WEBVTT 00:00:00.199 --> 00:00:02.960 ah hello curious human I don't know if 00:00:02.960 --> 00:00:04.880 you ever looked into the technical 00:00:04.880 --> 00:00:07.520 specifications of a climbing rope but it 00:00:07.520 --> 00:00:10.440 does have a lot of mysterious numbers 00:00:10.440 --> 00:00:12.320 that I think are there just to confuse 00:00:12.320 --> 00:00:14.679 the new climbers and then it has a lot 00:00:14.679 --> 00:00:17.680 of seemingly obvious things like 00:00:17.680 --> 00:00:21.680 diameter length weight however if you 00:00:21.680 --> 00:00:24.119 try to measure them and I have tried 00:00:24.119 --> 00:00:26.840 that many times you will never get the 00:00:26.840 --> 00:00:30.080 numbers that are declared so I had two 00:00:30.080 --> 00:00:32.480 goals for this video the first one was 00:00:32.480 --> 00:00:35.200 to visit my nerdy friends at mamut 00:00:35.200 --> 00:00:37.520 welcome to the world of Destruction 00:00:37.520 --> 00:00:39.760 welcome to the world of Destruction she 00:00:39.760 --> 00:00:42.640 says and see how every parameter is 00:00:42.640 --> 00:00:45.320 measured in the lab and what those 00:00:45.320 --> 00:00:48.160 numbers actually mean and then I got 00:00:48.160 --> 00:00:50.360 curious is there any difference between 00:00:50.360 --> 00:00:52.879 different ropes meaning if I take 9.5 00:00:52.879 --> 00:00:55.640 from one brand and then I would take 9.5 00:00:55.640 --> 00:00:58.800 rope from the other brand will there be 00:00:58.800 --> 00:01:00.840 any difference in technical 00:01:00.840 --> 00:01:03.039 specifications or it's pretty much all 00:01:03.039 --> 00:01:05.760 the same nowadays so I ended up scraping 00:01:05.760 --> 00:01:07.159 the internet and collecting 00:01:07.159 --> 00:01:09.280 specifications of hundreds of climbing 00:01:09.280 --> 00:01:11.159 ropes and then building correlation 00:01:11.159 --> 00:01:13.280 charts between different 00:01:13.280 --> 00:01:16.840 parameters so yeah all with the goal to 00:01:16.840 --> 00:01:20.439 make you a bit of a climbing rope nerd 00:01:20.439 --> 00:01:21.960 or nerd 00:01:21.960 --> 00:01:26.520 this the Holy Bible the Holy Bible 00:01:26.520 --> 00:01:29.520 standards 00:01:30.320 --> 00:01:32.119 so you follow the Bible when you do the 00:01:32.119 --> 00:01:35.200 testing yes this is actually like um 00:01:35.200 --> 00:01:38.399 short version short version yes you even 00:01:38.399 --> 00:01:42.640 add underscores like so geeky yeah 00:01:42.640 --> 00:01:45.320 that's instead of space he just adds 00:01:45.320 --> 00:01:48.560 underscore Dash so I have here a classic 00:01:48.560 --> 00:01:50.680 report an internal report in which we 00:01:50.680 --> 00:01:52.799 have to provide numbers for a 00:01:52.799 --> 00:01:55.040 construction diameter the weight of the 00:01:55.040 --> 00:01:56.920 Corp and the weight for the sheath and 00:01:56.920 --> 00:01:58.399 then of course we we sum it up and then 00:01:58.399 --> 00:02:01.640 we get the weight per per gr per meters 00:02:01.640 --> 00:02:03.280 okay you're overloading me already let's 00:02:03.280 --> 00:02:06.079 go one by one one by one construction 00:02:06.079 --> 00:02:09.399 test construction test what is that so 00:02:09.399 --> 00:02:11.920 construction is a number that will be 00:02:11.920 --> 00:02:15.560 tested that the consumer will never 00:02:15.560 --> 00:02:17.959 see just make a 00:02:17.959 --> 00:02:20.640 pric and then 00:02:20.640 --> 00:02:22.319 I 00:02:22.319 --> 00:02:26.920 slowly let the wait in so you just put 00:02:26.920 --> 00:02:29.599 now 10 kg 10 kg and then now we should 00:02:29.599 --> 00:02:31.280 wait for a minute but in the meantime I 00:02:31.280 --> 00:02:33.120 can explain you you say Okay I want to 00:02:33.120 --> 00:02:35.599 start from here then you follow a 00:02:35.599 --> 00:02:38.440 straight line you come back to the same 00:02:38.440 --> 00:02:41.120 pattern and you do this five 00:02:41.120 --> 00:02:46.440 times one two three and five certified 00:02:46.440 --> 00:02:49.599 ruler my minute is almost done so now I 00:02:49.599 --> 00:02:53.519 can take my measurement this is 17 cm my 00:02:53.519 --> 00:02:58.800 construction will be 17 cm divid 5 34 mm 00:02:58.800 --> 00:03:00.879 this means that 00:03:00.879 --> 00:03:03.760 every 34 mm we have a repetition in the 00:03:03.760 --> 00:03:06.920 in the pattern in the pattern exactly 00:03:06.920 --> 00:03:11.159 the smaller the size that means you have 00:03:11.159 --> 00:03:16.159 more material on the same surface area 00:03:16.159 --> 00:03:18.080 so if you have more material on the same 00:03:18.080 --> 00:03:21.120 surface area it gets more 00:03:21.120 --> 00:03:25.080 stiff if it's more spread out that means 00:03:25.080 --> 00:03:29.360 the angle of the twins is a little bit 00:03:29.360 --> 00:03:31.799 more steep mhm then you have less 00:03:31.799 --> 00:03:34.280 material on the same surface area and 00:03:34.280 --> 00:03:37.760 then it's softer so are you aiming to 00:03:37.760 --> 00:03:41.080 have more material in the same or it's a 00:03:41.080 --> 00:03:43.319 balance that you're playing with you're 00:03:43.319 --> 00:03:45.480 trying to get the best hand feel for the 00:03:45.480 --> 00:03:47.640 Rope Mamud ropes for example are usually 00:03:47.640 --> 00:03:50.360 known to be a little bit stiffer so we 00:03:50.360 --> 00:03:53.000 know what kind um of construction we 00:03:53.000 --> 00:03:55.640 need to make in order to achieve this 00:03:55.640 --> 00:03:57.760 this is actually very interesting if you 00:03:57.760 --> 00:03:59.799 compare Dynamic ropes from different 00:03:59.799 --> 00:04:02.120 Brands you can feel that some of them 00:04:02.120 --> 00:04:04.799 can be very soft While others can be 00:04:04.799 --> 00:04:07.959 much stiffer unfortunately as Adriana 00:04:07.959 --> 00:04:11.000 said I was not able to find any Brands 00:04:11.000 --> 00:04:13.519 listing construction on their data 00:04:13.519 --> 00:04:16.320 sheets pel does have a property named 00:04:16.320 --> 00:04:18.919 construction but what they actually list 00:04:18.919 --> 00:04:21.600 is the number of bobbins that were used 00:04:21.600 --> 00:04:23.759 in the making of the Rope so it's a 00:04:23.759 --> 00:04:26.040 different parameter which is also very 00:04:26.040 --> 00:04:29.039 rare to find on specifications but the 00:04:29.039 --> 00:04:32.759 more B Robins used the smoother the Shi 00:04:32.759 --> 00:04:35.280 of the Rope is going to be the cubicles 00:04:35.280 --> 00:04:37.960 that make the Rope will be much smaller 00:04:37.960 --> 00:04:40.120 which creates less friction and should 00:04:40.120 --> 00:04:42.600 increase the durability of the Rope but 00:04:42.600 --> 00:04:44.560 back to the softness of the Rope 00:04:44.560 --> 00:04:49.000 personally I would like a uiaa soft test 00:04:49.000 --> 00:04:51.880 unfortunately currently we only have one 00:04:51.880 --> 00:04:55.560 test which is somewhat related next test 00:04:55.560 --> 00:04:58.120 next test it's called notability test 00:04:58.120 --> 00:05:00.199 it's part of the static rope test but we 00:05:00.199 --> 00:05:03.240 do it anyways even for our Dynamic ropes 00:05:03.240 --> 00:05:08.080 we have to do is make a simple overhand 00:05:09.400 --> 00:05:12.400 knot so they are both overhand knots 00:05:12.400 --> 00:05:14.280 they are opposite they're mirroring each 00:05:14.280 --> 00:05:19.560 other 10 kg let it sit 00:05:20.600 --> 00:05:24.080 gently for a 00:05:24.280 --> 00:05:28.720 minute we have this uh Harry Potter wand 00:05:28.720 --> 00:05:30.160 Harry Potter wand 00:05:30.160 --> 00:05:31.560 do you know any 00:05:31.560 --> 00:05:34.560 spells 00:05:35.639 --> 00:05:38.600 uh oh that would be useful for climbing 00:05:38.600 --> 00:05:40.759 yeah lift myself up to the next bolt 00:05:40.759 --> 00:05:44.360 then I gently take out I only leave the 00:05:44.360 --> 00:05:46.639 1 kilogram and now without putting 00:05:46.639 --> 00:05:49.360 pressure I need 00:05:49.360 --> 00:05:52.440 to make it go 00:05:52.440 --> 00:05:55.199 in so here is roughly 00:05:55.199 --> 00:05:59.759 seven here I go 00:06:03.639 --> 00:06:06.880 seven so notability is a ratio between 00:06:06.880 --> 00:06:10.360 rope diameter and magic wand penetration 00:06:10.360 --> 00:06:12.599 the smaller the number the softer the 00:06:12.599 --> 00:06:15.599 Rope is but it's rare to see 00:06:15.599 --> 00:06:17.919 manufacturers providing this number for 00:06:17.919 --> 00:06:20.800 dynamic ropes so if you are particular 00:06:20.800 --> 00:06:23.440 on how soft you want your rope to be 00:06:23.440 --> 00:06:26.039 unfortunately you will have to go out 00:06:26.039 --> 00:06:29.639 into the climbing shop and touch oh next 00:06:29.639 --> 00:06:32.199 one is my favorite one diameter diameter 00:06:32.199 --> 00:06:34.880 exactly I've tried to measure this so 00:06:34.880 --> 00:06:35.840 many 00:06:35.840 --> 00:06:38.840 times and it's a wild west when you 00:06:38.840 --> 00:06:43.639 measure it so show it how you arrive to 00:06:43.639 --> 00:06:47.720 9.5 okay so 9.5 9.8 I have to measure 00:06:47.720 --> 00:06:50.599 within one meter of sample of course 00:06:50.599 --> 00:06:54.000 there's always a tolerance now I get my 00:06:54.000 --> 00:06:57.800 caliper with the special flat edges oh 00:06:57.800 --> 00:07:00.879 it's a different caliper yeah 00:07:00.879 --> 00:07:03.319 now I have to take six measurements I'm 00:07:03.319 --> 00:07:06.879 not trying to squeeze to get my number 00:07:06.879 --> 00:07:09.840 but without putting pressure I need to 00:07:09.840 --> 00:07:13.759 go around and see where it's 00:07:15.280 --> 00:07:19.479 maximum it should be here 00:07:19.479 --> 00:07:23.280 10.03 and then I can turn 00:07:23.280 --> 00:07:27.440 90° 9.8 so you found the thickest point 00:07:27.440 --> 00:07:30.039 in that spot and the thinnest 00:07:30.039 --> 00:07:32.520 and you take the average of that 00:07:32.520 --> 00:07:35.039 yes then here I do the 00:07:35.039 --> 00:07:36.919 same 00:07:36.919 --> 00:07:39.000 9.84 + 00:07:39.000 --> 00:07:41.000 103 00:07:41.000 --> 00:07:44.919 9.82 so I divide everything by my six 00:07:44.919 --> 00:07:47.720 measurements then I get a 9.95 and what 00:07:47.720 --> 00:07:49.560 was it supposed to be 00:07:49.560 --> 00:07:53.240 9.8 so we are 00:07:53.240 --> 00:07:56.919 015 over yes so something to know is 00:07:56.919 --> 00:08:00.639 that by standard we have a 00:08:00.639 --> 00:08:04.479 0.2 um tolerance for the diameter so 00:08:04.479 --> 00:08:08.400 every rope I buy as a plus minus yeah to 00:08:08.400 --> 00:08:10.800 factor in the various steps of 00:08:10.800 --> 00:08:13.280 production which you cannot control down 00:08:13.280 --> 00:08:16.840 to the 0 mm so basically whatever goes 00:08:16.840 --> 00:08:21.440 on the package is plusus 0.2 mm anyway 00:08:21.440 --> 00:08:25.479 measured in preloaded way exactly so 00:08:25.479 --> 00:08:27.599 that's why pretty much every time I try 00:08:27.599 --> 00:08:31.000 to measure it is way more more mhm so no 00:08:31.000 --> 00:08:34.440 point in doing this at home well now now 00:08:34.440 --> 00:08:36.880 we know now now you know how yes but 00:08:36.880 --> 00:08:39.039 also all the samples would need to be 00:08:39.039 --> 00:08:41.719 climatized at a certain temperature and 00:08:41.719 --> 00:08:44.920 humidity percentage so we put it in that 00:08:44.920 --> 00:08:47.640 big cabinet over there which keeps 00:08:47.640 --> 00:08:51.440 23° and 50% humidity and technically 00:08:51.440 --> 00:08:53.279 this test has to be done within a 00:08:53.279 --> 00:08:56.240 certain time upon removal 1 minute to 00:08:56.240 --> 00:08:58.760 hang the 10 kg then within 1 minute you 00:08:58.760 --> 00:09:00.959 had to measure the construction within 00:09:00.959 --> 00:09:02.600 another minute you had to measure the 00:09:02.600 --> 00:09:04.560 diameter so you're running from there to 00:09:04.560 --> 00:09:07.480 here yeah I try to be fast okay and you 00:09:07.480 --> 00:09:09.720 know what always fascinates me how such 00:09:09.720 --> 00:09:12.399 a small change can make such a big 00:09:12.399 --> 00:09:15.800 difference if we compare 9.0 rope 00:09:15.800 --> 00:09:19.440 against 9.5 rope you will feel a big 00:09:19.440 --> 00:09:21.959 difference however at the same time it's 00:09:21.959 --> 00:09:26.720 only half a millim difference now we can 00:09:26.720 --> 00:09:29.839 do the weight per meter don't need this 00:09:29.839 --> 00:09:32.120 I'm going to cut on the same side of the 00:09:32.120 --> 00:09:34.399 pin I put in just to factor in that bit 00:09:34.399 --> 00:09:36.240 of 00:09:36.240 --> 00:09:40.519 H oh okay and also 00:09:42.399 --> 00:09:46.399 here so this is 1 M if you put 10 kilog 00:09:46.399 --> 00:09:50.480 yes and then here what we do is we take 00:09:50.480 --> 00:09:54.040 the core out and measure it and also as 00:09:54.040 --> 00:09:56.160 you can see this is another really 00:09:56.160 --> 00:09:59.440 precise kill if I go like this 00:09:59.440 --> 00:10:02.200 it changes so basically just little bit 00:10:02.200 --> 00:10:05.519 of wind does change the reading yes 00:10:05.519 --> 00:10:07.600 exactly now I 00:10:07.600 --> 00:10:11.399 do the sheath weight now in rope 00:10:11.399 --> 00:10:13.480 specifications you will always find 00:10:13.480 --> 00:10:16.959 combined weight per meter and shift 00:10:16.959 --> 00:10:19.279 percentage however if you want to know 00:10:19.279 --> 00:10:21.440 the total weight of your rope 00:10:21.440 --> 00:10:24.200 multiplying weight per meter by the 00:10:24.200 --> 00:10:27.399 meters which seems obvious is not going 00:10:27.399 --> 00:10:30.000 to be accurate at all so first as you 00:10:30.000 --> 00:10:33.279 saw their meter is taken from the loaded 00:10:33.279 --> 00:10:36.519 rope but also manufacturers Package 2 to 00:10:36.519 --> 00:10:39.760 3% more length of the Rope than what 00:10:39.760 --> 00:10:42.000 they declare on the package and that's 00:10:42.000 --> 00:10:44.240 done because ropes have a tendency to 00:10:44.240 --> 00:10:47.519 shrink over time so manufacturers are 00:10:47.519 --> 00:10:51.480 being nice to us by giving more of the 00:10:51.480 --> 00:10:53.680 Rope now obviously there is a clear 00:10:53.680 --> 00:10:55.920 correlation between the diameter of the 00:10:55.920 --> 00:10:58.360 rope and the weight but what is 00:10:58.360 --> 00:11:00.760 interesting is is that the variance can 00:11:00.760 --> 00:11:03.720 still be very big for example there are 00:11:03.720 --> 00:11:07.320 10 mm ropes that are lighter than some 00:11:07.320 --> 00:11:11.360 of 9.5 ropes now personally I'm not a 00:11:11.360 --> 00:11:13.600 big fan of chasing the lightest and 00:11:13.600 --> 00:11:16.399 smallest in everything but if the weight 00:11:16.399 --> 00:11:18.560 is a big factor for you you might be 00:11:18.560 --> 00:11:21.440 entertained to know that multiple Brands 00:11:21.440 --> 00:11:24.000 claim to have the lightest double rope 00:11:24.000 --> 00:11:27.519 on the market next test next test shift 00:11:27.519 --> 00:11:32.360 slippage shift so now exactly so this is 00:11:32.360 --> 00:11:35.000 your favorite room in summer for sure 00:11:35.000 --> 00:11:38.200 when it's really hot so now this end is 00:11:38.200 --> 00:11:41.000 open and this one is sealed cuz I cut it 00:11:41.000 --> 00:11:42.760 with the heat cutter now I can explain 00:11:42.760 --> 00:11:45.480 you what this 00:11:45.959 --> 00:11:49.440 is exactly this very simple let's call 00:11:49.440 --> 00:11:52.440 it machine is defined uh this machine is 00:11:52.440 --> 00:11:53.320 called 00:11:53.320 --> 00:11:55.959 machine no it's called shift slippage 00:11:55.959 --> 00:12:00.320 machine oh sh shift shift she slippage 00:12:00.320 --> 00:12:02.399 machine exactly so what we're going to 00:12:02.399 --> 00:12:05.399 do here we have this uh three 5 kilogram 00:12:05.399 --> 00:12:08.360 weights and we're going to engage them 00:12:08.360 --> 00:12:10.399 so now this one is pulling this one is 00:12:10.399 --> 00:12:13.279 pulling and this one is pulling so now 00:12:13.279 --> 00:12:17.480 in here we have three standardized bolts 00:12:17.480 --> 00:12:19.320 and they're pulling on three Direction 00:12:19.320 --> 00:12:21.160 different directions so one is pulling 00:12:21.160 --> 00:12:23.480 this way this one is pulling this way 00:12:23.480 --> 00:12:26.000 this one is pulling down mhm what I have 00:12:26.000 --> 00:12:29.240 to do I have to pull it until the end 00:12:29.240 --> 00:12:31.680 comes within this marks that's why I 00:12:31.680 --> 00:12:34.440 have my uh my mirror here so I can check 00:12:34.440 --> 00:12:36.800 so I can 00:12:36.800 --> 00:12:39.399 start and it has to be a continuous 00:12:39.399 --> 00:12:42.399 speed and I'm 00:12:42.399 --> 00:12:46.240 there so you pulled the rope with some 00:12:46.240 --> 00:12:49.920 pressure from three sides towards the 00:12:49.920 --> 00:12:52.639 Rope 00:12:52.639 --> 00:12:56.560 yes and now you reset and pulling again 00:12:56.560 --> 00:13:01.120 yes and I have to do this five times 00:13:03.399 --> 00:13:07.560 so it's basically rope squeezer yeah 00:13:07.560 --> 00:13:09.880 number 00:13:09.880 --> 00:13:12.320 five as you see I've never touched this 00:13:12.320 --> 00:13:14.600 part right I was always pulling and 00:13:14.600 --> 00:13:17.199 pushing from this part now I slide it 00:13:17.199 --> 00:13:18.120 back 00:13:18.120 --> 00:13:20.639 again you're talking like a magician you 00:13:20.639 --> 00:13:23.839 know of course Pini as you see nothing 00:13:23.839 --> 00:13:26.440 happens here and now look Poof 00:13:26.440 --> 00:13:29.720 Magic now you can actually see 00:13:29.720 --> 00:13:33.320 here exactly where we had our Mark the 00:13:33.320 --> 00:13:35.560 shei hasn't moved he really sounds like 00:13:35.560 --> 00:13:36.839 a magician 00:13:36.839 --> 00:13:40.760 now you want some some poof trick number 00:13:40.760 --> 00:13:43.279 one I know this is actually something I 00:13:43.279 --> 00:13:46.360 I really really like uh shift slip is 00:13:46.360 --> 00:13:49.240 zero that's why we declare zero so what 00:13:49.240 --> 00:13:54.959 you could expect usually is to have your 00:13:54.959 --> 00:13:58.560 core to be now it's just out and then 00:13:58.560 --> 00:14:01.800 you would have to measure like this this 00:14:01.800 --> 00:14:06.000 will be 6.77 mm and this we will call 00:14:06.000 --> 00:14:09.959 minus 6.7 cuz it goes out so what I had 00:14:09.959 --> 00:14:12.720 happened where I cut the rope even 00:14:12.720 --> 00:14:14.839 though I burn the end but maybe I don't 00:14:14.839 --> 00:14:17.959 burn it very well and I go climbing and 00:14:17.959 --> 00:14:20.720 sometimes some of the core starts coming 00:14:20.720 --> 00:14:25.199 out is this related to this yes so with 00:14:25.199 --> 00:14:27.000 this rope which is declared as zero 00:14:27.000 --> 00:14:30.480 sheep slippage the core would not start 00:14:30.480 --> 00:14:32.880 coming out of the if one end is sealed 00:14:32.880 --> 00:14:36.240 if one end is sealed and if both ends 00:14:36.240 --> 00:14:39.519 were cut then the core is free to move 00:14:39.519 --> 00:14:41.680 it's like a snake in a tube it just goes 00:14:41.680 --> 00:14:43.440 back and forth if you wants I've done 00:14:43.440 --> 00:14:45.600 this many times I still sometimes find 00:14:45.600 --> 00:14:48.079 it difficult to burn the end well you 00:14:48.079 --> 00:14:50.160 might burn a little bit and it's there 00:14:50.160 --> 00:14:52.360 is still visibly big holes then you 00:14:52.360 --> 00:14:54.399 start burning more then it all goes on 00:14:54.399 --> 00:14:57.880 fire and then the big Clump happens well 00:14:57.880 --> 00:15:00.600 what I do sometimes times but this is 00:15:00.600 --> 00:15:03.079 you hit the knife no I I use I use a 00:15:03.079 --> 00:15:04.720 stove you make it really hot and then 00:15:04.720 --> 00:15:06.920 try to tension it as much as much as 00:15:06.920 --> 00:15:10.759 possible and use bars going through the 00:15:10.759 --> 00:15:13.040 you know the gas burning use that one as 00:15:13.040 --> 00:15:16.880 a knife oh so it it it will look like 00:15:16.880 --> 00:15:20.320 this and then you have that fume of 00:15:20.320 --> 00:15:23.360 plastic coming out of your stove for how 00:15:23.360 --> 00:15:26.399 many days that's not safe maybe because 00:15:26.399 --> 00:15:28.399 you're burning plastic but this is not a 00:15:28.399 --> 00:15:31.759 m Cor recommendation this is a a 00:15:31.759 --> 00:15:33.839 recommendation okay now when it comes to 00:15:33.839 --> 00:15:36.839 shift slippage unfortunately not all the 00:15:36.839 --> 00:15:39.360 brands list that information on their 00:15:39.360 --> 00:15:42.360 websites and in some cases they list 00:15:42.360 --> 00:15:44.639 only on some of the ropes so if it's 00:15:44.639 --> 00:15:47.000 zero they list zero if it's not zero 00:15:47.000 --> 00:15:49.120 then who knows and according to the 00:15:49.120 --> 00:15:51.079 standard this information should be on 00:15:51.079 --> 00:15:53.600 the packaging however if you're shopping 00:15:53.600 --> 00:15:57.079 online then good luck knowing now we 00:15:57.079 --> 00:15:59.120 have to do static elongation so these 00:15:59.120 --> 00:16:01.959 are reflected tapes and I'm putting it 00:16:01.959 --> 00:16:05.000 just a little bit above my clamps one at 00:16:05.000 --> 00:16:09.720 the bottom one here at the top now sorry 00:16:09.720 --> 00:16:12.639 I go in only while the machine is not 00:16:12.639 --> 00:16:15.560 running just because I have to play with 00:16:15.560 --> 00:16:20.040 lasers of course exactly I can 00:16:20.759 --> 00:16:23.160 start only while the machine is not 00:16:23.160 --> 00:16:24.440 running 00:16:24.440 --> 00:16:27.560 instead so it went into a pre-tension 00:16:27.560 --> 00:16:30.480 phase and now I need to check that the 00:16:30.480 --> 00:16:34.199 laser is actually in place so I read the 00:16:34.199 --> 00:16:35.639 first one because you saw it stopped and 00:16:35.639 --> 00:16:38.759 beep and blinked now we'll reach the top 00:16:38.759 --> 00:16:41.759 one and blink 00:16:44.880 --> 00:16:47.880 again let's just close this 00:16:47.880 --> 00:16:50.839 one so as you can see the the lasers are 00:16:50.839 --> 00:16:53.680 going up ah so your markers are going up 00:16:53.680 --> 00:16:55.360 and the lasers keep following them 00:16:55.360 --> 00:16:58.480 exactly and we have our holding time of 00:16:58.480 --> 00:17:01.240 3 minutes and it keeps holding exactly 00:17:01.240 --> 00:17:03.880 80 kg as the Rope is relaxing it keeps 00:17:03.880 --> 00:17:06.360 pulling more that's why you can see here 00:17:06.360 --> 00:17:09.480 D L elongation of the sample compared to 00:17:09.480 --> 00:17:11.520 the starting position yeah see it keeps 00:17:11.520 --> 00:17:14.079 increasing so if I stand here and the 00:17:14.079 --> 00:17:15.799 laser misses the marker it shines 00:17:15.799 --> 00:17:18.280 straight to my eyes yeah and then you 00:17:18.280 --> 00:17:21.319 get to stay home from 00:17:22.600 --> 00:17:26.039 work I just smiling saying 00:17:26.039 --> 00:17:29.360 thisas okay so machine completely 00:17:29.360 --> 00:17:32.760 relaxed yes and your lasers went down 00:17:32.760 --> 00:17:36.039 yes and you got the results 00:17:36.039 --> 00:17:38.919 5.71% so static elongation is basically 00:17:38.919 --> 00:17:41.600 imitating you sitting in the Rope or 00:17:41.600 --> 00:17:43.880 taking a top rope fall and for most 00:17:43.880 --> 00:17:47.360 dynamic ropes it's between 5 to 10% 00:17:47.360 --> 00:17:50.600 where 10% is the maximum allowed by the 00:17:50.600 --> 00:17:53.360 standards let's say you want to top rope 00:17:53.360 --> 00:17:56.760 a 30 m long route and the climber takes 00:17:56.760 --> 00:17:59.720 a fall close to the ground so so we have 00:17:59.720 --> 00:18:02.840 total 60 M of rope in the system Let's 00:18:02.840 --> 00:18:05.000 ignore all the potential zigzags 00:18:05.000 --> 00:18:07.120 friction and maybe slack and let's say 00:18:07.120 --> 00:18:09.919 that we are using a rope with 5% of 00:18:09.919 --> 00:18:12.840 static elongation so such Fall Would 00:18:12.840 --> 00:18:16.200 stretch the Rope for 3 m but if our 00:18:16.200 --> 00:18:19.440 static elongation would be closer to 10% 00:18:19.440 --> 00:18:22.640 then the fall or the stretch would be up 00:18:22.640 --> 00:18:25.880 to 6 M and that would be really bad for 00:18:25.880 --> 00:18:28.280 top roping with such rope at the same 00:18:28.280 --> 00:18:30.440 time it would also be a bad rope for 00:18:30.440 --> 00:18:32.679 projecting cuz every time you would pull 00:18:32.679 --> 00:18:34.679 on the Rope you would be just stretching 00:18:34.679 --> 00:18:37.000 it like a rubber band but I'm going to 00:18:37.000 --> 00:18:39.880 come back to this topic after we see how 00:18:39.880 --> 00:18:43.240 Dynamic elongation and impact force is 00:18:43.240 --> 00:18:46.960 measured so so yes welcome to the fancy 00:18:46.960 --> 00:18:49.480 drop tower exactly super fancy that it's 00:18:49.480 --> 00:18:52.120 all kind of automatic I see it's doing 00:18:52.120 --> 00:18:54.559 its thing and you're doing nothing yeah 00:18:54.559 --> 00:18:56.080 yeah yeah besides running up and down 00:18:56.080 --> 00:18:57.280 the 00:18:57.280 --> 00:19:00.320 stairs so now basically just went up 00:19:00.320 --> 00:19:03.159 checked all the positions now I have to 00:19:03.159 --> 00:19:04.799 tie in the 00:19:04.799 --> 00:19:09.720 sample secure it one two so there is no 00:19:09.720 --> 00:19:11.960 knot at this end 00:19:11.960 --> 00:19:14.840 no ah so it's friction but in the end 00:19:14.840 --> 00:19:17.840 there is still some kind of clamp yes 00:19:17.840 --> 00:19:19.320 and what we do here with these three 00:19:19.320 --> 00:19:22.360 turns is to not have the force of the 00:19:22.360 --> 00:19:25.480 Fall absorb here yeah it would break it 00:19:25.480 --> 00:19:26.919 that spot exactly it would just 00:19:26.919 --> 00:19:29.000 basically choke it and cut it so our 00:19:29.000 --> 00:19:31.840 goal here is to simulate a really high 00:19:31.840 --> 00:19:33.559 factor fall for example you're 00:19:33.559 --> 00:19:35.600 multipitch climbing and you start off 00:19:35.600 --> 00:19:37.120 you always you know back up at the 00:19:37.120 --> 00:19:38.640 anchor cuz you don't want to fall 00:19:38.640 --> 00:19:40.720 directly into the blade device so this 00:19:40.720 --> 00:19:43.600 is your blade device then the Rope goes 00:19:43.600 --> 00:19:47.760 to the anchor and then you take 2 m and 00:19:47.760 --> 00:19:50.720 a half yeah more or less and then you 00:19:50.720 --> 00:19:53.919 climb all the way above it yeah and you 00:19:53.919 --> 00:19:57.640 take a massive whipper and you are a 00:19:57.640 --> 00:20:03.840 still Monas of 70 kg 80 80 kg steel Mass 00:20:03.840 --> 00:20:06.679 falling in in a in a freeway there's no 00:20:06.679 --> 00:20:09.039 friction you don't slam in the wall so 00:20:09.039 --> 00:20:11.360 it's falling 00:20:11.360 --> 00:20:14.760 vertically I am it's preloading what 00:20:14.760 --> 00:20:17.360 what just happened we tied the top I did 00:20:17.360 --> 00:20:19.760 an eight knot at the bottom and now we 00:20:19.760 --> 00:20:21.799 are elongating the Rope 80 kg are 00:20:21.799 --> 00:20:23.720 sitting in the rope and just you know 00:20:23.720 --> 00:20:26.520 okay so before the drop it's already 00:20:26.520 --> 00:20:29.000 elongating for one minute I usually say 00:20:29.000 --> 00:20:31.480 that this kind of activates the 00:20:31.480 --> 00:20:34.640 Rope my minute was gone and now it's 00:20:34.640 --> 00:20:37.120 going back 00:20:37.120 --> 00:20:40.480 up opening again the clamps because now 00:20:40.480 --> 00:20:43.120 we need to calibrate to measure the 00:20:43.120 --> 00:20:46.840 exact length so at first you put some 00:20:46.840 --> 00:20:49.720 weight on the Rope so it stretches to 00:20:49.720 --> 00:20:53.440 certain degree yeah and only then you 00:20:53.440 --> 00:20:57.440 are calibrating the length yeah so now I 00:20:57.440 --> 00:20:59.880 put this two 00:20:59.880 --> 00:21:03.720 then I let 10 kg 00:21:03.720 --> 00:21:07.240 in so by doing this we make sure that 00:21:07.240 --> 00:21:09.760 from here to there there will always be 00:21:09.760 --> 00:21:12.520 the same sample length but it's not like 00:21:12.520 --> 00:21:15.480 I am pulling here to to get it as tight 00:21:15.480 --> 00:21:17.159 as possible and then comes another 00:21:17.159 --> 00:21:19.080 tester and they maybe pull a little bit 00:21:19.080 --> 00:21:22.080 more than me a little bit less then here 00:21:22.080 --> 00:21:24.919 I'm just basically doing a mark with my 00:21:24.919 --> 00:21:27.080 adding 3,000 and I'm not sponsored by 00:21:27.080 --> 00:21:29.440 adding but it's just this is the marker 00:21:29.440 --> 00:21:30.880 that you need to use for your ropes cuz 00:21:30.880 --> 00:21:32.600 it doesn't hurt them it's very important 00:21:32.600 --> 00:21:36.279 to Mark the Spot to see that the Rope 00:21:36.279 --> 00:21:37.840 remained in the same position because if 00:21:37.840 --> 00:21:39.720 it would slip somehow then you would 00:21:39.720 --> 00:21:43.600 always deliver more or new material to 00:21:43.600 --> 00:21:46.200 the deflection Edge you would get ah cuz 00:21:46.200 --> 00:21:48.440 you are trying to hit always exactly the 00:21:48.440 --> 00:21:50.919 same spot in every fall yeah if you have 00:21:50.919 --> 00:21:52.840 a rope slippage in the clam then it's 00:21:52.840 --> 00:21:54.799 enough un 00:21:54.799 --> 00:21:57.840 result so now what it's hanging again 00:21:57.840 --> 00:22:00.320 now it's hanging again again and I 00:22:00.320 --> 00:22:01.720 thought you just going to drop and 00:22:01.720 --> 00:22:05.279 that's it but like entire preparation 00:22:05.279 --> 00:22:07.159 procedure and now this is actually the 00:22:07.159 --> 00:22:08.960 most important part because after this 00:22:08.960 --> 00:22:12.080 one we will read exactly the SLE sample 00:22:12.080 --> 00:22:14.159 length so the the machine takes a 00:22:14.159 --> 00:22:17.480 measurement of the length yes down to 00:22:17.480 --> 00:22:19.720 the 01 00:22:19.720 --> 00:22:25.480 mm so now it's just going to go Kaboom 00:22:27.120 --> 00:22:31.120 yes oh man that's a big whipper on 00:22:31.120 --> 00:22:35.679 this like okay so now this is our rope 00:22:35.679 --> 00:22:38.159 as you see yeah it's like completely 00:22:38.159 --> 00:22:40.440 going up you see there's no more there's 00:22:40.440 --> 00:22:42.840 no stretch right okay so pretty much 00:22:42.840 --> 00:22:44.960 every all the rope that you had is going 00:22:44.960 --> 00:22:47.559 up there 00:22:53.480 --> 00:22:57.799 yes wow that is like still a big bang 00:22:57.799 --> 00:22:58.960 big bang 00:22:58.960 --> 00:23:00.720 yeah imagine when it rips then it's a 00:23:00.720 --> 00:23:05.000 real big bang so we had a 30% elongation 00:23:05.000 --> 00:23:07.360 and Max Force was 00:23:07.360 --> 00:23:10.240 8.85 K all right let's start with 00:23:10.240 --> 00:23:12.640 elongation I thought that a stretchy 00:23:12.640 --> 00:23:15.159 rope is a stretchy rope meaning that if 00:23:15.159 --> 00:23:17.919 it has high static elongation it should 00:23:17.919 --> 00:23:20.840 have high Dynamic elongation and while 00:23:20.840 --> 00:23:23.760 there is a correlation at the same time 00:23:23.760 --> 00:23:26.120 there are ropes with high Dynamic 00:23:26.120 --> 00:23:29.080 elongation but low static and there are 00:23:29.080 --> 00:23:32.120 ropes with high static elongation but 00:23:32.120 --> 00:23:33.279 low 00:23:33.279 --> 00:23:37.360 Dynamic interesting and actually what it 00:23:37.360 --> 00:23:40.799 is really interesting to see is this 00:23:40.799 --> 00:23:46.480 one that wasn't there 20 cm maybe 15 cm 00:23:46.480 --> 00:23:50.799 yeah of just you know elongated rope now 00:23:50.799 --> 00:23:53.559 we have a 5 minute waiting time and a 00:23:53.559 --> 00:23:56.039 little bit of this elongation will go 00:23:56.039 --> 00:24:01.520 back into place mhm but uh some part uh 00:24:01.520 --> 00:24:04.480 will stay let's say stressed forever now 00:24:04.480 --> 00:24:06.440 the second parameter we got from the 00:24:06.440 --> 00:24:09.799 first drop is the impact Force which 00:24:09.799 --> 00:24:12.159 according to the standard should not 00:24:12.159 --> 00:24:15.679 exceed 12 kons but most ropes nowadays 00:24:15.679 --> 00:24:19.360 will be between 7 and 1 half to 9 kons 00:24:19.360 --> 00:24:22.279 anyways however Bill stood out with a 00:24:22.279 --> 00:24:25.279 lot of low impact ropes so I was 00:24:25.279 --> 00:24:29.240 wondering why and the answer Bec visible 00:24:29.240 --> 00:24:33.159 once I plot elongation versus impact 00:24:33.159 --> 00:24:35.679 Force turns out they make much 00:24:35.679 --> 00:24:38.640 stretchier ropes so if you make a rope 00:24:38.640 --> 00:24:40.840 which stretches more obviously that 00:24:40.840 --> 00:24:44.039 helps to reduce the impact Force however 00:24:44.039 --> 00:24:46.679 as I already explained more stretch is 00:24:46.679 --> 00:24:49.440 not always better so a perfect rope 00:24:49.440 --> 00:24:52.399 should minimize both elongation and the 00:24:52.399 --> 00:24:55.279 impact Force now since I have this huge 00:24:55.279 --> 00:24:58.559 database of rope specs I got curious so 00:24:58.559 --> 00:25:00.600 which ropes do have the lowest 00:25:00.600 --> 00:25:04.080 elongation and impact Force combined I 00:25:04.080 --> 00:25:07.000 filtered out all super skinny and super 00:25:07.000 --> 00:25:09.600 thick ropes since I don't like them and 00:25:09.600 --> 00:25:11.880 voila a list of ropes with the best 00:25:11.880 --> 00:25:14.600 Dynamic properties on 00:25:14.600 --> 00:25:16.840 paper now are you going to feel the 00:25:16.840 --> 00:25:21.480 difference if your rope is 10 to 20% 00:25:21.480 --> 00:25:24.039 softer would be interesting to do maybe 00:25:24.039 --> 00:25:26.760 some human testing to figure out but the 00:25:26.760 --> 00:25:29.440 big elephant in the crack is that all of 00:25:29.440 --> 00:25:31.840 those specs are taken from the first 00:25:31.840 --> 00:25:34.799 fall only who knows how all of these 00:25:34.799 --> 00:25:36.600 ropes are going to perform after 00:25:36.600 --> 00:25:39.799 hundreds of Falls maybe softer ropes are 00:25:39.799 --> 00:25:41.799 going to lose their Dynamic properties 00:25:41.799 --> 00:25:44.559 even faster unfortunately at the moment 00:25:44.559 --> 00:25:46.640 there is nothing in the standards that 00:25:46.640 --> 00:25:49.279 would test long-term performance of 00:25:49.279 --> 00:25:52.120 climbing ropes which is 00:25:52.120 --> 00:25:54.919 sad so 00:25:54.919 --> 00:25:58.399 UAA but let's continue with our tests 00:25:58.399 --> 00:26:02.960 after five minutes rest we have another 00:26:05.399 --> 00:26:08.919 drop and this rest drop process is 00:26:08.919 --> 00:26:12.399 repeated until the Rope finally breaks 00:26:12.399 --> 00:26:14.440 you already see this is like a super 00:26:14.440 --> 00:26:16.799 harsh condition this is something that 00:26:16.799 --> 00:26:20.840 even in reality is hard to replicate and 00:26:20.840 --> 00:26:23.600 then in this s scenario we do this drop 00:26:23.600 --> 00:26:26.120 over and over again only with a break of 00:26:26.120 --> 00:26:28.600 5 minutes in between drops so the Rope 00:26:28.600 --> 00:26:31.360 doesn't really have time to recover and 00:26:31.360 --> 00:26:34.039 what you also need to think about that 00:26:34.039 --> 00:26:36.799 you're dropping into the exact same 00:26:36.799 --> 00:26:39.760 position each each time so the number of 00:26:39.760 --> 00:26:41.559 how many of these false the rope with 00:26:41.559 --> 00:26:43.799 stood is written on the packaging and 00:26:43.799 --> 00:26:46.120 that number is there mainly to confuse 00:26:46.120 --> 00:26:48.720 the new climbers into thinking that you 00:26:48.720 --> 00:26:52.279 can only fall for let's say five FS but 00:26:52.279 --> 00:26:54.679 in reality we never achieve such hard 00:26:54.679 --> 00:26:57.279 Falls and you can fall for hundreds of 00:26:57.279 --> 00:26:59.679 times before the ends of your Rob starts 00:26:59.679 --> 00:27:02.919 to wear down also while on average fer 00:27:02.919 --> 00:27:06.200 robes do have higher UIA full rating 00:27:06.200 --> 00:27:08.520 some brands use bare minimum of five 00:27:08.520 --> 00:27:12.240 Falls even for their beefy ropes so as 00:27:12.240 --> 00:27:15.120 it stands for now this fall rating is 00:27:15.120 --> 00:27:18.600 only an indicator that your rope is safe 00:27:18.600 --> 00:27:22.240 rather than how long is it going to be 00:27:22.240 --> 00:27:26.600 safe next test uiaa water test same 00:27:26.600 --> 00:27:28.520 setup as before for the shift slippage 00:27:28.520 --> 00:27:30.039 same machine the only thing that we're 00:27:30.039 --> 00:27:32.039 going to change here is that we're 00:27:32.039 --> 00:27:33.880 putting new bolts every single sample 00:27:33.880 --> 00:27:36.840 that we do so it's a onetime use product 00:27:36.840 --> 00:27:39.480 unfortunately not very sustainable but 00:27:39.480 --> 00:27:41.640 if you wouldn't do it the inside of the 00:27:41.640 --> 00:27:43.320 bolts would change over time because of 00:27:43.320 --> 00:27:45.080 the abration of the Rope so these are 00:27:45.080 --> 00:27:47.159 some of the the used ones so it's full 00:27:47.159 --> 00:27:50.080 of fibers so the Rope goes through the 00:27:50.080 --> 00:27:52.880 bolt yes and then as before you have 00:27:52.880 --> 00:27:55.760 three bolts one gets pulled down this 00:27:55.760 --> 00:27:57.760 one gets pulled this way and this one 00:27:57.760 --> 00:27:59.880 gets pulled this way one goes that way 00:27:59.880 --> 00:28:01.600 one goes that way and one go this one 00:28:01.600 --> 00:28:04.279 goes down so now you and I have to pull 00:28:04.279 --> 00:28:06.440 this back and forth oh and and me as 00:28:06.440 --> 00:28:08.399 well yeah of course how do you do this 00:28:08.399 --> 00:28:11.159 alone I just run back and forth so I 00:28:11.159 --> 00:28:14.919 pull yeah oh W try to keep it as level 00:28:14.919 --> 00:28:18.840 as possible stop and now follow 00:28:18.840 --> 00:28:20.480 me 00:28:20.480 --> 00:28:24.519 yeah this is a warm up for 00:28:24.600 --> 00:28:30.120 climbing know what would be funny m 00:28:31.650 --> 00:28:34.360 [Laughter] 00:28:34.360 --> 00:28:36.559 I expected 00:28:36.559 --> 00:28:40.480 it so now we have more fluffy rope yeah 00:28:40.480 --> 00:28:42.919 and we do this to simulate a a rope in 00:28:42.919 --> 00:28:45.200 normal use we do not want to do this 00:28:45.200 --> 00:28:47.480 water test on a brand new rope because 00:28:47.480 --> 00:28:50.039 it would not be 00:28:50.159 --> 00:28:54.080 realistic and then oh the fumes are 00:28:54.080 --> 00:28:58.880 delicious now 24 hours 23 00:28:58.880 --> 00:29:01.640 50% humidity another time sensitive 00:29:01.640 --> 00:29:04.840 Endeavor yes so now I'm going to take a 00:29:04.840 --> 00:29:08.720 sample the one you and I prepared 00:29:12.170 --> 00:29:14.240 [Music] 00:29:14.240 --> 00:29:17.519 yesterday let's 00:29:19.240 --> 00:29:23.080 go basically it is important to to be 00:29:23.080 --> 00:29:30.039 fast on this one okay so put my C in 00:29:30.799 --> 00:29:32.360 and I make sure that there's water 00:29:32.360 --> 00:29:36.760 running on top of it now I start my time 00:29:36.760 --> 00:29:40.559 I'm checking the water flow per minute 00:29:40.559 --> 00:29:43.399 so it is not submerging the Rope 00:29:43.399 --> 00:29:46.600 completely under water 2 L per minute 00:29:46.600 --> 00:29:49.399 plus - 02 and then the water is running 00:29:49.399 --> 00:29:52.720 on top of our fuzzy prepared rope and 00:29:52.720 --> 00:29:54.080 you see here it's really important that 00:29:54.080 --> 00:29:56.559 your ends are sealed otherwise the water 00:29:56.559 --> 00:29:59.039 will just you know go in 00:29:59.039 --> 00:30:03.080 rather than stay outside with a dry 00:30:03.080 --> 00:30:05.519 treatment it looks like the end of the 00:30:05.519 --> 00:30:07.320 Rope is pissing a little bit yeah a 00:30:07.320 --> 00:30:09.600 little bit and it's going to take now 15 00:30:09.600 --> 00:30:11.760 minutes so we can 15 minutes we can go 00:30:11.760 --> 00:30:13.399 for a 00:30:13.399 --> 00:30:16.120 coffee okay now our 15 minutes are done 00:30:16.120 --> 00:30:20.159 I need to take it off place here and 00:30:20.159 --> 00:30:23.240 just drop 00:30:23.240 --> 00:30:26.840 it that is funny three times that is 00:30:26.840 --> 00:30:29.960 very funny change 00:30:31.039 --> 00:30:32.360 do the 00:30:32.360 --> 00:30:37.720 same on the other side now I place it 00:30:37.720 --> 00:30:41.080 here and now we it's time to weigh it so 00:30:41.080 --> 00:30:44.200 what are you aiming for we usually are 00:30:44.200 --> 00:30:47.760 around 1% maybe a bit less to claim that 00:30:47.760 --> 00:30:50.960 it's a dry rope when you do this 00:30:50.960 --> 00:30:54.399 test she's good at this what she's 00:30:54.399 --> 00:30:56.480 really good at this are we ready to go 00:30:56.480 --> 00:30:58.440 to the weekend 00:30:58.440 --> 00:31:00.240 are we ready to go to the weekend we're 00:31:00.240 --> 00:31:04.320 talking about the dry limits sorry so 00:31:04.320 --> 00:31:07.639 yeah usually to declare that your 00:31:07.639 --> 00:31:10.320 water now while digging through all the 00:31:10.320 --> 00:31:12.679 different manufacturer websites I found 00:31:12.679 --> 00:31:15.039 out that there are a lot of different 00:31:15.039 --> 00:31:18.399 dry treatments with different labels 00:31:18.399 --> 00:31:20.440 sometimes the treatments are added only 00:31:20.440 --> 00:31:23.080 to the Shi sometimes both the sheath and 00:31:23.080 --> 00:31:25.240 the cor and sometimes they are better 00:31:25.240 --> 00:31:29.000 for our planet and labeled as PF F C3 00:31:29.000 --> 00:31:31.159 but just because the Rope is treated 00:31:31.159 --> 00:31:33.840 with something it doesn't mean that it's 00:31:33.840 --> 00:31:37.919 past UIA water repellent test to have 00:31:37.919 --> 00:31:41.159 UIA water repellent label the Rope needs 00:31:41.159 --> 00:31:44.720 to absorb less than 5% of water and if 00:31:44.720 --> 00:31:46.679 you want to learn more about what 00:31:46.679 --> 00:31:48.720 happens when the water penetrates the 00:31:48.720 --> 00:31:51.519 Rope I have made a video showing exactly 00:31:51.519 --> 00:31:55.960 that both in theory and in 00:31:56.080 --> 00:31:59.120 experiments [ __ ] there's the lad coming 00:31:59.120 --> 00:32:02.360 out and as a side note dry treatment not 00:32:02.360 --> 00:32:05.240 only blocks the water from entering but 00:32:05.240 --> 00:32:08.760 also the dust which can greatly increase 00:32:08.760 --> 00:32:11.279 the lifespan of the Rope we also tried 00:32:11.279 --> 00:32:14.120 washing the rope and see if that helps 00:32:14.120 --> 00:32:16.840 so yeah that's another Shameless plug of 00:32:16.840 --> 00:32:19.960 my previous videos what the 00:32:19.960 --> 00:32:23.760 hell yeah she's using the 00:32:23.760 --> 00:32:27.240 heels hi Mobility people hi Mobility you 00:32:27.240 --> 00:32:30.679 have shorter legs hey no no leg short 00:32:30.679 --> 00:32:32.880 leg 00:32:33.559 --> 00:32:36.240 shaving
