Dynafit Speed Radical Binding

The Dynafit Speed Radical is the standard by which touring bindings are measured. Evolved from the tried and true TLT Speed, the binding is designed to be safer, easier to use, and support a wider range of boots sizes and release values. The skiability and precision control of the previous incarnation remain intact. If you are looking for a lightweight binding that gives you more adjustability and riser options than a race binding, the Speed Radical may be for you.

  • Power Towers on the toe pieces are easier to step into and offer protection from pre-release during a side impact.
  • Speed Step climbing bars enable you to change riser heights with a flick of a finger or pole, no heel rotation necessary.
  • Adjustable heel piece (up to 22mm) lets you step in with various size boots or loan them out to a friend with big feet.
  • Release values adjust between 4 and 10 for both lateral and vertical releases, so you can customize your injury prevention.
  • Made with forged 7075 aluminum, high-strength plastic, chromoly and stainless steel to ensure your skis stay attached.
  • Comes with optional leashes so you can make your rig resort legal when accessing the side-country.

Update 2015/16: All Speed Radicals now come with an anti-rotation mechanism that is mounted under the heel to prevent accidentally spinning into ski mode while skinning.

Update 2017/18: An additional refinforcement plate was installed under the heel roof, adding around 15 grams. All of our stock is current with this update.

Update 2018/19: The most popular touring binding dropped a noticeable amount of weight and got a face lift just in time for ski season. The updated aluminum toe piece is 31g lighter and the binding gets updated anodizing and looks really spiffy!

Update 2019/20: What a neat paint job, it's the same great binding just now in Skimo Co blue!

Update 2021/22: Redesigned toe lever and all aluminum construction on the toe, aluminum plate to replace the plastic on the heel with some cool branding as well.

I've use these bindings for years on my go-to mountaineering / lightweight setup and absolutely abused them. Still going strong! I have nothing at all negative to say. Great for transitions in super technical terrain. Light for long approaches. Never had a problem in any downhill situation and I've been in them all. Good and easy to use riser options for uphill. I had them before the anti-rotation mechanism was introduced years back and once that was added, the only problem I ever had was fixed. I plan to be using and fully trusting these for years to come

Question from Andrew
 
I have a pair of 2017 Dynafit ST rotations on a 178 Zero G 95. This is my spring touring ski for steep skiing. The binding is heavier than I would prefer, can I safely remount it with a Dynafit Speed Radical?
2/26/2021
Answer from Julieana
 
Hey Andrew, those hole patterns are pretty different, so you should be able to remount just fine.

The blend of price and function is very high with this binding. I decided to go break-less after seeing my fair share of skis skittering into oblivion on cascade volcanos. Remember most breaks are useless during transitions when they are locked in touring mode. I’ve got two pair in play right now, but I keep reading about lighter and better performing bindings with less delta. A true workhorse, but it’s days for me might be numbered.

Seriously a great built binding that stands the test of time. I have close to 100 days on these and no signs of slowing down any time soon. Great entry level pin binding for anyone. They are light(-er than frames), easy to work with, ski well and are feature-rich.

The reason I give 4 stars is due to the weight and heel/toe delta. There are a lot of bindings which are quite a bit lighter that do the job just as well.

I found the heel/toe delta (if you don't know what this is, search the Skimo.co site for "binding pin heights") to be quite excessive and hard to ski at +16. After two seasons of struggling I had SkimoCo put the B&D shims on and it was a night and day difference. This lessens the riser effect but does wonders for skiing capabilities.

Question from Jarrett
 
I've heard the leashes can release in case you are caught in an avalanche and the leashes are attached to a plastic piece on the binding which can break off. is the plastic piece replaceable if this does happen and you get your ski back?
1/7/2021
Answer from Patrick C
 
Jarrett,

Great question! The leash is attached to a metal cord loop, which is routed around a metal pin which is embedded in the plastic of the toe lever. If this were to break you could purchase a Toe Lever as a replacement. Hope this helps!

Question from Jeff Schmalenberg
 
Do you have to mount with anti-rotation plate or can you pitch it? I can't remember what I did for my last mount, but the plate isn't there, so I must have thrown them away. Is there an issue doing that?

Been skiing for years in them without issue. Thoughts?
10/21/2020
Answer from jbo
 
Hi Jeff, with models that ship with the plate, you definitely want to mount it, otherwise there will be a lot of slop in the heel. The first generation of this binding used an internal pin to prevent rotation which did not need the plate...at least until the pin sheared.

There's a popular saying about weight, price, and performance: you can only pick two. You can expect to pay out the nose for the lightest and sexiest of bindings and the definition of the word "performance" begins to change when you start prioritizing the uphill to the down.

As has been said before by several other reviewers, these bindings do a pretty darn good job at being lightweight(-ish), inexpensive(-ish), and perform admirably in a wide variety of settings. From the backcountry, to side-country, to slack-country: these bindings will not only keep you attached to your skis, but release when needed. The sky-high stiletto risers work well to compensate for AT boots with minimal ankle flexion. The 22mm of BSL adjustment comes in handy if you find yourself loaning out your gear. The crazy high ramp angle didn't bother me until recently when I discovered a whole anodized aluminum world of 0-5mm deltas... then it bothered me a lot. I never tried shims, but they seem like a pretty decent solution if you're married to this binding. Will these be your forever bindings? Probably not. Are they a great place to start? Absolutely!

If you have a little extra money kicking around and aren't terribly concerned with vertical release or specific DIN values, check out the Plum Oazo for a binding that weighs a whole lot less and has nearly the same functionality.

Hi,

I'm interested in the Dynafit Speed radical but not sure whether i can also install brakes. It's possible?

Thank!

Answer from Cole P
 
Hello Victor, the Speed Radicals are compatible with Kreuzspitze Heel Brakes. Dynafit makes the Radical ST binding which is similar to the Speed Radical but with brakes.

Mmmm the Speed Radicals! Love these bindings. For me, they are the perfect balance of lightweight and durability. They release predictably and are nearly indestructible. I have the ST Rotations on another set of skis and cannot tell the difference in ride between the two. The main differences I have noticed are in weight, elasticity, and the rotations included ski brake. I have my speed radicals mounted on my lighter touring/ski mountaineering setup and appreciate the simplicity of the overall design. I have never had these release inadvertently and am confident in taking them in conditions where a lost ski might have consequences. Just do it!

Bottom line: For this skier, these bindings offer the best balance between usability, weight, cost, and safety for a dedicated backcountry touring setup.

In addition to the Speed Radicals, I've ridden the Speed Turns and Radical ST 2.0 and 1.0s. I've sold all of those other bindings and now have these on my three touring setups.

Stepping in and locking the toe are easier without the rotating toe offered on on more expensive Dynafit Radical bindings.

Going brakeless saves weight and improves speed/usability during transitions.

Compared to the Speed Turn, the risers on the speed radical are much easier to deploy and stow.

IMPORTANT NOTE: Go check out skimo.co binding ramp delta table. These bindings offer one of the highest ramp deltas posted. This will mean you will have an increased forward lean compared to many other bindings available on this site. If you prefer a more aggressive forward stance while skiing, consider the B&D shims for the toe piece.

Question from Jared Nelson
 
Hey guys thanks for all the info! I'm seriously considering these bindings, but am a little hesitant based on safety. Would appreciate hearing from someone who uses them regularly, how real are any concerns about pre release or other safety release issues? Thanks!
2/14/2019
Answer from eric
 
Jared- In our testing the speed radical has a very consistent release value. If elastic travel and safety are paramount then I would suggest looking at the Rotation series from Dynafit. They have TUV certification the speed radical does not.
2/14/2019
Answer from Jared N
 
Eric, Thanks for the info, i'm currently on a set of Radical 2.0s, so that is my baseline. I have had zero issues with the Rad 2.0, but since the Speed Rad is quite a bit different wanted to get a feel for any issues (some stated below). I'm not hucking meat off cliffs, just want good knees at 60. Sounds like as long as you are not doing big air, these are solid for release/retention. Is that a fair statement?
2/15/2019
Answer from jbo
 
Hi Jared, that is a fair assessment. The release is a bit more reliable with the Radical 2 due to the rotating toe piece and lack of a heel gap, but the Speed Rad is sufficient for most folks casually skiing the backcountry.

I've had 2 pairs of these (on Cho Oyus and Voile Vector BCs) with every iteration of the warranty replacement heels. The heels never stopped autorotating on steep side hills; that is not only inconvenient, but dangerous. Packed snow and ice builds up under the boot heel worse than any other binding I've had (Vertical ST, Radical ST, Superlite 2.O, Plum Guide & Yaks, and Kingpins). It was so bad I finall covered the bsl adjustment screw & track and plate screws with permanent silicone adhesive; that did help a lot; using Maxiglide, Armorall, silicone spray, waterprood grease, silicone paste, etc. did little. I disliked the flipping climbing aids--they always seemed to flip inconviently on their own. For a minimalist binding these are heavier than most of the competition. But they did work and worked fine when the snow wasn't deep or in a sintering mood.

Reply from jbo
 
Hi Andrew, thanks for the feedback. For what it's worth, in our experience the rotation issues were licked with the version that introduced the little nubbin that gets mounted under/off to the side of the heel. It would be hard to rotate accidentally over that!

The old classics, decently light for starting out and reliable workhorses. The unbreakable Dynafit toe piece, paired with adjustable release values, and multiple heel risers, can't go wrong with these.

Pushed these hard enough that the toe pins rounded off to such a degree I was worried about release from my toe while skiing, never actually released so perhaps not a problem.

As these things wear the heels begin to turn under the weight of your boot while skinning, slipping from walk into ski mode. This can be quite aggravating especially on steep icy sections, fixed by replacing the plastic bearing inside the heel tower, or my recommendation, mounting your skis with Maruelli anti-twist plates: https://skimo.co/maruelli-binding-parts. (Work wonders and lighten the binding up).

Question from Angus
 
Do the Speed Radicals have the same mounting pattern as the Vertical FT’s as I’m wanting to swap to a lighter binding with a lower DIN?
12/17/2017
Answer from Trace Leches
 
Hey Angus, thanks for reaching out! In the toe, no. In the heel, yes! We have a whole article dedicated to the hole patterns here! The heel should be able to pop into the old holes just fine, whereas the toe will be able to re-use two of the existing holes (you can choose front or back) and then you'll have to drill two other holes.

Is there a compatible brake that I can add on? I have had two leashes break on me now.

Answer from jbo
 
Hi Adam, there is no brake designed to work with the Speed Radical. You could add a universal brake such as the Kreuzspitze, but it needs to be removed for skinning.

I bought a pair of these to throw on a pair of Atomic Tacoras for summer and early winter skiing. I also have a pair on my Voile V6s. So far I've had the chance to use 'em on perfect corn, slush, avalanche debris, and even some pencil/knife hard couloir snow, and they have kept me securely attached to my skis. No prereleases yet, they drive my old non-rockered skis well, and I think they are a great balance of weight, durability, and features. I also like the added heel anti-rotation stopper. Unless you are doing some regular resort skiing and need brakes, or dropping cliff bands and need some serious retention, look no further.

Question from Kelly
 
Do any of the current Dynafit bindings use the 5 hole mount? My 15 year old dynafit bindings are no longer passing safety checks, but I like my skis, wondering if I can just get new bindings that would fit in the same holes or whether I'm stuck looking for new skis too.
2/18/2017
Answer from jbo
 
Hi Kelly, no current Dynafit bindings have that pattern, but some other brands do, e.g. Plum. You can also plug a couple holes and drill a couple new ones for the latest Dynafits.

Hi Kevin, the stock toe levers are all that's available. They are easily replaceable and that is something Dynafit warranties if there was no abuse.
