    Perfect backcountry binding!

    • Familiarity:I've put it through the wringer

    These are my favorite BC binding. Perfect balance of weight, downhill performance, and cost = value. They are simple, easy to use, and maintain. Great companion for the BD Carbon Convert and TLT 6's. Super competent BC combo!

    light and strong

    • Familiarity:I've put it through the wringer

    Love this binding, I have had many pairs of previous dynafit bindings but this is the best so far. Updates to the heel lifts are great, they do take a little getting used to, but once you do, its great. Haven't had any issues with pre-releasing. Very light weight

    So light and strong!

    • Familiarity:I've put it through the wringer

    This is my go to touring binding for more technical missions here in the PNW. If you're doing lots of miles and technical descents this is a great option. I have never had a pre-release issue or any other wear related issues and have skied these a fair amount in the backcountry with lots of skinning. My version has the anti-rotation solve from dynafit which IMO 100% solved the problem of the binding accidentally rotating while skinning. The toe is super easy to step into, some people are a little scared the first time to go brakeless but once you do and lose the extra 2-300 grams you'll never look back. My only complaint with this binding is that the ramp angle you get out of the box is too steep for me. This is the same toe unit as the dynafit ST but doesn't have the plastic base plate that would help lessen this ramp angle. I went and bought the ST plastic base plate and had this mounted underneath my toe pieces and this significantly helped reduce the ramp angle and make the bindings have more of a traditional alpine binding angle which is more comfortable for me to ski. Just make sure you also get longer screws for your toe piece if you plan to do this mod.



    Overall, very impressed with this binding. If you're going to be doing long tours and need a reliable binding that is time-tested and issue free, give this guy a shot. Since it is an option that has been around for a few years you can often find deep sales on this option, so very economical. I have the binding on K2 Waybacks and Black Diamond Currents.

    So light and strong!

    Should have gone to breakless years ago

    • Familiarity:I've put it through the wringer

    Really enjoying the breakless TLT Sped Radicals. Despite the weight, these bindings are still way burly than people give them credit. Cutting out the breaks from the equation sheds a little extra and this really adds up over hours and hours on the mountain. I'll never go back to breaks again!

    Need for Speed.

    • Familiarity:I've used it several times

    Dynafit's TLT Speed Radical Binding is unlike any other binding I've ever skied with. This thing is surprisingly secure and performance-driven for how light it is. As my first pair of tech bindings, I'm amazed every time I clip into these beauties. My toe has yet to come off on the skin up, and I believe all the other skiers who commented negatively on this product forgot to crank the latch in front of each toe piece. I love the heel piece's innovative construction that's easy to use, adjust the heel risers, and click in. I've only lost my skis on the downhill once so far, and it was totally worth it. In an avy class, an instructor recommended not attaching the leashes in case an avalanche takes me down with the skis. What do you guys think of that?

    Need for Speed.

    Solid and light

    • Familiarity:I've put it through the wringer

    Great AT binder. I am a former ski racer, I go downhill fast, and I have never had a problem with these guys pre-releasing, even on high-teton death crunch. They go uphill stupid fast and the climbing bars are very easy to use.



    My only complaint is that the heel piece is not multi-directional like the old heels. Because of ice build-up I often have to turn the heel back the way it says not to, and I have no idea how bad this is for the binder. However it looks like this years model has a little block that prevents turning back that way. Otherwise, great binder.

    Dynafit tends to make small changes without really telling anybody, and this has been chronicled extensively on Wildsnow.

    Depending on which heel piece you have, the "TURN" arrow may either shear a pin (pretty unlikely because the ones that had this are decently old) or mean nothing at all (the new ones).

    Easy way to check: back off the screw for the heel release, remove the spring and the cap, and pop the whole heel top assembly free. If there's a small metal pin in the bottom, then try to follow the arrow. If not, then spin however you want.

    Do not use with Scarpa TX Pro Boots

    • Familiarity:I've used it several times

    I bought these as my first Alpine binding. I'm a tele skier that recently converted to NTN. Given that Scarpa's TX Pro is tech binding compatible I figured I would attempt to use this ridiculously light set up for back country tours. I was not impressed.



    I used the spacer provided by Scarpa and even had Scarpa send me a different sized spacer but despite this I was auto ejecting all over the place.



    I used them once in bounds and once on a tour. In wet snow the rear tower would ice up and be difficult to rotate back into ski mode. Also, the spacer (the hockey puck looking thing that goes in the crampon slot) really needs to be removed during all tours because mine had a tendency to fall out on its own.



    Being a former cable binding guy, trying to stay super light and handle stepping in without brakes should have been a no brainer. Well I sucked at it. Maybe getting used to Dynafit bindings takes time, but it was much harder than expected.



    The big kicker, and the reason I had to return them, was the fact that going over the smallest rollers would cause me to pop out of my skis. I think this is because the boot is flexing against the bellows because of the spacer underneath. If you notice, the TLT Speed Radical's toe binding is NOT mounted on top of a black spacer (that you get with the TLT Radical ST). Take a look at the photos and you'll see what I mean. The front of the TLT Radical ST is about 4 mm taller than the speed radical. My friend recently got the TLT Radical ST and uses it with his Scarpa TX Pros and has no issues. I believe this is because the included spacer works appropriately with the binding at this slightly elevated height. You might suggest skiing without the spacer if it is causing the boot to pop out of the bindings. Well then in powerful turns the sole length will shorten because of the flex of the bellows.



    If you don't believe me, watch the included video I shot demonstrating two of the problems. I was so frustrated with popping out of my skis while just going down some groomers that I decided I would ski in tour mode and 'lock my toe down.' Despite this step, I was still popping out. You'll notice that the right boot won't stay in tour mode (because of ice getting under the binding, another problem that limits the use of this binding). The left boot easily locks into tour mode. Then I do a little bounce test just standing in place, not much force at all, and whoops...ski comes off. The right ski also popped off but you can't tell that in the video.



    In the end, I'm sure this binding rocks if you have the right boots but DO NOT PURCHASE IT if you're trying to use it with tele boots with tech inserts. Go with the TLT Radical ST or another tech binding. I would have given this one star if it wasn't for the incredible light weight that still made this thing a joy to skin with. I felt like I was cheating.

    Yikes. Sounds like you had one hell of a go at it.

    About the Radical ST shim: it is included because the heel tower is higher on the ST (and FT) because they have to accommodate the brakes sliding on to the heel post. If they did not shim the toe, the delta angle between the heel pins and toe pins would be pretty steep.

    Your issue was probably exacerbated by the lack of any forward pressure spring on the Speed Radical, as you were relying on only the tolerance of the pins to deal with both boot and ski flex.

    Both Dynafit and G3 (with the Ion) have seen to fix this somewhat in their more recent offerings, but not in the Speed Radical. I'd be curious how other bellowed boots (like an old Scarpa F1) would do.

    If your a mountaineer - Do NOT buy these

    • Familiarity:I've used it several times

    Got these thinking they were the business. I was to become roadrunner in the mountains. However on aproaching steepish slopes ascending hard snow (20-30 degrees) the bindings would automatically release leaving me in some bloody precarious positions. This was with the DIN set to max. This happened in excess of 10 times over a day - By the end I was ready to throw them in the bin. Im pretty chilled most of the time but these failed to impress me and are bloody dangerous if your in no slide zones and you ski hits the eject lever !!

    Ben did you happen to lock your toes per the Dynafit recommendations while touring? This will most certainly happen if you simply step in and start touring. I've yet to come out of mine while touring in "tour" aka lock mode. Another issue that can arise is if there is too much snow under the toe. You wont get a positive pin placement and can prematurely step out.



    I also ski with them in this mode for no fall lines. As long as your ski doesn't over-flex you will be all set.

    As with Ryan Gibbs - I am almost certain the reason you encountered this problem was because the toe pieces were not locked in (i.e. - you pull up on the toe piece tab until it clicks all the way up) - especially if this happened to both bindings - if it were one doing it, and you were locked in, then I would say there is a malfunction but if it was both - probably the lock function.



    The first time out I only clicked into them and totally spaced locking them in, and as you said, I was touring on hard snow and they popped out. I immediately locked em in and for the rest of the day I was busting hard kick turns on ice and feeling like a wizard.



    Try locking em in - then come back and we'll figure out whats going on here!

    ALso make sure there is no ice in the toepiece of your boot.

    I was having problems popping out on the skin track and growing increasingly frustrated until I discovered the cavities in my toepiece where the pins lock were crusted with tiny shards of ice. Cleaning it out with a multitool did the trick and I no longer had any issues. This is especially an issue with wetter snow when air temps are really cold.

    What's the difference between going to Shralptown USA and being tired and sad? - Not having the winged dynafit snowleopard strapped to your boots.



    True, Time, and tested - these things are so simply light and efficient it makes it hard to want to really ski alpine bindings again.



    The ability to have some room for boot adjustment has allowed me to move to a different shell size without the worry of remounting.



    I've done a bit of personal product testing on these by hitting decent size airs, sub 10 feet, and have come out on top each time.



    And going to town on some hard, chalky snow makes these things legendary.



    Dyna. Fit.

    Simple and Reliable

    • Familiarity:I've put it through the wringer

    I've been riding the Speed Radicals all year from Chamonix, to Canada, and a tone of time in the Tetons. They have yet to fail me. To me, brakes just get in the way often, plus in Pow they won't really stop much anyways. Just adapt your clicking-in routine, when sketchy I hold the ski with one hand and click in at the same time.



    These binders are super light and love the uphill, but will hold their own on the down. Keep your weight over the ski and there won't be any problems.



    The only mod I like is to add a lift under the toe. The ramp angle is set heel high, but I find more comfort with flat ramp angle.

    Fast and Light

    • Familiarity:I've put it through the wringer

    The TLT Speed Radical is a great binding for backcountry skiers looking for something lightweight and great quality. I'm 6'4 and 210lbs, and these bindings work well for me. That being said, I've popped out a couple times when I shouldn't have. I love these because of their weight, but I'd go with something different if I wanted power. The leash takes a little getting used to if you're used to a brake, but I prefer them now. Bottom line, great binding for the majority of backcountry skiers.

    I don't need no stinking brakes

      It's amazing, I always say I need brakes with my fatty skis, you know in case they come off when I am pushing my boundaries and skiing hard... But every time I have only had brakes on my Fatty skis (125mm through 98mm) when I lose a ski and it's pointed downhill in powder I witness the efficiency of today's powder skis, when I see it rocketing off below... They just float up and best I can tell is I think those little brakes seeming are for show for the resorts... So the only thing that really works is leashes... Why waste the weight on a powder ski... The radical speed is all you need...

      Great!

      • Familiarity:I've put it through the wringer

      Climb great, ski great. Was worried at first that I would miss having brakes, but I definitely don't. I'd highly recommend the B&D ski leashes with these.



      Depending on your boot's fitting, it may be very difficult to lock the bindings into tour mode until the parts break in (although maybe this has been fixed in later versions). If your boot pops out, you probably aren't locked in, crank on that lever!

      Hi. So do these have the TUV certification talked about in the article (about buying AT bindings)? Would they release properly for a 105lb gal?

      shanmtb,

      These do not hold a TUV certification. Check out the new Radical ST 2.0. It's a little heavier than the Speed Radical, but it's TUV-certified and comes with brakes.

      http://www.backcountry.com/dynafit-tlt-radical-st-2-binding?s=a



      If you are looking for the lightest option that still has a heel release, the TLT Speed Radical is still a great choice–in my experience, they release just fine if everything is properly set.

      Best Answer

      I weigh 125lb and I have my DIN set at around 4. The bindings end up turning themselves out if I don't increase my DIN past 4. I leave it at a 4 because I don't mind it too much - It just means that I have to keep an eye on my settings and turn it back in every once in a while. Not sure if this will affect you, but it's something to consider.

      So Kristin, what do you mean by "turning themselves out"? Does the setting migrate higher with use? Have you released out when you expected to? Or failed to when you wanted? This will be my first AT set-up and I want it to be safe (as possible!) Thanks so much for your input!

      Are the Speed Radical bindings you have in stock all the updated models with the added anti-rotation device in the heel?
      "Update: All Speed Radicals now come with an anti-rotation mechanism that is mounted under the heel to prevent accidentally going into ski mode while skinning."

      Hi, I have a pair of radicals but don't...

      Hi, I have a pair of radicals but don't want to be leashed in if caught in a avalanche. Also they can be dicey to put on when on a steep slope. Can I add brakes to the radicals?

      Best Answer

      You cannot add brakes, and yes they can be dicey to put on when on a steep slope. A tactic I have been using is this: I lay them down on the snow and clip them into my boot. Get both skis on, then just clip the leash back to themselves once I get them on my feet. To be honest though I havent even used my leashes in a year. I do get scared but, when I am on a steep slope I am sure to chop a good step and never let my hand leave the ski and always put on the downhill ski first as it gives you more stability to stand and get your uphill on. I recently had to go to a skimo race and they made us use these like dinky cordage leashes with non-climbing mini biners, those would definitely tear away in an avalanche. Maybe the leash that comes with these are just a bit beefy use something with a breaking force of 200lbs.

      Is this enough binding to power a 120 mm...

      Is this enough binding to power a 120 mm wide BD Carbon Megawatt? I pretty much only use these skis for BC in Powder.

      I have that exact set up. Since you'll be skiing the megawatts in powder...power from boot to ski isn't an issue. And, in reality, the binding is the least of your issues. Running a softer boot with a giant ski may provide some "lack of power" before the binding will. That said, I ski the 188cm megawatt with TLT6 boots and they shred.

      Does anyone know... what am I really gaining...

      Does anyone know... what am I really gaining with the Plum Guide vs. the tried and true Dynafit Speed Radical? I'm having a really hard time justifying the additional $$ for the Plum bindings...

      Once dynafit's patent expired, several manufactures were able to join tech binding industry. Plum was one of these companies. Plum has essentially taken a really good dynafit product and has tried to make lighter, stronger, and more reliable. Wildsnow has a good comparison between the Guide and Speed binding. I don't have Plums, but I hear good things. One downside is that I have heard that customer support in the states for Plum bindings is nonexistent.

      Confused between the Speed Radical and...

      Confused between the Speed Radical and Radical ST. Are the brakes on the ST interchangable? If I change to a wider ski in the future, can I get wider brakes? If so, how much do they cost? (I don't see brakes only listed on BC.com). Can you take the brakes off, and use a leash instead? If you can't swap the brakes, seems like I'd be better off with the Speed.

      Best Answer

      This years Radical ST and FT cannot have their brakes swapped after they are mounted without pulling off the entire heel piece and remounting. So basically if you need brakes and know what width you need then go with the ST. If you are ok being brakeless and just using a leash, you can save the weight and some cash and get the Speeds.

      How would this bad boy stack up if I wanted...

      How would this bad boy stack up if I wanted to go hard (no terrain parks really, maybe occasional small jumps) in a resort setting? I want one ski that does it all AT and Resort stuff.

      You will likely need to wear the leashes with these since most resorts require some sort of ski retention device. That being said I think they may get you by for the occasional resort day but I'd be wary on jumps and going really hard. One of the downsides of the these and most tech bindings is the lack of elasticity so you may find your self ejecting prematurely on harder hits.

      Hi, Ive got the same concern as knup119808 with the space between my boot heel and my ski. Also my heel tech inserts don't line up quite right with the binding, how concerned should I be? These are my first pair of proper touring bindings so I'm not too sure what to expect.

      I own a pair of radical st bindings and...

      I own a pair of radical st bindings and looking for an additional pair. I like the idea here of less money and less weight with equivalent performance. My biggest concern is safety being attached to the ski. Say I take a gnarly crash or in avalanche (using abs backpack) would the skis be dangerous flying around me. In an avalanche I would assume they would act like an anchor attached to my feet. What if they hit my head and knock me out? What if they cut my blow up?



      Second concern is rear plate seems narrower than the st, and I am going to mount on 110 wide skis. I am 135lbs and the skis have thick wood so plenty to bite to. Could this be a problem?

      Best Answer

      To mitigate the risk of the skis being an anchor in an avalanche I clip the leases to breakaway loops that I tied with 2mm cord (I believe) rather than the little steel loop that is pictured. So in a major crash or slide the leashes should break the cord loops and you are good to go. As for heel piece it is the same mount as the ST so there isn't any more or less there in terms of screws. The difference is of course the heel piece of the ST is a bit differently molded in order to have a brake attached to it.

      I want these but compared to the st still makes me think penny wise pound foolish, literally. So when I look up the 2mil cord the tensile strength is anywhere from 40lbs to 200lbs, so where do I draw the line? Even if I pick 60lbs, do I still want that ski around me before it breaks? I almost think a good solution is a long retracable extendable leash (only in bc).



      Don't know if you answered my question. It seems the screws are closer to the centerline (long ski length line) therefore less torsional strength.

      The heel screws are in the same place for the Speed and the ST. I switched my bindings from the ST to the Speed and was able to reuse the holes (http://www.wildsnow.com/backcountry-ski-pdfs/dynafit-template.pdf) You can also check against that template. As for the leashes I guess it's really a matter of preference and conditions. I have no empirical knowledge as to the force generated by an avalanche that is deep/strong enough to suck skis down but I would imagine it exceed 60lbs easily. The only slide I have been involved with was only deep enough to run over my parties boot cuffs but it ended up still bending my partners ski pole in half (alum pole) so who knows. Then there are of course the situations where you are picking between two bad options. Anchored and buried or lose a ski and die anyway... Lot to consider for sure.

      Ben, a small nor cal shop called bndskigear.com makes long leashes with break away tabs for just this purpose. A nice side benefit is you can keep them attached while ripping skins in sketchy spots and have the peace of mind that you're not going to lose your ski. FWIW, I've tried the multiple zip tie method of creating a breakaway leash with the OEM radical leashes and it didn't work too well. Took a digger at the resort and the windmilling of the skis on a short leash was enough to break the zip tie. Sketchy. If you go with a breakaway option, be sure to test it! Good luck. (Awesome binding, BTW)

      Hey Sandy, you said "The Radical ST and FT have a wider and thicker plate under the toe which gives more beef for wide skis."

      Is it possible to add this plate to the speeds? How would this affect the ramp angle of the bindings?

      Also, what is the difference in stack height and ramp between the speeds and the STs?

      Thanks

      Best Answer

      The FT and ST have risers under the toe because the heel is higher due to brakes. These are plenty beef for the widest skis. I have them on K2 Darksides and DPS Lotus 120. Most folks have problems with ripping bindings off skis because of bad mounts. Don't use a power drill to set the screws, hand tighten, then you wont weaken the core

      Yes, I used the plates on my Speed Radicals specifically to lower the ramp angle. Just make sure to use the longer screws. Works great. Difference between bindings is substantial. More here:

      I'm thinking of putting a pair of these on my 10/11 Gotamas (currently mounted with Barons). They are heavy! Should I dyno the Goats or save up for lighter skis + dynafits? East Coast, mostly day trips, aggressive skier, and hit drops around 10ft. This will be my 2nd season in the backcountry.

      Thanks!

      Allen

      If you are an aggressive skier and hit drops I would look into the G3 onyx binding. I've had it for 3 years and never had a problem. I have heard of dynafits blowing up if you rally them too hard. The g3's are a bit heavier but no where near as heavy as barons. As far as getting lighter skis goes, you will never regret that!

      Thanks Matt, glad to hear the Onyx is working well on your setup. I'm a bit concerned with durability of the Onyx, but the Speeds have also had issues! Twice the weight, although I like the DIN and ability to switch into ski mode.

      Hi all,

      I just got a pair of the speed radicals but I can't figure out how to adjust the lateral din release for the heel. I know how to turn the big screw but there are no notches or marks on the screw to indicate how to line it up to the din marks. Do you screw it all the way and then back it out to line up the screw driver slot? Or am I really missing something?

      I am looking to get some dynafit bindings...

      I am looking to get some dynafit bindings to go on some Rossi S7's 188cm. I am 6' and about 160 lbs. will this binding be enough to power this ski both inbounds and out? I don't huck cliffs or charge moguls, but ski pretty aggressively otherwise. Thanks!

      Jeff, For both the skis you are on and your skiing style, I would lean toward the Radical FT first or the Vertical FT, second. Both have a higher DIN. The Radical FT also is beefier, has a wider connection to the ski and has more torsional rigidity.

      Thank you for the info. I would love to get either ft binding but I'd really like to only spend $400 or so on these. Will the speeds hold up or will I be disappointed? Would the vertical tlt st binding be worth the extra $50 in my case? Or do those ski about the same?

      Speed will do fine. I use them in a similar situation and am heavier/bigger. Just buy the Dynafit spacer to go under the Speed toe for best effet but not required. Plate lowers ramp angle and gives you more support. Be sure to do it with the longer mounting screws though. I've skied 190cms x115mm both with and with out on lift and off..no problems.
