Hydraulic vs spring binding systems ; Marker Piston

post #1 of 6

Question for you binding mavens: Are there any potential differences between how a piston and a coil spring will handle compressive loads while skiing? I've been on both, but it's hard to sort out the binding's performance from the ski's.

If you are referring to Marker's piston and comparing it to something like the newer Fischer system, they do the opposite thing. The piston actually dampens the ski, while the springs in the fischer plate increase the rebound of the ski (I think). I can't speak a lot about the Fischer plates, but the Piston compresses very easily and then slowly comes back out as I recall when playing with one once... so your ski rebounds less violently.

Yep, talking about Marker Piston vs. Tyrolia. Wondering under what circumstances a "shock" binding would give a ski more life rather than less. That was my hunch; springs store energy and release it, the piston just absorbs it, presumably dissipates it as heat. But Tyrolias are attached to skis that are known for being damp and low-rebound, like some Elans, so I couldn't see if my assumption was off, or if the ski just determines rebound far more than the binding.

Marker Piston plate: what does it do?

My understanding is that the Piston plate uses a hydraulic damper to control the bending and rebound of a ski, limiting vibration and making the ride more smooth. I have heard other people say that energy is stored up in the damper when the ski is flexed, and it's release adds to the rebound of the ski. What's the real story?

At the risk of being a fountain of misinformation I say absorbs and dampens.

Marker actually uses two different piston systems. The "Comshock" piston is in the toe and is a fluid that stiffens when agitated. It is designed to dampen shock vibrations and provide more holding power in the toe for brief shock loads and vibration (technically described as non-newtonian fluids)

The Piston Control that attaches to the ski and binding interface, known as iPT, PCOS and Piston Control Turbo are designed to dampen ski ossilation

Skiers initiate quicker, cleaner and smoother turns. The feeling is simply sensational.
(and I'm merging these two similar threads).
