Mounting Salomon binding on Fischer RC4 WC GS skis with race plate

post #1 of 5
Thread Starter 

Just bought a quasi new pair of Fischer RC4 WC GS skis from a fellow bear.  They were previously mounted for Look PX bindings with a 317 mm BSL.  

 

My own BSL is 306 mm.  I have two binding options and three solutions:

 

1-  Used Salomon 900S Carbon bindings (no longer indemnified, but in very good condition).  I have the mounting template, but the front screw holes for the heel piece would have to be drilled where the mounting screws for the rear half of the race plate are located.  Also, the existing screw holes for the toe piece would interfere with the new holes for the Salomon toe piece.  The solution appears to mount it about 8 mm back of the line.  How much will that affect the ski's feel and performance?

 

2.  Solution #2 is to mount a Look PX 12 Race binding.  It looks like I will have to use the old set of screw holes, and move the heel piece forward 12mm, or alternatively, drill new holes 11 mm forward of the existing holes.  Either way, the boot center would be 5.5 mm forward of the line.  

 

Of these two options, which one is the best or least problematic?  Would you rather have the binding mounted slightly forward or back of the line?

 

3.   I am also thinking of filling in the existing holes in the race plate with Epoxy Steel, and redrilling for the PX 12.  Would this hold the screws properly, if there is partial interference with the old screw holes (new hole center would be 5.5 mm from center of existing holes, hence partial overlap, since holes are 3.5 mm diameter.?

Don't bother mounting Salomons or filling holes. Solution #2 is the one. Just mount another set of PX12's and you'll be fine. Those are the 27M skis advertised here? If so, the boot being 5mm forward will make them come around easier. Most of my gs skis are mounted with Atomic race bindings which have adjustments 7mm apart, makes it easy to find the right spot which is very seldom on center. These are 183-191's, several different brands. Almost all of them work better 1 click forward, while some are set at 2 clicks. Just depends on the ski. For example.....Head 186/25.4 feel best all the way (2 clicks / 14mm) forward......but a pr. of 188/25 Fischers and same Atomic bindings, boots on center they're a bit ponderous into the turn and just feel long (to me).....14mm forward they initiate much quicker but the tails don't feel quite right.......set at 7mm forward everything feels right. With your Fischers I think 5.5mm forward would feel much better than on center, and you can do that without changing any of the mounting holes.

Another example. This season a couple of us got 2013 - 183 Fischers, >27mm radius, more like about 28M or so. Mine came with bindings mounted at what turned out the be 5mm forward. They're perfect. My friend self-mounted Atomic race bindings on his and got the toepiece too far back. After fooling with different settings, the best one for him turned out to be almost exactly the same as mine, 6mm forward.

They are indeed the ones that were listed here by Lukc.

Utah is right on point above.  Nothing to add to that.

Yes, the Fischer GS works best mounted forward as described by Utah.  Another option you can do iff there is interference with the holes is to swap the plates front to rear.  Both pieces are the the same and thiscna give you more options for bindings.  But still mount forward!  

 

Oh, and dont bother using the 900S carbon.  If it was the metal 900 equip you would be fine but not the carbon (plastic) one
