Boot center on volkl race skis

post #1 of 17
Thread Starter 
I have three pair of volkl skis, a pair of 165 Racetiger SL WC, a pair of 190 Racetiger GS WC, and a pair of 180 P60 GS WC. On each pair I have the marker piston plate.

Looking across all three, I am not sure the piston plates were mounted in the right places. But I cant see where the boot center mark is because the race plates are there.

On the sidewall of each ski, it has printed the ski length and the letter "I". Does the letter "I" indicate boot center? If not, is there any other way, short of pulling off the piston plates, to tell where boot center should be?

Thanks

The I is probably the centermark but I have an other option for you. Mount your bindings according to the Ball Of Foot consept.

Press both ski bases together and mark with a pencil where they contact both in the front and in the back. This is the running surface.

Measure the disstance, divide it by two and put a mark on your skis. This is the center of the running surface.

Take your boot and put it on your foot. Tap on the inside of the boot untill you find the spot that you consider your ball of foot pressure point and mark it on your boot. This is the BOF mark of the boot.

Align both boot BOF mark and ski running surface center point. This is where your boot should be placed.

I started doing this last year and found out that I had to mount the boot up to 40mm forward of the original boot center mark (Head iRace). If your boot centermark aligns with the I marked on the sidewall of the ski then you know for a fact that its the centermark but Im pritty sure that you will find your boot 10-20mm forward of this position.

Good luck

I've always assumed the I is the centerline. I don't know what else it could be other than the ski reminding you of its autonomy.

The Marker piston plate is mounted based on boot toe. For Volkl race skis the boot center mark is ignored and the boot toe position is found by measuring from the tail of the ski. The Volkl race room produces a chart that provides the measurement for the various models and lengths.

tdk6 what happens when the ski is forward waisted (or more likely a twin) or has a proprietary side cut technology?

Yes, good question. I think that this kind of measurement works only if the ski is a regular sidecut ski. Twintip skis by the way have the bindings very far forwards so I guess this kind of measurement would put the binding too far back. Does sertainly not work for twin tip skis. But if you have regular SL or GS skis like the skis in question I think that it is an option worth considering. There is no harm in making the measurements and look where the centermark ends up. My Blizzards and my Heads have the same kind of sidecut but the Blizzards have the centermark much further forwards.

I concur. This is the way all the volkls were mounted for our team last season, and this method was confirmed by the western race rep and the factory.

Is there somewhere I can get a copy of that chart? I think at least one of my plates may be in the wrong place.

Also, once the plate is mounted, how do you decide which holes to mount the bindings into?

Thanks

If you can tell me what year each of the skis are I can look at my sheets and tell you the measurement. I also have the chart that shows which holes to use but I would need to scan it and probably wont have a chance to for the next few days.

That would be super. Here are my skis:

Racetiger '06 SL 165 cm (with the older marker plates)
Racetiger GS 190 cm
P60 GC 180 cm

Ok I was told exactly the same thing you are saying with regards to the toe mounting.

However I kept researching this and I read the Marker training/shop manual for 07/08 and they state that the procedure for mounting the piston plate is to first determine which toe position you will be using on the piston plate then place the boot on the plate and line up the center mark.
This leads me to believe that they are still looking to have the boot on center.
I was also told that the toe positions in the manual for position “a” and “c” are reversed

So I have a pair of undrilled '07 Racetiger SLs. What's the consensus on the matter? Do I mount with the "I" as the boot center?

I had my Racetiger SL Race stocks mounted and after corecting the toe mount for the correct holes (the installation instructions have "a" and "c" switched) the boot center mark is dead center over the I on the ski. Now this may be a coincidence. I sugest taking them to a reputable shop that speciliazes in Race skis's.

but how to find the spot that i consider the ball of foot presure point . do you have any details ?

 

thanks!

I have the stupidest question, when you say boot toe is this the actual toe box, the end of the area where your toes are? or is it the tip of the boot, the flat part that is used for the bindings?

 

I purchased racetigers and as stated above I have a tail to boot toe measurment for the binding placement

Interesting thread. I see I have replied earlier but back then I had no experiance with volkl skis. Now I have. I have a bunch of different racing skis for testing. Generally speaking they have their boot center mark very far forward compared to for example Atomic skis.

Here is a brochure that specifies mounting points for 2011/2012 racetigers
