Dude I climb trees for a living I had a piece of gear fail and cut the sheath of my rope vertically for about 12 feet the sheath was not completely cut through I was descending approximately 24 feet from the ground when it happened I got lucky I'm making a video right now for my tree bros I'll link your video in the description!
Hey Ryan- did ask Beal why they chose glue over something like a weave process? Seems to me you have all that extra thread around - weaving the sheath into the core would work better- thx
The interesting thing is that for most products, as a buyer, I'm just trying to understand the limitations. Because I don't trust the marketing. I'd rather know something is a solid 5kn, than un-independently tested 10kn.
To the Beal team: I am happy with the one Beal rope I have and trusting your product enough to let Ryan beat the shit out of it definitely makes me trust you 😉 Money well spent 👍
I have always wondered why this isn’t the standard for all ropes being used for abseiling and ascending. Seeing how it reacts in different scenarios was very interesting. Thanks Ryan.
I had never heard of unicore and seeing as I only sport climb it's probably overkill for my needs, but it's interesting, and seeing brands cooperate on these videos really makes me trust them more
Several years ago while ascending fixed lines up to Mammoth Terrace on El Cap the sheath of the rope I was on was so bleached it essentially turned to powder and I went for a slide for life down the fixed line until the sheath bunched up and I stopped. After changing my underwear I moved over to another fixed line that looked in even worse shape than the one that failed but it got me to the anchor. I stayed off any fixed lines that weren’t ones that I placed after that.
Awesome! I'd be interested in seeing unicore applied to arborist ropes. The ability to stay round is rather important when running stationary rope techniques on mechanical friction devices.
So, I totally misunderstood unicore before this video.This definitely helps me make a more informed choice given what I want to use the rope for and will mean I don't have a false sense of safety on a thin rope just because it has unicore. I really appreciate this.
Love that Beal / a manufacturer is finally working with you. I rarely comment on RUclips but had to say it. Personally I have Petzl Volta ropes (I like orange in pictures). I’ve heard good things about the joker but now they are definitely on my hit list. As always, thanks Ryan.
Absolutely love this! I’ve been a fan for a while now, and it’s great to see companies recognizing the value of your work and partnering with you. Keep up the fantastic content!
I’m not sure unicore makes the difference for me to need it in a rope, but I sure do appreciate learning more about it! Thanks for the video and huge thank you to Beal!
When you were ascending on the core, I would note that in reality, you'd hopefully have some prussiks with you and you could transition to ascending with those... Might be be another fun test one day (holding strength of klemheist/prussik on core), but yeah, I'd get the hell off of a toothed device if I were only on core strands 😅
I like Beal, a lot more now they've been so helpful with this video. It's great knowing all the theoretical stuff that their (and other brands) testing criteria meets, but this is a bit more 'real world' testing which helps understand how good the kit is when not in optimal condition. Incredible how much force can be applied with a toothed ascender in a f1.8 fall. I now trust my ropes a bit more, i have Beal half ropes but not 🦄
You mention it briefly at the end but the reason I love Beal Unicore is because if you ever coreshot your rope, you can bail quickly without having to isolate the coreshot section via alpine butterfly. As you demonstrated you will not put enough force for it to matter while rappelling.
Congratulations on the huge success. All the work that you put into each video can be seen with how you present the information clearly. I'm so glad that we can have this content here on RUclips, it really is invaluable
Awesome video as always Ryan! I'm not a climber but if I ever did I'd go Beal just bc they were open enough to test like this, wish more manufacturers were like this. 👍👍
I hadn't really considered Beal Unicore before this video, but now I am aware of it, have a good idea of its pros and cons, and have a good vibe about the manufacturer. I think I used to have a Beal rope, but I can't really remember, and right now - this video seems more relevant to me than those memories.
Another great video. I never heard of unicor until just now! And I'm super excited enough that your starting a store! I will be buying a unicorn rope from there shortly! I hope one day you have a storefront so we can roll up in there and say hi. Love all your videos especially the canyoneering ones as i am too old for much climbing these days but always up for going down!
I work and climb with Beal Unicord ropes, for me they are one of the best ropes on the market. I have two ropes that I have been using daily for more than 5 years to hoist equipment and they are top.
Idk about all unicore rope but I work In the rope access industry and we use the 11mm pmi extreme pro with a polyester sheath and unicore and it adds somewhere between 1 or 2 thousand more pounds to the working load ... I can't remember off the top of my head
I’ve been using a 9.1 joker for many years now and am quite impressed with its durability, and also have a 8.5 opera for those really light and fast objectives. Overall, I really like both ropes. Thanks for the video.
I see it this way. They're getting free testing so they can see if they can improve the product. THAT is why they wanted to work with you, because of your background and the reach you have. That says a lot of good about the company that sells the product. It's hard to find companies wanting to do that for their customer base anymore, in profit focused business.
Super awesome video! I feel bad for that tree though! That root zone is getting beat up so bad. When we build treehouses we put horse stall mats at the base to protect it.
I think Unicore for some people is an amazing tool to reduce anxiety about abrasion. for others I worry they might think it is indestructible and do things that on a normal rope they might not have. the second group of people aren't a fault of beal it happens in every industry. when cars got lane keep assist and automatic braking many people started falling asleep at the wheel because they thought it would save them in any situation. It is human nature to think that innovation makes you invincible and that is why what you are doing in indispensable.
Great information! And please do a video about the drill powered winch, even if you aren't able to sell them in your store. That tool is really interesting, and I would love to see more of what it can do.
Interesting little known fun fact for ya! - Kordas the rope manufacturer from Spain invented the sheath core connection and called it 'STABILITY' Beal saw the opportunity and quickly nabbed the idea, calling it Unicorn LOL (Unicore for the serious)
Great Video! I have always be curious about the unicore process and this was super informative. I use the 11mm Access with Unicore for work and I quite like it. The person that worked here before me knicked his rope with a chainsaw and was able to safely return to the ground (do not worry that section was retired afterward).
I mean if the rope manufacturer is working with you, go all the way. See what HardIsEasy did with Mammut and how they collaborated. I want to see the impact of rope thickness on a sharp edge IN THE WILD ON ACTUAL ROCK I would also be curious of some tangle science using normal ropes compared to unicore
Hard is easy just made a video for how to test ropes on rock edges and at the end they also show a new development from edelrid that should help with that. Sadly a unicore rope was not part of the testing. Would have loved to see how it handles in that test. ruclips.net/video/x3PMT6K0_Gg/видео.html - The Last Unsolved Problem of Climbing Ropes
Good video. Nice to have a sponsor dish out some product for what ultimately is destructive testing and get some interesting results. Side note, you didn't mention the price point comparison, might have been worth a mention. I suppose we could do our own research, but I am a little bit lazy...
I've seen many long used rappel ropes snakeskin out on one end and that is uncomfortable to many folks, maybe not a money factor for many, but good for some. I can see this being a big advantage for some environments, as well as I can see this being a plus for envions where you have a rescue rope which is normally way over sized, but unicore might give just that little extra durability on a specialist rope to make an additional cost worth while, if you can then reduce bulk. Since in many cases the "rescue" rope isn't there to be stronger, just oversized for durability. It really seems that this fits in a niche where all you need is a few more percentage points of overall performance, and it seems to do that well. The big thing for me is "soft failure" if you were in a hauling situation where you generated enough force to sheath a rope, unicore might not give you time to change your shorts, but it may well give you time to get a second rope into the system when a standard rope might have given way, or bound up a pully and made the situation far worse. Not for everyday, but certainly not a gimmick.
The rope breakage at @10:12 seems concerning. In other videos you've seen non-unicore ropes desheath at ~6kN but then the core still holds. And your core-only test held until 10. But here the unicore rope snapped entirely at 6.5kN.
I might be thinking of a different brand. But I really thought that some of inner strands would be weaved through the sheath at some interval and that was what was keeping the core and sheath from separating.
I have to say: Unicore might or might not be a safety feature for how I climb. But it would be nice to have ropes where the sheath doesn’t all bunch up around one or the other end.
Does a rope that has been stored well for a few years (5-6y) go bad, so should it be replaced? What I have found out is that a modern synthetic rope that has not been damaged or otherwise badly stored does not need to be replaced.
Any chance you could ask Beal to make some unicore Arborist ropes? I would probably switch to only using those if they existed. Edit: after hitting send, I immediately realized that they have an 11mm static unicore. I will be checking that out asap.
I haven’t seen one, but have you done one to see the forces on an anchor after a piece blows? Example: multipitch climb p2, leader takes off and clips into the highest piece of anchor in attempt to mitigate factor2, at least until gets first “real” piece in for the pitch. Say they fall on that single anchor piece, with force of idk say 2kn (or insert realistic force here) but it ultimately blows that piece. How much, if any of that 2kn is subtracted(?) from the force that will hit the remaining in tact anchor? I’d think it’d have to lessen the impact on the remaining anchor, right? Thanks!
OK, I never thought I needed this, but please show us some Velcro on Velcro slack snap. I need to know how much surface area of Velcro overlap it takes to exceed the material breaking strength.
I have a question: the majority of the tests you are taking are for static things. Can you make a video on a dynamic fall (like this one on the tree) with a grigri holdin and a climbing rope and an average weight (let's say 80 kgs) When does it break? How much force does it create? How many metres the fall is?
I’m wondering if unicore ropes in _certain other_ situations might more rapidly wear-out/fuzz-up their sheaths, by virtue of the sheath not having some shock-absorbing “give” longitudinally when the rope is very heavily loaded _also_ cross-sectionally against the rock - e.g., over a sharper edge of rock - and not just longitudinally heavily loaded. I mean, if the sheath won’t ‘give’ longitudinally in that combined-vectors situation, then it’s actually rubbing more impactfully in effect against the rock edge.
Can you test what happens if you dip normal rope in a flexible glue and let it dry before use. Does it help with sheat slippage and/or add pull strength?
So based on this, I would want to know if the adhesive bond of the unicore remains after several factor 2 falls (not on an ascender). Would it start acting like a normal rope after a few falls? Some of your tests seem to show it making the adhesive non-functional after time.
I know you had someone theorising that they rub Unicorn horns to make the rope, but looking at that glue, I think that they were thinking of a different "horn" to the one that Beal use in reality 😂😂
The most striking point in this for me was the subtle moment that a couple strands slipped out of the ascender when the sheath was stripped. They have a range of rope diameters they can work on. So the bunch of spaghetti may not break as such... but may slip out 😬
Great vidro. As usual! I always wondered how much unicore can avoid twists in a rope after longer usage. From my understanding those twists are caused by the core twisting inside the sheat, but I'm not sure if this is actually true. Would be interesting to get some info on that
We exclusively buy Unicore for our semi-static/low stretch ropes we use for mountain rescue as we often do long lowers (> 100m) which result in a lot of sheath migration on non-Unicore ropes and consequent issues with devices jamming on the excess sheath. As an aside, what was that drill powered rope winch that you were using? It looks cool!
Beal is on my wishlist now, but the really interesting thing is all the disasters that sheath failure can cause, especially on SRT rescues, etc. Image being 45 meters up on a 60m rope so if the sheath fails, you are going to deck it - the know will still be on the ground. What's the plan - a knot every 10m to protect against sheath failure due to all these fancy new toothed ascenders coming in?
GReat video as usual -- AND a great introduction to Beal ropes. How does the unicore deal with extreme temps? like from a 300M or 400M rappel on a rack which can glaze a sheath? And how oes it deal with extreme cold and wet? ice-climbing?
makes me wonder how something like Courant Ultima or Edelrid Prostatic Synctec would do where they are not glued together but braided together to make the unicore
Love my beal jokers. Run golden dry unicore 70 halfs for trad multipitch mostly at Seneca but also often at more local spots. Love the piece of mind of running 2 systems especially if the route meanders or has thin gear in spots, also that I can rap off anywhere without having to wait for anyone. :D The rocks at Seneca can be pretty rough on ropes so after this past august I wanted to reassess my methods. Pretty happy that I landed on the jokers for halfs instead of something without unicore. Im curious about the chemical qualities and applications of the glue. Say Im using these ropes 1-4 weekends a month climbing anywhere from 3-15pitches a day, plus one or two raps with my partner how long will the glue remain viable? Do whips affect its effectiveness? Would completely encapsulating the core entirely in the glue increase effectiveness/durability/longevity? Im sure it would? If the cost of the glue isnt a limiting factor why not apply more? Wonder if a certain small amount of aramid fibers could be woven into the sheaths and or cores to increase abrasion resistance without compromising a ropes dynamic quality? 🤔
So if you have enough distance between the failure point the glue near the failure just has to hold a little, just enough, so the sheath can start to act like a Chinese finger trap, biting down on the cores.
It's exciting to sell Beal ropes at our new hownot2.store/collections/beal
Look at kordas ropes they have an even better system (core sheet and a third type) then the beal ropes. All the best

You should do a golden dry vs dry vs untreated test.
I suspect the lack of slippage will reduce abrasion. Having a small fold of slack gather above a friction point will cause more wear.

I know you had someone theorising that they rub Unicorn horns to make the rope, but looking at that glue, I think that they were thinking of a different "horn" to the one that Beal use in reality 😂😂
The most striking point in this for me was the subtle moment that a couple strands slipped out of the ascender when the sheath was stripped.
They have a range of rope diameters they can work on. So the bunch of spaghetti may not break as such... but may slip out 😬
Great vidro. As usual! I always wondered how much unicore can avoid twists in a rope after longer usage. From my understanding those twists are caused by the core twisting inside the sheat, but I'm not sure if this is actually true. Would be interesting to get some info on that
Is there a video about the new tree drop tower? If not, can we get one?
Was the glue as effective after putting it in the rub master?
We exclusively buy Unicore for our semi-static/low stretch ropes we use for mountain rescue as we often do long lowers (> 100m) which result in a lot of sheath migration on non-Unicore ropes and consequent issues with devices jamming on the excess sheath. As an aside, what was that drill powered rope winch that you were using? It looks cool!
Can we get a pull test on that velco? would love to know if the velcro can hold past the breaking strength of the backing strap.
Beal is on my wishlist now, but the really interesting thing is all the disasters that sheath failure can cause, especially on SRT rescues, etc. Image being 45 meters up on a 60m rope so if the sheath fails, you are going to deck it - the know will still be on the ground. What's the plan - a knot every 10m to protect against sheath failure due to all these fancy new toothed ascenders coming in?
Excellent stuff!
Does the unicorn glue job breakdown over time? Does the softening of the rope related to the core and sheath glue bond breaking down?
The "rub master" must be a great conversation starter at parties. 😅
GReat video as usual -- AND a great introduction to Beal ropes. How does the unicore deal with extreme temps? like from a 300M or 400M rappel on a rack which can glaze a sheath? And how oes it deal with extreme cold and wet? ice-climbing?
makes me wonder how something like Courant Ultima or Edelrid Prostatic Synctec would do where they are not glued together but braided together to make the unicore
I’d love to see a rub off between the Joker and the swift protect pro.
Hey! Can you cover temporary slings on cams? Or diy resling. Thanks!
Good job!
Love my beal jokers. Run golden dry unicore 70 halfs for trad multipitch mostly at Seneca but also often at more local spots. Love the piece of mind of running 2 systems especially if the route meanders or has thin gear in spots, also that I can rap off anywhere without having to wait for anyone. :D The rocks at Seneca can be pretty rough on ropes so after this past august I wanted to reassess my methods. Pretty happy that I landed on the jokers for halfs instead of something without unicore. Im curious about the chemical qualities and applications of the glue. Say Im using these ropes 1-4 weekends a month climbing anywhere from 3-15pitches a day, plus one or two raps with my partner how long will the glue remain viable? Do whips affect its effectiveness? Would completely encapsulating the core entirely in the glue increase effectiveness/durability/longevity? Im sure it would? If the cost of the glue isnt a limiting factor why not apply more? Wonder if a certain small amount of aramid fibers could be woven into the sheaths and or cores to increase abrasion resistance without compromising a ropes dynamic quality? 🤔
my unicore rope is so old that the glue formed little balls under the sheath.. i wonder what category that is.. anyway thx for the video!
So if you have enough distance between the failure point the glue near the failure just has to hold a little, just enough, so the sheath can start to act like a Chinese finger trap, biting down on the cores.
Oh no! Abrasion!?!
