My Chimera Unicorn Chaser with TLT Speed Rads and Phantom hard boot bindings.
What are the pros and cons of using a...
What are the pros and cons of using a Non-Dynafit Boot (but compatible) with dynafit bindings. Is the vertical heel gap a common problem? Scarpa's fit my feet better but I am weary of compatibility issues even though they have the tech fittings.
As long as you adjust the heel gap to 5.5mm you should be just fine. And as an added bonus Scarpa actually licences the tech inserts on their boots from Dynafit so you would be using Dynafit manufactured tech inserts with these Dynafit bindings!
I'm on a pair of Scarpa Maestrale and they work on all of my Dynafit binders.
The 5.5 mm is the horizontal heel gap between the back of the boot and the heel unit of the binding. I was referring to the sizable VERTICAL heel gap that knup posted between his scarpa F1s and the ski. Its my understanding that is normal. Also just got a pair of Mobe and radical ST's, they work great together! The boot fits snug right up against the power towers! Super pumped...I am surprised most people mainly talk about what skis they are matching with their dynafit bindings when I believe a more important consideration is which boot/binding combo you choose. Really all three should work together for a specific purpose i.e. lightweight mountaineering, backcountry powder, multiday tours...etc.
Hi, Ive got the same concern as knup119808...
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.
If the misalignment is enough that you cannot easily step into the binding it may have been mounted incorrectly. I would take it back to whoever mounted it for an alignment check. The heel gap on all Radical series bindings should be 5.5mm.
Entry level tech binding?
- Familiarity: I've put it through the wringer
But don't be fooled. Lowest ramp angle, short of a race binding and the Radical toe is no short cut. Easy fit for several pairs of boots with the adjustment in the heel. Good for the first time BC skier or on your favorite pair of sticks. This is a great binding.
Nice binding on or off piste
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?
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.
The binding to get
- Familiarity: I've put it through the wringer
I have this binding on all of my touring skis, fat and skinny. The Radical toe piece has a wider mount pattern so it works well with fat skis and the heel piece is a stripped down version of the ST. The heel is still adjustable to accomodate different boot sole lengths. It's got the best features of the FT and ST but in a stripped down lighter package. You cant put a brake on it that's why it comes with leashes.

got some black diamond push 175mm 4 buckle tele boot- any of these dynafit binding fit em? looking for alpine 80 percent of time carving crud pp, ice. would like the flexibility for shlepping fence gates etc. also tele boot comfortable and WARM... hmmm
Unfortunately those Black Diamond Push boots are not compatible with a tech binding so Dynafit is pretty much out of the question.
Hey Sandy, you said "The Radical ST and...
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?
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...
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.
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.
Go Dynafit. You won't regret the drop in weight.
any idea when these will be back in...
any idea when these will be back in stock?
We have a couple dozen on order and we expect to see them in stock sometime in October. That's the best ballpark I can give you at this time, its really a matter of how fast Dynafit can get these to us.

Dynafit TLT Speed Radical In Action
Getting better, but still not perfect
I have used many versions of Dynafit bindings as was hoping that this was the one. I really do like the improved toe piece as it is definitely easier to get into the binding. The heel piece is also improved and it is so easy to change the heel height. With my old Dynafit bindings, I used to stay in a height setting longer, but now they made it such a breeze to change up and down. Lastly, these really hold up to fat skis as I ski on 107 underfoot.
Here is the one downfall. Dynafit says that the heel piece will only rotate clockwise to prevent accidental rotation into ski mode. However, I find that on steep, icy slopes I still find the heel piece rotates into ski mode just as much as previous models.
Space between ski and boot
Hi. I hope someone can tell me if this looks to be correct or not...
There's a lot of space between my skies and Scarpa F1 boots.
Is there something I could mount on my ski to make the boot sit more stable.
I just got a pair of the speed...
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?
There is a small screw that moves an arrow indicator for the one DIN setting and the big screw in the rear housing adjusts the other DIN and that you just line up the end of the screw with the DIN hash marks on the side.
here is a link, with pictures on how to adjust the "big screw" for different settings. This large screw adjusts the lateral release.
I highlight the raised plastic marks with a sharpie black marker. Easier to see them
Hanging tough on fat skis
- Gender: Male
- Familiarity: I've put it through the wringer
I put these on my new DPS Lotus 120s. Many people warned me about dynafits on fat skis, but at 215 pounds and a very aggressive off-piste skier I've put these through the ringer with nothing but good experience. They are light elegant in design and well made. I'll get another pair for my next set of skis.
Not missing my Vertical ST's
- Gender: Male
- Familiarity: I've put it through the wringer
Im loving the new toe and heal. First off, I got these after using the older ST without brakes. Put brakes on those and decided I'd rather have leashes. Improvements over the vertical st and tlt classic are many. First the toe is an improvement over the old one in every way. It's easier to step into, more stable with the power towers. Mounting with four torx screws instead of 5 posidrive bits, etc. But for me the best change is the heal. Now if you don't change your heal height while touring very much you probably won't care so much, but for those of us that do the new heal elevator setup is worlds faster than the old one. With a little practice I can now change height without hardly stopping. Also because you don't have the leverage of a ski pole sticking into the binding to possible break the heal piece off(rare I know). If these fail you still have the flat touring mode and downhill mode, if you were to get over zealous with the old setup you could break the entire heal unit leaving you with no downhill mode.
The leashes that come with these are a little nicer than the old ones since they had a tendency to come apart while skinning from time to time. These new leashes can't do that since there isn't the old tooled connector in the middle(though I did miss the old built in screwdriver when I went in my first tour without setting the din up from 4). Say you change your mind and want brakes, just but a radical st heal plate for $80 and you have a pseudo radical st.
Only downside I've encountered is when you forget to switch the heal for downhill during transition and then stepping in, realizing you have to do it by hand instead of use your pole. That is being really nit picky.
Overall I think this is the sweetspot for dynafit bindings. All the advantages of the new radical toe and heal with none of the weight gain and cheaper to boot.

I'm lovin these! I have them mounted on a pair of Black Diamond Drift skis - not a skinny option and they work great. I sport them on and off piste and couldn't be happier. New toe piece tabs make stepping in even easier. Lock mechanism feels solid. The heel piece is easy to rotate and elevators can be flicked into position with a pole. I ditched the leash but it works well and doesn't flop around in the way. If you are >50% backcountry, this is the binding for you.
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.
