WEBVTT 00:00:00.160 --> 00:00:02.000 all right 00:00:02.000 --> 00:00:06.640 Neo or maybe how French would say new 00:00:06.640 --> 00:00:09.960 which is not a new gri petel is listing 00:00:09.960 --> 00:00:12.360 this as a completely new blay device so 00:00:12.360 --> 00:00:14.719 let's see why I had this for about 5 00:00:14.719 --> 00:00:17.240 months I did a bunch of 00:00:17.240 --> 00:00:19.640 climbing I did a bunch of 00:00:19.640 --> 00:00:23.359 testing and I have a bunch of mixed 00:00:23.359 --> 00:00:25.960 feelings about this 00:00:25.960 --> 00:00:29.199 meox so about a year ago I got an email 00:00:29.199 --> 00:00:32.000 from Sebastian petzel turns out that his 00:00:32.000 --> 00:00:34.440 grandpa developed the original idea of 00:00:34.440 --> 00:00:37.719 grigory so I felt very honored by such 00:00:37.719 --> 00:00:41.200 email and he offered me to test this and 00:00:41.200 --> 00:00:43.200 said that I can say whatever I want 00:00:43.200 --> 00:00:46.039 about it so this video is not sponsored 00:00:46.039 --> 00:00:48.760 by petel now what was funny when later I 00:00:48.760 --> 00:00:50.800 was exchanging details with someone from 00:00:50.800 --> 00:00:54.199 petel team and they said that it is safe 00:00:54.199 --> 00:00:57.000 even in the case of your strange 00:00:57.000 --> 00:00:59.320 experiments in case you haven't seen I 00:00:59.320 --> 00:01:01.640 have made a video explaining the physics 00:01:01.640 --> 00:01:05.280 of how gri works and I showed a bunch of 00:01:05.280 --> 00:01:09.119 ways how it would not 00:01:09.320 --> 00:01:14.280 work oh [ __ ] so let's do some of those 00:01:14.280 --> 00:01:17.799 strange experiments and compare grigory 00:01:17.799 --> 00:01:23.079 with neox while grigory weighs 175 G 00:01:23.079 --> 00:01:26.960 neox broke my scale because my scale 00:01:26.960 --> 00:01:31.040 doesn't like blay devices above 200 G 00:01:31.040 --> 00:01:34.439 but Jokes Aside it's 60 G heavier and if 00:01:34.439 --> 00:01:36.240 you would hold them side by side you 00:01:36.240 --> 00:01:39.320 would feel a difference however this 00:01:39.320 --> 00:01:41.720 extra weight did not seem to bother me 00:01:41.720 --> 00:01:44.520 much while delaying now while grigory 00:01:44.520 --> 00:01:46.600 has a very simple mechanism where a 00:01:46.600 --> 00:01:49.360 bunch of frictional forces contribute to 00:01:49.360 --> 00:01:52.159 overcoming the tension in the spring and 00:01:52.159 --> 00:01:54.920 then the cam moves and pinches the Rope 00:01:54.920 --> 00:01:57.079 again I have explained everything in 00:01:57.079 --> 00:01:59.399 this video and it's very interesting and 00:01:59.399 --> 00:02:01.280 I highly recommend to see that because 00:02:01.280 --> 00:02:03.960 Neo actually kept all of that design you 00:02:03.960 --> 00:02:06.600 can see there is still same spring 00:02:06.600 --> 00:02:07.879 camming 00:02:07.879 --> 00:02:12.640 action but now we have a wheel which can 00:02:12.640 --> 00:02:16.680 spin but also it can move up and down 00:02:16.680 --> 00:02:19.800 and if it's in up position the wheel is 00:02:19.800 --> 00:02:22.599 blocked from spinning and at that point 00:02:22.599 --> 00:02:27.620 it acts essentially the same as grig 00:02:27.620 --> 00:02:33.200 [Music] 00:02:33.200 --> 00:02:36.280 so what does all of that mean in 00:02:36.280 --> 00:02:39.959 practice well let's start with the good 00:02:39.959 --> 00:02:42.959 the Rope does run really smoothly for 00:02:42.959 --> 00:02:45.560 the device it's actually very 00:02:45.560 --> 00:02:48.319 satisfying it's super 00:02:48.319 --> 00:02:50.640 smooth however notice that while I'm 00:02:50.640 --> 00:02:53.120 feeding slack I'm not touching the 00:02:53.120 --> 00:02:56.879 device and if this is how you like bling 00:02:56.879 --> 00:02:59.519 and maybe you are coming from tubular 00:02:59.519 --> 00:03:02.560 Style devices you can probably stop this 00:03:02.560 --> 00:03:04.799 video right here go buy this and you 00:03:04.799 --> 00:03:06.720 will be really 00:03:06.720 --> 00:03:10.239 satisfied thank you for 00:03:10.879 --> 00:03:13.720 watching now if you stayed let me 00:03:13.720 --> 00:03:16.680 present some of my speculations I think 00:03:16.680 --> 00:03:19.360 when petzel was developing the original 00:03:19.360 --> 00:03:22.840 grigory this smooth action was actually 00:03:22.840 --> 00:03:26.239 what we were trying to achieve 00:03:26.239 --> 00:03:28.799 however if you try to feed the slack 00:03:28.799 --> 00:03:30.760 like this with original grigory 00:03:30.760 --> 00:03:32.840 depending on your rope thickness and 00:03:32.840 --> 00:03:35.159 many other factors it's very likely that 00:03:35.159 --> 00:03:36.920 the grigory will simply lock and you 00:03:36.920 --> 00:03:39.720 will have some trouble but creative 00:03:39.720 --> 00:03:42.159 climbers came up with a solution is to 00:03:42.159 --> 00:03:44.920 press on the cam to disengage it and 00:03:44.920 --> 00:03:47.040 continue feeding slack like this which 00:03:47.040 --> 00:03:49.760 actually worked so well that if you 00:03:49.760 --> 00:03:53.000 would go to any at least Europe cracks 00:03:53.000 --> 00:03:55.200 you would see that majority of people is 00:03:55.200 --> 00:03:57.239 belaying like this right 00:03:57.239 --> 00:03:59.879 now and of course there is many wrong 00:03:59.879 --> 00:04:02.280 ways how to do this and I showed a bunch 00:04:02.280 --> 00:04:04.920 of wrong ways in the same video however 00:04:04.920 --> 00:04:07.480 if you keep the rope in your brck hand 00:04:07.480 --> 00:04:09.720 even if you're pressing on the cam and 00:04:09.720 --> 00:04:12.000 the climber would fall at that moment 00:04:12.000 --> 00:04:14.720 the grigory is most likely to lock and 00:04:14.720 --> 00:04:16.400 actually if you check the manual of 00:04:16.400 --> 00:04:19.079 grigory you will find this listed as an 00:04:19.079 --> 00:04:22.160 option of giving slack fast but guess 00:04:22.160 --> 00:04:24.919 what if you check the manual of neox 00:04:24.919 --> 00:04:28.479 there is only one way to give slack now 00:04:28.479 --> 00:04:30.120 so here are some more of of my 00:04:30.120 --> 00:04:32.320 speculations original grigory is 00:04:32.320 --> 00:04:34.520 actually designed so well that it's 00:04:34.520 --> 00:04:36.600 quite hard to make it fail and that's 00:04:36.600 --> 00:04:38.960 why it became so popular and that's why 00:04:38.960 --> 00:04:41.560 so many of bad ways of using it became 00:04:41.560 --> 00:04:43.639 very popular and that's why we still 00:04:43.639 --> 00:04:46.160 have accidents with 00:04:46.160 --> 00:04:49.919 it unfortunately so this all brought a 00:04:49.919 --> 00:04:52.400 lot of bad rep for the grigory which is 00:04:52.400 --> 00:04:55.240 kind of strange when one of the safest 00:04:55.240 --> 00:04:58.199 devices is the most criticized probably 00:04:58.199 --> 00:05:00.960 devices and this is what I think petel 00:05:00.960 --> 00:05:04.479 tried to fix by hinting that you know 00:05:04.479 --> 00:05:07.360 what do not touch the device however 00:05:07.360 --> 00:05:11.039 giving slack like this became so popular 00:05:11.039 --> 00:05:13.440 not only because this other method 00:05:13.440 --> 00:05:14.880 wasn't always 00:05:14.880 --> 00:05:17.440 reliable giving slack like this is 00:05:17.440 --> 00:05:19.720 actually more comfortable and bling like 00:05:19.720 --> 00:05:21.680 this is more comfortable and here are a 00:05:21.680 --> 00:05:23.919 couple of reasons I can always give as 00:05:23.919 --> 00:05:26.360 much slack as I want and my blade device 00:05:26.360 --> 00:05:28.800 is not falling down while I'm doing that 00:05:28.800 --> 00:05:30.919 and I'm in the comfortable position now 00:05:30.919 --> 00:05:33.039 with Neo you can actually give slack 00:05:33.039 --> 00:05:35.800 quite fast but the delay device will be 00:05:35.800 --> 00:05:38.639 bouncing all over the place however 00:05:38.639 --> 00:05:42.039 there is another issue if I give slack 00:05:42.039 --> 00:05:43.840 and I prepare to give more slack and now 00:05:43.840 --> 00:05:45.880 I need to take well guess what first I 00:05:45.880 --> 00:05:47.960 need to bring my Brak hand closer to the 00:05:47.960 --> 00:05:50.479 device before I can take so I need to do 00:05:50.479 --> 00:05:53.240 some arm juggling and only then I can 00:05:53.240 --> 00:05:56.199 take with the other method if I'm giving 00:05:56.199 --> 00:05:58.400 slack and suddenly I need to take well I 00:05:58.400 --> 00:06:01.680 just take that's much more practical so 00:06:01.680 --> 00:06:04.560 can you belay like this with Neo well 00:06:04.560 --> 00:06:06.599 the manual doesn't say anything about 00:06:06.599 --> 00:06:09.120 this I tried asking petel and I still 00:06:09.120 --> 00:06:11.680 haven't received reply to my emails so 00:06:11.680 --> 00:06:14.199 if I will do I will add a pinned comment 00:06:14.199 --> 00:06:18.120 now in practice it does work but check 00:06:18.120 --> 00:06:22.280 this out or listen this 00:06:23.880 --> 00:06:27.120 out so yeah it makes a ratcheting sound 00:06:27.120 --> 00:06:29.599 when you try to pull the Rope fast and 00:06:29.599 --> 00:06:31.120 and I gave this device to my friends to 00:06:31.120 --> 00:06:33.560 try they were like is this broken so I 00:06:33.560 --> 00:06:35.880 think it's not broken however it's very 00:06:35.880 --> 00:06:38.440 noticeable and if you are in very quiet 00:06:38.440 --> 00:06:41.479 crack and somebody does I can only 00:06:41.479 --> 00:06:43.479 imagine when this will become even more 00:06:43.479 --> 00:06:45.080 popular and this is going to happen in 00:06:45.080 --> 00:06:47.240 the 00:06:51.160 --> 00:06:53.720 cracks okay let's say you don't care 00:06:53.720 --> 00:06:57.000 about Tranquility at the cracks people 00:06:57.000 --> 00:07:00.240 shout there anyway blast music dogs that 00:07:00.240 --> 00:07:03.400 are barking so a bit of is no problem 00:07:03.400 --> 00:07:06.520 for you and the only thing you care is 00:07:06.520 --> 00:07:09.479 is it safe so same as grig if you press 00:07:09.479 --> 00:07:12.319 on the cam but do not hold the Rope your 00:07:12.319 --> 00:07:15.720 climber is going to un alive and since 00:07:15.720 --> 00:07:18.960 the Rope runs smoother through Neo he or 00:07:18.960 --> 00:07:22.560 she will unal life faster 00:07:22.560 --> 00:07:26.000 so hold the Rope now what about a 00:07:26.000 --> 00:07:29.000 completely No Hands situation first 00:07:29.000 --> 00:07:31.879 let's start with a gri which as you can 00:07:31.879 --> 00:07:35.360 see can definitely 00:07:36.479 --> 00:07:40.639 slip but now let's switch to 00:07:42.280 --> 00:07:44.000 Neo 00:07:44.000 --> 00:07:48.360 whoa it falls uh 00:07:50.560 --> 00:07:53.720 faster it actually falls faster it falls 00:07:53.720 --> 00:07:56.639 smoother smooth death yeah you can have 00:07:56.639 --> 00:07:57.800 a smooth 00:07:57.800 --> 00:08:01.680 death with kind of wants to lock it 00:08:01.680 --> 00:08:04.840 goes but it's not enough for it to lock 00:08:04.840 --> 00:08:08.560 yeah seems like the gri is more grabby 00:08:08.560 --> 00:08:12.120 and more likely to stop the fall in case 00:08:12.120 --> 00:08:15.080 of no hand situation so it looks like a 00:08:15.080 --> 00:08:17.960 slight downgrade compared to the grigory 00:08:17.960 --> 00:08:21.440 in terms of safety and they said I won't 00:08:21.440 --> 00:08:25.479 be able to make it fail with my strange 00:08:25.479 --> 00:08:27.720 experiments but let's switch the gears a 00:08:27.720 --> 00:08:30.000 little bit and let's talk about taking 00:08:30.000 --> 00:08:32.440 the slack since the Rope runs much 00:08:32.440 --> 00:08:35.120 smoother through the device my initial 00:08:35.120 --> 00:08:37.320 thought was that it's going to be much 00:08:37.320 --> 00:08:40.519 easier to take the slack for the last 5 00:08:40.519 --> 00:08:42.640 months when I went climbing I kept 00:08:42.640 --> 00:08:46.120 alternating between neox and gri and I 00:08:46.120 --> 00:08:49.000 couldn't understand if it's easier to 00:08:49.000 --> 00:08:52.360 help the climber with the new device or 00:08:52.360 --> 00:08:55.800 not so let's do some more of my strange 00:08:55.800 --> 00:08:58.720 experiments as they say first I tried 00:08:58.720 --> 00:09:01.440 simple jump 00:09:03.440 --> 00:09:06.600 taking but it was very hard to feel the 00:09:06.600 --> 00:09:10.360 difference except that Neo was 00:09:10.360 --> 00:09:13.240 clicking so then I built this setup 00:09:13.240 --> 00:09:15.399 where I could compare the force needed 00:09:15.399 --> 00:09:18.399 to lift up my weights essentially 00:09:18.399 --> 00:09:20.760 comparing the friction inside the blade 00:09:20.760 --> 00:09:25.040 device yeah so it's moving up at 00:09:27.320 --> 00:09:32.320 0.65 0 64 so let's try the same with the 00:09:32.320 --> 00:09:34.600 old 00:09:41.600 --> 00:09:45.480 gri for some reason it feels harder but 00:09:45.480 --> 00:09:48.600 it's reading the same 00:09:48.600 --> 00:09:51.600 63 00:09:54.200 --> 00:09:56.760 interesting 00:09:56.760 --> 00:09:59.519 65 same 00:09:59.519 --> 00:10:03.560 feel the same so I tried with 60 kog and 00:10:03.560 --> 00:10:05.480 I couldn't feel the difference I tried 00:10:05.480 --> 00:10:08.800 with 40 kilog and where still was no 00:10:08.800 --> 00:10:12.160 difference which left me so confused 00:10:12.160 --> 00:10:14.640 that I probably tried a thousand of 00:10:14.640 --> 00:10:16.959 times to measure it again and again and 00:10:16.959 --> 00:10:20.600 again until I just stopped the camera 00:10:20.600 --> 00:10:23.800 and I noticed something which now 00:10:23.800 --> 00:10:26.760 absolutely makes sense remember when I 00:10:26.760 --> 00:10:29.600 said that the wheel can go up and and 00:10:29.600 --> 00:10:33.320 once it's in up position it's locked and 00:10:33.320 --> 00:10:38.040 then it acts the same as grigri well 00:10:38.040 --> 00:10:42.040 duh it only spins while it's under 00:10:42.040 --> 00:10:44.480 certain load so it's 00:10:44.480 --> 00:10:47.160 easier but if you load it more then it 00:10:47.160 --> 00:10:49.760 locks and then it's the same so this is 00:10:49.760 --> 00:10:50.800 30 00:10:50.800 --> 00:10:53.399 kg the wheel 00:10:53.399 --> 00:10:56.360 spins and then it locks and now the 00:10:56.360 --> 00:11:00.440 wheel is not spinning anymore 00:11:03.639 --> 00:11:05.399 so now I want to figure out what's the 00:11:05.399 --> 00:11:07.560 load needed for the wheel to stop 00:11:07.560 --> 00:11:13.519 spinning and stop helping let's try 20 00:11:19.600 --> 00:11:22.720 kg okay so now it's doing this weird 00:11:22.720 --> 00:11:26.680 clicky clacky thing so that pretty much 00:11:26.680 --> 00:11:29.399 explains why 00:11:29.399 --> 00:11:31.639 this 00:11:31.920 --> 00:11:34.839 happens let's see at what weight it 00:11:34.839 --> 00:11:40.839 would just spin freely and be nice so at 00:11:47.240 --> 00:11:50.880 15 and it goes easy to pull hard easy 00:11:50.880 --> 00:11:54.360 hard easy hard easy hard it's 00:11:55.639 --> 00:12:01.000 like okay this is only 5 kilos 00:12:03.639 --> 00:12:06.279 it's still 00:12:07.760 --> 00:12:12.040 clicking but less so it seems like above 00:12:12.040 --> 00:12:15.800 20 kilos it's permanently locked below 00:12:15.800 --> 00:12:18.680 20 kilos it's clicking clack clack clack 00:12:18.680 --> 00:12:21.920 clack cl cl clck and only on very very 00:12:21.920 --> 00:12:24.320 very minimal loads it's running very 00:12:24.320 --> 00:12:26.360 smoothly 00:12:26.360 --> 00:12:30.199 so disappointing I wanted always to run 00:12:30.199 --> 00:12:32.320 smoothly and then catch fast that would 00:12:32.320 --> 00:12:35.079 be ideal 00:12:37.720 --> 00:12:41.800 device cl cl so yeah it is easier to run 00:12:41.800 --> 00:12:44.920 the Rope through the device without load 00:12:44.920 --> 00:12:47.360 but as soon as the load is applied which 00:12:47.360 --> 00:12:49.680 is when you're helping your climber it 00:12:49.680 --> 00:12:51.959 will start clicky clacky and then at 00:12:51.959 --> 00:12:53.600 some point there is no difference 00:12:53.600 --> 00:12:56.279 anymore so kind of an 00:12:56.279 --> 00:13:01.000 improvement but could be better 00:13:01.000 --> 00:13:04.240 oh and also another thing when I'm going 00:13:04.240 --> 00:13:07.560 down sometimes the wheel needs to click 00:13:07.560 --> 00:13:10.160 back into certain position before it Smo 00:13:10.160 --> 00:13:11.680 again this is kind of annoying when 00:13:11.680 --> 00:13:14.360 you're belaying sometimes when you want 00:13:14.360 --> 00:13:16.519 to lower the climber just a little bit 00:13:16.519 --> 00:13:18.720 there is this little jerk of like click 00:13:18.720 --> 00:13:20.800 and then it's smooth for the rest of the 00:13:20.800 --> 00:13:25.440 time let me show you this again 00:13:35.959 --> 00:13:38.560 so what's the big takeaway of all of 00:13:38.560 --> 00:13:41.320 this new invention I absolutely love how 00:13:41.320 --> 00:13:43.199 smooth the Rope runs through the device 00:13:43.199 --> 00:13:46.360 now don't get me wrong this is fantastic 00:13:46.360 --> 00:13:49.199 I'm impressed by this design and if you 00:13:49.199 --> 00:13:52.480 are delaying like this then as I already 00:13:52.480 --> 00:13:55.360 said this is a massive upgrade to you 00:13:55.360 --> 00:13:57.759 and you should definitely buy this you 00:13:57.759 --> 00:14:00.759 will be very happy oh otherwise I do 00:14:00.759 --> 00:14:02.759 understand the direction that petzel 00:14:02.759 --> 00:14:05.639 took however I think that this is a 00:14:05.639 --> 00:14:07.800 little bit of missed opportunity 00:14:07.800 --> 00:14:10.160 original Gregory was one of the safest 00:14:10.160 --> 00:14:12.560 devices on the market and if only 00:14:12.560 --> 00:14:15.360 instead of trying to Advocate as to keep 00:14:15.360 --> 00:14:18.160 the hands away from it they would have 00:14:18.160 --> 00:14:21.839 made it somehow always lock maybe 00:14:21.839 --> 00:14:24.040 similar to Revo if the Rope is running 00:14:24.040 --> 00:14:26.759 at certain speed maybe it would lock 00:14:26.759 --> 00:14:29.560 that would be amazing and no clicky 00:14:29.560 --> 00:14:30.759 sounds 00:14:30.759 --> 00:14:33.320 please and maybe improve a little bit 00:14:33.320 --> 00:14:36.480 ergonomic how you are holding the device 00:14:36.480 --> 00:14:38.920 and that would be the perfect bling 00:14:38.920 --> 00:14:43.160 device for me personally all right now 00:14:43.160 --> 00:14:45.279 the best part for me of making these 00:14:45.279 --> 00:14:48.800 nerdy videos is the geeky nerdy people 00:14:48.800 --> 00:14:51.480 who leave comments on my stuff I 00:14:51.480 -->
