Question from Jeremy Allyn
 
What is width of the freeride spacer? Is the ski width recommendation of >95mm
fairly conservative? Thinking of these for Dynastar M Tour 99s
11/18/2022
Answer from Tristan M
 
Hi Jeremy,

Looks like the ATK Freeride Spacers measure at about 67mm wide. You will be completely fine on the Dynastar M-Tour 99.

Question from Zesheng H
 
Hi: skimo

my questions are:
1. is it necessary to add freeride spacer, or it's the case for aggressive skier?
2. when the binding installed with brakes, in which boots having contact with break levers, can fill the gap between boots and ski sheets. Can I say it provides similar function of freeride spacer, at lease in some bindings (like atomic backland bindings with brakes)?
3. do you need brake installed to add the freeride spacer for (ATK raider binding), or can be installed without brake? my guess only need brake seat cover or brake pad (see image) to properly fasten the spacer?

Thank you
Zesheng
11/15/2022
Answer from Jeff
 
Hello Zesheng,
1. The Freeride spacer is definitely an option. Bigger skier and wider skis would benefit from them.
2. With most brake bindings, the heel of the boot doesn't have a lot of contact with the AFD plate. The Freeride spacers are further outboard and have more boot contact.
3. You can use the Freeride spacers without the brakes. The Brake seat cover isn't entirely necessary, But that depression seems to be perfect for snow to pack in and buildup there.

Question from Ben
 
Why wouldn't the Raider toe shim work with the C-Raider? They have a narrower set of front holes to accommodate their slightly different mount pattern vs. the regular Raider
10/25/2022
Answer from Jeff
 
Ben, You are right, the mounting holes do match. The shape and the raised ridges do not match up. You could trim the ridge at the toe. Only possible issue is the tip of the C Raider toe piece will not be supported. And that is where the Ski/walk lever is. Which could reduce the leverage to lock out the Toe in walk mode.
10/25/2022
Answer from Ben
 
Thanks Jeff! Why did they make the narrower set of front holes if its not designed to be used with the c-raider toe? It feels like you need a phd to understand ATK's product line
10/25/2022
Answer from Jeff
 
Ben, the Raiders had two different mounting patterns and we will not get into that story.

Answer from Eric N
 
Is there a different toe shim that you recommend using with the C-Raider? Maybe the classic shims? I'm looking to reduce the delta a bit on my C-Raiders.

Question from Gabe
 
Are these compatible with the helio 145 bindings? Looking to swap for a 6 value.
10/25/2022
Answer from Jeff
 
Hi Gabe, If you are talking about the TI and Rolling springs, they aren't designed for the Trofeo/Helio 145 binding. And wouldn't change them to a 6 release heel. The 6, 8 and 10 release is in the actual heel piece, not just the U spring.

Question from Ian
 
What are the release values for the "standard" and "lightweight" springs?
10/8/2022
Answer from jbo
 
Hi Ian, ATK targets 9 and 6 respectively, but it may vary a bit based on your boot sole length.
10/8/2022
Answer from Ian M
 
Thanks! Will either work with the Kuluar 9? Or just the standard springs?
10/8/2022
Answer from jbo
 
Hi Ian, no, the Kuluar uses longer steel springs like the Trofeo. We're hoping to get those in stock at some point.

Question from Ryan G
 
Hello,

I have a pair of ATK race bindings I got from a friend used. They used them a lot and so have I. I have been skiing them on a pair of Scarpa Alien 3.0. At the end of last season I started noticing I had more vertical play in the heal connection between the boot/binding. I tried repositioning the heal piece many times on the adjustment plate but the play remained. Is it possible that I have worn down the U-spring to the point that I am getting this play and that new U-springs could be the fix? I never knew what they looked like new, but they are definitely grooves worn into my U-springs, making me think that perhaps they are just worn down.

Thanks for the advice. I am optimistic that I can just buy a set of U-springs from you guys and keep rolling with these bindings.
9/20/2022
Answer from Cole P
 
Ryan, if your U-springs have deep groves that can explain the vertical play. You will want to get the Titanium U Spring under the drop-down menu. I would also check your boots heel tech inserts which can get worn as well. Also double-check that your heel gap is set at 4mm when you install the new U-springs to be at manufacturer spec.

Question from Josh
 
I would like to setup my ATK C-Raiders with Freeride Spacers and without brakes. Do I also need the Brake Seat Cover to prevent snow buildup, or will the Freeride Spacer serve this purpose by itself?
9/15/2022
Answer from Cole P
 
Hey Josh, the ATK freeride spacer does not include the brake seat cover. If you are concerned about ice build-up we recommend buying the brake seat cover as well.

Question from Michael K
 
What is the advantage of the brake seat cover vs. the freeride spacer, if the latter also allows the boot to rest on the ski instead of the pins and transmit power more directly? Does the cover protect better whatever is exposed after removing the brake?
Also, can you explain how exactly the power transfer via the freeride spacer improves the preceived quality of power transmission, or the quality of the ride? The boot bottom is usually stiff, so I have a hard time imagining how it makes a difference whether power is transferred via the pins or via the sole.
Also, is the freeride spacer compatible with the brakes installed simultaneously?
Also, would the freeride spacer increase the longevity of the boot and/or the pins in the long run, as the weight rests on the spacer rather than on the pins?
Thanks for your help!
8/5/2022
Answer from Ian C
 
Hi Michael, the brake seat cover is a single piece of static plastic used to fill the aperture once brakes have been removed from an ATK heel. Its purpose is to ensure snow buildup does not occur underneath your heel pins. By contrast, the freeride spacer consists of two anti-friction plates mounted on either side of your brake pad (or where your brake pad would be if you already removed the brakes). By increasing the friction-free surface area against which your boot outsole comes into contact, these spacers provide a grounded feel vs. the more static sensation caused by levitating a few mm off your ski topsheet.

To answer your other questions directly:
- It is completely plausible that freeride spacers improve the longevity of the pins or boot inserts in the long run, but I have no evidence to support this. The primary advantage is ski feel.
- The spacer and brakes can be installed simultaneously. This is the most frequent setup you will see on full-featured ATK bindings where brakes come by default.

Question from Fisher
 
I have a pair of BD Helio 350 bindings - now discontinued as Black Diamond carrys them with the original ATK Raider branding

These Helio 350s certainly seem to have the exact same heel as the Raiders, will the Raider Freeride spacers work with them?

Would love to be able to test using them back and forth without drilling!
3/15/2022
Answer from Tristan M
 
Hi Fischer,

You are correct, the Black Diamond Helio 350 is compatible with the ATK Raider Freeride Spacer. It looks like we are currently out of stock. If you would like to be set up for a notification that will alert you when we get more, reach out to help@skimo.co!

Question from Trevor
 
Hello, can you advise the correct U spring and extra / replacement mounting screws for the ATK free raider 14? Would it be the rolling in U spring and 13mm screws from the Hagan parts page? Thanks!
2/1/2022
Answer from Will McD
 
Hey Trevor, the Freeraider doesn't have a removable/replaceable heel spring. For the toe you will indeed want 4 of the 13mm screws on the Hagan Parts page and for the heel you will want 4 "15.5 Pan-headed torx screws" from the Dynafit Binding Screws page.

I am using both the raider toe shims and brake seat covers on the raider 12. I love to fiddle with my gear to get exactly what I want and its awesome that ATK provides all of these parts to help me do so.

I have used b&d shims in the past but the ATK ones are milled exactly for this toe, giving a much cleaner look.

The brake seat covers work well for filling the hole created by yanking the brakes out, not much else to say there.

keep fiddling.

Question from Duncan
 
Is the brake cover compatible with the Raider freeride spacer, or would it necessitate getting the universal spacer instead?
1/21/2022
Answer from Ian C
 
Hey Duncan, the wings on the brake seat cover would interfere with the Raider freeride spacer. However, you could actually remove the brake, skip the brake seat cover and keep the Raider spacer, which will meet your boot heel to protect the heel piece even without the cover. Hope that helps!

Hey R C, we just measured a 97mm Kuluar brake at 38g heavier than the brake seat cover!

Question from Tom
 
Are the rolling U springs compatible with any of the other non-ATK bindings? Also, what release values are available in the rollers? I'm assuming they will just drop right into a pair of Helio 180's
10/28/2021
Answer from jbo
 
Hi Tom, those are also compatible with the BD Helio 110 and the Hagan Ultra and ZR bindings. There is only one spring strength, typically around an 8. Sadly they don't fit in the 180s which have a longer steel spring.

Hi,
Will the brake seat cover work with my ATK Crest 10 and Hagan Pure 10?
Is it $19.95 for one piece or for a pair?
Thanks!

Answer from Zak M
 
Hey Celia, thanks for the question. The brake seat cover does work for both the ATK Crest 10 and Hagan Pure 10, and yes the price we have listed is for a single brake cover so you would need to purchase two. Let us know if you have any more questions!
