I can tell you for sure that the toe holes will not overlap though the front pair will be close. Heel is what you want to compare.

  13. Jailhouse Hopkins February 13th, 2014 1:12 pm

    After downloading the Guide’s template from Binding Freedom, the toe holes will be okay, but overlap on all four heel holes are present.

  14. Lou Dawson February 13th, 2014 2:09 pm

    Jail, the heel holes are optional in that you can adjust the binding heel a bit forward or back so when you’re boot is in, the binding heel falls on the ski in such a way as to prevent overlap. Another thing to remember is that the ION has no tech gap at the heel. My guess is that the default heel screw holes for Plum vs ION has no overlap due to the above factors. I’ll try to add more to template to make this clear. Waiting on some information. Lou

  15. Jailhouse Hopkins February 13th, 2014 2:24 pm

    Hence the deferral! Much appreciated.

  16. Lou Dawson February 13th, 2014 6:02 pm

    Looks like ION toe pin left/right line is approx 5 mm back from midpoint between screw pairs. Am updating template.

  17. me February 14th, 2014 9:48 am

    Lou, thanx. Now at least we’re able to calculate the distance between old and (theoretically) new holes.

  18. Lou Dawson February 14th, 2014 11:10 am

    No problem Me, I understand the need for knowing where the binding toe pins locate fore/aft. As for the heel unit, let me repeat that they have enough fore/aft adjustment to almost always be able to locate so you’d get no screw hole overlap.

  19. Jailhouse Hopkins March 19th, 2014 8:57 am

    Template updated?

  20. Lou Dawson March 19th, 2014 10:07 am

    Updated in what way? I did add the Pin Line… Let me know. Thanks, Lou

  21. Jailhouse Hopkins March 19th, 2014 4:17 pm

    Ashamedly, I do not know the relevance of the toe pin line. Explain please!

  22. Lou Dawson March 19th, 2014 6:53 pm

    It’s so you can quickly figure out if screw holes will overlap with an existing binding mount, or even doing a really fast mounting job. Best however is to clamp the binding to the boot toe, set the assembly on ski, line up boot with mark on ski, mark one or two screw hole positions, then line up the paper template with the marked screw hole positions.

Got something to say? Please do so.
