Monoski bindings

post #1 of 15
Thread Starter 

I am replacing the old Salomon 747 equipe demo bindings on my mono and am trying to find a suitable replacement. I mainly just ski on it when I'm cruising with my family on green and blue groomers.  None of the shops I have been to will touch it since they can't use their template.  Some of my requirements are:

1)  adjustable toe and heel.  Does this mean I need a demo binding, or something like Head/Tyrolia Free flex (good price at levelNine but wide brake)?  Boot center position on my ski is not marked, but I can calculate based on old mounting position.

2)  not crazy expensive - less than $200

3)  brake width - the ski has an equivalent width at the heel of about 63 mm.  Most brakes are considerably wider...

4)  hole pattern - I have been looking for the hole patterns for various bindings but am not having much luck.  Whichever I choose, I want to be sure I don't interfere with the holes I need to plug.

 

Suggestions and advice appreciated.

I have a question with regards to (1) in respect of (4).

I take it that a self-jigging binding would be welcome?    In which case - how often are you adjusting the boot size?   

With regard to (3) - since most bindings are not indemnified for this use anyway, why can't you just cut  the outside brake arm off and use a powder cord to meet ski area rules? 

 

FWIW, I assume you've already found this.

Based on the ski width 63mm I'm guessing this is for some kind of sitski and not what we'd call an old school mono ski.

 

I wasn't aware of a 747 demo had a moving toe piece.  I did have some 747 demo bindings on my 812s originally that got replaced with 877s when that heel blew.  Only the heel for my 747 demos had a long track.  Toe was standard.  The hole patterns were definitely different for 800 series.

I reckon this is exactly for an old school monoski - because of stance width.  

Most monoskis are what, 175mm to 200mm wide?   Let's say he's got a really old school Rossi

http://www.mono-ski.org/equipment/monoski/

 

so he's got a 195mm waist.     195-63 = 132mm to accomodate stance. 132/25.4 is only 5.2 inches.    

That's not much, but it's doable if the boots are also set up for an old school narrow stance.

It is an old school monoski.  Overall width is about 188.  Only reason I mention the narrow width is to figure out the brake width.  Inboard brake gets cut off, but I don't want the remaining arm to be hanging way out in space.  So I need to select brakes that are appropriate for skis that would be about 75 mm or less.  Levelnine sells brake arms for 78 mm width but that is additional $45.

I did find that, but I was not sure if the template applied to bindings like the rail flex or not. 

 

I guess I could cut off both brake arms and just use the powder cord, that would save the extra $45 for the narrow brakes.

 

I don't know what a self-jigging binding is.  I don't adjust boot sizes much, other than to let people try it out - perhaps my children.  I wanted the fore/aft adjustment because the ski is not marked for boot center and I don't know if it was mounted right in the first place.  I was the first customer to ski on it back in 1987 and bought it as a demo the following year.  There are 2 extra holes that the filled in when originally mounted and several scribe lines from where they set up to mount.  

 

And, yes the toe has adjustment.  I can get a photo if anyone wants to see it.

A self-jigging binding is one where the drill holes into the ski are exactly the same for all boot sizes.

 

None of the bindings in that template list fall into that category - unless you put them on a predrilled plate, which is what I was getting at.

 

You mount the predrilled plate to the ski, then simply pick the set of screw holes appropriate to the boot you want to ski that week/month/season, and if you need to change it you back the screws out and switch holes.


Alternatively you can use a rail-type binding.    No plate necessary, all the drill holes into the ski are exactly the same  for all boot sizes with these.

Tyrolia Railflex is an old rail type binding - no longer supported.   It would work for what you want but you'd be buying used. 

Tyrolia Powerrail is a newer rail type binding.   It would work for what you want.

Tyrolia Freeflex is *not* a rail type binding - there is a strap connecting toe and heel but the drill holes into the ski depend on boot sole length.

Sounds like the Powerrail is what I'm looking for.  The PRX12 appears to be my best bet.  Brake width is 80 mm.  If it is too wide, I'll just cut all 4 arms off as I use a leash anyways.  I appreciate the explaination and advice.

Cool.     Alternatively there might be something you could use over in the Atomic collection - I haven't kept up with the X bindings.

The Atomic X 12 VAR has a 70 mm brake.  Does it have to be mounted on a plate, or can I mount it directly to the ski?  It is a little more expensive but may be a better alternative.

no, it can be flat mounted

I bid on and won a pair of used X 12 VAR.  Thanks for all of the help!

It took a little reverse-engineering to figure out the heel-to-toe spacing, but they are mounted and look great!  I could not find any templates for these on the internet, so I did a practice install on an old pair of skis then made a pattern in AutoCAD to get everything perfectly aligned (much better than the original holes which were not very symmetrical).  The adjustment lever is pretty cool, gives me 2 cm forward and 1 cm rearward instantly!

 

I can't wait to get on the snow again!
