No LeeL, they are last year's Garmont Megarides.( Da blue ones)
Why, have you heard of some issue regarding Scarpa TX and dynafits? Pray tell?

Please don't tell the teletips lynch mob as I dont want to feed the BS.  A friend of mine had the TX and had to file down the boot around the dynafit fittings as the plastic in the boot impeded closure of the toes so he would also always pop out.  Pretty alarming to see how often he pre-released until he took a file to a perfectly new pair of Scarpa boots.

I've had no issue with my MegaRides and Dynafits fwiw

This thread comes at good time as my new box of ST's are waiting to be mounted for spring touring. I hope to get used to them this spring and then give em a try in next year's powder.
Thanks

I hadn't heard the specifics, but a recent Scarpa interview at TTips had Kim Miller describing how they've adjusted the setting of the Dynafit toe fittings in next year's model, so it was obviously a problem for a number of folks.

Nice tools Larry, although one looks a bit like a prison shiv.  They let you have Dynafits in the clink?

Here's a pic of a couple of home made accesories I carry snapped to my belly pack that I've found quite convenient. Just a bit more refined I hope than the rusty nail carried in a pocket.   Smiley

Hmph... Well I won't apologize for not liking Dynafit bindings.  Not only are they finicky, but the fact that you have to bend over and carefully hold the ski while attaching the toe piece reminds me of my 3-pin days.  And I don't know how many times I was more than uncomfortable with that maneuver while on steep terrain or some precarious position in a chute.  So now I just shake my head while my buddies do the hairy scary to mount up while I just step in and go...seems like I'm always waiting for those too pound smart usability foolish Dynafit'ers!

Great closing argument, counselor!   Wink

It dawned on me that Dynafits have taken the place of the much loved and maligned Ramer binding. (R.I.P. Paul Ramer.) The Ramers were trailblazers, but they were finicky too. Perhaps we backcountry skiers have a repressed need for such gear.



As evidence, here's a picture of one of my first alpine touring bindings, a pair of Ramer Model R's bought in 1979. In a fit of nostalgia, I mounted them (appropriately) on two-by-fours for my attic museum. Beneath the binding are accessories that came with it, from left to right:

+ Grease for the ball-and-socket hinge
+ Bolt wrench
+ Heel piece shims (helpfully labeled "SHIM" - thanks Paul!)
+ Heel lift extender

Larry's excellent tools brought the old Ramers to mind and I couldn't resist hauling them out.

Prison shivs can be fashioned from virtually anything: TV antennas, bed springs, or my personal favorite, a sharpened toothbrush handle!  Don't even think about booting up a skin track near me (or Larry for that matter).

I carry this to clean out the snow that can get packed under the heel piece of my Freerides preventing them from locking into ski mode.

Lowell,  I also used Paul Ramers binding in the "old days" and remember greasing the sockets.  After the Ramer binding, I switched to the Dynafit TLT and have a couple pairs.  I have been fortunate that the bindings have performed well for mny yeaars.  My only minor problem is the icing under the front spring that Sky explained well.

You guys are making me nostalgic for my two generations of Rainey tele bindings - the original Super Loop with the big-ass rubber bungie around the heel which needed for the toeplate to be tuned with a chainsaw file so the toeplate wouldn't slice the cable (among other fiddling required), and the third generation SL with the delrin throw piece with the funky gear and pawl for adjusting cable length which had a tendency to fail utterly in year one. Generation one was alluring in its simplicity and worked pretty well with lace-up leather boots, but...

No wonder I've been so happy with my Dynafits!

Ah, my hat's off to you, Scotty.

Anyone that can take a poor understanding of basis mechanical simplicity and turn it into a major "federal case" with over 800 posts deserves special recognition. Smiley
 
Please forgive me for noticing, but your banishment from work and and machinery may be having a deleterious effect on your mechanical skills. Wink  Others seem to be doing much better with simple machinery.  It's evident that Sky, Tim and others have quickly picked up on the more subtle quirks of this engineering marvel and adjusted accordingly, to their benefit.

I, myself, also not being as quick on the uptake, only switched to Dynafits many years ago at the suggestion of the techs at Marmot Mtn, after breaking and/or prematurely wearing out several pairs of Fristchi's.

Since then the only trouble I've had with the several pairs of Dynafits centered around my lack of patience or understand of the design, an affliction which may have somehow migrated to you Wink

Now I'm not particularly bright, just lazy.  But that attribute has helped me figure out how to put my skis on without bending over and how to avoid carrying extra gear to keep my bindings on my feet.  A small dollop of white lithium grease in the boot toe cups once in a while seems to make it easy for the pins to "drill out" any persistent ice and a spritz of slippery stuff here and there before leaving home and an occasional cycling of the toe piece cross bars seems to do the trick for me.

It will be sad to see you go back to work because you then may not have the time to craft and coax these lengthy threads out of almost nothing to work with... a pure work of art to be sure.

Good to know more of the story behind this thread - thanks Ron!  Wink

Yeah, I've never had to bend to put the skis on - that one surprised me. Not even to pull up the toe lever when in tour mode - my BD pole grips have a little lip that seems to have been designed to assist with this manouver.

You bring up a good point re:Fritschis. While skiing with a few guides from Canada, who get to see a lot of different gear go through a lot of torture testing, I asked which bindings were most reliable. They said "3 pin and Dynafit," and then rattled off a list of failure cases for all the other bindings folks in our group had, including the Fritschis (something about having the heel lifter in the wrong position for whatever you were trying to do with the binding at that moment whihc struck me as not that hard to accidentally replicate..."

You guys are making me nostalgic ...

After thinking about it, I remembered that the wrench shown in my Ramer photo above didn't come with the original Model R binding. (The pictured tool came with a later version of the binding, called the Ramer Classic.)

The tool that came with the Model R was more interesting. Here's a sketch of it:



This tool was both a bolt wrench and a clamp. The clamp was used to lock out the lateral release function of the binding. You slipped the clamp over the parallel bars with the hex-shaped notches nestled over the place where the toe bail was installed. Its function was the same as the toe-piece lock of the Dynafit binding. Some people found it necessary to lock the binding while touring. I never had much trouble with this, so I carried the clamp/wrench as maintenance tool only.

Do any old Ramer users out there still have a pair of these clamp/wrenches? I'd pay good money to add them to my collection. After I quit using my original Ramers in 1987, I gave them to my brother Gordy (with the clamp/wrenches too). He used them for a few years and passed them on to another friend. I got the bindings back a few years ago, but I don't seem to have the clamp/wrench tools anymore.

====

Edited to add:

In the 1970s and 80s, most AT bindings were designed to work with just about any boot, including leather mountaineering boots. Paul Ramer provided two different toe bails with his bindings, one that was angular (for use with DIN-style ski boots) and one that was rounded (for use with mountaineering boots). At about the same time, plastic mountaineering boots (e.g. Koflach "Ultra" and Kastinger "Reinhold Messner") appeared on the market. Remarkably, some of the first plastic climbing boots were not designed for step-in crampons, because their were almost no step-in crampons on the market. (Maybe none.) So, the first plastic climbing boots had almost no notch in the toe that you could clamp a binding on. For this reason, I made my own toe bails for my Ramer bindings, which fit my plastic mountaineering boots perfectly. I used some steel rod stock from the neighborhood hardware store. Those toe bails never broke. You can see one of them in the Ramer photo above.

Talk about fiddly!!

I hated that gear thing. Don forget the lifters with extra long screws that would gradually tear the core of your skis to shreds and rip out miles from nowhere. Or the cable guides that would spontaneously blow off the side of the binding. Thankfully he redeemed himself with the Hammerhead, although the HH has its quirks to be sure.

Q for the Dynafit abusers among us. Has anyone ever broken the toe-pincers? They seem pretty stout. That guy in Canada hung upside down from them in a crevasse (he was locked in tour mode) so theres one data point. I ask because it would seem trivial to build a block that inhibits forward pivoting of the boot to effectively create a "tele mode" for boots like the F3 and TX.That would be putting quite a lot of stress on those pincers, but it sounds like they might be able to handle it. I would love to have a tele mode for rolling tours or that perfect field of corn that just begs for a tele turn.

Thanks for the acknowledgement Ron but it's not that hard. Just combine the follwing nouns SUBARU, DYNAFIT, CRYSTAL SKI AREA with the follwing adjectives SUCK, FRUSTRATING, DANGEROUS etc. and all hell breaks loose.
Alas I will be going back to work soon and all this fun will come to an end.

As to the Canadian guides comments regarding the dynafit and 3 pin being the most reliable . I guess I defer to their superior knowledge but I find that surprising. Never, ever had a problem with Fritschi's. Could it be that the Fritschi users that the guides are basing their opinion upon are hucking and skiing harder because they are not on Dynafits and therefore causing more breakages?
Are large hucks possible on Dynafits?

So, yeah, entirely possible.  Pretty slick.  Not going to be a production binding, from all that I can see, but it's an interesting idea.

THE BIG QUESTION: ARE DYNAFITS HUCKABLE?

I watched a guy huck one of the cliffs on the Headwall in Tuckerman Ravine a few years ago.  It was probably a 40 footer onto medium hard corn.  He landed somewhat ugly, but his skis stayed on and he skied away to lively cheers from the lunch rocks audience, whose full attention he'd captured.  When he skied by, I was checking out his set up -- K2 AK Launchers mounted with TLT comforts.   I wondered if he'd put them in tour mode before launching, but couldn't tell.  Pretty impressive...

One thing I haven't seen mentioned in this thread so far that might be relevant:

If the sole of the boot wears down under the toe (too much scree walking etc) then it will not press down on the plastic "trigger" in the middle of the pincers and will fail to accomplish the desired clamping action. I believe Wildsnow has something about this, including a fix with, what else, duct tape!

Ahh yes, here it is: http://www.wildsnow.com/articles/dynafit_faq/dynafit_faq1.html#wingclose

Snowboy, I checked your suggestion and that's the problem with mine. There are so worn down at toe that they are not always fully engaging toe plate and pincers.
Thanks for the suggestion and fix!

I've always wanted a pair of bindings that relied upon duct tape to work. Huh
