Tension slacklines without pulleys - INFINITY gear review

would you like to see how to set up a slackline without pulleys well you finally can a long slackline with the slacking of infinity watch me play with my new toy on this episode of how not to highline [Music] [Applause] hi i'm ryan jensen welcome to my gear wall laid out on a tarp because we are going to compare the infinity which is really an innovative piece of equipment get it innovative enough a slack enovate and we're going to compare it to the weight of pulleys the cost and how much force you can actually generate with this because we love dynamometers on this channel and so even though if you already slack one you just probably want to see me use this probably skip five minutes in the video because i'm going to show you for the audience who doesn't know slacklining in general how to do it a to z starting with the tree over there and uh basically how to do this start to finish so we're gonna test our pulley system today our non-pulley system with three webbings parsic from rad slacklines is a polyester low stretch two percent stretch at five kilonewtons feather pro from balanced community is five percent stretch at five kilonewtons and man on the moon from red slacklines which is 9 16 tubular webbing inside of one inch tubular webbing can't really tell but you can definitely feel it in there and that is 12 stretch so high stretch for bouncy playful stuff medium for something you can use in the park and on a high line if you're gonna buy one piece of webbing it's nice when it's in the five percent range and if you're going to set up long high lines or long slack lines low stretch is nice so you don't have to tension as much but that might not be a problem anymore so this is where i learned how to slice line this is a 50 meter gap between this tree and that one which is pretty cool on this tree i have tree pro now tree pro doesn't keep the sling from squeezing the trees so if you have soft bark um this is borderline soft bark but it's okay if you have really soft bark what you do is you have to put sticks or pvc pipes or something periodically underneath they actually have some neat tree pro coming out that uh kind of has it built in i distribute the weight but tree pro is to protect this from rubbing uh near the edges so uh it is important to protect the trees to protect our access so we don't get kicked out of parks anyways what i'm doing in this case is i'm girth hitching i just took this purple span set and went around and put inside that loop as you can see right here because i am not going to be able to hold this up on this side it is ideal if they can just kind of come together this reduces the strength about 50 percent so it takes it from 80 kilonewtons down to 40 on a webbing that breaks at 30. it doesn't matter so i girth hitched in this case and there are other ways to skin that cat which we'll cover over there i have sewn loops on my webbing always always get sewn loops on your webbing and this is a 50 meter piece which is fine for this gap you can get up to 100 meters if your slack slacklining and new and about to buy a piece and that way you don't have to extend it to do a 60 meter gap for example but don't buy anything longer than 100 meters we do segmented high lines now and honestly anything longer than 100 meters in the park is pretty sketch so you could always extend it in the park as well with a soft chuckle um or a quick link we'll show you how to do that in all the other episodes i make anyways i used a shackle in this case don't use an aluminum carabiner on slack lines in the park when the wind picks up it goes and you get a lot of cyclic loading uh above four and five kilonewtons right about five kilonewtons is a little over a thousand pounds of force four point four kilonewtons is a thousand pounds of force and that's generally what you're playing with in the park that's the range and when you fall on a high line that's about what you get when you fall off and shock load the line so four to six is what you're playing with and carabiners can handle that but if they can only handle that amount of force so many times before they get uh fatigue in the aluminum and snap and things go flying so try to use steel when you're in the park or soft shackles so this is a soft shackle we have tons of videos on this we love using them on this channel and you can put them directly in a sewn loop and you actually get full strength if you add a little piece of webbing like this ideally you would tape it in place right now i'm doing it for demonstration purposes but it will stay once i put some force on there and actually gets full strength which means it breaks in the stitching and not up here where it pinches it what's nice is if something were to fail which i don't see that happening here you don't have metal flying at you so i'm going to raise this up and we are going to go back to the other side and play with our new tension system so here on the tension side i'm gonna put this span set now these purple span sets are the skinniest round slings or span sets that you basically can buy and i think they're amazing the working load limit is one ton or eight kilonewtons you're not putting more than that on this even if you're bouncing so they're super good enough i think it's a seven to one safety ratio and slack mountain i believe has uh one of the best prices that i have found online they're out of france and even with shipping um it's very very affordable to to buy these nobody really needs the green ones the blue ones seem to be overkill i have no problem carrying these up a mountain if i'm going to do some all-natural rigging which is where you wrap this around a rock as your anchor what's nice about this tree pro is i've got these little loops in order to hold it up while i'm working on it let's wrap this around so what we're going to put on here is a line scale from linegrip.com this thing is awesome it's raid it reads up to 30 kilonewtons but it's like 80 kilo newton strong and it tells us how much force we're going to have on this slack line um if you're going to long line often it's kind of nice to have just so you know at what tension uh you learn to like things you can identify it pretty easily so in order to not have a connector on here this is a three meter or a ten foot long span set which is basically my favorite length you can always adjust them or add to them with another one so in this case what i do is i go through the eye which is really nice about these is they have a big eye and you take you go through that the loop there and then you pull through that loop and then it's secured here you lose about 50 again anything you do with ropes you're going to lose like 50 strength but that's why you have a safety ratio to work with anyways so that's all set up and then we will connect our infinity to this just to give you something to compare to if you're new to slacklining is this is how it's normally done you have a soft release pre-built this is a shackle that's aluminum from slacktivity called the kingpin i really like it because it's lightweight if you want a good shackle rather than a soft shackle the steel shackles are pretty heavy but anyways this is a web lock we'll show you how that goes which you don't need with the slackline infinity it goes in there the reason you put a soft release in is i can unravel this when i'm done in order to detention without having to re-add pulleys or other shenanigans like knives in order to get it down so then i take my webbing this is the side i'm going to walk on and it goes down the web block and this is what makes everything so different from like a ratchet kit that you would buy on amazon for starter kit is web blocks soft releases pulleys but you can only do so much with a ratchet and you can see how i can pull the tail here and this stays tight and then what you do is you pull this i don't want to pull it too tight because i'd have to release this you just pull pull pull and then you add pulley systems to this which we'll show in other videos you have to attach pulley somewhere else maybe down here and use grips and all sorts of stuff we can eliminate all of that all the pulleys and even the webblock if you don't want if you buy a sewing loop that side you don't even need to buy a web lock if you're just starting and want to use the infiniti as your go-to tensioner now the infiniti is not light but it's uh all you need so i added the mechanical advantage extender arm on there and we're going to use this luggage scale to weigh this versus all the other pulleys i brought this is 3.5 pounds which is less than 2 kilograms but i don't know the exact conversion in my head so how much does the other stuff weigh holy crap okay so this is the beefy smc 3 inch expensive ass pulleys it's like 125 bucks 125 bucks 50 bucks for the rope you don't need like a ton of rub you just reset if you need more you need a web lock like we have there you need a line grip you're pulling something as hard as you are with this you don't get to use the cheaper smaller ones and you got to have your multiplier and your teeth and steel carabiners because it's in the park just just measure it ryan it's getting heavy okay yeah 12 and a half pounds okay so that's four almost four times more for uh the strong kit so this this gives you a lot of kilonewtons on here so you don't need like four friends helping you pull so let's we'll just find out how much force we're gonna get with all these in another episode when i compare efficiencies with pulleys which i may or may not change my shirt and film right after this episode okay our next one is the slackline slackline brothers pulleys these are the original pulleys available to slackliners i bought these in 2005. loaned them to a friend and he gave them back to me last year and i was like oh my gosh so they're pretty much in the museum now balanced community still sells them and the benefit to them still is the fact that they have teeth right here in this lever so you can pull and you can eliminate the brake because the brake i forgot to add that and the cost is another 100 bucks so this is kind of the cheapest pulley system sort of except you can't really do mechanical advantage and take advantage of the brake system and they're not that efficient since it's just a pin inside of a plastic wheel versus uh ball bearing pulleys like the smc pulleys these are super good enough for some things but oh man trying to tension tubular webbing in 2005 in this park anyways this is 10 pounds and you still need a grip if you're not going to hardpoint it that means you're going to leave the pulleys in the system we tried to take the pulleys out of the system so they're rattling around when we're trying to slackline soft pointing is when you remove them you still need a web block so 10 pounds for this setup now this little guy from rad slacklines is pretty sexy if you are going to buy a pulley system this is the cutest one and it does give me pretty good mechanical advantage considering it's tiny but in order to get that mechanical advantage you got to use a a baw a big ass wheel in order to get that we'll cover pulleys later because that's not what this episode's about anyways since you do need to have a multiplier in the system even though you could use a lighter setup you still need a web lock and you can use a lighter uh line grip or in this case a snatch which is another version of a webbing clamp in order to tighten all of this so this is a pretty common setup when i actually have been coming to the park for the last year that i've owned this this is what i literally bring is this right here so this right here weighs 3.7 pounds so it weighs even with a lightweight pulley system the lightest weight basically you can buy still weighs more than this guy and this is everything you need there is one lighter system let's go over that real quick so this right here is literally the tension system that highliners use we have this this is the rolex from spider slacklines the co-owners of slacky node they're one company now and the rolex is uh something you use to slide across the high line highlining 101 course is on how not to highline.com and we have a entire course for free on how to use a high line that's already rigged and we cover all sorts of stuff about how to slide across the highline but you can also use it to tension your line which i will show you right now a little bit still need a web lock so this is all you need in order to have the exact same setup the infinity is this is pretty light and this will definitely be the lightest [Music] one it's one pound or a half a kilogram so let me kind of show you the idea of how this works because this is the most common way you can tension a line and if you are going to go highlining shortly and this is to just train for highlining this is pretty much the setup that you would want to buy this uh rear pin allows you to put the soft release built into the webblock check out our 102 course on how not to highlight.com on why i don't like that that's why i have a webblock 4.0 which is a fixed eye on the rear anyways let me show you just so you can appreciate the infinity we're going to show you the process that this that we do for this this goes on there that's a webbing clamp a line grip whatever you want to call it that goes on the rear end and the tail goes here and as you pull it it goes through the web lock up here and tensions now we are going to make another episode where you take three more of these guys and you put one over there and one here and then you pull again and you get mechanical advantage i don't want to tension this anymore because then i would have to soft release it which i'm trying to save for the next episode i'm going to film make sure you like follow and subscribe to our channel so you can see the episode that i'm gonna film later and post probably three weeks after this one now in order to get four kilonewtons to be fair you do need four of these and three friends it's pretty hard to get four kilonewtons by yourself with the setup we will find out a couple hours when i film that efficiencies of pulley systems anyways with all of this this is two pounds this is the the lightest weight setup that is commonly used and that's two pounds so that's only a pound and a half more let's start playing with it okay so you just i'm using the selectivity kingpin in order to attach this kind of fits nicely against the line scale and done before we get into this why are ratchets from trick lines the kind you're the slackline kits you typically buy from amazon why are those bad for high lines you ask well it's because the teeth the way they engage on here is not fully set if you look at the teeth on here this back plate that locks the teeth in place is shaped exactly the same shape as the teeth so there's way more engagement the other reason this can be used for highlighting is because of the anti-slip webbing lock off on the end here now ratchets you technically can get away with tie lining on a ratchet but there's things you have to know and it's too easy to screw up and if it breaks the ratchet comes flying at you and you have to mitigate that with other stuff so you can break a lot of rules it's just the general easy to explain rollers don't highlight on ratchets plus highlighting on two inch webbing sucks so especially if you want a high line you definitely want to be practicing on one inch webbing notice they don't make any 50 meter long two inch webbings out there so this can be used for highlining it is rated for 50 kilonewtons you can take this up to they say eight but um the anti-slip and everything is above what you can even put on it so even with you whipping and playing tricks and all sorts of stuff it's uh safe they've done lots of testing and we'll go over that in a little bit anyways ideally it's easier if you stick the end of the webbing in but i'll show you how to just fold the webbing in half like a webblock and stick it in after i do this that goes in the top there you pull the load through this loop is a little bit thicker so it just takes a little bit more to get it in you just push the loop in rad slackline loops are padded with some pretty thick webbing but there we go hey we did it we got the loop through so anyways that's it so then i'm going to pull all the slack through [Music] okay now that i pull my slack through it wants to slip which is how you detention it so i turn my load selector kilonewtons on i'm just going to tighten it all the way down because i want it tight and it's got a spring on there so i mean that says five kilonewtons right there once i hit five it would slip and stay at five let's find out how accurate that is neato i'm at point six kilonewtons right now i think once i ratchet that down i'm not supposed to be pre-tensioning but i pre-tensioned to 0.8 oh man that's really nice that's one i don't know if i have to really feed it wow that's really nice i'm almost at two see how much work it takes to get to two kilonewtons when you're when you're using pulleys 2.2 now i want to do keep an eye on where all this is sitting still set at five 3.5 four now this is a bowl shaped park so i don't need more than four of course we will push the limits here um otherwise i'm too high in the middle especially with uh this low stretch webbing higher stretch webbing yeah we'll see it's 3.89 when i get off it would be three kilonewtons because everything kind of settled in and then all i can need to do is just go whack a few more times and i'm back up to where i want to be now of course it's very important to lock up your tail with any web lock but especially this guy because otherwise it's just this little wheel holding it um before i do that let's see if it slips at five so this is set here at five it's not slipping yet now you don't really want it to slip and it's and the wind is making it bounce so this is what cyclic loading is this is the stuff that's bad for uh carabiners so in order to tie the tail off i pulled out this pen here that has the keeper spring balls on that side but none on that side which is interesting it goes in there like this the tail goes back inside and then this loop gets flipped over here one pin goes in this hole and one pin goes in that hole which is pretty straightforward and then you just tighten it let's see here how do you tighten this oh you just pull it all right cool that's not hard and that is bomber because the teeth are engaged they do start to deform after um gosh would they say like 20 or 30 kilonewtons that's insane so the teeth are bomber the rubber is good my load selector is good and this thing is really neat and that's the this is the most creative part i think i don't know how much work this takes to build um in theory you can just take this off but i'm tempted to leave it on if i need to readjust something i will later locked off very cool so let's slackline [Music] [Music] so long lining is scary low stretch webbing doesn't smell stretch so i was kind of high off the ground i didn't really want to fall so you try to not think about falling so you have a higher risk of falling anyways peak force was 5.62 kilonewtons while i was on it and it's settled back down to four and that is super common with this stuff but i definitely think this would be better at three because of the type of webbing it is so let's detention a little bit and see how much force we need in order to keep me just off the ground in the middle and then swap out the webbing and see how much force we need for the other ones just because i have a dyno and i'm super curious now okay i'm gonna loosen this a little bit down to two and a half kilonewtons so i added the handle back on clicked it once so i can get this a little bit looser pull the pin and in order to release it i want to have some sort of friction on there so i'll do that and then i just unspin this until till it slips so you do oh wow wow just like a soft release that's pretty cool what do we got one and a half so what i'm going to do is tighten it back up now and my device right here says 5 which has been plenty so far so i'm just add this back in pull that tight and let's see if 1.79 puts me near the middle so i am currently sitting on it and i am about that high off the ground and that is super good enough so i'd say two kilonewtons would be really nice for this little trick to pull it down is throw the span set over the top because it's that high otherwise and that's like how high i was walking with it super super tight so it's nice to know two kilonewtons does low stretch webbing and you don't even need that much of a tension system if you have that kind of uh um webbing but as you'll see with the stretchier stuff and fanny's gonna get really nice to have so a couple neat features about this is you can see that has a rubber well it's a rubber sleeve around a metal wheel and just kind of how the teeth are all designed in there and how that wheel goes together just kind of see how that spring does all the work and you can just move where those wheels are by screwing it in and out and you can see how those teeth engage at the proper angle so it gets a lot of engagement on the teeth it's a really really clever design it takes a lot of work to design and manufacture these to not sell that many uh slackline gear is is pretty hard because people who do this love it because i mean they spend a lot of work building it and not you know they're only going to sell maybe 500 or a thousand units it's not like climbing gear where you sell 100 000 carabiners after you design one so yeah i really appreciate the people that put in the work to create this kind of stuff so here's an honest gear review i still like it but damn it i had to cut off the padding off of my loop to get it back out so i'm still detention so it comes out pretty easily once you know you're done but the loop is already folded in half right which wow that was not hard but with big fat padding the extra one inch tubular uh webbing that goes over the loop was too fat to uh get past the wheels here and the spring is too strong to do it so there's really like nothing i could do i've been working on this for a while uh so i took off the padding not the end of the world um i could always velcro sleeve that if i felt like this abrasion was a risk but um not gonna do that again i did struggle to put it in so if you struggle to put it in it'll be much harder to get back out so instead i'm going to put it in like this like a web block and see how that goes [Music] okay so now i'm gonna try feather pro which is five percent stretch at five kilonewtons it's about twice a little bit more than twice as much as the other one this does have padding but it is a tighter padding so we will risk it in this case go down so it's the equivalent of flight 4 webbings if i'm not careful and paying attention stuff like this can happen but that's easy to fix so let's fix it so feather pro has pillowed edges which means there's a little extra webbing on the edges it's a little extra material so it's easier to catch but you can see here how it's cockeyed again i think it's because when you have a bow shackle like this it's cockeyed uh the device so it's important to keep this thing in line i'm going to detention this flip this around and see if it keeps it more centered but uh good troubleshooting things to know about it but to detention it and retention it is just not that big of a deal okay i flipped that around and it looks a lot straighter so i figured out what this little clip is for i think that metal part keeps the tail from getting sucked back into the up the wheel that's a 2.7 everything's still flat and straight they do have another hole right here that you can probably buy another one of these and this would go inside of it the wind makes a jiggle anyways you can get more mechanical advantage but i see a stick all natural rigging never mind okay 4.5 even the smc pulleys take a good 9 to 1 mechanical advantage in order to get that much force so 5.2 i don't think i've ever had this thing at 5.2 before definitely definitely tying this tail off folding it flat there we go taking the tail bending it back pulling it tight there we go let's see how this feels [Music] so [Music] [Music] okay uh i don't feel like i don't feel the weight in the system i have no problem leaving that embedded in the slackline it doesn't affect the feel at all so let's switch the webbing to the super stretchy man on the moon webbing so florent berthett told me to put the load strand which in this case will be this one i'm going to flip this backwards so that's the one i'm walking on i'm walking on this side needs to be against the rubber if i fold it in half florent berthett is from slack enov and he came up with this device he also came up with the enov split which if you've been following my channel at all i love the enog split so so far so good let's see how this goes so right now my loop is within one or two meters of this and i assume it's going to get sucked in so i'm going to set this up first over there a little bit more so i can get this tail further away because as long as i've got maybe four meters of tail this should be fine and not have to get this stuck in the system i'll be back so i have pulled this out and put it back in and because i had all this extra and it wasn't bad at all i just screwed up and put it um i folded it over wrong stuck it in like like a web block orientated correctly you know and um so i just fix it it's really easy to get in you just put it on there and spin the wheel as you go and it goes so anyways a neat thing is i can pull this is the part i'm walking on this is the part that contacts the rubber this is the tail and this is on the outside of the wheel so i can pull this and pre-tension and then pull this out in order to uh preserve not getting this sucked in too much i don't mind if it does it's just there's a lot of play right here so even if your loop was close um i don't think it's that big of a problem you just pull your loop away so yeah this is great so i'm going to tension this up and start ratcheting on on this and then we'll see how tying off the tail is with this much thick webbing so that is set at five kilonewtons i don't really see a reason going beyond that and yeah i'm just going to feed this tail in where we at point two wow it's just barely off the grass right now this is so slippery so i got all this to work with this is going to eventually get sucked into the top wow wow it's only a 1.5 tubular webbing sucks detention in the park this is really fun on high lines short high lines especially they're really bouncy and playful but for a long line you don't want tubular webbing or stuffed tubular webbing in this case [Music] i'm just out of three and a half this might actually keep me off the ground in the middle but i'm gonna go to four and a half or a little bit more and settle the four but uh yeah with the smc pulleys when i used to rig this on type 18 which is also extremely stretchy i would touch in the middle and i would reset full length of the rope and pull it for it took me an hour to set it up 4.6 that's a lot of stored energy i'm just going to stop right there because i'm not going to touch in the middle on that all right so right now that's two pieces of webbing because there's one inside so that's four so let's see let's see if this even fits definitely not because if i go like this [Laughter] like not at all okay so we're gonna have to modify this you just want a lot of friction if you were to highlight on this you'd have to tie the tail off or something but i could probably do that you just want the pin on this side and on this side i think i can do that sometimes you just gotta get creative definitely not recommended by the manufacturer obviously this is like the thickest webbing you can buy maybe kill bill might be thicker but that's there we go like that honestly is not going to slip like not in a dangerous way and then that i don't know i'm just going to tie that off just because that's what i'm used to doing as a highliner tying stuff off cool and we've settled at 3.8 let's see if i touch in the middle [Music] [Music] that's really hard this tight this feels like butter on a high line with low tension wow let's go see what uh the dino says so peak force is 4.8 kept me off the ground but it settled at 3.2 but it took so much more work to get it to 3.2 and i'm glad i had this to do it even though it's still a lot of work too [Music] detention tubular webbing so get a medium stretch webbing this feather pro is awesome it's why i have so much of it because i can use it for both high lining and slack lining this is a pretty cheap parsik from red slack lines is super easy to rig in the park i could almost rig it off of this system in the park if it's under 50 meters but if you're trying to go over 100 meters or up to it get 100 meter piece of this dedicated for the park so you can get it all nasty and preserve your high line to keep it as fresh and safe as possible and if you need to repair a section um the tape is just to keep that lip from grabbing things uh i sent this in to jerry machewski at balanced community and he sewed uh he basically cut it and overlapped it and we added 10 bar tacks in here which gives it full strength and i can repair my webbings so they can all be the exact same 50 meter sections for segmented high lines so now let's find out how much of a pain in the ass this is to undo something i've noticed is you can see the angle that this is with the line scale right there in order to get that on i have to pull so that's something to keep in mind before clicking it all the way back there i'm all set i do that to loosen up this pen pin comes out super easy and do i want to stick in both sure i'll just stick in the whole thing go over that untie [Music] okay just unscrew it wow i really like the idea of this so i think the trick here is i'm going to want to keep that strand managed as well not sure how i'm going to do that don't want to put my finger in there okay i feel it going it wants to bunch up right now so my difficulty with this right now is the fact it's tubular webbing and wants to scrunch up the sleeve makes for a nice slinky but uh yeah if you don't have tubular webbing it's generally a breeze i think i troubleshooted it i'm never gonna stick stuffed tubular webbing in here again but what i do is i pull that lever down just like a ratchet when you're doing it slowly pull that one back a couple notches pull that one you're basically tensioning it in reverse and then it's fine eventually it'll come out note to self never put stuff tubular webbing in an infinity yeah was that sucked anyways to give that a fair chance i'm going to use normal webbing webbing i would normally rig in the park uh and try the fold over method with this real quick and see how it goes wow it's already easier 3.7 done looks like it's supposed to so yay for parsik um let's see what detentionine is like because this was the real pain with the other stuff oh you definitely want a diverter as soon as it starts to go it's going to go fast see what i mean ah you just lift up [Music] cool so it works like it's supposed to if you use the right webbing low stretch is great medium stretch is okay and high lining you don't want to highline on a two percent stretch webbing under 50 meters it would feel like too much shock load when you whip and could hurt you so that's why i feather pro for most of my webbings just because i can use it for both so leave in the comments below what you think of this and if you would get one and what kind of problems do you think might come from it and if we can use this for highlining i think if we are far enough away from a segment this would not be a problem otherwise you'd have to use a line grip and bypass it but you kind of have to do that if you're pulling it through a web lock anyways this is amazing i highly recommend it i'm not just saying that i do like to on gear occasionally on this channel and this is not something i'm going to on because this is revolutionary for long lining makes me actually want to come out a long line i actually don't come out in long line very often because it's pain in the ass and i'd rather go highlighting and well i like highlighting but i would totally come out now and set this up a lot more often so instead of you smashing your fingers in the infinity make sure you smash those like buttons and don't forget to subscribe because i'm about to film another very interesting video cheers
