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.

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.

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.

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.

Question from Andres
 
Looks like the radiacal ST heels are sold without the bases. Is this correct? Id so will they fit on the base/spindle from the older vertical ST?

Hi Andres, unfortunately the Radical and Vertical spindles are not compatible.

Question from Alexis
 
I have a pair of first gen (2012) radical st bindings (I already updated both heel pieces, which broke). I would like to get some spare parts for an extended trip I will do soon. Just want to confirm that the radical st heel pieces above would work. Thanks!!

Answer from jbo
 
Hi Alexis, yes all Radical ST generations are compatible.

Question from brian
 
I have a pair of first gen radical ft with a broken roof plate. I am starting to understand that this is a very common failure and that there was an updated parts package or replacement heel to fix it. I can't find any mention of it on Dynafit web site. How can I resolve this issue with my bindings. Do the gen 1 FT heel pieces you guys sell have the update?
3/7/2017
Answer from Trace Leches
 
Hey Brian, yeah that is an issue with the older Radical heel pieces unfortunately. There are 3 iterations of that heel piece now, the original, an updated heel piece (reinforced so it's a bit stronger), and then the latest iteration that has addressed this issue even further. How old are your bindings?

Question from Bjornar
 
Hey,
Which heel piece will fit reasonably with the speed radical toe piece that weighs less than the original speed radical heel tower? I have been using a la sportiva rt heel piece but these have broken on me and I want a bomber (and reasonably light) heel piece to match with the speed radical toes. Thanks!
2/23/2017
Answer from jbo
 
Hi Bjornar, you could try something like a Plum Race 150 heel on a Kreuzspitze 14mm plate (same hole pattern as Speed Radical).
