Description

The name might be straight from the '80s, but the tech is definitely 21st century.

Designed with a 100mm brake and gliding heel plate for improved releasability, the Dynafit TLT Radical ST Binding excels at backcountry touring and ski-mountaineering adventures.
  • A combination of forged aluminum, CrMo steel, stainless steel, and high-strength plastic provides plenty of strength while keeping overall weight low (531g)
  • The six-millimeter plate under the toe aids turnability without sacrificing power transfer
  • Self-guiding wings allow for quick entry

Want to get a couple of Dynafit Radical STs when they become available, to fit a couple of pairs of Dynafit Huascaran skis. One pair (167) is 110 mm underfoot, so I assume the 110 mm binding will fit perfectly. But what about a 186 Huascaran, with 114 underfoot? Can the 110 mm binding be bent, or should I go with the 130 mm binding? Thanks.

I have those same skis and went with the 130mm, it fits just fine with very little overhang. You will love that set up! Check out my review.

When a muckup at my shop left me with a pair of twice miss-drilled tele skis and no chance of getting my skis replaced, I was forced to reconsider my binding choice. I waffled between the Barons and these before ultimately going dynafit. Let me say that each time I use them, I like them more and more, to the extent that I'm thinking about shelling out again to stick on my Line Pandora's.

I've been using them on a pair of Black Diamond Embers (95cm underfoot) all season, frontside, side side, and backcountry with great success. The first few days I was on them, I had to get over the fact that it felt like I didn't have bindings. Once I got my brain wrapped around how goddamn light they were, life was OK. I was originally leery about ejecting from the bindings, but it was pointed out that I weigh 120lbs soaking wet and would probably not have that problem.

Pros:
Lightweight, minimal and elegant
Pivot point at the tips of the toes instead of in front of the boot (like Barons)
Burly - the only times I've felt close to spontaneously ejecting was when I was getting close to the limit of what I could do with the skis
Can adjust heel elevators without having to twist the heel (as you had to on older models)

Cons:
Price, but I was willing to suck it up and am glad that I did.

I'm considering getting a pair of Radical ST 110mm to mount on K2 Backdrops (112mm underfoot). I'm assuming that little difference is no big deal to bend out... is that correct? It seems like overkill to step up to 130mm.

Yeah I'd go with the 110s, I've bent these 2mm no problem, and on the flip side I've had teh 130mm on some 110s and the overhang was noticeable while skiing but more so while skinning (the brakes were catching on each other occasionally).

I've just purchased a set of 108 under foot ski's, am planing on set of 118 underfoot.... will the 130 brake work for both, or am I better off using powder straps?

Hey tim4515806,

On the 118mm waisted ski, you'll be fine with the 130mm brake version of the Dynafit TLT Radical ST Binding. The 108mm waisted ski on the other hand will work fine for stopping, but may not fold up enough when in alpine mode and descending.

The brake does fold inward more than other alpine bindings, but 22mm is quite a bit of distance out there.

These are fantastic touring bindings. They are extremely lightweight, easy to get in and out of on steep, potentially treacherous terrain (once you have some practice) and they are solid on the slopes. I feel completely sturdy and secure in the binders in deep powd, on steep bumps and in heavy crud.
I'm riding 181 Surface Live Life's with a 110mm waist and I have no trouble at all controlling the skis with these binders.
Like the previous reviewer, my one and complaint is the brakes.
If you are on steep, hard snow, i.e. anything but very soft and deep powd, don't expect these brakes to stop your big fatty boards from taking off down the mountain.
The one and only time these bad boys came off was when I hit a rock HARD, right under foot, on the outside edge, in the apex of a turn, while skiing fast. The bindings did their job and release when they should have, but then things went downhill from there... literally. My ski took off like a bolt. Luckily I was in somewhat remote terrain where there weren't a lot of other skiers.
I found the ski about 400 yards downhill but it was only because it hit a small tree top that was sticking through the snow and got hung-up. If that hadn't happen I'd be out a $500 pair of skis and a $500 pair of bindings, not to mention the potential liability of hitting someone with my runaway ski.
A friend of mine had a nearly identical experience.
The shop contacted DynaFit who reported no similar complaints. I talked to Surface about it too and they said the same thing. The universal consensus seemed to be: "Ski brakes are no guarantee against runaway skis."
Fair enough.
However, I think it's valuable information to have ahead of time. The brakes on these skis sit back at an angle that doesn't give them much purchase. Check out the photo compared to the brakes on my Marker Barons.
I looked into modifying the brakes but that may be a lengthy off-season project.
Otherwise, I LOVE this bindings. They tour like a dream.

Light, nimble but don't let 'em fall off

Similar to other reviewers I was previously skiing the Marker Barons before I switched to the Dynafit Radicals. I had two seasons on the Barons with a handful of backcountry days but wanted something lighter and better suited to long tours. I put these on my 178 Volkl Kikus (107" underfoot) and they ski great. I love the feeling of being closer to the surface of the ski. The Barons were like Cadillacs on my feet but I was raised +1" above the surface of the ski. The Dynafits lock me in right at the ski surface which gives me an amazing amount of control. Slight movements engage the edges without having to really dig in and I feel comfortable going FAST! The din is easy to adjust and I love the multiple settings on the toe piece. I can lock my toe in normally, make it a little more difficult to release or make it impossible to come out. This is a great assurance when you're headed down a steeper slope, perhaps with really heavy snow and can't afford a release. On the subject of releasing, the reason I gave these 4 stars was for the brakes. I released a couple times when I first skied these before I realized they were adjusted improperly for the length of my boot. But the times I did release resulted in me chasing my ski 100yds down the hill. Powder is so much more fun on 2 skis rather than 1 moving "skateboard style." The brakes don't dig in enough to stop the ski on a slope greater than about 15 degrees. I feel this is something Dynafit needs to address with their brakes considering how many rockered skis are out there. Everything that makes a killer powder ski, keeps the brakes further from the ground. I found myself locking my toes in purely because I didn't want to risk a release skiing steep cheesecake pow. I never had brake issues with my barons but I would encourage anyone purchasing these bindings to inspect/modify the brakes before skiing anything technical. I will say that when I adjusted the bindings properly for my boot length my confidence increased.

Would a 100mm brake work on a 78mm waist ski? I'd like to be able to use without swapping the base plate/brake unit if possible.

I think you will run into some overhang issues with a 100 mm brake. I'd look for one closer to your actual ski width.

does anyone else have trouble getting out of these bindings? My buddies seem to push on the toe piece, but I have to pivot the heel piece, which requires some gymnastics for the first ski removed

Sierra R

Have you checked the spacing between the rear pins and your boot? Perhaps the bindings were not adjusted properly to your boot length. I push the toe piece down to release my forefoot and then twist my heel out of the pins. But if the length of the binding is not adjusted properly I could see you having trouble getting out.

After mounting these up on a 169cm Atomic Millennium ski, I'm wondering why I wasted so much time. I previously toured on Marker Barons, and being a small female, had a hard time hauling those cinder blocks up any sort of incline.

These bindings provide a HUGE advantage when skinning uphill. I beat 3 dudes up the skin track yesterday, (this is a first) who were hauling MFDs and Barons. I can't believe I waited so long to invest in Dynafits.

Downhill performance is awesome, I can jump off stuff and I've never had any release issues. They do require a higher degree of finesse to put on, but with time that process can be perfected.

The risers are also significantly easier to deploy than those on the barons. All around simple, elegant and lightweight design.

THESE ARE AMAZING.

These bindings are awesome. So light on the way up while still providing all the performance need for the downhill.

I recently purchased these and mounted them on a pair of 175 Atomic Centuries. I used to have a pair of clunky not so great touring bindings and am now realizing what I have been missing out on. These bindings are so lightweight and easy to use. The toe pivot is great and allows you to glide instead of lug your skis up the mountain.
I am an intermediate skier I am 5'7" 135lbs and I have these bindings set at a 7din and have not had any problems with them releasing. You do need to make sure that your toe holes have been 'cleaned' out of snow before clicking into ski mode. I have found if I engage my toe and wiggle it around before clicking in my heel in ski mode it helps to ensure the toe is not going to release from snow being packed in.

They should work fine. You only have 7mm (likely less) of overhang on each side.

Does anyone know what the difference between the Verticles and the Radicals is? Do the new Radical have a "3 position step" that is the same as the Verticle?

There are a few differences. Radicals toes are beefier metal, have a 75mm wide under binding plate for better driving of wide skis and have "towers" which make engaging the toepiece easier. The heel does have 3 climbing positions: flat to the ski and 2 elevator heights. The elevators are much easier to use/change than the Vertical series. A flick of the pole does it. Hope this helps.

This is my first set of Dynafit bindings, and I am happy so far. I picked these over the verticals because of the updated heel design. So far I like it. It is very easy to change climbing heights. The only worry I have is the force that is put on the heel hinge for the risers. Overall, the design seems solid and user friendly.

what's the difference between the heel design of this one and to that of Vertical ST. I purchased the ST and just like you this is my first set of Dynafit bindings and I was very happy.. I'm trying to decide if I should keep them or go with these.. Your feedback would be appreciated

The radicals have flip up heel risers instead of having to rotate the whole heel piece to change heights.

It is possible, but on this season's bindings (2012/2013), you need to swap the entire base plate(minus the heelpiece), not just the brake. The price is about $80/pair.

2011 Stokes + 2012 Radical ST = good idea?

So I've noticed that the newer models of the Stokes have a slightly different mounting plate than my pair. The new mounting plates lack the two front and center holes that the previous model had.

Now, my question is does this matter at all for mounting my new 2012 Radical ST bindings that do not have the front and center screw. Instead they just have the four screws arranged at the four points of a square.

Know what I mean?

Thanks for any thoughts...I have had great luck on here getting advice in the past.

Hi Ryan, Dynafit rep here. No problem mounting the 2012 ST on the Stokes. If you are using the rearward location, the four screws in the toe piece will line up with 4 inserts. If you are using the forward location, there are 2 dimples in the ski's topsheet that mark the location for the forward-most screws. You will need to drill these 2 holes. The heelpiece will use the inserts in either position.

That sounds like a great setup! Definitely go with the 100mm brakes, the 110mm would be to large and possibly make contact with the snow when you lay it on its edge.

Karl, It won't be too big. You are only 4.5mm wider on each side. Plus, the spot where the brake arms hit is likely a bit wider than the waist dimension.
