The 300g Touring Binding Thread

[Blaster]

Stoke for making the skin track you want on 300g bindings.

Btw, what is the modern day version of that Dynafit Low Tech heel? Something that keeps going and won't break.

Every binding has rare failures. It's hard to know the denominator as we just see the occasional failures posted online. Certainly there are more Dynafit brand bindings out there in the field than other brands therefore increasing the denominator compared to the cottage brands. We would expect a larger numerator of failures in that setting.

Toes: Dynafit Radical toes are really durable and ski well. They are also really easy to get into because of the "power towers." The original Radical toe has steel toe wings and weighs the same as a 5 hole steel toe (the old 5 hole toes are also really durable and I still ski them a lot). Newer Radical toes like in the Hoji picture above have moved to aluminum toe wings and save some weight (~30g). I only have ~100k vert of skiing on the aluminum toe wings but I like them; for my weight (~80kg) I don't foresee any durability issues but that is conjecture so far.

Heels: The Low Tech heel I pictured above has a U spring for vertical release and adjustable lateral release. Some Dynafit bindings that use a similar system are the TLT Speed, Blacklight, and the Speed Superlite 2.0. There are a lot of good heels in 2024 that use other systems too. People on this forum have reported failures presenting to shops with broken SSL 2.0 heels, but my experience is that they are as or more durable than any other heel.
Things I like about the SSL 2.0 heel:
-light weight
-easy to turn at transitions (when heels are too hard to turn [Dynafit TLT Speed!] I end up ripping holes in my liner gloves that I wear while skinning)
-only 2 height modes (low and medium, no really high riser). For my biomechanics and boot choice, it always works great and I'm not left wanting. Some people need a true flat mode but I don't.
-sealed/internal lateral release mechanism unlike i.e. ATK Trofeos. In spring conditions they don't get gunked up with pine needles and detritus from the snow surface
-low stack height, no need to shim toes
-adjustable lateral release I find helpful. I just keep turning up until I don't spin out on jump turns. I've had problems with race heels and spinning out.
-there are other downsides like no official flat mode (can sometimes leave it turned 90deg for flat, will often spin back after a while, B&D makes a add-on for this), no BSL adjustment without a plate (I use B&D plates), plastic heel housing is a theoretical concern for aging plastic, etc.

But to summarize a short answer to your question my vote is Speed Radical toes (steel or aluminum) and SSL 2.0 heels. AKA the SuperRadical.

saw the ATK RT 11 EVO today at a clinic - that was the binding they were the most proud of

website says 325 grams but the sheet they gave me today says 295 grams


toe piece has adjustable lateral release

I don’t have a lot of experience with their bindings but they look really great

I like that they are repairable

I have the RT10 Evo and they are excellent binders. I put the free ride spacer on mine and it made a big difference in edge hold. They just work, metal where it counts, and all parts seem well engineered, but not over engineered. I would definitely buy another pair.

[singlesline]

Picked up a pair of Zero G 85's off another mag with the intent to use them for basically fitness skinning the resort and local beer league skimo races (turns out my ravens are pretty sketchy bombing hardpack in the dark....) Need some lightish clamps.

I'm ATK-curious and thinking about the Crest 10, but the RT evo looks like it could be good too. Kind of hard to tell the difference between the RT11 and the 2025 Crest 10 now that the Crest 10 has magnetic risers and auto-release brakes.

Desired parameters are: brakes, bsl adjustment, lean more towards ski performance and safety than total lightweight uphill performance. Alpine DIN for me is usually happy around an 8-8.5.

Any thoughts?

The rt 11 evo has toe clamping force adjustment, call it release adjustment if you want. It’s basically a raider evo that goes to 11 and is about an ounce lighter. I would go for previous gen raiders, they’re only 315 on snowcountry right now. The new tyrolia almonte also looks promising

I was thinking the raiders were a bit overkill for the setup, but I suppose the weight difference really is pretty close.

Telemark Pyrenees has the 2025 Crest 10 for 365, but that last pair of raiders on snowcountry looks pretty good (and has the right brake width)

[ASmileyFace]

RT Evo all the way if price is no concern. That binding is legit.

Hmm, if this year's model shows up with a decent price on one of the Euro sites in the next few days., that might be the way I go. Or if BD gets anything back in stock that works with the discount code I'm sitting on.

Telemark Pyrnenees had a big ATK restock in the past week--they were down to slim pickings when I first started my binding research and now they have a bunch of models/colors/brake widths.

[Benneke10]

I would not expect BD to be carrying ATK this year, it looks like ATK is taking over their own distribution in the US

Oh?

I noticed last year they stopped doing special BD versions. They just sold them as ATK like they do with fritschi. Maybe that's why.

[~mikey b]

yeah no more BD distribution

I’ve got a potentially stupid frankenbinding question: has anyone tried mounting a gara titan toe to a plum Karibou toe plate? I think the mounting patterns are .5mm off but I’m not 100% sure.

Unfortunately don't have the answer to your question, but I have successfully reused holes in a ski, replacing Plum toes with Trab. Dynafit made toe plates that fit Trab perfectly several years ago, there are surely a few still kicking around. Aski made them for a period of time as well.

Thanks! I’ll look around for those

I haven't done that exactly, but I've mixed and matched Dynafit/Trab toes on inserts/plates and just ignored the 0.5mm difference with no ill effects. Just use some Vibratite or similar if you're not planning to routinely remove them.

Dynafit and Trab toes are both 27mm wide so they align perfectly, Plum are 26.5mm.

[skis_the_trees]

Are you sure? My recollection which Skimoco seems to back up is that the old 5 hole Dynafit toes were 30 x 26.5 for the main 4 holes. Plum is 30 x 26.5 and Trab/ATK/others are 30 x 27.

When doing a standard mount the 0.5mm is well within the error of the process even with a jig. Adjustable plates are very accommodating due to their nature i.e. adjustable track Dynafit/Aski ones. Inserts and solid plates are the least accommodating but still tolerate 0.5mm difference with ease (split between the holes, it's only 0.25mm difference aka 0.010") as long as you don't have rotational error of the position of all the holes.

You're right, I was incorrect, I mixed up the length and width. Plum, Trab, and Dynafit are all exactly 30mm wide so the track-style toe plates would work perfectly with all of them but the Plum plate would still have 0.5mm difference in the height of the binding with a Trab toe. I bet Skimo Co would test it out if you ask, they are usually very helpful with these types of things.

[PinyonJuniper5]

I have a set of the Aski toe plates that were designed to work with Speed Rad and LTR toes, and it appears that the track width would work with an ATK Trofeo toe, which (as mentioned above) is the same pattern as the Trab Titan toes. (30x27)

However, the hardware that came with the plates is too thick to pass through the screw holes of the BD Helio toes (same as ATK) that I currently have lying around.


I didn’t realize that the screw holes on a Radical toe piece were larger in diameter. That’s an interesting consideration, and it might factor in when adjusting a binding toe for alignment after mounting.

Anyone else getting instagram ads for the 5ive binding Kickstarter? https://www.instagram.com/reel/DDh6B...c4MTIwNjQ2YQ==

Slick pics and video but they avoid showing what’s going on at the toepiece. I was able to get this frame from the video:



350g for the Freeride version supposedly. :shrug:

[hick]

With that binding^^ and ATKs new hybrid coming out, what a cool time for new development in touring bindings! Love the competition!

I’ve got a pair of barely used speed turns. I shimmed the toe, but still hate them. Thinking of building a Franken bindings with the toes and plum [emoji637][emoji6[emoji640][emoji637]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji638]]] heels. What’s the collective opinion on the [emoji637][emoji6[emoji640][emoji637]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji638]]]s? Set up would be on a spring ski

So you somehow screw a threaded thing into the pinhole on your boot to slide into that c-shaped connector? Actually looking closer, there appears to be a metal piece attached across the front of the boot the has the threaded part. Looks great!

[Marshal Olson]

@Altacoup - 10+ years skiing Radical toes and Plum race heels on adjustment tracks. really no dowside on a light/pow setup IMO, unless you really like high heel elevators. If you use the K14 Kreutzpiste plate w/ a Plum 150 heel, it will drop into the back speed rad holes. Pretty sweet...
