Here's what others have to say...

I like 'em

  • Familiarity: I've used it several times

Used them on maybe 40-50 resort runs and on Rainier/Baker a handful of times with the GT skis. So far no issues. I wish the heel could be adjusted without bending down and cranking it, so minus 1 star. Otherwise no issues yet.

125 lb skier Sheared the Pin!

The pin on this binding sheared today when I was skiing on the groomer off Mt Hood. I had skinned up about 2500 feet to test out my new boots and do an overall shakedown for a big ski I have coming up in a couple of weeks. On the way down, I fell, not a huge fall, while turning left and so landed on my left hip. My ski released. Then, I looked at it and the pin had sheared! My shop in Seattle where I have all my mounting, bootfitting done, etc, had advised me against this binding which they said they were no longer carrying because it tends to break. I had already purchased it when they were warning me, and we agreed that so far the cases they knew of were "big guys" skiing agressively. Well, I am not big, I am 125 pounds, and I was on a groomer. And the pin sheared. So, I will be returning this to Backcountry.com and I am glad that I bought it from them, and that it broke before my big ski. I'll be using some skis with Dynafit TLT speed on my big ski and getting another set to put on these boards once I strip off the RT.

Is the rear mounting plate included with the binding (the one that allows for fore/aft adjust), and what is the adjustment range?

Responded on

I bought these and no, did not get the plate. The adjustment range is 40mm.

Posted on

I'm leaning towards getting the Dynafit Manaslu as my first AT ski. I was going to get this binding, but it looks like the 11/12 model Manaslu do have inserts therefore would be incompatible (unless I guess I'm luck enough to be able to drill additional holes to fit my boot w/this binding?). Is this the most comparable binding Dynafit makes? http://www.dynafit.com/product/bindings/low-tech-radical? I can't find anyone that sells it.

Responded on

I'd say the TLT Speed series is a bit more on the same level as the RT. The Low Techs are a bit minimal for the Manaslu and certainly more minimal than the RT.

In truth, though, you may be aiming a bit too high for a first AT setup. The Manaslu isn't exactly a randonee race ski, which is what the Low Tech and, to a lesser extent, the RT are geared toward. For a backcountry AT setup on a 95mm waisted ski that you want to (I assume) thrash in the backcountry, you'll need a substantial binding. Look a bit closer at the Verticals if you like uphill better or the Radicals if you're more of a downhill person. You'll be much happier when your bindings survive your first tour.

Nearly Rando Race Performance, Yet Full Features

The RT is just barely over the weight of my rando race bindings, yet it has independently adjustable forward and lateral release, just like my far heavier German/Austrian and French "Tech"-style bindings. Even better, it has the kind of “half-step” heel elevator position of my rando race bindings, which is perfect for optimally graded skintracks, yet it also comes with an optional elevator extension which is perfect for the steeper-than-optimal skintracks frequently required in ski mountaineering terrain. I have mine mounted straight to the ski, although if you anticipate needing to change the fore/aft position, the optional adjustment track is a pretty small weight penalty. The only drawback I can think of is if you prefer to rotate the heel by your ski pole tip, although even with my various “Tech” bindings that are designed better for that, I usually just reach down anyone with my hand.

2 follow up qs:

1 - Are these compatible with the Scarpa F1 boots? I found a pair of 31s somewhere and hoping they fit.

2 - How do these bindings compare with the Dynafit Low Tech Radical binding, which seems to be of similar weight?

Responded on

Yeah you can use the F1 with these as long as you mount them to the BSL of the boots. If you want to use them with boots of different BSLs you'll have to get the adjustment plate. In terms of comparison to the Low Tech, you get both toe and heel RV release on these whereas that is not the case on the Low Tech which have fixed values.

Responded on

What is the benefit of having both toe and heal RV release? New to skiing (well haven't skied in 15 years since switching to snowboarding).

I'll jump on the 5 star bandwagon

Great binding so far. So light. Easy to get into the front pins. I haven't figured out how to switch rear post heights with a pole on the fly (like I can with a dynafit). But that is a small price to pay for something that weighs so much less. I also broke the ski crampon holder on my very first ski trip, but I suspect that was just a manufacturing fluke. Thank you Backcountry for the quick replacement. From now on I will be a bit more delicate when it comes to putting on the ski crampons. But that is an ok tradeoff for the light weight.

Will these work on Dynafit Skis? Was looking at the Broad Peak for a super lightweight mountaineering setup. Also the Manaslus for a more all around ski. Damn these are light.

Best Answer Responded on

Yes (and no). It will work on any Dynafit skis without inserts. For fall 2012 this will be all models except the Stoke. It will not work directly with Dynafit inserts (different hole pattern), but these skis can still be drilled like any other ski.

Responded on

The Broad Peak should be fine, since that model has only the toe inserts, and the RT shares the toe pattern (sans the front center hole) with the various Dynafit models other than the new Radical. For the current and older Manaslu versions though, you might encounter some tricky problems with drilling the heel unit (i.e., overlapping issues with the inserts).

The Best

I got this setup with the Sportiva GT Alpine Touring Ski and Dynadit TLT 5 Mountains and it is INCREDIBLE. Lightweight and easy on the way up, and locked and loaded for the descent.

1. How high are the heel risers in each position on these bindings?

2. How much higher or lower is the max heel riser compared to the Dynafit TLT speed (not radical)?

3. Can you switch from flat to mid to high riser and back and forth and everything with your ski pole from a standing position, like you can with the dynafit tlt speeds?

Responded on

I dont know the tech specs that you wanted, but they are VERY easily ajusted with your ski pole

Responded on

1. "How high are the heel risers in each position on these bindings?"
2. "How much higher or lower is the max heel riser compared to the Dynafit TLT speed (not radical)?"
Elevator heights listed below are measured from top of elevator to center of toe pincers, with the “/” between the two positions. Actual imparted angle will depend on boot sole thickness, rocker, and length, i.e., don’t try to compare these numbers to non-“Tech” bindings. (Also note that Dynafit Speed comes equipped with optional 8mm spacers and attachment hardware, not reflected in these #s.)
RT: 9/34
RT when mounted on optional fore/aft adjustment plate: 14/39
Dynafit Speed: 24/51
Dynafit Vertical ST/FT: 30/57
Dynafit Radical Series: I keep forgetting to measure...
G3 Ruby/Onyx: 26/55
Plum Guide: 25/51
IMHO, the RT offers the best of both worlds: the “half-step” on rando race bindings for optimal skin tracks, the full elevator position for steeper-than-optimal skintracks, and even a “flat” position if you find yourself on endless truly flat nordic terrain.

3. "Can you switch from flat to mid to high riser and back and forth and everything with your ski pole from a standing position, like you can with the dynafit tlt speeds?"
Although you *can*, it’s not all that easy, and you run the risk of mangling the plastic elevator extension.

As a splitboarder I only need the toe pieces. Any way to buy them only?

Simply awesome

I used to have a Rossi alpine setup that I would hike up with snowshoes. It was a great setup for resort skiing but was just too heavy off piste. That total setup weighed 31 pounds. THIRTY ONE POUNDS!! With the boots, bindings, skis and snowshoes. My new setup, with the Sportiva RT Tech binding, Sportiva GT ski and Scarpa Maestrale boot weighs an astonishing 15.5 pounds. I couldn't be more psyched. The whole shebang totally outperforms my old ski in every possible way. I couldn't be happier. These bindings are absolutely sick. Uber light, the optional crampons are almost weightless, the optional adjustment plate will let friends borrow the ski or let me change boots should I decide to in the future.

Can you go from ski to skin mode(and vise versa) without taking them off? And are they truly all metal?

Responded on

The RT bindings are indeed made entirely of metal, except for the DIN setting windows. Transparent metal is just too darn expensive. You can transition from touring to ski mode without removing them. Ski to tour requires taking them off because you have to release the toe to get the heel off.

Swweet

Light and secure, with apparent true DIN. No prerelease to date. Easier entry and exit than 2010 Verticals. Very light when matched with Hi5 (orgasmic actually). Get the adjuster plate, worth it.

Not Just a Rando Race Binding!

I've been on this binding since it came out -- about a year now. I tour a lot on rando race gear, but the RT piqued my interest because it offers lots more than a normal rando race binding, and a normal tech binding for that matter: 1) it has an adjustable Release Value (note, not truly DIN satisfied); 2) it has a high position heel lift; and 3) it weighs 175 grams!! Cut some weight without any performance penalty.

Hey, so the DIN toe is the main advantage of the RT over the Dynafit TLT Vertical bindings?

Responded on

Sorry my mistake..an adjustable toe and heel but not exactly DIN.

Responded on

There is no need for a din in the toe on a tech binding because of the way the bindings are meant to release under twisting motions. So even if there was one it wouldn't be advantageous.

Responded on

The toe release could potetailly be safer. I got a spiral tib-fib fracture in my Dynafits due to the mechanism of release (although it was my own fault the bindings were not adjusted correctly). The Dynafit will release at the heel first, then the toe will relase next, in sequence. This sequencial release creates a large twisting force = spiral tibia fracture for me. I can't help but wonder if the toe had released SIMULTANEOUSLY that this might not have happened. No proof without playing with a pair, but I could see the potential benefit. I still love Dynafits.

Responded on

Also, the fact that they are all metal. cam seems to say that his dynafits caused him a tib/fib spiral fx... i'm curious if he was skiing in locked mode, and how much he weighs? I always ski locked out because I tend to fly out of dynafits if not locked out because I weigh ~200lbs. Even when locked out, I've never had a problem with them releasing in a crash, and I've never had an injury due to nonrelease. Actually, all of my bad accidents can be partly or wholly attributed to prerelease of a heel or locked toe, most of the time because of all the chintzy plastic that dynafit uses. Can't wait until I have some $$$ to pick these up, but I am interested to see what people say about skiing with these locked out... it seems that it would be a stronger lock, and may actually cause some injuries if you weren't careful.

Responded on

Just to be clear, the adjustable toe release only works if you have the toes locked. In ski mode, they release exactly the same as dynafit or other tech bindings. So unless you are skiing with the toes locked down, the adjustable release applies for the uphill. Skiing with the toes locked is still not recommended.

Best Answer Responded on

AWA, you should look into the PLUM guide binding. It has longer pins than the RT and stronger toe springs. It costs the same and if you are prereleasing from the dynafits, the RT would be worse since the pins are even shorter.
