Another revelation by Dynafit: a binding for touring AND freeriding.

Once again expanding the downhill performance of its freeride bindings, Dynafit introduces the TLT Radical FT Binding, which boasts the most powerful descent capabilities to date with the same lightweight, trusted Dynafit design. The TLT Radical FT is made with the strongest, lightest materials possible, including a carbon binding plate that connects the toe and heel pieces and provides incredible rigidity underfoot. With help from the reinforcing Side Towers on the toe piece, ski mountaineers and big mountain backcountry freeriders get the downhill security necessary for dropping into icy cirques and mile-long couloirs.
  • Features release settings from 5-12, which suits the rowdiest backcountry skiers and ski mountaineers
  • Carbon plate features a switch that locks the plate in place for torsional rigidity and that creates a platform that more directly transfers power to your ski
  • In its locked position, the carbon plate also yields dampening over rough terrain thanks to rear rubber pieces
  • The extremely durable aluminum toe piece features Side Towers (or Power Towers) that help to provide easier entry and enhanced power transfer, and that prevent pre-releasing in the steeps
  • Speed Step heel riser provides three climbing levels and can easily be switched on the move with a ski pole
  • Front toe piece jig template uses only four new mounting screws instead of five
  • Includes brake (choose 110mm or 130mm based on ski width) so you don't lose your sticks during giant descents
  • At 75mm wide, this binding was made for wider freeride touring skis
  • Item #DNF0066

My first AT binding = success

  • Familiarity: I've used it several times

This binding is my first in the AT world, but so far I'm very happy. I wouldn't be surprised if eventually I end up with more minimalist bindings, but as someone whose quiver of pairs skis numbers only one (plus a beater backup), I wanted a binding that I felt could take some abuse on lift-served skiing, as well.

I have these setup on DPS Wailer 105s and use La Sportiva Spectre boots. I'm thrilled with the setup so far and have used it for backcountry touring, in bounds skinning, and standard lift-served skiing.

love it

  • Familiarity: I've put it through the wringer

perfect for day touring, light enough to bring you first up on the hill, when it comes to alpine - it stroke me even better, power transmission just amazing. Im aggresive skier and never expected that from tech bindings , it shocked me after first run. I wont be comming back to traditional anymore...

Lighten Up

  • Familiarity: I've put it through the wringer

For years I've avoided tech bindings for fear of failure and toured on everything from Fritschi Freerides, to Marker Dukes and Barons, and the Salomon Guardian. The distances I started going necessitated a switch since that extra training weight isn't great when its game day.

I paired these with the new Icelantic Vanguard and was blown away by how light the setup is. The bindings weigh in at just 2lbs 10oz and you notice it as soon as you pick up your skis. They felt light...almost too light.

For reference I'm 5'8 135lbs and ski aggressively.

I decided the only way to really test how they perform was to hammer on them all day taking resort laps, boosting features, and pounding bump runs. The initial click in was tricky, but felt much more solid than I anticipated. With toes locked the first turn was hesitant, but it felt like a really solid connection to the ski and I didn't notice any lack of power transmission. Three turns in I was charging making high speed wide open turns and boosting comfortably. Future runs I did unlock my toes and did have some softer releases when skiing in variable terrain. It is a safety issue to lock your toes, but in no fall terrain is a must. Disclaimer: You can still release from softer skis over flexing in lock mode.

I knew they were going to excel while touring. The stride of these is much more natural than the Marker Royal series, though I cannot speak for the Kingpin. Heel riser adjustments are a breeze and you can even click directly back into your skis without removing them (with some fiddling). Its a huge savings energy wise for not having to lift the binding weight and I noticed day 1 that my touring speed increase about 10%.

I have seen failures in the field on these bindings, but I have not experienced any failures thus far. All gear it is prone to failure after use. Maintain these bindings, carry a repair kit, and lighten your load. You will not be disappointed.

Solid Binding

  • Familiarity: I've put it through the wringer

Beefy binding I feel comfortable skiing any conditions in, backcountry and resort. I've taken airs on them and haven't had an issue. They ski aggressively and honestly can't tell a huge difference between them and my alpine bindings. Really impressive

Note: I am 135lbs...

Solid Binding

Once you go low tech, you never go back

  • Familiarity: I've used it several times

I was extremely hesitant to make the transition to low tech bindings because I like to ski fast, aggressively on wider skis and jump as well as a lot of negative publicity about earlier editions of dynafits and other low tech bindings having release, mechanical and reliability issues.

I use these with Scarpa Freedom SL boots on Kastle TX 107 skis. I weigh 160 pounds. I tested these in the Northeast in and out of resort on ice, groomers, moguls, spring touring on Mount Washington, sleet, powder and all the funky conditions we get in the northeast for ten days in spring 2014.


These bindings perform incredibly well on touring mode. I went from using alpine trekkers to these so the contrast was astounding. I also briefly used Marker tours prior to using these. The lightweight as well as the low profile of these make them very performant touring and climbing steep hardpack slopes in frozen spring snow conditions. Be sure to engage the lock position when touring up steeper slopes at an angle as they have both released at the same time on two occurences (not fun especially when carrying heavy pack).


This is where I was most impressed. This binding skis like a high performance alpine binding (Tyrolia freeflex, Look px). I put the DIN at 9 (same DIN on alpine bindings) and did not experience any release issues. The power transfer is like an alpine binding. I did not notice any difficulty in steering the wide powder ski (107 mm at skate). Even skiing the zipperline in the mogul course, I forgot I was on a touring binding. Even though I set my bindings at DIN 9, I believe it was the right decision to get this model that goes up to 12 instead of the other one that only goes to 10.


The lever to engage the binding in lock position is located at the front of the binding. It is possible that it may inadvertently become engaged while the user is skiing without user's knowledge, thus leading to a potential serious knee injury.

good binding, bad brake design

    Good binding so far (1 season, 15 days touring). Felt solid on the ups and downs (i'm 6'4" 220 without gear).

    However, the unremovable brake design is pure idiocy, particularly coupled with a flimsy afd plate that is prone explode (per my experience and my local ski shop's anecdotes). Customer service from dynafit USA was completely unresponsive to my emails (maybe they were all on vacation for the entire month of May 2014?).

    While I can't afford a new tech binding now, my next tech binding will not be a dynafit.

    Makes backcountry touring even more fun

    • Familiarity: I've put it through the wringer

    Okay, so it is well known that Dynafit bindings are lighter and therefore more user friendly than more burly offerings. Well burliness is not even a question, especially after hammering the TLT Radical F. I am a measly 150 pounds and don’t even come close to needing the DIN setting screwed up to 12 (I set mine at 8) but I still was tentative when I took them to Snowbasin on a hardpack day.

    At the resort, these bindings performed almost as well as my alpine setup. While bashing moguls, carving mach turns on groomers, and jump-turning through sluffing steeps, the bindings never pre-released or felt unstable at any time while in ski mode. However, I did notice a little bit of play in the toe when skate skiing across flats or going really fast with tight turns, and the toe piece would sometimes rattle annoyingly. Further research on the subject led me to believe that this toe-play likely has more to do with the tech inserts on my Black Diamond Quadrants than the binding design.

    So, the Dynafit TLT Radical FT passed the resort test. But the backcountry is what they are made for, and they excelled. Honestly, owning these paired with the Voile Chargers made me excited to tour again, and provided motivation to get out more. When skinning uphill, the heel lifters are super easy to engage. I had issues at first by using my pole basket to grab the lifters, and discovered that turning my pole upside down and using the rubberized grip makes going from flat to heel lifted super fast and easy. Same goes for putting them back into the down position.

    I am absolutely in love with my Dynafits. The total lack of weight while skinning uphill, coupled with user friendly heel lifters, and confidence-inspiring downhill capability make these bindings an obvious choice for backcountry skiers looking for the ultimate in touring and freeride performance.

    Makes backcountry touring even more fun

    These made me enjoy touring once again

    • Familiarity: I've put it through the wringer

    Dynafits have changed how I look at touring. Before, touring on a Fritschi or Duke set-up was a painfully slow and heavy experience. Then I bought these. I am in no way, an ironman athlete, so I need all of the advantages I can get. I ski these pretty hard and haven't had a pre-release yet. Sure, I lock my toes out when skiing, and have the DINs cranked in the heal, but no issues like you might think would happen. The pivot point for the toe makes walking feel as natural as possible while walking uphill in a plastic boot.

    ***Although lots of people ski in-bounds on these bindings, I still prefer the confidence of an alpine binding and boot***

    Also, I have been told one of their athletes that the center plate is a gimmick, and can be removed if desired. I did it and have had no problems.

    These made me enjoy touring once again

    Beartrap it

    • Familiarity: I've put it through the wringer

    I use these with the K2 Annex 118 Seth Morrison ski. They are very lightweight and excellent for skinning. Everyone I know uses them in the locked touring mode when skiing on them. I have had them release on me multiple times in ski mode so now I always ski them locked out. I had them adjusted by a Dynafit rep and was instructed on the proper way to use the binding and they still release during high speed chatter and variable conditions. I am using them with K2 pinnacle boots and I suspect part of the releasing issue could be coming from that boots tech fittings but I do not know for sure. Either way most serious skiers use these locked out for the descent. If I had know that I would have ignored the DIN setting listed for this binding and gone with a lighter more stripped down binding.

    I mounted them on a pair of Line Sickdays 110 and had exactly the same problem you are saying... Lots of pre-release so I decided to unmount them. I also have a pair of K2 pinnacle, maybe it`s a problem with the boots... Have you had any solution?

    The one that changed the game

    • Familiarity: I've put it through the wringer

    I came from a pair of Freerides (not sturdy enough for 195lbs long term) and Dukes which are like strapping a small lead brick to your feet. These bindings are the ones that have been around, but they are the only choice for stiff durability and efficient touring. Save your time, money and frustration by skipping the Duke/Freerides and getting the Dynafits!

    Going with Dynafits

      Just ordered these for my V-Works Katana.

      I hope they hold up to 50% resort, and 50% backcountry. I think this will be a great set up for tree skiing.

      Week at Jackson

      • Familiarity: I've used it several times

      Mounted them on a pair of S7's after my Fritschi's heel cock level (plastic) broke right before my trip to Jackson. At first I was hesitant on the TLTs but I got more comfortable after a few days on them. I also have a pair of Dynafit Beasts mounted on some Mantras. The TLTs are lighter and not nearly as beefy as the Beasts, but they seemed to perform just as well. I usually use a DIN of 7 or so, and the TLTs were fine with that. I did release twice; once while the toe lever was in "ski" mode, and once in "tour" mode. They will release in touring mode, as I learned - a rock took my ski off and it was a reasonable release (in "touring" mode!). The other release was also reasonable, not a pre-release, really. So I gained some confidence that the TLTs will actually release (for me) if needed, and they otherwise seemed to keep me on the skis; I was happy with that! On my quest for the lightest possible gear (an old guy who still wants to hike for powder), I am very close to the lightest rig possible with the Dynafit ONE boots, TLT bindings, and (probably) next year a pair of the new Rossi Spirit 7s in 180. Btw, I did NOT utilize the plastic piece under the boot; just omitted that unnecessary part... hope that's helpful! Let me know if you have questions....

      One of the best, if not the best

      • Familiarity: I've put it through the wringer

      It took me a while to narrow down on a touring binding that was just right for me. First I thought there must be a way to get a cheaper binding without compromising on my performance. However there are no other options that are as light and reputable as Dynafits. Sure G3 has options that are comparable but they don't come with the reliable name. I have only recently gotten into touring and have been very satisfied with my purchase. The adjustable heel risers are great and are easy to flip up and down with ski poles. If you want the best performance, lightest weight, and most reputable alpine touring binding on the market look no further! Or go with the Beast if you think your bad ass enough for it! That being said these are ideal for the skiier that tours alot and feels that every ounce counts in the backcountry.

      Excellent choice

      • Familiarity: I've put it through the wringer

      I have a bunch of days now on the latest version of the Dynafit TLT Radical FT12 binding. This alpine touring ski binding has proven to be the best performing binding for the backcountry that I?ve skied to date.

      Dynafit has made some improvements to this version which I really appreciate. First, the heel lifter system has been completely redone and is now a breeze to use. Instead of rotating the rear binding you now need only flip forward one or both of the riser pieces (depending on how high a rise you require) with a quick flick of the ski pole. This is quicker and easier than the previous system and can be done without any learning curve.

      Dynafit has also added a tab to the front binding piece to make entering the bindings easier. They call it a quick step in feature and it acts as a stop for your boot when clicking into the toe piece, making this action quicker and easier, especially for those new to ?tech? bindings.

      Finally, this binding comes with a carbon fiber plate which runs between the toe and heel pieces which features a lock mechanism. Unlocked, the ski maintains its natural flex, while in the lock position the ski stiffens up while increasing the torsional rigidity of the binding. This type of adjustability in the binding is something entirely new.

      With a DIN of up to 12 these bindings are not only super light and efficient on the skin track, they drive a big ski on steep terrain on the downs. I have skied these on 110mm underfoot skis in a variety of snow conditions and they were rock solid. I ski inbounds with these bindings as well and whether in the steep trees, making hero GS turns on the corduroy or moderately pounding some bumps, they have performed reliably and been bombproof. I have even chucked my much battered body off numerous terrain park features while attempting to keep up with 8 and 19 year old rippers. The bindings handled even the terrain park admirably, though I admit to not flying as high as the kids.

      Great lightweight binding

      • Familiarity: I've put it through the wringer

      have ski mountaineered some of the largest peaks in AK on this binding... it works as advertised... solid simple and mostly reliable... at -40F the plastic cone for swapping between heel positions broke... Dynafit sent me a new set of tops which I swapped out at home...minor issue when the binding has been bomber otherwise

      Light, sturdy and easy to use!

      • Familiarity: I've used it once or twice and have initial impressions

      I just mounted these on my Soul 7's with the 110 breaks, along with my cochise 90 boots with the tech sole inserts. Have taken them on one tour so far (up USA Bowl), and loved everything about these bindings. I definitely noticed how light they were on the skin up. It was literally the first time I have ever skinned faster than my friends. Lifting the heel risers with my poles was effortless. And importantly, they were very easy and highly intuitive to transition into downhill ski mode, and felt very good while making hard turns through trees. Overall, simply love these bindings. I was torn between the speed radicals and these, but I am glad I went with the Radical FT's. I really like having brakes, and I am confident that as I grow as a skiir that these bindings will keep up with me (with the 12 din range).

      Additionally, the bindings are very easy to switch from touring mode to ski mode WITHOUT having to take the skis off. You just step foward with your leg, bend your back knee, which raises your heel on your back leg, then reach and pivot the heel piece on your back leg until it is in ski mode. Then you step down with your heel and your back leg is now in ski mode. Repeat for the other leg. Now, taking your skins off without removing your skis, that takes a bit of practice but is definitely doable.

      Hi, I have a pair of Volkl 90eights I want to put a Dynafit binding on and was thinking of these. Not sure if the brake is too wide or would I be better off with the TLT Radical ST 100?
      I am 6'3" and 195lbs so I just want to be sure if I went with 4-10 din I wouldn't come out unexpectedly. I am generally grounded when skiing but will hit an occasional drop. I am an aggressive skier if this info helps. Thanks.

      So if you want to make it simple get the TLT Radical ST 100. Check out the link I attached about dins. Your din should be around 8 and the ST would work for you just fine. However if you want something beefier get the Radical FT with the 110mm brakes. They probably won't cause any problems but you can always bend or have the brakes bent in a little bit to keep them out of way.

      Can I mount these bindings without the baseplate? Also, are the brakes easy to bend to size if i have 115mm underfoot and go with the 110mm brakes?

      Duy L

      The Customer photos show above that you can mount these with out the base plate. Also bending the bindings is something that you can do. It works best with a ski pole (cut in half) and a little bit of heat. Be gentle with this process as I have had to do this is the past with a different binding and broke my fair share or brakes. Even then most shops can do this for you if you do not feel comfortable with it.

      can brakes be switch for swapping bindings between different width skis, or can the new 2.0's

      im thinkin the tlt's with the 130mm brake paired up to the blizzard Cochise 185cm ski's I weigh in at about 240. I prefer the shorter skis for the quickness in the backcountry any thoughts?

      James H

      You actually wouldn't need the 130 mm brake on those skis. I would go with the 110mm to ensure that the brake is not catching while skiing or skining.

      The ski length depends mostly. Were you are skiing. If you are skiing more narrow chutes and tight trees, a shorter ski should not be a problem. If you tend to ski more big line with fast wide open turns, a longer ski is going to give you more stability. Touring wise, either size will work great, this also depends on what the situation is around you(ie tight trees, wide open, long open flat areas...)

      Unanswered Question

      How would these work on the Black Diamond Current skis? The waist on the Current is only 87mm. Looking for a sturdy tech binding that works well inbounds as well as BC.

      Couldn't see a review for the Rad ST 2.0's. Have you heard much about their performance? I just bought a pair with a 120mm break to go on some Armada JJ 2.0’s (175cm / 110mm).
      I’m quite light (140lbs) and a good but not aggressive skier, so hoping I won’t be releasing at unexpected times in powder or on the downhill…

      Nick, dont worry about releasing unexpectedly. The new Radical 2.0's have gotten a more durable heel piece and a safer rotating toe piece which is how they got their binding DIN certified. If anything people will experience less pre-release than the previous models. I used the Radical FT and at 200 lbs I never pre-released even when skiing hard bumps, so I would only feel more comfortable on the new 2.0 version.

      Would this binding be a good fit for the Volkl Nanuq? Should I be concerned that the brake width is 110mm and the ski's width is 96 cm underfoot?

      Frank, these bindings would be great with the Nanuq except the brake width is too big. You really dont want to ever go more than 10mm in either direction for brake width. The 110 will work on the ski but, if you put them on a really high edge you run the risk of docking the brake and seriously tossing you around.

      How much do you weigh? Whats your current DIN set at? Could you get away with the ST version of this binding? That comes with a 92mm brake which would be perfect.

      My skis are 115 under foot, should I get some 110mm brakes and bend them slightly or go for the 130mm?


      i just get a pair of rossignol soul 7 and dynafit radical ft. the setup isnt mounted yet. i want to know if i align ski boot mid point (scarpa maestrale) and the mark in the souls 7. thanks a lot if anyone can answer me.

      Hey Sebasalonia,

      Where you mount the ski will be dependent on how you ski. For instance some people will go ahead of the recommended mounting line if they like having a slightly shorter tip. The traditional line will be best if you consider yourself a traditional skier who never skis switch.

      I would recommend measuring from the tip to the tail. Divide that length and it will give you the true center. Most people will prefer a mounting point somewhere between 3-7cm back from true center.

      Better yet, just take them to your local ski shop and have them mount them for you. Let the ski tech know your style of skiing and what you mainly plan to use the ski for. He will likely be able to recommend the best mounting point on that ski for the intended purpose.

      Best Answer


      Great binding and yes the brakes can be changed out from a 130mm to a 110mm. Recently spoke to a couple of buddies who absolutely love these and have used them in some extreme spots along with a few trips on Rainier this year. LIght weight and easy to change climbing modes along with entry and exit ease.

      Okay, so I have a question: I will be moving out west (CO I think) next season (currently skiing Stowe and Jay on east coast) and am looking to get an AT setup that will fit my needs...I am 6'2" and 190 lbs. I plan to be serious in the backcountry. By that I mean I plan to do long tours but I am a very aggressive skier (I love cliffs...20 ft, no big) I need a binding that can get me up the mountain efficiently but will hold up on the way down. I'm afraid the Dynafit won't hold up for the skiing I intend to do. I can't decide between a frame or a tech binding. I've been looking into the CAST system and it looks awesome but too new to say, google it if you haven't heard of it. Any suggestions?

      For reference I have never used any AT or tech binding. I want to know the difference in down hill capabilty between these bindings and something like the Marker F12. I have Armada Magic J's (126 waist) that I will be mounting an AT binding on. I know this is not ideal but with snow depths here routinly being 2' or more that is what I decided to go with. Will a dynafit binding be able to handle this wide of a ski on the down hill?

      Best Answer

      There is a persisting belief that the dynafit binding is great for the uphill but just a bit weak for the downhill. Well tell that to Eric Horjliefson. Before he co-created the Beast, he was bombing big mountain lines with Dynafit FT12s. Didn't hurt him any, so why should we mere mortals be concerned? I've been riding on dynafits inbounds, outbounds, resort bumps, etc. and never had a problem. Ski them, trust them.

      Also, they're far better for the up. Far, far better.

      I am looking to ski these with a Scarpa terminator X boot that is compatible with the TLT technology. Will these fit the sliding plate that comes with the boot for added rigidity? Should pop into the crampon straps.

      The description of these says they go from...

      The description of these says they go from DIN 5 to 12. Dynafits are not certified and therefore the release settings should not be described as DIN, but rather release value.

      If you're shopping for new touring bindings, it's good to be familiar with the difference between DIN and release value, you can find info by searching for the Dynafit FAQ.
