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.
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.
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?
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.
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?
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.
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?
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 Please contact us at email@example.com to help assist you.
