One of the benefits of having a modular binding like the Marker Alpinist is that you can swap and replace parts as you please, but it also allows them to be lighter and better adapt to the individual skier. Here are a few of the spare parts we are stocking. All parts are sold in pairs.

Alpinist Heel Platforms - The heel support pads used in flat-on-ski mode which must be removed or installed depending on if brakes are being used or not.

Alpinist U-Springs, Low – Softest U-Spring available for the Alpinist heel piece, reserved for more relaxed skiing by lighter or less aggressive skiers.

Alpinist U-Springs, Medium – The most common U-Spring that most Alpinist users will find themselves using. Comes stock on the Alpinist 9.

Alpinist U-Springs, High – The stiffest spring found on the Alpinist bindings, stocked on the Alpinist 12. Reserved for heavier skiers, very aggressive skiers, or those that’d just rather not come out of their bindings.

Question from Joel Andersson
 
Im thinking of exchanging my u-springs to softer ones. Do you have a how to instruction?

Answer from Brett S
 
Thanks for reaching out, Joel. We don't have a tutorial posted, however, it is quite easy to do. On the back of the binding under the u-spring, you'll find a small 1.5mm allen bolt. You need to (carefully) undue that bolt, and slide the u-spring out. We've found it helpful to use expanding pliers to spread the u-spring apart, making it easier to slide it out. Reverse this process to put the replacement u-spring in! Please let us know if you have any other questions.

Question from Brian
 
I had the same U Spring question as above. I bought the Alpinist 12, but probably should have got the 9 as I am 58 now and the DIN chart for alpine bindings says 7 for me as a Type III skier even though in the past I was at 8 or 9. I now set most of my touring bindings to 7 as well. At 190Lbs and Type III, which U Spring would you suggest I use?

Answer from Will McD
 
Hi Brian,
From what you've just told me, I would go with the Low U-Springs. They should have you releasing roughly around an 8, closer to your other touring setups.

Question from Austin
 
I bought the alpinist 12 and the u-spring is way too stiff. At a skier type 2 I am a Din setting 6 and at skier type 3 I am a Din setting 7. With my resort setup, I ski very aggresive (type 3) and prefer my Din at an 8, however in the backcountry I don't ski as hard and am looking for as much safety I can get without sacrificing premature releases. I do plan on skiing harder in the backcountry over time so I don't want to go too soft. Given my Din settings, would you recommend the soft or medium u-spring??

Answer from Teddy Young
 
Hey Austin, thanks for reaching out! Based on that info, we'd recommend the soft u-spring.

Question from Randy Oakley
 
What is the approximate release value of the "Alpinist U-Springs, Low"
Running http://www.dincalculator.com/ with my wife's numbers gives a DIN value of 5 -- will the soft springs be "soft enough"
10/10/2020
Answer from Cole P
 
Hey Randy, the "Apinist U-Spring, Low" will be closer to a release value of eight. Keep in mind that the U-springs will be what dictates the vertical release, the lateral release which is adjusteable can be set to a three.

Answer from RandyOakley
 
Thanks -- I guess I'll have to wait for Marker to come out with an "extra-low" spring for the Alpinist to work for my wife.

Hi,
When you buy brakeless Alpinist bindings, is the heel platform included ?
If not I need to unscrew the heel ?

Answer from Zak M
 
Hey Antoine, the brakeless Alpinist does include the heel platform. You should be all set!

Partial review for the med U-spring. Thankful for Skimo.co for making these available! Coming from an alpine skiing background, my tendency is to buy bindings with release values/DIN a bit higher than my calculated RV/DIN. So, even though the RV I set my bindings to is 8, I end up feeling like getting a binding that goes to 12, which means I ended up getting the Alpinist 12 instead of the 9. The 12 does seem to have a near-impossible spring to step into, and putting the medium spring on has helped, along with knowing the vertical release is closer to what it should be.

Putting in the new spring is a bit of a challenge until you know the tip- use two pliers to pry open the end of the U-spring further to clear the slot, then simply tap in.

What RV does the low spring measure in at? Looking for the appropriate match for a RV of 7.

Answer from TSB
 
Hey Kyle, the low spring should be in the right vicinity for you! Feel free to fill out our Binding Finder and we can dig into it further.

Question from Tim
 
My wife has a difficult time engaging the rear binding with her Scarpa F1. The din is set to 5. Would the softer u spring help?
1/4/2020
Answer from Jeff
 
Tim, Yes it can. The Alpinist only has lateral adjustment, so she adjusts to 5, but the vertical release is fixed. For the Alpinist 9 we tested the Vertical release much higher, too. Swapping to the soft spring will make it easier and safer for her.
1/14/2021
Answer from Kirk T
 
The shape of the Scarpa boot sole (right below the tech fitting on the heel) might also be the culprit. In wildsnow's review of the Alpinist they discuss this problem - go down the article to the section about "kiss gap".
https://www.wildsnow.com/24743/zero-boot-ramp-and-feather-weight-marker-alpinist-first-look/
If the bottom surface of your wife's boot heel is too flat in the area below the tech fitting (like the F1 seems to be), instead of being tapered/rockered, you might try tapering it with a grinder and/or knife. Just a thought.

Question from Kevin Woolley
 
Looking at a used ski with Alpinist 12 binding. My ideal RV in the forward plane is 7-9 (chart says 6 but I prefer a little higher RV forward). Which spring would you recommend?
11/11/2019
Answer from TSB
 
Hi Kevin, we'd recommend the medium U-spring, which comes in at a release value of 9, if you wanted that higher forward/vertical RV. You could use the low U-spring if you wanted to have a release value below that.

Question from Dominic U.
 
Hi there,

I haven't seen these bindings in person but I am wondering if the marker u-spring has the same measurements/shape as the dynafit u-spring?
2/7/2019
Answer from Jeff
 
Dominic, There are Many different Dynafit bindings and they are not all the same. We have some springs for the Low Tech, see here https://skimo.co/dynafit-binding-parts
