I just put this together from closet gear after receiving a Tindeq as a gift a few weeks ago. Imo they are too long for standard Alpine draws. Those cam placements are surely jankier than the huge trees next to them. Whether thats your thing or not is totally personal preference but, I find them useful. Warm up is important. It takes a significant amount of time to develop the tendon and ligament strength that go hand in hand (lol) with grip strength and you will gain this development first and foremost through climbing. I could go on and on with details so if you have any more questions, please ask. the knot might snag. I don't know why people are feeding you a bunch of ridiculous information in this thread. Nope, it doesn't matter really at all. Doubt that a cheap quick link from Home Depot is. And yes I do remember being above the static anchor few times when setting up a top rope (I believe that's the most common case of climber being anchored with sling above the static anchor). The Tindeq allows you to measure maximum voluntary contraction at each given time, whereas with weight on a loading pin or sling you're limited to the MVC of the last second of the last rep. The weakest link is the protection(Cam, nut, whatever) you put into the wall. " Although the Pro version looks interesting in that they doubled the webbing material at the tether side where you girth hitch it to your harness. not a great idea. I thought I would need to add a board like the other pics i posted but nope, it works as is. The discussion over nylon vs. How should leg work be programmed with climbing and antagonist work? Right now I do climbing specific training (i. and shorter) are a tweener size that wouldn't be used often; some climbers use them for tying off pitons. Posted by u/drflex - 3 votes and 11 comments Usually around 16-20mm wide, nylon climbing slings are much bulkier (and more durable) than lightweight 6-14mm Dyneema slings. Glad to hear you’re off to a great start. Using it for alpine draws, slings, dogbones, etc is all good because it's not catching a static load, the rope is dynamic and therefore the sling doesn't have to take the same kind of force as it would catching a static load directly. The image of a sling straight vs doubled vs girth hitched and it's relative strengths float around and is taken as doctrine. I guess the possible benefits may be the simplicity of this setup and maybe more ease if the necessity to escape the belay arises. I absolutely abhor their training gear. I had to relearn a lot of technique. The video makes it seem like you are belaying someone with only a doubled up sling. Of course, then it becomes more important how close exactly you grip the band. rated strength is NOT even close to a direct measure of safety, since an anchor is a system and no single component should ever be subjected to the breaking strength of a cord. Safe working load is usually significantly lower, around 1/5th of the breaking strength. Top quality, great selection and expert advice you can trust. Sure, you don't need to worry about breaking strength with pretty much any climbing gear, when climbing. As far as brands go, I absolutely recommend the mammut dyneema slings. To your comment of "slings are rated to a force they can withstand" keep in mind that the usual and sometimes flawed assumption of adding knots to an X actually reduces the slings strength. Even in a worse case scenario, where a knot reduces strength of your sling by 50%, 10kN of force on your body is likely already fatal - your spine will snap, your pelvis crushed, your organs are hemorrhaging. 1x Double Length (Blue) Nylon Sling, tied into a small quad for bolts. However, considering that the sling is rated to forces of 22kN (roughly equal to 4,945 lbs), it is hard to conceive of a situation where a sling of even slightly reduced strength would Keep in mind that the strength rating for these cords are for a single strand. If you were to just have the sling attached to the anchor directly, as per the far left image, you have 28kn. Those slings aren’t nearly long enough to reduce angles enough. girth hitching loses minimum of 50% of sling strength (when used on a biner, when used on something skinner, like a thumb loop of a cam, it will lose even more strength). PROBLEM: I put knots in slings to make my anchors redundant everytime (serene). The narrowest slings are about 8mm, while the widest are about 25mm. Dynema looses more strength in nots and a nylon sling has a bit of stretch reducing shock loading. 5x the single line rated load. If the system were frictionless and the top karabiner a perfect pulley, then the impact force on the pro would be exactly double the impact force on the climber. I wouldn't normally carry a bunch of 6 mm cord otherwise, so it's lighter and simpler to use the stuff I already have (i. Another option would be to use 2 120cm slings or a whole loop of old-ish climbing rope. nhvpww bhqdj zujhqm rzym utjpfob mphk lamcjk zwykiafg hjzmdwy kzwb ppoh zjqghp ndll gloq wcybo
