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.

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. All of our stock is current with this mechanism.

  • 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 25mm) 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.

Speed Radical vs Radical ST

The ST version of the Radicals weighs 183 grams (6.5oz) more than the Speed due to the inclusion of brakes and lift plates to accommodate them. To ease the pain of the missing brakes, Dynafit included optional leashes with the Speed Radicals to keep you on good terms with ski patrol. A few people might notice a difference in power transfer without the lift plates, but it's very few.

Speed Radical vs Speed Superlite

The Speed Superlite bindings cut 161 grams (5.7oz) and a host of options off the Radicals. The Superlites have no fore/aft heel adjustment so you have to mount for one pair of boots. They are also missing a flat riser option, Power Towers, and the optional leash. If these bullet points and $150 don't matter to you, the Superlites will get you to where your going faster.

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.

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.

Question from Kevin
 
On a recent multiday tour, both toe piece plastic levers broke. Is there a fix with a more robust part?
2/11/2017
Answer from jbo
 
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.

Question from sarah
 
Hello,
I have the fischer transalp 88 skis and transalp ts lite boots and am looking for a binding for tours and some back country skiing. I am not a racer, so weight is not a huge issue, although light is good.... with that said, would the dynafit speed radical be a good fit? Was also looking at superlight white, but it seems that it's only a half pound of weight shedded and costs $150 more, any other significant differences
12/16/2016
Answer from jbo
 
Hi Sarah, the Speed Rad would be a decent option for that setup; it's fully featured and reliable. The Superlite would save you some grams at the cost of a fixed vertical release and no BSL adjustment (can't adjust for different boots).

Question from RMC
 
Is skier weight a consideration with these at all, other than DIN setting? Should heavier skiers move towards the ST/FT? I like the leash concept and weight savings but am concerned with durability, drive-ability, etc.
11/22/2016
Answer from jbo
 
Hi RMC, there is no published skier weight limit, and the latest iteration seems to be holding up well. The ST/FT 1.0s are the same construction so not any stronger, though the ST/FT 2.0s are noticeably beefed up. You could also check out the G3 ION LT 12 which is a bit beefier yet still light sans brakes.

I paired these with the Movement Sweet Apple skis for my girlfriend. Over two seasons, she has toured on them regularly and used them at the resort maybe 10 times with no issues at all. (She weighs 105 lbs and is not an aggressive skier.) They are not the absolute lightest, but the combination of weight, function and price is hard to beat. Another reason I chose these for her, and not a race binding, is that she needs a very low release setting, and these go down to 4. She skis them on a 4 or 5, and they have released when needed, without pre-releasing. Small people take note.
The adjustable heel is also handy for boot changes without remounting, as happened when her F1 Evos were recalled.

I have been on Dynafit bindings since I began skiing a couple years ago. The first set was the Radical ST, so I felt good about changing to the Speed Radical when I got some new skis because I preferred using a leash to brakes when in the backcountry, and the fact that the Radical lets you skin with your boot flat to the ski as well.

A year on, I have been reasonably happy with the Speed Radical bindings. There is nothing that stands out to me as a drawback to them other than the weight (I recently purchased the Superlight 2.0 and that binding has changed my mind about binding weight...).

It seems that the rotation pin has been a problem in the past (I have the 15-16 model), but I haven't had any issues with them. Also, I've had no problems with the 'rotation issue' so far, but have spent more time area skiing this winter because my son has been learning to ski as well.

All in all, it the Speed Radical has been a solid binding for me. I'm certainly interested in the Plum Guide and the G3 Ion, but until I get some new skis, there doesn't seem to be any reason to mess with something that works - which the SR does...

Question from Scott
 
What's the difference between the Speed Turn 2.0 and the Speed Radical?
2/24/2016
Answer from jbo
 
Hi Scott, the Radical risers are little flippers, whereas the Turn heel rotates to change risers. The Radical toes have Power Towers that help with boot entry as well.

Question from Bill
 
Is this the latest version of the Speed Radicals and NOT the first iteration with the plastic housing?

Answer from jbo
 
Hi Bill, yes, all of our stock is current from the 2014/15 season. They come with the new anti-twist device.

Question from Elizabeth
 
Can I buy the Radical ST w/ Baseplate brakes to use with these?

Answer from Tim D
 
Unfortunately not Elizabeth, the tower is of incompatible height with the ST baseplates.

60+ days on these bindings used with La Sportiva Spitfires.

I like these bindings but have had the same "rotation issue" as most everyone else. I'm getting ready to purchase/add the Maruelli fix to them to help (and cut weight to boot). I am a larger guy with relatively flexible boots who likes to use the heel risers. I find that the 1st riser position causes the rotation most often (far too often, especially on side hill skinning) but it is very rare to have a rotation in the 2nd/top riser position ... so i often skip the 1st.

http://skimo.co/maruelli-binding-parts

With all that being said: I've had no other mechanical issues with them, love the light weight, like not having a ski break, have used them with the Dynafit Ski Crampon (works great), have had them release when needed but never when unwanted. Personally, i like having the 3 heel positions and use all 3 regularly.

Side note: ski leashes. I use the Dynafit leash and attach it to my boot with medium strength zip-ties. The rational is it would likely break if caught in an avalanche but not a normal wreck or accidental release. No problems with this system so far.
