What shreds a climbing rope first? 

We found a Ropeman1 with ribbed teeth. It broke the dynamic rope at 4.95kN, less than the micro traxion. instagram.com/p/CoObDl9pntX/. Our quickies usually end up here on the Clips subchannel FYI www.youtube.com/@hownot2clips. Check out our new store! hownot2.store/

Imo a purposeful quickie adds to your effectiveness. Seeing that Grigri was very interesting. Bravo.

Would love to see how the Petzl ASAP fall arrestor stacks up as far as desheathing and catching a shock load.

Love seeing sketchy Andy in videos. His mom, Lynn was my art teacher and play director in middle school! So cool seeing him still in one piece.

Really nice videos! Appriciate it, especially the arborist ones. Cheers from a hungarian arborist from Switzerland!

Hell yeah Ryan! Bring in the Arborist vids lol.

Would be super curious about the petzl Tibloc

Thanks for all you do for the community!

Literally my favorite YT notification to get.. You probably have one of the few channels I'll watch no watter what comes on... Because if not entertaining, I'm learning something or both

Super excited for the next comparison!!!!

Hey man, congratulations on your new space! Looks grrrrrrreaat!!!!!! Keep it up!!!!

It would be nice to see how those devices are doing in icy conditions. I have CT rollnlock without sharp spikes (like the Gibbs in this video) because it meant to do well with ice on the rope.

Definitely like the quick format follow up!

This is such a good video for all the people that argue about rope solo devices!

Gibbs! Good stuff. I used them for years to prussic out of vertical caves. Used one in Alps to follow fixed ropes..never iced up. Great new lab!

Actual reliable data. Thank you!

Thank you for taking up our suggestions!!

Mix of short and long-form videos is my preference. Good stuff!!

I'm your big fan. I can't wait to see the next test video.

Great work! Thanks and love the content 😊

That Gibbs looks like a lanyard adjustor

Love the new lab! Beautiful😁

This is random and you’ve probably already tested it, but I’d be interested in seeing what a Connecticut tree hitch breaks/slips at. Also a surgeons knot with dyneema around a tree would be sick. Keep up the good work, your videos are awesome!!

That Gibbs is mostly seen in the industrial / rescue sector. Gibbs has models for cable ascension as on fixed ladders . I personally own several for rope and for cable . I like the gibbs units . Great video Guys !!!!!!!!!!!!

Great video! I have a Microtrax and Ropeman 2 for a solo TR setup.

Ryan, what about the Climbing Technology Roll'n'Lock? It has a very different cam/ridges than the Microtraxion, and seems a very good choice as a progress capture device, maybe you could test it out in this scenario as well? I know a few people who use it for rope soloing

The quick hits are great. I love the deep dives but sometimes don't have time, so, if it's just the nub of whatever issue, that's a plus, IMO

My palms get sweaty just hearing you guys talk about falling while climbing 😂

I use a TAZ Lov2 for rope soloing in addition to my microtraxion. Operates similar to a grigri. Would love to see a break test on that one

Please test the Petzl Shunt. Its completely toothless and i have seen it used for rope solo.

The gri gri was quite good! Even at that good failure number, it still holds and only slowly slips. Not gonna lie, glad I used the grigri for so long.

I know someone who took a factor 2 directly on to his partner’s Grigri with a brand new rope and it did indeed rip the sheath. .2 cam blew during the fall. Yes he should have backed up the first piece.

Thanks again for doing arborist tools!

Thanks for your sharing

I remember an old video, done in England if I recall, that tested industrial fall arrest devices in a drop tower. They all failed, and then they tested an old style Rescucender, and it was the only one to pass, but it is not a fall arrest device! a distinct problem with the Rescucender is dirty rope. Once the cam starts to wear, that nice radius on the rope contact undulations becomes a sharp edge. Good news, bad news: its very easy to inspect, but its a judgement call for when to replace. Other bad news, Petzel bought the design from Rock Exotica, the original maker. Petzl has come up with a replacement with captive mechanics, but an inferior rope path. Petzl did not relinquish the rights to the old design, so Rock Exotica can not make them under their own name.

Ryan, I have been binge watching your videos and they have encouraged me to get back into climbing so much so my girlfriend wants to learn with me. Great and very useful content. Thank you.

Oooh can't wait for the diverter carabiner tests!

You should definitely add the clips channel to your "Channels" tab on the main one!

I had the wear plate on my Croll get to a point where it was starting to create a sharp edge. The rope and teeth were more or less fine.

I like to see a porta wraps (bollards) and different ways of attaching to them tested. And if there is any loss of rope strength.

Its been shown that non-toothed ascenders like the Gibbs ascender will strip the rope at 5kN as well. This has been well established in tests. So the more aggressive toothed devices are not much different.

I second a lot of others that you should definitely test the Taz Lov 2 or 3. I think it's considered the gold standard in TRS these days, and it's what ive started using (with an extended microtrax as backup)

+1 for Edelrid Spoc. Cheers!

Yes for quicker videos! 😀

Would love to see testing on the taz lov2 and or 3. I have been using this for top rope solo and for roof work for several years as it’s an all in one device . Really want to know it’s behaviour at its limits and where those limits are .

You could try a unicore rope if you're looking for suggestions, the sheath won't come off.

Would be curious about some tests with the old micro traxion... on a 6mm rad line too!

I’d love to see the Edelrid Spoc and the tibloc up against the microtraxion in a similar test

Hey Guys there’s a CE Standard 353-2 and if the device is stamped it has passed a Factor 1 or 2 (sorry I cant remember without looking it up) with a 100kg load and is suitable for industrial back up device and suitable for 2 people in a rescue scenario

Love it, as always. Off topic, but would you guys be up for a hardware store chain episode?

Would love to see a test on the Soloist. If you can get your hands on one. No, you can't have mine.

Once I abseiled from a large concrete road bridge at night using head torches with my friend. I went first. Half way down I started swinging around on the rope. My friend followed me and we ran away from the scene. It wasn't until we got home I inspected the rope and it was 2/3rds shredded through from my swinging attempts. My friend had abseiled a 300ft bridge on a thread. I never told him a thing.

How about adding a wild country revo into that list of devices to test!

Yes yes yes do the carabiner around a tree branch I’m so excited

Is that Gibbs ascender not the 12mm + version? I think it is and if so, that is likely why it did so well on a smaller diameter rope than it’s designed.

curious about the "CT roll n lock", which has ridges, but a bit sharper than the gibbs

0:41 Roman test 0:48 Roman result 6.12 kN 0:50 Similar to Jumar Test 0:57 Jumar result 7.15 kN 0:59 Micro traction test 1:08 Micro trac result 7.15 kN 1:27 Gibbs test 1:35 Gibbs result 11.73 kN 1:40 GriGri test 1:50 GriGri result 8.78 kN

there is a small chance that i have made or touched that rope he is using! It was a cool manufacturing process.

another question. i dont know if you can get those in the US but edelrid makes some ropes with sheaths partly made out of aramid would be so interesting to see if those perform better than other ropes

Try a portawrap as an anchor to test ropes at full strength (no knots).

I have never been rock climbing. I have zero interest in ever doing it but I watched this whole damn video for some reason lol.

Is there somewhere a test on Beal Unicore ropes vs normal dynamic rope? Would seem like this is where one would shine. Or break instead of desheating.

Love the more condensed format. A little more banter would be ok though. I think ~10min video would be perfect

Is there a difference to how force impacts a rope when achieved dynamically (taking a TR solo fall with slack out) vs slowly/gradually (as in your tests)?

I was looking around for a foot en knee ascender (arborist use)en do not love the idea/device's with te teeth just for the reason they going to be obvios hard on the rope. I find the NOTCH EQUIPMENT : NOTCH JET STEP FOOT ASCENDER and this one has cams instead of teeth. of course the question is how this device performs with its cams and the rest of its construction form. (in arborist use these are normally not going to take a fall (and the generated forces of a fall) on theme...) they are just to ascend you as a person and the material on you. (your body is protected against falling by another device). thanks for your many test and experiment work, learned a lot and sometimes go back to look at certain things again. Greetings David

I'd love to see a tibloc tested against some of these jammers

I've got a rollnlock. It has grooves rather than teeth. I've just retired it when I discovered it won't bite on a weighted rope. Do you want it for testing?

As and arborist I have been using a gibbs 4sb rope grab on a 3/4 inch bull line to pull over trees. After putting 3 guys on a 25:1 I started thinking about the breaking or slipping point?. I know an eye to eye will fail at this point. Please help!!!

How about the Petzl croll ? It is often used as a toprope solo device

I wonder if the results would be different on ropes with permanent core + seath bond like the tendon tefix technology

Grigri in the vertical, cache loop creates enough weight in the brake strand to prevent slipping is my understanding.

Could you do a test on shock absorbers? I hear people say different things and didnt find answers in the manual myself.. when does the sewing in the shock absorber start tearing is my question... Via Ferrata slings are in the range of 40-120 kg, some tell me it starts to rip open on 120 kg, than ill assume the absorbica wich goes to 180 and 240 starts to rip open on respective loads!? I might be able to get hold on some old tearing slings wich i think is rated 50-120kg to send over

Please test the climbing technology rollnlock

Kong Duck please test!

Can you also test twin 6mm prusiks?

the grandwall progress capture device would be cool to see tested. No teeth, just one point

Can you get a projector pointing down to display the graph in real-time?

thank you fo video.i like your hairstyle

Have you ever done a "stored in a closet" video measuring strength retention of unused equipment not exposed to sunlight? Or does equipment kept for emergency use need to be replaced even if unused?

have you ever tested a soloist? I just picked one up and am curious about its strength.

The one that slowly slipped seems like the best bet, since you would just be slowly slipping down and could grab the wall with something

What about devices without teeth or ridges? Like the petzl shunt or grandwall uascend?

Add the clips channel to your "channels" section on youtube

If you are still taking device recommendations perhaps the dmm buddy 100 too

Curious about the Notch Jet Step.

Wondering how much that one time max stress relates to continuous lighter wear in terms of wearing out the rope.

Obviously there are PLENTY of uses for old rope buuuttt... Does anyone have any good ideas on where I might get my hands on retired rope? I'd like to use it for a crochet project!

New studio is looking wicked! Nice work.

Is the failure mode here the rope sheath itself failing? If this thing is gripping the sheath not the core (unlike a knot which involves the whole rope) then maybe it's just that the sheath is doing all the work?

Would be interesting to see a petzl shunt tested as it doesn't have teeth.

Is is possible that the microtraxion would brake before shredding the rope?

Link the new channel in the "Channels" tab on RU-vid, please!

Would it make a difference having a ohm in the system ?

Hi HowNOT2! Is there a way to calculate the force generated by a falling climber onto their gear? I wish to get over my gear fear and knowing approx how much I generated would perhaps help me.

Did they end up testing the Camp Lift?

If you haven't gotten a Harken Ninja, I would donate one for testing.

Could you add a Trango Cinch to the list? It’s more than likely going to slip.

at 4:20 he talks about testing a "diverter" with a rope and carabiner sinched. Has anyone seen this video? I can't find it.

All the devices (except the Gibbs) pull directly on the sheath and it breaks at around 5 kN, leaving the core intact. I guess you'd get a much higher result if you used a Unicore rope.

Seen the Instagram Wild country test, thank you for that, I thought it would be less likely to shred a rope. Lol it's not😂🤣
