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

Here's what others have to say...

Are these binding compatible with Black Diamond Quadrant AT boots?

Responded on

Yes! These bindings are rad. Almost feel like I'm on alpine bindings.

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...

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.

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.

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.

Will these fit any boot or do you need to...

Will these fit any boot or do you need to buy a specific binding for a given boot size? I have pretty average feet around 9 or 10 and am considering getting these while they are on sale but have not bought the boots I would use yet.

I have Atomic Access 181's 100mm. I'm guessing I want a 110mm break, yes?

Responded on

Hey Benji,

You are correct. The ideal fit of a ski brake should be the same width or no more than 15 mm wider than the ski width.

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!

Can the brakes be changed? Meaning if I...

Can the brakes be changed? Meaning if I get the 130mm can I swap out a 110mm break at a later date if I move to a narrower ski?

Best Answer Responded on

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.
Enjoy em!!!

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....

Hey guys, noticed that the Radical FT is currently cheaper than the ST. I am a lightweight skier who is not overly aggressive, so I don't think I need the baseplate. If I order the FT, can I remove or take off the baseplate?

The toe piece has multiple interim positions - I get that it should be fully up when in tour mode, but can someone explain the various positions?

Best Answer Responded on

The interim positions are just the binding ratcheting as it adjusts. There are only two settings, walk mode and ski mode, and you should move the toe piece all the way up, or all the way down when switching between walk and ski mode.

Responded on

Mystery solved, thanks. Everybody I know skis them in the locked touring mode.....but did not have your answer.

One of the best, if not the best

  • Gender: Male
  • 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.

Am thinking of getting these with coomback...

Am thinking of getting these with coomback skis in near future. Do you mount them and if so how much will that be?

Responded on

We are able to mount the Dynafit TLT Radical FT Binding in our shop for pick up, but we are not able to mount and ship them.

To clarify, our shop (or retail store) is located in Salt Lake City, Utah. If you are a local, we've definitely got you covered!

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
