I have the Dynafit ST Rotation 10 bindings, and am looking to switch to a narrower set of brakes. Would the Radical ST brakes be compatible?
(As far as I can tell the heel units are identical, but Dynafit's naming is pretty confusing...)
Thank you in advance!

Thanks for reaching out, Tish. While the base plates look similar, they're in fact not compatible, sorry about that! The reason lies in the ST rotation is a zero gapped binding with forward pressure whereas the ST Radical isn't. Please let us know if you have any other questions!

Does this brake work for the superlite 150 binding?

Hi Ryan, there are a bunch of brakes in this listing. If you select Superlite, XXmm from the drop down, you will get XX width brakes for the Superlite 150.

I’ve got ST Radicals w/ 100mm brake and want to remount to a 118mm ski. Just want to double check — will the Radical ST 130mm be the best choice of what you have in stock? Here is the binding I’ve got: https://www.dynafit.com/en-us/st-radical-100mm-08-0000049115

Hi Galen,
Yes, the 130mm Radical ST brakes will be the best option for skis with a waist width of 118mm. Generally, brakes can be stretched up to 6mm to accommodate a wider ski. However, 18mm will be far too much for the 100mm Radical ST brakes.

Hi there ! Is the radical ST brake compatible with the Rotation 12 binding? Or are they different?

Hey Marcos, the ST brakes are not compatible with the Rotation bindings. If you look at the drop-down menu above you can see the Rotation brake option toward the bottom.

Hi, I have the Superlite bindings mounted to 95mm wide skis. Would the 90mm brakes work, or would I need to find the 105mm brakes somewhere else? Thanks

Hey John, thanks for reaching out! I think the 90mm brakes could work for you, maybe with just a tiny bit of bending.

I am looking to add brakes to this Dynafit Radical Speed binding and was wondering which ones are the right ones.
My skis are a bit less than 80 mm wide.

Vinz, the Speed Radical is the Brakeless version of the Radical ST binding. Dynafit does not make a brake that fits directly onto this binding plate.
You can get the Radical ST, 82mm brake, remove your heels and take the turret off and add to the Brake. The Brake has the same mounting pattern as your binding.

Thanks much Jeff! What about the Kreuzspitze Heel Brake 85 mm? Would that also be a suitable alternative? Which do you think is the better solution for my daughter who may do more resort than backcountry skiing but would like to be able to switch back and forth: https://skimo.co/kreuzspitze-heel-brakes

Vinz, I was going to mention that too. Really. That will work too.

Hi Irina,
The Radical ST brakes will not be compatible with the Dynafit Radical ST 2.0. The Radical 2.0 has been succeeded by the Dynafit ST Rotation. In both bindings, the brake is integrated into the baseplate, so you will need to replace the baseplate to get those narrower brakes.
Based on the new waist width of your ski, the ST Rotation 90mm brakes should work great!

I have some unused Dynafit beast 14s in 120 mm, what are my options to replace the brakes w/105mm?
3/16/2021
Thanks for your question, Scott. You'll need a new baseplate, which we don't carry for that particular binding. Since the binding has been out of circulation for quite a while, we would encourage you to reach out to Dynafit. Please let us know if you have any other questions!

Any chance the super lite 105s will fit 108 skis?
3/8/2021
Hey Dustin, the 105mm brakes should work well with those 108mm skis. You would just need to bend the brakes slightly to fit, but definitely doable.

Hi,
For a 120mm width ski with radical ST binding, would the 130mm radical ST brakes fit ok? And are the rotation ST brakes different from the radical ST brakes? Could you do the 120mm rotation ST brake with a radical binding?
Thanks!

Hi Annie,
The 130mm Radical ST Brakes will certainly work! They will overhang 5mm per side, which should not affect your skiing when retracted. However, the ST Rotation brakes will not be compatible with the Radical ST binding!

Hi,
I have skis that are a 105 waist and I'm thinking about buying a set of used Dynafit ST Radical 2.0 bindings that have 102mm brakes. Will those squeeze on there and work? If not, what brakes should I buy to fit this binding and my skis? Thanks!

Hi Emily, they can be hard to measure. The options for the Radical 2.0 were 90mm or 105mm. You definitely want the 105s.

The 135mms are already mounted onto my skis. I am wanting to know if the holes will line up or if the shop will have to make new holes?
1/12/2021
Hi Krystle, whoops! You'd think the installer would give you a heads up. But yes, the 90mm baseplate/brake assembly fits in the same holes as the 135. It does require unmounting the heels from the ski to do the swap.

Well I think the language barrier as I’m in Germany didn’t help! I’ll order the 90s now!! Thank you!!

Hello
I just purchased a 105mm underfoot ski and want to swap my 2016 Dynafit Radical FTs over from my other setup. The current brakes are 120mm, which I know is too wide. Since the FTs are discontinued, is there another brake that is compatible with that binding? Or do I need to replace the bindings completely?
Also, what's the ideal brake width for a 105mm ski?
Thanks!

Hi Joseph, for the original Radical FT (we call them 1.0), you would want the 110mm brakes. However, if your current brakes are 120mm, that makes me suspect you actually have a Radical FT 2.0, since that brake width exists with the 2.0 and not the 1.0. If that's the case, you would want the 105mm Rotation brakes.
If you want to be certain which model you need, please send us a photo of your binding! help@skimo.co

Thanks for the quick response! I'm not positive on the exact model since I can't find the old receipt, but I measured the brakes again and they are indeed 120mm.

12/21/2020
Hi Joseph, yep, that is the 2.0! You want the ST Rotation 105 brakes. The FT 2.0 is now called the ST Rotation 12 binding (with a few tweaks).
