So I'm trying to make a pretty significant fore-aft adjustment on my wife's 149cm Volkl 724 Gamma skis that have the Marker Motion M10 bindings (the skis are circa 2004-2005). From the pictures, you can see that the center of the running surface (CRS, Sharpie mark) is substantially ahead of the center point of the ski (the mark just to the left of the "149"), by about 3.5 inches. The problem is that my wife has very small feet (women's 5.5, 265 BSL) and from the center of her foot to the ball of her foot is only about 2.25". So that puts her BOF about 1.25" (~3cm) behind the CRS. The last time she was on the skis, she said that she felt too far back, so I'm trying to do something about it.
The boot size selectors insert from the bottom into the toe and heel pieces and lock together with a tab, and then this system slides onto the rail and is locked in place by a pin that goes through both boot selectors and notches in the rail that are built into the ski. The rail has 4 sets of notches, all but one of which is useless because it you were to try to use them, either the toe or heel pieces would not be fully on the rail. The best that I can do is get her about 1cm farther forward by setting the rear boot selector in the 260 position and the front in the 280 position, then taking up the gap with the forward pressure adjuster. With the front boot selector in the 290 position, the forward pressure adjuster doesn't have enough travel to allow the screw to be flush with the boot engaged.
Is there something I'm missing here, or this a limitation of this particular binding system. If so, I'm pretty disappointed that 1 cm of adjustment is all that can reasonably be obtained. Thanks.
