Whether it's replacement parts or additional accessories, here are all the bits and pieces we have collected for your ATK bindings.

Titanium U-Springs - Pair of titanium heel forks for the SL World Cup and Revolution bindings. Also works with the Hagan Ultra, ZR, and BD Helio 110 bindings. Available in standard stiffness and "lightweight" for lighter folks.

Rolling In U-Springs - The most advanced forks on the market. Made of titanium with rollers on the end to reduce wear, ease step-in, and smooth the forward release function. Choose from standard or lightweight stiffness / skier size.

Trofeo Spring - These are the replacement springs for the Trofeo binding. Comes as a pair and includes screws required for installation. Black Diamond was even nice enough to include instructions in the bag.

Race Flaps - These are the race flaps that let you change uphill/downhill modes on ATK race bindings (SL and Revolution). Also works with Hagan Ultra, ZR, and BD Helio 110 bindings. Sold in pairs in multiple colors.

Crampon Slots - Aluminum - For those of us who'd like an option to add some ATK or Black Diamond compatible crampons to our setup, here's a removable receptor. 8 grams per side, plus screws.

Crampon Slots - Carbon - If you need extra bite, these receptors can be added to the C-Raider or Candy bindings. Seven grams each.

Classic Toe Shims - This is the toe shim designed for Kuluar, RT Evo, Haute Route, Trofeo, and older Crest bindings. It is 4mm thick and comes with screws. These ship with the DPS R10 & H10 and are compatible with the Hagan Pure & Pin Up bindings.

Raider Toe Shims - For our freeride category skiers who like a flatter setup, this binding-specific toe shim reduces drop by 4mm on ATK Raider bindings. Includes longer screws necessary to mount. Note: Does not work with C-Raider, Raider SL, or EVO toes.

Raider Evo Toe Shims - Designed to work with the Raider Evo series of bindings. These are 4mm thick and come with longer screws necessary for mounting.

Speed Shims - These are shims that reduce heel-toe drop by 4mm. These are designed to work with bindings that use the "Speed" toepiece. This includes Raider SL, Haute Route Plus (>24/25), Crest (>24/25), etc... These include longer screws needed for mounting.

Classic Freeride Spacers - This is the freeride spacer designed to work with V-Crest, Kuluar, RT (non-Evo), and older Crest bindings (pre-2024). Please note this goes under the entire base assembly and will increase the heel pin-height by 2mm. These ship with screws and require skis at least 95mm wide. This is the same spacer that ships with the DPS R10 bindings.

Raider Freeride Spacers - The stomp pads that fit the Raider 10/12, C-Raider, Freeraider 14/16, DPS R14, Hagan Boost and Core Pro bindings. Towers sit on either side of the Anti-Friction plates on the brake. Not recommended for skis narrower than 95mm underfoot. These weigh 28g each and will *not* work with ATK Evo, SL, or AP bindings.

Evo Freeride Spacers - Stomp pad for ATK Evo, AP, & SL bindings including the Raider 11/13, Freeraider 15, RT Evo, and newer Crests (2024+). Not recommended for skis narrower than 85mm. This is the same spacer found on the DPS H10 binding and is compatible with the Hagan Pin Up Evo and ATK Raider SL series. 37g each.

Universal Freeride Spacers - Works with any binding where the gap between the boot sole and the topsheet of the ski is between 14.5mm and 20mm. Spacer attaches directly to the ski. Adds 24g per ski and 2g in screws.

Classic Brake Seat Covers - Optional cover for any ATK binding with the push-button style rear brake (for when you want to take the brake off). NOT compatible with EVO or AP brake systems (Raider Evo, RT Evo, Raider SL). Sold in pairs. Only adds a svelte 4g per binding.

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.
1/13/2023
Answer from Abc
 
Is it confirmed that the rolling-in springs aren't compatible with the Trofeo? It appears ATK now makes a version with the rolling system (the brake version) and this makes it seem plausible that there is cross compatibility (though I know very little about the Trofeo, just seems like this might be a good upgrade)

What are the release values for the "standard" and "lightweight" springs?

Answer from jbo
 
Hi Ian, ATK targets 9 and 6 respectively, but it may vary a bit based on your boot sole length.

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 Heiko 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!

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!

Question from R C
 
What's the weight difference between the brake seat cover and a Crest/Raider/Kuluar brake? I'm assuming all the brake widths are pretty similar, but say a 80~90ish for reference

Answer from Ian C
 
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?

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!
