The bulldozer is rated at 21kN, for those who were wondering

So many experienced climbers died because of the missing end knot... It's a shame... Good Grigri Hack 👍

'Puts stick on ground' Kid: I don't think so, mate (read in james Acaster voice)

As a new climber, 4-5 months, I really appreciate the content you’re putting out. I’m still learning how to make a PB&J, so thanks for the info!

Should've named the video: "The grim reaper hates this one easy grigri trick" ...but then maybe your weird cousin would be back and KZfaq wouldn't approve 😅

Keep up the good quality content! I started watching your channel ~2 months ago and can't get enough, your videos are so underrated. :)

I recently bought a Grigri 2 and been playing around with it a little bit. Thanks for the input. Very good knowledge to have . Thank you

And another life saving tip. Thank you soo much Joshua much appreciated.

Wow. Thank you, Josh. I had no idea that would happen. Then again, I've only been bouldering, but would like to expand.

Great info. I haven't seen it demonstrated like that before. Yeah I wanna see some exploration of the quarry!

Experienced or not that was a great piece of advice for all climbers! Thanks for thesecrethintthatshouldn'tbesecretatall

Theres also a big issue with being too close to a low anchor, in a top belay situation. If you contact the anchor when the climber falls the grigri can flip upside down and it completely unloads. If your hand isnt on the break linr then the climber that just fell pulling you into the anchor is now free falling even further. Its happened to me on both ends. luckily both times, hands were on the brake line and it only ended up in a panicked 5 ft drop.

Good shout, definitely something I'd not thought about.

This lil dude is the only KZfaqr, I would climb with. Very knowledgeable, hard working, and funny as hell.

I’ve actually never heard of this, good job thank you for the info!

Don't own a Grigri but I love your vids. Glad brands are sending you free stuff!

Great vid👌🏻😊 Im glad I found your YT channel. Greetings from Slovakia🇸🇰 stay safe🤜🏻🤛🏻

Thank you, man 👍 this information saves lives

I think I've experienced this without realizing what happened, thankfully it wasn't a scary situation...thx for enlightening me, cheers.

Thnx! Beeb thinking about switching to a grigri but have never heard anyone say that. Again, thnx

Thanks! I was just telling someone not to let go with the brake hand and I couldn’t explain why

This taught me something new!! Maybe saved me for future repels so thanks!!!

As someone looking to switch from ATC to assisted breaking device all this stuff is really helpful, thanks!

Your kid giving you the water was so cute!!

Yep, definitely my favourite underground, on the ground climbing channel. Hahaha.

aweseome video, please do some more videos like this!

I don’t use the gri gri but if I ever have to it nice to know this lil bit of info! Bravo beta

I just bought my first rope this week. This was very helpful in understanding some of the physics of loaded rope. Very useful. Thanks JP

I use an ATC but the rope handling tips changed my life 😂

Awesome i have that same exact rope. Crag we care classic. Love it.

Muchas gracias por tomarte el trabajo de hacer esta prueba en campo. Saludos!

Wholly cow.....thanks! I never thought that out.

Great info right there dude!

Very useful . Thank you 🙏

Good information. Yes, some quarry climbing pls. 👍

I would love to see some quarry video! Awesome demonstration video, too!

Very good to know. Thanks a million.

Haven't climbed yet but have been really wanting to get involved. This is such an important point to make and something I never would have thought us. Thank you for making this.

Could you do a video on anchor placement for top rope or rappelling??

Using both the Sender harness and a We Care 80m. Been a tremendous fan of both, though will say would’ve appreciated the front loops were not coated but the same low profile nylon as the back, as well as only Edelrids are properly lap coiled, but Mammut is the best of everyone else.

Nice info, and good to know AND this is why the Grigri is not a hands-free device!

Especially when you explain stretch on dynamic rope!

Yes on a Quarry vid! And where's your video on your Dad's route? Informative and entertaining content as usual. And I was one of those nubs that tried to uncoil their first rope from the floor, most frustrating 30minutes of my life. :)

Great video! mammut is pissed that you use their free gear to test out a petzl device! 😂

That harness is dope lol. I love gear in obnoxious colors

Nice, thanks alot !!!

Dayum! I think in science class, we called that one "Potential energy"!!! Springy action on the dynamic ropes hey?

I have that very same rope. Mammut Classic 9.9 80M We call it the "Long Running Bastard." Heavy as hell, management nightmare at an upper belay station BUT you will NEVER run out of rope on any pitch. Rappelling on a Big 8, that rope feels like it goes from 9.9MM to an 8 real quick towards the end!

Long rappels, Petzl recommends using an extra, small sized, braking biner, or attaching the grigri with one that has the brake built in like the Petzl Freino (personally, I've never seen braking biners used except underground/caving)

@6:17 for the content you came here for

Hmmm... Interesting. I would have never thought about that! Generally, I instruct by saying reason for the brake hand on a GriGri is just in case maybe the device fails or installing the rope was backwards, essentially turning it into an ATC.

Damn man! Almost 33k subscribers?!?! Congrats, you deserve it! That’s awesome to see because I’ve been here since you started (or close to it). I really appreciated how humble you are and that you kept videos up where you made a mistake… despite all the haters and keyboard warriors who’ve never climbed a day in their life; let alone tried to spread knowledge on KZfaq for strangers to grow. That kind of content is rare, which is sad because it helps amateurs learn so much. Lol I’m in no way implying that you make mistakes often btw 😂. I just know that most content creators would delete their videos if they fricken pronounced a word incorrectly or something petty like that. We’re all here to learn and share experiences…. And to watch your daughter steal your props hahahaha. Keep it up brother because you’re sharing valuable knowledge that could (or potentially has) save lives. Not much rock climbing out here in Detroit, MI but I’ve always enjoyed your content because I spend a lot of my free time in tree canopy’s (often using a grigri for RADS, if I’m feeling lazy and don’t wanna rope walk). Keep it up brother and stay safe 👍.

Thanks !!

I'm a newb with a gri gri, thanks for the tip!

It makes sense to me. But I had never thought about that. I don't think I have ever rappelled on a single strand dynamic rope, only static, or double rope. But I guess it could happen with double ropes as well with a brake like mega jul.

I would never rappel on a grigri type device, but never say never... Let's imagine I'm forced to, It would have surprised me for sure. I honestly did not know about that hazard, so it's a real thank you I guess. I usually never let go of the break side of the rope but here again, never say never, that's why it's called an accident after all. Great video as always.

Thanks for the lifesaver! 👍😁

the little one is keeping pops hydrated how cool nice they sent you some gear from Mammut

great stuff

Thank you❤

Legit info as always.

This also applies when you're belaying. It's easy to deck your climber if you have most of the rope out and your climber is near the ground. If you don't have your hand on the rope and you release the brake as we've all seen here, that rope whips through the grigri due to the stretch and before you know it your climber is on the deck. Every grigri accident I've heard of is on the belay and this shows one example of what can happen.

Gonna use this to test trad gear connected to me whilst hanging on a top belay lol

Nice!

Start watching at 6:00. Problem is when you're setting up an anchor on top of a rock climbing route, it takes sole serious math work to tie the end knot at the exact right spot.

My first rope was an 80 meter, and I completely butchered uncoiling it. Took me an hour and a half to get it all straightened out.

Thanks Josh. I appreciate this. I am new and assembling my gear for top rope soloing and just got a Gri Gri and I was wondering about this exact question - do you need to keep brake hand on. So it is really helpful to know this kind of stuff before I make mistakes that were knowable before hand. - and the end knot!!! Was watching free solo again the other day and Alex had his first fall and got all busted up because he fell and no end knot so girlfriend watches the end of the rope go right through the Gri Gri - and there is another scene where he and Tommy Caldwell and like two ft from the end of their rope repelling with a Gri Gri and have a super loose single figure 8 knot at the end that I am sure wouldn't hold. But that also made me think - hey they really trust this piece of equipment so it must be rock solid.

There are lots more things that contribute to extra distance for a leader fall. Slack in rope + stretch in rope + slack in belay + stretch in belay + slack in pro + stretch in pro - rope belayer can haul in. What you estimate is a 2m fall can easily become over 10m.

Solid anchor

Really cool demo cheers Josh! Defo wondered how you go about using 2 gri-gri's at the same time!

Does this happen to the grigri plus too? cuz it has a lever that disengages.

Love the dozer. So- less of an issue (/non-issue) if repelling on a static line? Thanks.

No helmet on the edge caterpillar tut tut you should no better than that 🤣 love from the 🏴󠁧󠁢󠁥󠁮󠁧󠁿

2 Grigri videos in a row!? Let's keep it going.

the rope stretches 30% under super heavy loads, as in it might hit ~20% with a heavy whipper. The real test you're doing at 8:00 is a static stretch, which will be much lower, around 10%

This is such an important video maybe you should trim the start a bit or add another few tips at the end if you want to achieve a certain length. Thanks for making this.

First lesson i learned, shout out to prusik knots.

Worthwhile backing up a grigri with prussic either above or below?

nice

I experienced this today, i never let go of the brake rope, but i did a 60m dynamic rope rappel and the rope was just trying to fly through my atc because of the elasticity. Luckily i had a third hand. Not to mention the atc felt like it was hot enough to melt my rope if i stood in one spot.

You should upload some videos of you climbing!

Mabye I got some things wrong at first place or a different approach to decending on rope but I have got some questions: Why are you decending on a single rope? How do you get your rope back? And adding a Prusik-knot or something similar at the unloaded rope solves the problem you are pointing out. In my opinion this should be standard anyways. Please correct me, if missed the point.

I am a cave climber. I use a semi static rope. So it still has some stretch. Once I rappelled down the full 50 meters of my rope. Got out of the rope at the bottom close to the end knot and siiiiing: looked at the rope dangling 3 meters over my head from the middle of the cave ceiling. (I survived, because we used two ropes this day and I stopped the other guy from untying his rope.)

Wouldn’t it act different with MORE weight on the line (holding the cam locked tighter)? It would have been cool to see it done with a 50m rope as that’s a length I’m likely to experience.

Whoa! Thanks for the heads up 👍

good to know..... i mean ill probably never leave my climbing gym, but....good to know

I would like to see video from the safari!

Tq info 🤙🧗‍♂️

Thank you for the, DON'T STEP ON THE ROPE. I have climbed with a few BOZOS that doesn’t think that matters.

What did you do to make the rope slip? It's not clear in the video.

Using a static rope that has very little elasticity would prevent that from happening, correct?

I dont rapell on grigris. I use em soley for lead belay, folowers get belayed by me with atc guide from the top and to rapell i use the atc aswell or the 8 if the atc is not available. Ive also never done long single rope rapells. Only one single one wich was like 12m to clean and check out a possible bolder /short route in my area. Wich i ended up first ascending on toprope since there is no cracks or anything and i didnt want to bolt virgin rock with questionable legality.

Great advice for this newbie but dang, it took over 8 minutes to get to the point 😂

👏👏👏

Doesn’t the grigri plus prevent you from completely opening the lever like in your example?

Reason #1237 to always knot the ends. But i'm not convinced about the springing action. Wouldn't rope stretch happen gradually over the length of the rappel, so at the end only the 10' tail would have stretch left? Does anyone have a link to a report or an anecdote where this springing action was the primary cause of the accident?

Always close the system. Always. Not sometimes... ALWAYS.

70 to 80 feet of stretch on a 70 meter/80 meter rope?

Keep your hands off my dozer!!!

Holy sh*t that was scary
