I have the Marker Motion iPT w/ Piston integrated binding on my Volkl AC30 skis. I've adjusted the DIN and forward pressure, (yes, I know how), then went skiing in Utah last week. I want to move the binding 1 or 2 cm forward on the rail, then readjust the DIN/forward pressure.
I see that the lock screw has a lock/unlock symbol, but when I unlocked it, the binding did not move forward. Is there an easy way to do this? Also, do the AC30's have a mark on the ski that lines up with the center mark on the boot?
