Someone explain Dynafit bindings?

Dynafit is one brand that is known for making "tech" bindings. There are others like G3, Plum, Fritschi, and more. They are made for people who are focused on alpine touring, and only work for people who use touring boots or boots with tech inserts (If you don't know what those are then you don't have them). NOT standard alpine boots.

The way tech bindings work is that they have pins that enter holes in the boots soles, and eject laterally, instead of longitudinally like a standard alpine binding. They allow the heel to be freed when in touring mode, and the toe to hinge back and forth while still being connected to the pins. The advantages are that they are lighter than AT bindings like dukes/guardians/adrenalins, and are used for longer tours. However, they don't have the power transfer or performance of dukes/guardians/adrenalins, would not take the beating of standard resort use, only work with certain boots, are very expensive, and generally do not go up to a very high DIN (with the exception of the Dynafit Beast). They are for people who care just as much, or in some cases more, about the way up then the ride down.

Pretty much this.

The he new generation of tech bindings are getting burlier The new radical 2 and beast 14/16 are beginning to better bridge th gap. Not having a forward pressure adjustment was a factor in using them in bigger lines but has been resolved now.
They still won't be great for resort use as they still suffer from the metal on metal contact but in soft snow this is less of an issue.

This is market is one which is growing big time. Keep an eye out of new tech boots and bindings coming from some of the bigger established brands in the comin. Seasons.

if you want to go on long distance tours and ski lines get dynafit. if you want to access areas areas to build jumps and jibs get BCA trekkers. i got a pair this year and love them.

Trekkers or dynafits?

MartianManThe way tech bindings work is that they have pins that enter holes in the boots soles, and eject laterally, instead of longitudinally like a standard alpine binding.

They can definitely eject vertically at the heel and are extremely prone to doing so on switch landings, especially with the toes locked out. Not a fun experience going into instant tour mode on a switch landing! Of course tech bindings were not designed with riding switch in mind.

Tom and MartianMan pretty much summed it up. The only thing I'd add is be very leery about new model tech bindings. Several models have had issues with the original release and took a season or two for the manufacturers to work out the kinks. For example the first few plum guide generations w/ the silver toe wings or the orginal dynafit radical before they added the power towers. The radical 2.0 definitely looks to be a step in the right direction, but I wouldn't want to be a test dummy...

If you don't mind more drilling, you can also look into quiver killers. I ski on JJ's mounted up with dukes in-bounds and for slackcountry, but I bought dynafit beasts for this year and I will mount everything in with the quiver killers so I can swap the bindings out depending on the skiing I'm doing. Also plan on adding them to a second, narrower ski so I only need one binding for 2 touring skis. Adds a little bit of weight, but I'm not too concerned about it.

I 2nd the freedom binding inserts. Put a set in for normal alpine bindings and a 2nd set for your dukes/guardians/dynafits. Swapping is a breeze.

If you plan in spending 3000 dollars on some skis and bindings dynafit is your company

^^^^ wow stupid is as stupid posts
it don't take most peeps to long to realize
needlessly luggin heavy shit uphill is whack.
and the ones telling you you can't ski them inbounds or they are not durable probably never used em.
once you drink the coolaid.....

Or just buy a gaurdian or duke and dont worry about messing with differnt boot and changing bindings.

Nothing better than spending a day in Alpine Daywreckers haha.

Tech bindings FTW

Just put together a tech binding touring setup for around $800. Boots, bindings, skis, all brand new. You'd be an idiot to pay $3000

OP, it sounds like dukes and guardians are what you are looking for. Stay the fuck away from trekkers.
