4 BAR TECH
A STEP FORWARD IN SKIING ERGONOMICS
Go to your stairs. Try walking up them with just your toes. Now try walking up them with the balls of your feet forward.
This is the difference between Daymakers Alpine Adapters and all other alpine touring bindings on the market. Our Patent-Pending design utilizes a 4-bar linkage to create a larger, more stable platform aligned under the balls of your feet when walking up hills.
Walking on the balls of your feet is a much more powerful and stable stance than a rigid board extending from your toes.
IT'S LIKE 4WD FOR YOUR SKINS
Our 4Bar-Tech works much like a 2WD vs 4WD vehicle in the snow. A specific amount of weight must be moved, but how you disperse the drive of this vehicle's weight over 2 tires or 4 tires (increased area of friction) will reduce the amount of force in which each wheel must generate off the snow to propel your vehicle forwards.
Due to Daymakers' rear link, the force of your body's weight is distributed over an area about the size of your foot. In traditional single pivot point bindings, the force you apply is located only directly underneath that pivot point (a very small area). If you follow the formula that P (pressure) = Force/Area, and the force is consistent in both models (you weigh the same), then the amount of pressure put on the snow and the threads of your skins is smallest in the Daymakers' configuration.
Have you ever taken a step uphill on skins and had your traction blow out as you rotated your weight over that foot? That is because the grip of the snow to the layer below, or the threading of your skins cannot handle the force which you are applying to it. If you broaden the surface area to which you are distributing your weight over, you will decrease the amount of force per square inch thus minimizing those nasty blowouts!!
The 4bar tech creates this huge stable platform. When walking up steeps, you typically have to rely on taking a step, then pivoting on your hinge as quick as you can until making contact between your boot and the elevator which gives you pressure into the snow over an area about the size of your boot, thus giving you proper traction once your foot makes this contact. But until it makes contact with your elevator, you're screwed from a friction and stability standpoint.
Traditional touring systems hang the weight of the ski off the front of the toe. Our linkage shifts the weight of the ski rearward as it is lifted off the snow. This reduces fatigue on the quadriceps, so you can go further.
The movements from the boot are transferred through the two widely spaced links into the ski, and the result is an incredibly stiff interface that pivots smoothly and will hold pressure to the ski's edge on the steepest slopes with the fattest skis.
