    The wait is over.

    The long awaited Dynafit TLT Radical ST 2.0 Binding makes its debut this winter carrying with it a safer and more efficient design, as well a well-earned TUV certification. While the easy-walking nature of traditional tech bindings may have been great on the uphill, they have left a lot to be desired on the descent, in terms of both power and safety—that is not the case with the TLT Radical ST 2.0 Binding. The pivoting toe piece of the Radical 2.0 is now able to absorb lateral impacts, giving the binding the ability resist early release. And if that wasn't enough, the heel piece now is capable of withstanding up to 10mm of forward pressure, giving it the ability to compensate for lateral impacts.

    Prior to the Radical 2.0, the Dynafit Beast 14 and 16 were the only bindings in the Dynafit lineup able to lay claim to TUV certification. The rigorous TUV certification ensures that release values of the bindings can be reliably set between 4-10 as determined by DIN ISO 13992 standards, resulting in increased safety and better downhill performance. In addition to the TUV certification, the Radical 2.0 now houses a more efficient design than it predecessors with a heel that can be turned either clockwise or counter clockwise—this means you won't have to waist time turning the heel a full 360-degrees just to get back to walk mode when you could be getting first tracks.

    They say if something isn't broke, don't fix it, which is why you'll find the same two-position heel elevators that were on previous versions of the Radical. Where the Radical 2.0 differs, however, is with the Easy Lock brake system, which allows the brake to be engaged or disengaged independently of the heel. Once the toe piece is moved into walk mode, the pivoting toe piece locks into place for the same easy-walking feel as previous Dynafit bindings. The toe piece is compatible with Dynafit ski crampons for added security when climbing icy skintracks and puckering ascents up bulletproof ice.

    Bullet proof!

    • Familiarity: I've put it through the wringer

    Skied these as hard as I have skied anything and they never let me down. 80% in-bounds hard charging and never released unless I needed them to but ripped it up in the woods and on Mount Washington with no complaints! Highly recommend these bindings!

    perfect for those who want it all

    • Familiarity: I've put it through the wringer

    Tested the dynafit radical 2.0 st in Chamonix this year. Perfect for the all mountain experience. Uphill, downhill, performs like dream. The pivot toe allows for a safer release and I didn't have any issues with early release. Easy to switch between touring and downhill mode. Dynafit finally figured it out!

    Mounted on Dynastar Mythic 97, 184 with some Salomon mtn lab boots.

    A+ Touring binding

      I split my time in the resort/backcountry about 50/50. Obviously these bindings have been great in the backcountry, but I have been very pleasantly surprised by how they have performed in the resort as well. I have them mounted on a pair of DPS Wailer 106's. Someday I will have a quiver of skis, but for now this rig serves me well in the resort as well as the backcountry.

      Great Buy

      • Familiarity: I gave it as a gift but have feedback to share

      Gave this as a gift to a good friend. She's very particular and a veteran skier. Took her a few rides to get used putting them on but once that muscle memory kicked in, she's been loving them ever since.

      Lightweight and Easy to Use!

      • Familiarity: I've used it several times

      I am very excited about my first tech binding purchase! I purchased the Radical ST's because I still wanted a binding with breaks if I ever ski them in-bounds, but also something that is lightweight for touring. These bindings are very easy to use! Switching from ski to tour mode is easy and dropping the 2 different heal elevator levels is easy, as well. I skied these in-bounds for the first time yesterday and I was impressed by their performance on groomers as well as in the backcountry. I will definitely recommend these bindings to anyone in the market for a tech binding.

      First Tech Binding

      • Familiarity: I've used it several times

      This is my First Tech binding, been Tele skiing for over 30 years. So yes, they are a bit more work changing over, but getting used to it. The rotating toes make it even a bit more difficult. That makes them more DIN certified, so I went with the Radical because i plan on using inbounds and sidecounty too. I liked the idea of being safer. Have yet to ride in the resorts to see how they compare to Alpine bindings. But happy so far

      First Tech Binding

      Awesome Binding for Touring!

      • Familiarity: I've put it through the wringer

      These are my first touring bindings and boy do they live up to their reputation!

      They're easy to get in and out of whether you're moving uphill or down. Locking in the toe piece for walking can feel tricky at first, but after a few times (and really, only a few times) it's easy peezy. The heel elevators are awesome with two settings for you to choose from, depending on the steepness of the terrain. When it comes time to ski down, a simple rotation of the heel and you're locked in to shred. I love the way these bindings ski and I don't feel like I'm sacrificing performance for a lightweight binding. Overall I would (and I have) recommended these bindings to anyone who tours!

      Awesome Binding for Touring!

      Great Lightweight Binding

        I have these on my touring specific skis and love them. I was worried about ease of use with the pin system (this was my first pin system binding), but found it fairly easy to learn and pretty intuitive for beginners. I haven't had any issues with releasing as I've known some friends to have with the older models. Great binding!

        Improved Design

        • Familiarity: I've used it several times

        Even though these are a bit heavier than previous generations, the improvements are totally worth it. The rotating toe piece is a great addition to the design! Locking the toe can be a little bit of a hassle if you don't practice with it before you go out on the mountain. Otherwise, couldn't be happier!

        Improved Radical

          I managed to crack the metal catch piece under the heel of my Radical 1.0's after a season, so I upgraded to these. So far so good. They are similar to the 1.0, but have been streamlined. When you click in the definitely feel more solid than the 1.0, but required you to ease up downward pressure slightly when trying to click in. Not a big deal, just something new to get used to. I like the pivoting toe when in ski mode and happily can ski in full lock mode when it matters most. I also prefer the turn/turn-back feature on the heel piece. Great product from a great company.

          A fabulous binding!

            I've toured in these bindings all winter and they have been great so far! Incredibly light, functional and reliable. A solid binding that is great for resort skiers that delve into backcountry as well. Easy to transition and pop into. An overall amazing binding!!

            Get Radical

            • Familiarity: I've used it several times

            Although these are a bit heavier than the original, by 5 ounces on the pair, from what I have seen, they function a lot better. The biggest issue with the original radicals that I noticed was how often they were prone to pre-releasing where after putting these to use several times, I have yet to do so.

            As a note and as others have stated, the rotating toe takes some getting used to, but as long as you secure it while touring up, you shouldn't have much of an issue. This same toe piece is a definite step up from the original radicals always well, providing a much more consistent release.

            Overall, these ski great. They feel a little beefier than the original model and have much less of a tendency to pre-release, definitely worth the extra 5 ounces!

            Great Binding

            • Familiarity: I've used it several times

            I love this binding so far! It is incredibly light, and great for touring. The climbing guides are super easy to maneuver with the end of your poles making for easy transitions while touring. In deep snow I really like how easily they tear through, they are so low profile that your binding is never grabbing the snow. The only issue I have had so far is a build up of mud in the pin holes of my boots that made it difficult to get into the bindings until that was cleared out. If I hadn't spent half a mile hiking in the mud this wouldn't have been an issue; but it did cause me to eject twice, mid-turn, while skiing because the pins weren't making full contact with my boots. Just an FYI!

            New is better

              this binding is great for a safe, well skiing backcountry tech binding. Heavier than the radical 1.0 but because of that I think it skis just a little bit better. The rotating toe is kinda freaky and takes some getting used to. The new heel risers are awesome and overall the new 2.0 is the way to go for a dynafit set up!

              Great Binding

              • Familiarity: I gave it as a gift but have feedback to share

              I gave these as a gift for a family member and the got the bindings at 120 mm (brake size) to fit my DPS 112 Wailer skis (112 at waist). They fit perfectly. The heel height adjustments are great (two different heights!) for steep slopes. Super easy to get into. I've read some reviews that concern the brakes, but you just have to make sure they're disengaged in uphill mode. Also read some reviews about skis popping off with these bindings and that has yet to happen! These are solid bindings, especially for uphill, but great for downhill too.

              Happy I upgraded to these

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

              Last year I started touring using Freeride Pro bindings, and they ended up not being a good fit for me. I switched to TLT ST 2.0s this year, and so far I really like them. Clipping the toe piece in is easier than I expected. Just remember to secure the toe piece when in walk mode, otherwise it will rotate, which is a great safety feature for ski mode (but makes walk mode awkward/humorous if you forget!). I got these in 105mm for my 102mm K2 skis, and I have Scarpa Shaka boots which have no problems clipping into the pins. I already feel like I have more control when I ski than I did with the Freerides. I'm glad I made the switch and I'm stoked Dynafit made the safety upgrades with the 2.0 model!

              Happy I upgraded to these

              There is the standard 25 mm adjustment in the heel piece on these bindings?

              I currently have the 120 of this binding and looking to buy a 106 size ski. Do you think this will be an issue?? Since you cant change the break i'm kinda in a bad position.

              Unanswered Question

              I bought a pair of these from backcountry a couple months ago and was able to try them out for the first time for a couple of runs up and down the mountain this weekend. The brake lock seemed to fail repeatedly on one binding while skinning up. I haven't had time to look at the mechanism closely, but I was wondering if this is a known issue, or maybe I'm doing something wrong? I can reengage it, but it's a very frustrating thing to happen on a steep traverse.

              I have a pair of atomic bent chetler, 123 underfoot. Im looking at Dynafit radical st vs. ft 2.0, any thoughts? Also, are they suitable for in bounds as well? Thx!

              If you are looking to use inbounds at all I would go FT as it is going to be better suited for resort abuse. The ST is a great touring binding but would not be my first choice for mixed resort/backcountry use. The FT is also going to drive those big skis a little better . If you are looking at this style of binding and picture yourself in the resort 30% or less the FT would fit the bill nicely. If you think you will be inbounds more than 30% I would go with the beast or kingpin.

              Can you tell me if this binding will fit the Black Diamond Quadrant boot? Thanks!

              What if I want to move the binding from one ski to a wider it possible to change the brake with the new radical? or not..

              For a 96mm waist ski, is the 90mm or 105mm brake best? Is that too far to bend the brake of the 90mm?

              what size brakes do I get with 94 mm waist ski?
              ie do I get the 90 mm and bend them
              or get the 105 mm and have a gap on the side

              Will these bindings work with 9523 standard AT boots, or are Dynafit TLT boots required?

              I have the K2 sidekicks - 108 underfoot. Can I go with the 105 brake and bend it or do I need to get the 120?

              Would the 120 brake work for a ski with a waist in the 100 - 105 range. I'd like the option to move them to something wider later on. Thanks
