Overview of next gen tele bindings

DIY tele tech bindings are thriving.  TTS cable with a G3 Ion toe.

DIY tele tech bindings are thriving.

I was really hoping to end this season with a set (or two if they skied similarly) of bindings that I could go into next season with and be confident I had a good setup. I’m pretty close, but I need more time on these setups to have more confidence. And I don’t have two similar setups, so I will have to make some changes.

Here is a brief overview of the bindings I tried over the last two years: Rottefella Freedom, The M Equipment’s Meidjo, Burnt Mt. Design’s Spike, two pair of DIY TTS bindings, one with a Dynafit toe, the other a G3 Ion toe. Here’s my synopsis.

Rottefella Freedom

A negative ramp angle on the toe helps with faster turn initiation and bellows flex.

Rottefella’s NTN Freedom

  • Internet research told me these were the NTN bindings to buy.
  • I found them to feel heavy — they are heavier than others, but the weight in front of the boot makes it more obvious. (Ed. Note: as does the small but noticeable touring resistance).
  • They lack edge control; the low heel, high toe combo makes it physically difficult to angulate.
  • Sluggish — a combination of the above two issues.
  • I was able to sell 2 pairs though, so people still like them.

The M Equipment’s Meidjo

Meidjo. Skis great, tours better, but causes "boot jack."

Meidjo. Skis great, tours better, but causes “boot jack.”

  • Neutral stance with heel/toe-height just right.
  • The holy grail of features really draws me to this binding.
  • Precision and confidence — the combination of the tech toe and impressive lateral stiffness [deliver] excellent edge control [with a] smooth, progressive flex.
  • The deal breaker for me is the snow pack underfoot which gives boot jack. I have tried wider skis (87 to 105 underfoot), foaming, taping the gaps…without eliminating the issue. Not too bad if the snow isn’t deeper than 15cm and dry.
  • I have pre-released, but only when the duckbutt [clamp] became full of snow while skiing and it released upon landing off a jump. Never from the toes as with other tele tech [bindings].
  • I will hang on to these for now, but they are no longer mounted.

This is a funny one. There is nothing wrong with these bindings, yet I still don’t feel like they are what I want to use everyday. They are my backups right now.

  • These bite the toe of the boot and have excellent lateral stiffness. They hold an edge well and give confidence. Can be made very powerful!
  • They are super adjustable in every way you can imagine.
  • Initially my toe would slide back out of the spike’s ‘jaws’ but was sent a different baseplate that holds the toe in very firmly. Now, the boot CANNOT lift. Which some people may like. I can get used to it, but I prefer the boot (ahead of the bellows) to lift a little bit (less toe crunch).
  • Despite being step in, they can be hard to get on in soft snow or on the side of a hill.

DIY Tele Tech w/Dynafit Toe

Components: Dynafit Comfort tech toe, Voile Switchback springs, OMG Cable Rod & Block, Voile heel lever.

  • I have spent more days on this setup than anything else this season. I really like them.
  • I run the Dynafit shim under the toe. No shim under the TTS block and use a 15mm heel. This gives the bellows a small gap that allows some flex in the boot.
  • Travel with the Switchback [springs] is okay. I do hit the end of spring’s [travel], but by the time I do it’s about where I’d stop anyway. This makes me wonder about long term durability though.
  • I just switched from TX Pro 27.0 to 27.5 and I am feeling the end of travel more with the bigger boot – it’s that close!
  • I have skied these hard in all conditions including boiler plate ice for several days after a refreeze and they never pre-released.

The drawback of this setup is the toe: stepping into it is a pain and having to lock it all the time is an extra step. I am also noticing the TTS wires are bent and the channels in the TTS block are already quite worn (not sure how many days on these, but I got them this season and I’ve skied a lot of other skis too)

Bottom line: I really like and trust this setup now. Nice lateral stiffness to the heel. I just don’t know if the lack of travel will cause a failure long term. And the step in could be improved. I’m looking forward to more days on this one.

DIY Tele Tech w/G3 Ion Toe

The favored rig. DIY tele-tech binding with G3 Ion toe, OMG cable assy. with long springs, Hammerheel, 2-prong.

Mounted with a standard Ion toe and shim, 12mm shim under the OMG-TTS cable block with long screws, and a Hammerheel with an aluminum stabilizing prong (a Moonlight idea). I haven’t spent much time on the final version of this setup yet, but the days I have spent have been testing hard and pushing outside of the normal limits. I am expecting this setup to be the winner.

  • Super nice to step into. Stepping into the Dynafit or Spike feels tedious by comparison.
  • I added an aluminum prong behind the hammer heel made out of cut-and-filed channel aluminum. This fits into the low tech slots and holds the heel well and really improves edging performance on firm snow and paralleling.
  • The longer springs require a wire that bends out further around the boot (short TTS). This takes away lateral rigidity and therefore requires the prong to offset it.
  • I have never found the end of the abundant travel in these long springs.

Note that I am skiing the Voile lever on both my TTS setups. Even though the TTS lever ‘feels’ like it snaps in with more force, they don’t seem to hold the boot’s heel from moving laterally as well as the Voile lever.


Unfortunately, no two bindings feel the same. I’d like to be able to switch seamlessly between skis. I’d look at putting the long TTS springs on with the Dynafit, but I haven’t tested them enough to be sure – and I don’t like the old Dynafit toe for stepping in.

I do plan on getting a pair of Moonlights. My guess is they will be most like the ION setup, with a few differences (maybe improved lateral stability at the heel, hopefully a nice step in guide to improve on the Dynafit).

I’ll keep skiing all this stuff next year but suspect that I have some pretty solid kits in my ION TTS and the Dyanfit TTS with Spike as backup. Moonlight might take the place of the Dynafit kit with short springs.

    How does the 22-Designs Outlaw compare?

  • RC

    I added a shim to my freedom heels (3mm) and they ski much better. They are still heavy and prone to losing parts (caps, rubber mid piece) and clog when the snow is wet.
    I have an older TTS setup as well, can I add the longer springs easily (and cheaply)?

  • Travis Nichols

    Thank you for sharing this! Can’t wait to hear your results with the Moonlight. Please keep sharing formal summary articles like this on this topic!

  • teledorth

    im not sure he’s been able to test them for himself

  • Dostie

    Outlaw is a different animal – no tech teeth. Those who have skied it seem to love it. No news is good news, meaning there have been very few reports complaining about ‘em. Super easy step-in function (without brakes).

  • Tom

    craig,what do you know about acquiring longer springs for the tts bindings ?

  • James Howat

    I just purchased a TTS heel kit (large) to use with D-fit Vertical toes and size 27 TX pros.
    I have not mounted them yet because it seems like wire that attaches to the ski will bend or need to be bent to allow the heel lever to seat properly. I inquired through the O.M.G./TTS web site and have not received an answer. You mentioned that yours have bent during use. Is that ok?

  • jnicol

    They are now available through OMG (TTS). And I suppose moonlight – what you require depends on what you are attaching them to.

  • jnicol

    Well, I guess that is one of the questions that time will answer. For now they are fine and seem to have bent to where they needed to be and have stayed there. However, I was looking at putting a narrow short wire on with the long springs and I think the location of the bend would have been at the springs… In other words, it wouldn’t work.

  • Giovanni Calcagno

    Got the following setup for touring : ATK Tech Toe with active ski brake, kreuzspitze cable assy, Voilè made Moonlight long springs with 29 Scarpa TX.
    Moonlight springs became too soft after three runs ( I mean runs not days) and wasn’t able to get the heel levers to engage properly anymore (my buddy has 27 size and didn’t have the same problem, has been skiing with them the whole season).
    I tried with Rottefella medium springs, they are as long as the Moonlights and after a couple of days they seems to be ok.
    I have been skiing in resorts with Freedom for the last too season and never felt they lack edge control. I don’t understand how it could have any relation to the high toe low heel combo.
    Tried Meidjo a couple of days, I agree it skies great but snow buildup is a serious problem ( even worst than with Freedom) and if you put the brakes on engaging the toe gets really difficult ( and brakes are not compatible with Crampons).
    Tried also the Outlaw: skies well, aluminium bombproof appearance, no resistance in the uphill mode but some difficulty in releasing due to ice buildup.

  • James Howat

    Thanks for the reply. I am going to bend the heel wire up 1 inch ahead of the cartridge so the wire does not kink right at the cartridge. This may only improve the aesthetics and make me feel better that the bend was deliberate rather than incidental…..

  • samesamedifferent

    How does the heel units for your TTS setups compare? Is it because of incompatible heights that you added shims under the tech toe?

  • TractorTraylor

    I’m currently putting together an Ion TTS binding. Has anyone experimented with Black Diamond O1 springs with TTS?

  • Dostie

    Two problems are likely to arise. The heel lever won’t latch tight on
    the heel step and the spring travel will probably limit out with deep
    knee tele turns. The community of DIY TTS’ers look forward to your
    report though on how well this combo works (or not).

  • andulin

    If you decide for the Meidjo, just be sure you take a couple of Voile straps with you: this is how I managed to get back home (telemark skiing, BTW)
