Dynafit on Bent Chetlers?

post #1 of 11
Thread Starter 

What's the current thinking on this.  Currently have:

 

Scott Crusair with Dynafits:

Bent Chetler with Marker Dukes:

 

1000

 

so can I change the dynafits over to my BC's?  I have heard a few horror stories about them not being suitable for big skis but has this been fixed with the new radicals.  Also given I have ST's would i be better off upgrading to new FT's?

 

thanks in advance.

I don't see why you couldn't.  What horror stories have you heard about Verticals on big skis?  I know a few people that run them on things like BD Megawatts with no issues.  

 

ST v. FT: the only significant difference is that the DIN on FTs goes to 12 (V. to 10 on the ST).  That and the (questionably effective) carbon "stiffener."

I have only heard it referred to in passing such as here:

 

Because the Radical FT is stated as compatible with skis over 100mm under foot, a lot of people mistakenly believe that this means it’s a stronger binding suitable for freeriding.  This is definitely not the case – they are still only a lightweight touring binding – ie if you use them for lots of off piste resort skiing then you risk one of the following: the pinholes in your boots wear out, the pins on the bindings wear out, the rear of the binding snaps off, the binding rips off the ski (yes, it still happens with the Radical FT), or you break your leg  – we’ve seen all of these, including a couple to ourselves – so you’ve been warned!

I have skied with these guys and trust their opinion, but then again I have seen quite a few people with Dynafits mounted on a variety of fat skis.

 

Do dynafit also make some kind of base plate for fatter ski mounting?

Well, I wouldn't recommend Dynafits for mainly resort riding - is that what you're planning to use them for?  You can use them at resorts - I do every so often - but if you want a resort binding, get a resort binding.  Dynafits are designed as a touring binding so they're more complex and make certain compromises, and they're a lot more expensive than resort bindings.  Though I have to say that IME Dynafits don't rip out of skis any more than resort bindings do - that one was kind of weird.  They have a mounting system and pattern very similar to resort skis.  And yeah, if you use your stuff a lot it will wear out.  rolleyes.gif

 

Why would you want a base plate for fatter skis?

Cheers Bob....I have taken a closer look at what I thought was a base plate and it is actually a front/back plate for the Low Tec bindings.  No, I am mainly an off-piste skier but have clocked a few in-bounds days on my TLT's thus far and have no complaints.  I am mainly thinking of using this set up for the slack rather than the back....my existing markers do weigh a hell of a lot so I would be keen to trim that if possible.

 

Given Dynafit now make a 115mm ski i think I can safely assume a 123mm bent chetler is not an issue.

The difference is the toes can be locked out, so it's possible to transmit a lot for force to the toe piece. I've ripped out 3 older toe pieces... and I weight in at a manly 145lbs and don't huck that much, but I think a lot of that was due to a design flaw in the FT12 toe piece.

How are you ripping the toe piece out of the ski? I can see that happening during a crash with the toes locked. If that's the case, you obviously shouldn't be locking them out. Clearly user error.

 

I've broken a toe piece on the skin track. Steep icy side hill, with a fat ski really torques the toe. The stamped metal bracket cracked. Dynafit makes a "power plate" to combat this. Basically a piece of plastic that supports the toe on the sides. The newer radicals have a different material, are thicker and have a wider mount.

 

Either way you'll be fine mounting them on BC's and if you do have an issue Dynafit will be quick to fix it.

There's a lot better chance you'll rip the toe pieces out on any binding if you mis-use it by skiing it such that it won't release.

I ripped them out while skiing or descending on hard snow with the toes NOT locked, It was obviously a problem with the FT12, thus the add on power plate..... The point is you lock the toes on the up, thus you can transmit a lot more force to the toe piece.

I've mounted Dynafit Radical St bindings on my K2 Pontoons, DPS 112RP's, and my Blizzard Bonafides, and I've never had a problem with skiing aggressively at resorts. In fact, I skied over a million vertical feet of lift served sking on my Dynafits without any problems.

 

I love being able to ski in Randonee boots all the time. They walk better and ski just as good, or better, than alpine boots. I'm skiing on the Dynafit TLT4 Carbon boots with a Intuition Powerwrap liner.

 

But I'm a light skier at about 145lbs. And while I ski fast, I don't ski switch or jump off of high cliffs.
