Climbing nuts tested to destruction in real rock. Watch us do our first tests of passive climbing protection in some bomber granite. We tested a Black Diamond Micro Stopper, some BD stoppers and an older Wild country nut. Let us know if you want to see more tests of passive climbing protection. Check out this video where we broke nut...

We think we are funny by bringing a BBQ and watermelon and a whole bunch of food up El Capitan that we didn't need. We also do give helpful tips marked by the youtube chapters. Think of things that will last, have variety, plan for easy meals (cooking and cleaning up). It was rad meeting Brittany Goris (2021-08-18 13:42:02 +0000 UTC View Post
---------I debated charging Patrons for this type of episode. It took a bit of work but is experimental and doesn't fall into our break test or fancy project category. I appreciate your donations to this channel and don't want to abuse the per episode "charge for this post" button.------
MBS or minimum breaking strength is great for comparing one product to another and I appreciate having standards on life supporting gear, BUT to boil down a piece of gear to only 1 single number doesn’t tell the whole story and we discuss gear, their ratings and value and limits of backyard science.
MBS is Minimum Brea...

Brent Roth gave me a maillon rapide aluminum quicklink rated for 25kn MBS that could make missions easier if weight matters. These are 3x lighter than steel at 48grams vs 137grams. It broke WAY higher than MBS at 53kn and the steel maillon rapide broke at 65kn. Why not use these if they are so strong???

CAMP Tricams are either active or passive protection while rock climbing. We test them in both uses in real rock and we found the noses would bust off since that is a lot of force focused on one single point. We did another episode in our lab at https://youtu.be/k...

I thought Petzl GriGri's would break the ropes if pulled hard enough but they slipped, even the 11mm rope. These were slow pull tests and I'm curious what will happen in future drop tower test of the same thing. We also tested a Beal Birdie which feels like a hardy steel body but I wasn't that fond of using it when it because it went...

If a span is 180 degrees it has infinite force on it. Even zipline and electric wires have sag in them. So 170 degrees is 5x the force as what is applied in the middle. I thought an American Death Triangle put magical amounts of forces on the bolts and anchor material since the top line is 180 degrees. Come to find out it...

Hey Brazil, we test 6 Grampo P bolts. Robelois donated them and Rodrigo Moota told us the welds are unreliable and the carabiners could unclip but they are everywhere in Brazil so lets find out how strong they are. They are installed backwards because the force should not really be applied to the unreliable weld. Buy better bolts if ...

I triloaded carabiners at the steepest angle i could and... you guessed it... it reduced the strength. Albeit higher than I originally thought. I believe it's proper term is called biaxial loading but we all throw "triloading" around so often that I am using it here. Check out 2021-06-23 13:38:08 +0000 UTC View Post

The rule supposedly is that you want a friction hitch to be 3mm smaller than the diameter of rope you are trying to grab and to use 3 wraps. We did a bunch of tests and here are the numbers:

Please don’t rope jump! But this is HOW if you don’t listen. I believe it’s better to share safety systems than to withhold it if people are going to do what they are going to do. If we glamorize it on a tv show, we can at least show what goes into it. Please don’t rope jump!
