Slight hijack of this thread.

Does anyone have a good source for the Head/Tyrolia PRD 12 bindings? Just purchased a pair of minimally used iM 78's with Mojo 12's. Can't use the original binding placement of the Mojo's and the skis will need to be redrilled. Would rather put on PDR 12's instead of the Mojos. Would rather spend less than $190 ( :'() that Ski Depot wants for a pair of PDR 12's

Jim...being the equip savvy fella I am..I had to google what a PDR12 is... :-X  But found a couple of listings you might check out....not sure if these are the width you would need....if so, the price point might be a bit better....hope this helps....b

Gary paid about the same for his PRD12's -- $189 at Al's Ski Barn -- after a lot of shopping around.  Sorry, I don't know of another source with a better price.   But....I wanted to toss another option out there for you to think about.  How about reusing the Mojos but putting them on a Tyrolia plate? This gives you adjustability and a bit of extra stand height, for far less money than new bindings.  The plates sell for about $30 to $50 in the shops up here.  I checked the Tyrolia tech manual, and the Mojos are compatible with all their plates.

The only thing I'm not clear on is how such a plate will affect ski performance.  Could be a good thing, if you choose the right plate that allows the ski to flex freely.  I just started a new thread today, asking that very question, and have had a couple of responses, but no real authoritative in-depth discussion as yet.  Stay tuned....

Jim:
Make sure you are getting the binding s AND Power Rail plate. The ad that Byron posted, for example, sounds like it could be just the bindings.

Brakes too wide on those? 88mm an OK fit for a 78mm ski? Something else to consider before ordering.....

Good point Svend. But in this case, probably ok. 10 mm wider is only 5 mm wider on each side. However, 78 brakes on a 88 ski would be a real problem.

BTW, the brakes can be ordered from Tyrolia and are interchangeable with no tools required.

Just giving a Head's Up to Jim2 -- if he needs to buy new brakes, then it's not such a great deal in the end.  But you're right, 5mm extra per side isn't too bad....

Guys I understand the point about leverage in 3D snow conditions...IMO and based on how I ski...My Marker Schizzo's give me 25mm of stack height for my 112 Wailers and my Kastle FX84's....I don't need or want anymore than that. I don't ski pow at speeds that require high edge angle...for me in boot high and more is about soft edges. AND it doesn't take much more than that to get a fat board to turn in powder....step on it two footed and there's plenty of platform to shorten turns and create great carve, drift or scarve type turns. Additionally, there's added weight with any platform system...why add it.

Just not seeing the need for anymore stack height that the 25mm I've already got for my pow skis and my FX84's.

Not thinking there's any right or wrong way just what brings the skier the best indivdual feel for their needs.

Thanks everyone for your replies to my query.  :)

Svend, which Tyrolia plate are you referring to?

Jim 1, I too wondered if the evo site included the plate. I agree that buying the plate and different brake arms could nickle and dime me close to the $190  (:'() of buying at Al's or Ski depot.

These "new" used skis are getting more pricy. $250 for the skis, $190 for bindings, shop costs to mount the new bindings and plug the old holes. Should I consider an older railflex which can be picked up for ~$100?

Jim2 -- Tyrolia makes several plates, but the most common is the Speedplate 13.  All Mojo bindings are compatible with all Tyrolia plates. 

http://www.tyrolia.com/ski-bindings/ski-binding-line-201112/plates/index.html

Which one you choose depends on your needs and the stand height that you want.  But the SP13 is probably the best for a ski like the iM78.  The rubber pad below, and the center hinge should give you good vibration absorption and allow the ski to flex.  BTW, the predecessor to this plate was called the Carve Plate 13 (CP13), and I just saw this one in a local shop for $15, new.  It is very light, so should not add much more weight to the ski than, say, a Railflex or Powerail plate.  The pre-drilled holes match all adult Tyrolia/Head bindings, and allow you to move the binding fore-aft simply by remounting them in the holes.  I have done this several times with a couple of Head Supershape skis.  Works great.

If you PM me your email address, I can forward you a couple of current and older Tyrolia tech manuals for you to look at the specs, stand height of bindings, plate compatibility, etc.

Let me know if you need more insight....

The CP13 is a nice plate. However, without a Free Flex mounted on it I suspect the ski will have a dead spot under the binding when the boot is snapped in place.

Hi Max.....  Why would that be? If the plate allows the ski to flex underfoot, because of the central hinge point, how would that create a dead spot? Shouldn't be any different from a flat mount or lifter fixed mount....theoretica lly....  Or would the boot-plate combo somehow prevent the ski from flexing?

On that topic, I've never quite understood why the Freeflex bindings have the joining mechanism between toe and heel -- the older ones have pre-loaded springs, later ones have a metal strip or narrow plate joined with a bolt in the middle.  The springs I sort of get -- they serve to un-flex the ski back to flat for better snow contact.  But the newer metal strip....no idea what that does, mechanically speaking.

If you could illuminate this, it would be great.

Thanks!

Meput:  I think the PowerRail is better (wider, a bit lower, and much easier to adjust), but I don't think it is twice as good. So for half the price, I would go with the Railflex, depending on what you see coming down the road.

What moved Lynn and I in a PowerRail direction was our choice of other skis.  The PowerRail has been standard on a number of Head and Fischer skis for a couple of years.  We knew Lynn was looking for a Fischer Progressor 8, so we put the PowerRail on her Ski Logik and got the bindings effectively free when she bought her Progressor 8's.

Sooo, if you thought that your SuperShape replacement might come with a PowerRail from the factory, then you might a big chunk of that money back by not having to buy bindings for the other new skis.

Max:  I'm pretty sure that all of the flex associated with the Free-Flex is in the plate (and, as you mentioned, does include a screw in the middle to stiffen the ski if wanted).  The front half of the plate is fixed, all of the float is in the back half of the plate. Of course, the mounting holes in the plate itself only match up with the FreeFlex bindings.


The key feature of all of these bindings is some sort of bar that connects the toe and the heel, so as to maintain a fixed distance between the two. With the free-flex that bar is in the bindings.  With the RailFlex, the bar is the rail, with the Power Rail the bar is also in the plate (no rail directly connecting the two bindings).

I'm not sure about that one, Jim.  As far as I know, the Freeflex hole pattern is the same as most other adult Head/Tyrolia bindings.  According to the Tyrolia tech manual, you can use a number of different bindings on those plates, using the same holes in the plate -- Freeflex, Mojo, LD, and SL.  Of course, the system bindings won't work, nor will rental ones, but the ones mentioned are listed as compatible with all their plates.

Jim,

ForeRunner Shop had some '10/'11 leftover KERS SS's which will be my older SS replacement. Just in time, as the edge metal is starting to show through the base on my older SS's  >:(. The new SS's came with FreeFlex's on them. So much for the power rail idea, but thank you.
