Description

Lighter and faster than ever.

Built to be light, fast, and super-simple to use, Dynafit designed its TLT Speed Radical Binding to withstand the forces of traditional alpine touring and maintain the low overall weight that ski-mountaineers demand.
  • A combination of forged aluminum, CrMo steel, stainless steel, and high-strength plastic provide plenty of strength and keep overall weight low (341g)
  • No plate under the toe means that power gets transferred to your ski more directly
  • Speed Step heel-height adjustment system activates easily using your pole tip
  • Slideable heel piece allows you to gain or lose 12.5mm of length without remounting
  • Torx (steel) screws save weight and are ultra durable
  • Guide leashes included

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.

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?

Cheers,
Jon

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.

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.

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 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?

As my second set of Dynafit radicals, all I can say is wow! I have these on a pair of 4frnt CRJ's and they crush powder at the resort and in the backcountry. I have no problem directing power to a fatter ski and the weight savings on these bindings are fantastic. If you want a touring binding that is easy on the uphill yet still delivers power, save the money and just pick up the speed Radical.

Does the stated weight include the leash?...

Does the stated weight include the leash? What is the weight of a pair of bindings no leash? Does the heel piece rotate to go from tour to ski mode?

Sandy Brown

I am not sure if the weight includes the leases. My guess is that it does not. Each leash weighs 35 grams.
Yes, the heel piece rotates to change modes. It will only rotate clockwise to prevent accidental auto-rotation.

I am looking at the Radical ST and Speed Radical - 5', 105 lbs, advanced intermediate alpine skier looking to leave my skinnier BC skis at home and try some of the steeper stuff on BD Syncras. The weight of the Speed Radicals is attractive. While some girls count calories, I count grams! Any advice on one over the other, or something completely different, especially considering I'm not an expert skier? Thanks! Oh, PS - long approaches!

Hi Marp,
The primary difference between the Speed and the ST is ski brakes. Personally, I opted for the Speed because Dynafits are notorious for having an aggressive ramp angle -- the height of the heel vs. the toe. If you go with the Speeds, you can optionally order an ST toe baseplate through Salewa to flatten out the crazy forward lean common to most of their bindings. If you're riding mostly backcountry with them, leashes are just fine.

I think you are fine with either, I have leashes on these and they work great. I don't usually lock the toe unless I'm in something super steep, and I've only had them release once or twice and I'm an aggressive 215 pounds.

Is there a maximum ski width recommended for these bindings? Does that hold for the older TLT Speed version?

Sandy Brown

Member since 
Groups:
Responded on

No specific max recommended, but I probably wouldn't use them on anything wider than 100mm. The Radical ST and FT have a wider and thicker plate under the toe which gives more beef for wide skis. Same goes for the older version, perhaps even more so as the toepiece itself is less beefy than the Radical series.

Yes. The crampon slot is the black bit at the back of the toepiece in the main photo.

Great lightweight touring setup for the Stoke as long as you won't miss having a brake. Mounting them is not a problem.

What's the $100 dollar difference between this binding and the other dynafit options?? Is it just a lower din setting or is this particular dynafit model less torsionally rigid?? I am an aggressive skier of 20+ years on a 96mm waist ski looking to do more touring and could really dig bindings that weigh in at 24oz!! I can handle taking a knee to change the climbing setting, but if this binding isn't going to deliver the juice I want to my edges.......... Any advise would be great y'all.

The RV value (not really a DIN technically) is the same as on the ST line but lower than that of the FT. The other thing you give up for the money are the brakes (vs. ST and FT) and the semi-rigid connector plate (of the FT) that adds some stiffness. But what you do get is a pretty significant weight savings making these a great option for a nice light touring setup.

There were some early in the season that shipped without that piece installed but Salewa USA (Dynafit distributor for NA) has been able to get them to folks if you contact them. (303) 444-0446

Looking at a used pair of TLTs mounted on skis. Heel is approx. 1" to far back. Is there a forward pressure setting, or can I just move heel ahead to the correct place ?

Sandy Brown

Member since 
Groups:
Responded on

Jim, 1" may be too far to move without remounting. The current TLT heelpieces have an adjustment range of 25mm, usually 12.5mm forward or back if mounted in the center of the range. Forward pressure is crucial to binding performance as tech system bindings do not have any elasticity. The correct forward pressure is measured by using a spacer slipped between the heel of the boot and the heel piece of the binding. Current TLT Verticals and Radicals use a 5.5mm spacer, current Low Tech Race & Low Tech Radical use a 4mm spacer. Older Dynafits also used a 4mm spacer.
Sorry for the long answer - Hope this helps!

Does Dynafit or an aftermarket manufacturer sell a brake for the TLT Speed Radical binding?

If you want brakes, go with the ST. The Speed is made for backcountry only.

I really like the new version of this binding. The height adjustment changes are significantly easier than the previous version. I also use the older TLT vertical and these are much easier to use. The new flip system to adjust the height is way easier than the twist with your pole version the older dynafit bindings use. Dunno about the taking off the binding to switch from ski to walk, both of my dynafits require me to take the binding off in order to switch from ski to walk. You can, however, switch from walk to ski without taking them off. After using them for half this touring season on my Armada JJ's I am very pleased over all. These are definitely more for touring than serious skiing and I would not recommend trying to huck or to ski very sketchy terrain as they will not hold as tightly as a traditional skiing binding.
