Question from Pico
 
Parts query: I just broke off the plastic "shelf" on a Dynafit Vertical heel piece. Dynafit says they have no spare parts available. Would you happen to have a Vertical heel piece for parts in your bone yard?

Answer from Trace Leches
 
Hey Pico! Looks like we're out at the moment and probably for the foreseeable future. The good news is that we have a Used Dynafit Parts page that's worth keeping an eye on. Worst case, the Vertical heel hole pattern matches up with the Speed Radical and Speed Turn heel pieces so a full blown replacement wouldn't be the end of the world.

Question from Adrian B
 
I have a broken Radical ST heel as in the picture. I would like to buy a replacement, but as far as I heard damages on this model are quite frequent. What other heel piece is compatible with this one? Thank you!

Answer from Nate
 
Hi Adrian, for the number of Radical ST bindings that have been sold over time, they actually have a decent track record of performance. The design and most of the bindings out there are getting on in age and are probably ready for retirement so it's not a shock when a heel breaks from time to time but the parts are still pretty available and worth replacing.

As for compatibility, there really isn't anything that's cross compatible as a drop in replacement/upgrade. Only the Radical ST heel pieces will be compatible with the base plate that you have pictured.

Hi Nate,

Thank you for your answer.
Which Radical ST? 1 or 2.0?

Question from jake lyman
 
Hey, I have some old old Radical FT bindings, with the black plastic volcanos, and my heel piece broke. I would love to fix them, or jerry rig something by getting another headpiece which would be compatible. Any help? Screw pattern is the standard dynafit pattern, or something like that. Thanks!!
2/4/2018
Answer from jbo
 
Hi Jake, if you mean Vertical FTs (the ones with volcanoes), you can get replacement roofs (speed or comfort plates) from B&D. Note you'll also need the volcanoes if you go with comfort plates. Other than that, you're looking at new heel pieces.

Answer from jacob l
 
Thanks JBO!! I think I'll just get a new heelpiece, the speed turn 2.0's, and make a mutant binding. Thanks!!

Question from Mark Mueller
 
Good morning,
I've broken my Dynafit Radical ST heel piece (about 2 years old). I'd like to order a new one, but don't know which to choose; Radical ST or Radical ST 2.0? Thanks for the help.
I've broke several of these heels over the last couple of years where the top portion with the pins attaches to the lower part of the binding. Do you know, is this problem common or rare? Thanks.
1/19/2018
Answer from Nate
 
Hi Mark, it sounds likely that you have a Radical ST binding. If it is all black and gray, you have a Radical ST, if there is some green and bronze color to it, you have a Radical ST 2.0. We currently have both in stock, and you can select the one you need from the drop down menu above.

I'm sorry to hear that you've broken several of these. It seems that if there is going to be a failure of the Radical ST binding, that the heel piece is the weakest link. That being said, we have many customers who have never had a problem so it seems to be hit or miss as to whether or not its an issue.

Question from Toby W
 
Hello from Kyrgyzstan. I am here for the winter and have q question for you. I have a pair of Fischer Hannibal 94 with Dynafit TLT Radical 2.0 bindings. The ski is light but the bindings are not as I am now skiing on the set up I bought from you this summer. I am skiing with a pair of Fischer Carbon Ski Mo boots I bought from you. I want to ski the Hannibals at times with these boots and am considering putting a pair of Superlight 2.0 heels on the skis (with Quiver Killers). What do you think? How do you think they would do with the TLT Radical 2.0 toe pieces as I dont really want to replace those too. I think the pattern of the two heel pieces is the same.
So there you have it. Thanks, Toby Wheeler

Answer from Trace Leches
 
Hey Toby! Ha, it's tough to go back to heavy gear once you get a taste of the good stuff isn't it?

Officially the Radical 2.0 toe is only compatible with the Radical 2.0 heel because of the forward pressure/rotating plate. The Rad 2.0 toe has seriously soft toe springs (intentionally) to help with the lateral release factors, so it could potentially give you some really low release values. Short answer: I wouldn't do it. If you're looking at lightening up then I'd say just sell the old binding and start from square one with a complete Superlite 2.0.

Question from Joe
 
I am looking to swap heel pieces from speed turns to speed radicals, is the stack height/pin height the same and toe piece compatibility the same that it will be an easy swap? Thanks.

Answer from jbo
 
Hi Joe, yes they are pretty much interchangeable. Same pin heights and mounting patterns.

Question from John
 
Hey guys
What kind of epoxy do you recommend for the binding screws?
11/18/2017
Answer from jbo
 
Hi John, the sealant recommendations typically come from the manufacturer of the skis, not the bindings. It depends on the construction of the ski what works best.

Answer from Spindogg
 
Ah ok
Well while I have you - do you happen to know what kind of epoxy is recommended for Atomic Backland Descenders?
11/18/2017
Answer from jbo
 
A waterproof wood glue is fine with those. You can step up to epoxy if the holes are janky.

Any kind of epoxy? Is there a brand that's better than others?

Question from John Spinney
 
Hey guys
I just cracked part of the tower (white plastic near base) on a speed radical heel (older generation before the rotation fix). I have a set of speed turn heels - is it possible to do surgery and replace the white plastic part of the speed radical with the white plastic part of the speed turn? The white part looks exactly the same as far as I can tell.
11/13/2017
Answer from Trace Leches
 
Hey John! Dang, that's a bummer! I'm gonna say yes, it's probably possible, but unless you already have a speed turn heel that you were going to throw away it's probably not worth it. I'd just grab a completely new Speed Rad heel piece.
11/13/2017
Answer from jbo
 
Hi John, you probably also want to pull out the pins that cause that cracking and install the anti-twist kit.

Answer from Spindogg
 
thanks guys - i actually just ordered a set of new radical heels from you instead of trying to tinker with this.

Question from Ryan
 
Two questions:

1) Is it possible to use the Speed Radical heel with the TLT Radical ST 2.0 toe? Or is this a case of "yer gonna die"? Since I already have the toes, and they're mounted with Quiver Killers, I'm wondering if I can save a few bucks this way. If this isn't the best idea, is it possible, using Quiver Killers, to switch between the TLT Radical 2.0 toe and the Speed Radical toe? Or will it be too close?
2) Is it possible, using Quiver Killers, to switch between the TLT Radical 2.0 heel and the Speed Radical heel on the same ski? Or will it be too close?

Considering this setup on my Nanga Parbats to save a little weight for longer tours.

Thanks in advance.

Answer from Trace Leches
 
Hey Ryan, thanks for reaching out!

1) This isn't definitely a case of "yer gonna die" but it's also not definitely not a case of "yer gonna die." Maybe more of a case of "we don't recommend it, but try at yer own risk if yer motivated." Either way, probably not wise to mix any part of the Rad 2.0 and any part of a more traditional binding like the Speed Rad as the springs in both the toe and heel on each binding is tuned differently and who knows how they will end up behaving in release tests. Could be so low that the binding is barely usable or it could be so high that the binding release forces exceed that of the strength of your bone structure. Either scenario isn't anywhere near ideal though and I don't recommend it.

2) I checked the hole pattern for both bindings and it looks like that's probably not gonna work. We recommend at least 15mm between each QK insert and there's just not enough space in the Radical 2.0 hole pattern for a Speed Radical to fit with inserts. You could potentially get away with it if you didn't have inserts in the ski, but there's still not a whole lot of potential there.

Answer from CALVIN E
 
FWIW, I'm doing the inverse of that with very good results - Using Speed Radical toes with Radical ST 2.0 heels. Releases are appropriate (it does release, but no pre-releases). Skied many times with this setup on Voile Vectors last year, both BC and on Resort. I used the B&D 6.4mm shims under the toes.
9/8/2018
Answer from Trace Leches
 
That's awesome to hear actually, I'm glad to hear that it's going well. We have definitely built a few of these setups before and have had no negative reactions (so far) so it sounds like it's entirely doable. Sounds like my apprehension was a bit excessive to begin with. Still not recommended by Dynafit and we haven't been able to put these setups on our release testing machine so I can't comment on exactly how it performs under stress, but it sounds like it's working close enough to appropriately that it's feasible, which is sweet.
