It almost goes without saying that some of what appears here, and on other climbing sites is 100% BS. Here's my list of the biggest turds. In no particular order... - When fitting shoes, the tighter the better. But hey, it keeps those sweet deals coming on EBay. - Never take rope in when catching a leader fall. Foot, meet ledge. - Nylon loses 5% of its strength each year due solely to age. Quick, someone alert the rope manufacturers! - Dropped gear must be retired due to the risk of microfractures. A perennial tackle box favorite. - Fall Factor determines the peak load on gear, the climber, and belayer. Yup, that's it; nothing else matters. - Toproping on static rope will get you injured. A classic case of, "No, I haven't actually done it. I just know it's a no-no." - Expensive cams are safer than the cheap ones. Usually something along the lines of, "You don't want to look down that long run-out and see a $29 unit down there." Hey buddy, I got a $200 cam to sell ya. - Home-made or modified gear will kill you. Riiight. There are no more improvements possible. Ever. - Gasoline, oil, WD-40 will damage nylon. Caution is prudent. Blowing smoke out your a$$ when you don't know what you're talking about OTOH... - TR self-belay with a toothed cam ascender will shred the rope. (see TR on static rope.) - Place Tricams and large SLCDs with the rails or wider lobes on the bottom. Like tipping over is even possible! - Never clip metal-to-metal. Pitons and bolt hangers = instant flying biner shards.

AGREED About the tight shoes comment everyone online said to get the five ten anasazi moccasyms 1 to 1 1/2 smaller than my street shoe. I ended up having to send mine back for a replacement of one size bigger than my street shoe.

In reply to: - Dropped gear must be retired due to the risk of microfractures. A perennial tackle box favorite. I hear that one way way more at the crag than online where almost everyone agrees that micro fractures are not real.
In reply to: - Expensive cams are safer than the cheap ones. Usually something along the lines of, "You don't want to look down that long run-out and see a $29 unit down there." Hey buddy, I got a $200 cam to sell ya. I don't think anyone says that.
In reply to: - Never clip metal-to-metal. Pitons and bolt hangers = instant flying biner shards. Once again, something I hear at the crag but rarely online.

In reply to: - Toproping on static rope will get you injured. A classic case of, "No, I haven't actually done it. I just know it's a no-no." The gym I go to used static ropes for a bit, and while they lasted much longer than a normal gym rope, I quickly became "that guy" that kept asking for rope to be pulled in...even short TR falls were much more uncomfortable than a good lead fall.
In reply to: - Place Tricams and large SLCDs with the rails or wider lobes on the bottom. Like tipping over is even possible! I agree with this one...unless the placement is better with the wide lobes up, you could have some twisting forces on the head.

I agree with most of the things on your list, but suspect that many of them were myths either before or independent of the internet. I also think a couple of items on your list are a little questionable, at least the way you have worded them. For example, top-roping on a static rope may not get you killed, but isn't necessarily a good idea--unless the route being top-roped is so high that the stretch from a normal dynamic rope could result in the climber decking near the start of the climb. Also, your comment on fall factors is worded somewhat curiously. Fall factor does determine the forces involved in a fall--with all other things held constant. Naturally, a 50kg climber and a 100kg climber will generate different forces even if the fall factor is the same. Good list though. Curt

New belayers + new climbers + 60' toprope route = potential injury on a dynamic rope if the climber falls before they get 10 feet off the ground.

And yes they are fine for toprope. I have even climbed on static rope outdoors when someone else was using one.

Not sure where people are getting this notion that a cheap cam is as durable. Hell no they are not. I've fallen every bad way on Aliens, Camalots, and Friends you can imagine. I've only one rendered a blue alien unusable. In fact, it'd be fine for $8 if CCH was still in business. I've had a lot of RE Pulsar cams. They didn't last as long. One of them I broke the aluminum keeper bar in a single fall. This rendered it useless but yes, it was still just as strong. The other ones stopped pulling smoothly once the cable got even the tiniest bit of tweak. 2 days of dirt also made them nearly impossible to use. This is side by side to Camalots and Friends and Aliens that got cleaned up once every couple years and withstood way more abuse. Certification strength is not any sort of guarantee that you're buying good gear. Just that your gear won't break when you fall on it.

Not to mention that it is almost always easier to get a more expensive cam to fit properly in a placement (BD is the most obvious but not the only, example). Beyond "Never die," I have found that "ALWAYS" and "NEVER" statements regarding rock climbing tend to be in the realm of the gumby.

Not necessarily an elitist statement, just think of our gear use as two points on a bell curve. BTW, if you want to see what your designs can do for a couple punks in Greenland, I'll give you my address and pay shipping. I'll even throw in a Bermuda T-shirt or coconut or some pink sand or something.

You only really nailed it on the first one and as several people have mentioned, you're perhaps more likely to hear some sales person at REI say that than you are if you ask that in the gear forum (almost everyone their, zombie-like, tells you to get what fits, which can be equally bad advice).

If they're UIAA Certified they've been tested by a third party testing facility per the UIAA125/CE12275 specification, so by definition they all are tested to the same standard. How much they exceed the standard is an altogether different question... and therein lies the problem.

It's definitely misleading to have you, the gear guy, essentially say that all UIAA certified cams are the same. How's that? If they're UIAA Certified they've been tested by a third party testing facility per the UIAA125/CE12275 specification, so by definition they all are tested to the same standard. How much they exceed the standard is an altogether different question... Granite girl makes a good point. UIAA doesn't test specifically for quality. there are mostly testing strengths of the gear. Really how many cams in 1000 are tested?

I think that the greatest internet climbing myth/falsehood is that unless you can climb 5.12 or 5.13 or V10 or whatever, then you aren't entitled to have an opinion regarding certain subjects. "You only climb 5.11. Come back when you're climbing 5.13 and then you can comment, noob" I'm never going to climb 5.13 but, after 20+ years of climbing, I feel I can make a comment on most climbing related subjects. Even if I had only been climbing 20 days, I am still allowed to comment on a subject, without some grade obsessed sycophant telling me to shut up, because I don't crank V10 and I don't know Tommy or Joe or Bill or whoever. It's called FREEDOM OF SPEECH. This seems to be a particularly American attitude and it is particularly rife on this site. I don't really see it on forums in the UK or here, in Australia. What amazes me is, these ego-stroking sycophants don't even realise how dumb they are making themselves sound. You don't sound hard and smart. You sound like 'A' grade butt kissers. Climbing 5.13 does not mean you are smarter, wiser or more able to make a comment. It just means you can climb 5.13. And that you probably spend too much time climbing plastic.

Does climbing 5.13 mean that you might have more mileage on the rock than the 5.10 or 5.11 climber? Not to refute your point but so often the sound, reasonable, and seasoned comments are ignored by some loudmouth who's been climbing for 2 years. How am I (or others) supposed to react? There were a lot of things I thought I was right about 2 years in that I was completely wrong about. The grade shouldn't be the issue, experience should be. Then again, experience gets conflated with years climbing and the word experience loses meaning.

With climbing gyms being on every second street corner, nowadays, no, it doesn't necessarily mean you have more mileage. These days we have 8 year old kids cranking way harder than lots of "seasoned climbers" every did or will. Does that 8 year old cranker have more right to pass comment because they have climbed harder?

There were a lot of things I thought I was right about 2 years in that I was completely wrong about. That's what I am saying. It is very common now for someone who has only been climbing for a couple of years to climb hard sport routes or blocs. Indoor gyms give lots of opportunities for young climbers to get into the game and climb and train a lot. Improvement often follows rapidly but wisdom does not.
angry wrote: The grade shouldn't be the issue, experience should be. Then again, experience gets conflated with years climbing and the word experience loses meaning. Neither should really be the issue. If you feel you have something to say regarding some subject, you should be able to say it without fear of being told "come back when you can crank 5.13" or "come back when you've climbed as much as I have". If said person makes a stupid comment, it becomes immediately apparent and they look like a dick head. It's kind of like natural selection. I feel fine with people pointing out that someone has said something stupid and look like a dick head. What I don't feel fine about is someone chiming in and saying "you don't have the right to say that because......" As far as I'm concerned that's just adding another dick head to the equation. An elitist, head-up-his-ass dick head. And , Angry, I was particularly impressed with your little dig about experience being confused with years climbing. Well done mate!

I am pretty sure most people say they are not a nice cam but not that they are unsafe. All brand new cams are completely safe. Apparently, knowledge about some Gear4Rocks is Alien to you.

Do you really want to trust just me because of my experience? I think that intelligence is more important than ratings and years on the job. Maybe we need to start using the words "wise" and "wisdom" to describe that desirable trait that makes one worthy to give advice. Dave Being intelligent isn't the same thing as having wisdom. I know some really smart people who I wouldn't trust to know anything about climbing safety because they just don't know it. Relevant experience is where I would put my money. Intelligence helps, but by itself is not entirely reliable.

In one summer it's possible to road trip for a few months and accrue the equivalent of "two years" (or more) worth of experience. not to mention, climbers tend to have rather inflated ideas about the number of days they actually climb. a similar argument applies to experience and difficulty.

Years and grades don't denote experience but the quality of the experience. I hate to say this (since this is a vast generalization) but it often occurs when someone doesn't step outside of their comfort zone, so they never improve. (but hey I'm being elitist again). Now does an "experienced" climbers point of view any more valid then a beginners. Depends on the subject. If it is on gear placement, risk analysis,.... damn straight experience counts. If its on value subjects, then the beginners and the experienced persons point of view is just as valid.

I'm saying that there is alot of information out there, on both sides of the issue. Some very reliable sources say that gasoline(and the other chemicals mentioned) have no negative effect on Nylon. Some very reliable sources say the exact opposite. Some sources say that Nylon is extremely resistant to UV degradation! We've all seen how that works out. So what I'm saying is....if multiple different and reliable sources give completely opposing answers, how can it be called a myth? I'm not planning on soaking any of my nylon climbing bits in any chemical. josh

It's been a while since this one made the circuit, but for a long time the idea that marking your rope with sharpie would damage it was coming up every couple of months on internet sites. GO

You'll find Nylon in there. Then go search the rope manufacturers' sites. IIRC at least a couple of them mention that gasoline won't hurt ropes. Then go check the general chemical literature for polymer-solvent compatibility. See how those sources stack up against the Net bloviators who preach gloom & doom re. gasoline.

All three components failed above its rating.

i'm no chemical engineer, but - nylon 6,6 is repeating units of hexanedioic acid and hexamethyldiamine. i would expect properties close to hexanamide. since the ropes can work when wet, i'll assume the alpha carbon isn't susceptible to a hydroxyl attack, even assuming acidic conditions (acid rain, anyone?). however, i can't shake the feeling that 6 carbons is a long way from polar, making gasoline (all 50 bajillion constituents) a possible solvent. gasoline being mostly simple branched alkanes from as short as butane to octane. from a simple google search, it looks like a few methyl branches, but nothing too fancy, with only a small amount of aromatics. the aromatics are also cause for worry, you can never trust those pi clouds - but aromatics are usually indifferent. i'll leave it as a question for the chemical engineer, what is the gibbs free energy of benzene (or methylbenz) with hexanamide, ketones or secondary amines? furthermore, it's not clear to me that climbing rope is made of nylon. the industrial term 'nylon' covers too many polymers to be elucidating - so i'm sure there is some version of nylon that's resistant to gasoline. polyethylene and aramids are common place in climbing ropes. at this point, gasoline could disrupt some of the pi bonds that aromatics use to stack. whether or not this effect is significant is beyond me - but even if it were significant, it'd only reduce the kevlar to the strength of nylon 6,6 (assuming no other RxNs). maybe the chem eng would know - or maybe somebody needs to go outside with a rope, some gasoline and a 200 lb weight.

I'm not a chemical engineer but my PhD is in polymer chemistry (ie: plastics). the nylon used in climbing ropes is nylon 6,6 and you are right about the consituents, except its really hexamethylenediamine. the main component of gasoline, the octane family (n-octane and its isomers) is not an issue with ropes since it will neither solublize it, swell it, or cause any reaction (which is the same thing about the Sharpie pen in the formulation that it was tested in). Things that will swell, or dissolve nylon 6,6 are things like the cresol family of solvents (p-,m-,o-cresols), anhydrous sulfuric acid (I would expect that sulfuric acid from battery acid would also induce quite a bit of oxidative stress) or other highly polar solvents. Mylon consists of amide bonds which undergo significant hydrogen bonding between the N-H region of an amide on one chain with another C=O region on another chain. The highly polar solvents listed above allow breaking of those amide hydrogen bonds, (also doping it with lithium chloride does the same thing but not too mny people carry LiCl around with them). Non-polar solvents such as octanes unable to do it. The linear chain also induces significant packing which dissallows for polar protic solvents such as water and ethanol from affecting it significantly. Its really the polar solvents such as cresols, DMSO, HMPA, DMF, DMAc, anhydrous sulfuric acid,..... that are significant players. Having said that, to assume that gasoline is octanes is false also since while its a major constituent, it also has a shitload of other contaminanents and additives, some dependent on where it was extracted from (this is outside of my field since I'm not a petroleum chemist), so I won't say that its ok to soak your ropes in gas or that splashing gas on them is ok either given all the other crap in there. I won't say that Sharpie pens are innocuous either. In the formulation that was tested, it was found to be inert and doesn't affect rope strength, but the manufacturer of Sharpie can change their formulation at anytime without having to notify anyone, so the carrier of the dyes today may be inert, but who knows what is used tomorrow.

It seems like these are all such old myths. Maybe a new myth. Something like "The reason two biners are set opposite AND opposed in a top rope anchor is to ensure that the static charge in them built up during lowering flows in opposite directions negating the charge thereby avoiding a dangerous spark."

Jay Considering that the terminal velocity of a much more aerodynamic object (namely, a tumbling bullet) is so low, I'd wager that there isn't a considerable difference between 100 & 300 feet. Of course, heavier carabiners have higher terminal velocities, so maybe dropping steel carabiners from 300 feet up might be different from 100 feet up. Also, didn't BD do a study on crabs found at the base of El Cap? Like 15 years ago? And found that, uniformly, if a carabiner was in good working order it failed at least at its rated strength? By the way, the sharpie middle mark thing, while perhaps dangerous in principle, requires the climber to have run out half the rope length and then fall with the top most piece connecting to the rope at precisely the middle mark. So you're looking at AT LEAST a factor 1 fall, probably more, but with a ludicrously small margin of error to have the sharpie middle mark even factor in. If you expect to encounter that sort of situation, you'll know it ahead of time and will plan accordingly. At least, according to the UIAA study on it from a few years back.

OK if I follow this then gasoline is OK but additives may be trouble.] Would it be OK to use white gas (fuel for Coleman cooking stoves) to wash rope and slings? Gas is great degreaser and should really clean the rope up nicely, and I don't think white gas has any additives. Similarly, would it be OK to dry clean rope? Seems like dry cleaning is for sensitive fabrics and so it wouldn't hurt the rope. Thx.

That's incorrect. The reason you opposite and oppose them is indeed to create opposite current flows but the purpose of that is to negate the magnetic field in the center so that it does not act like a solenoid and thereby shoot the rope out of the biners.

Don't know whats in white gas, as I say I'm not a petroleum chemist and I don't think my employer would appreciate me sending some over to Analytics for a GC-Mass Spec analysis. Go to the manufacturers website to see what is acceptable for Nylon 6,6. And I have no clue what is used for dry cleaning fluids. My attitude is I know that the major constituents don't matter but unless I end up sending samples over for pull testing I have no idea and I'm too lazy at work since I have too much stuff to do anyways.

it would be nice if you list some of the typical chemicals that most climbers may have on them as potential hazards to watch for such as aftershave, sun-lotions, other stuff that we regularly pack in our bags while traveling to crags. I travel overseas with tons of stuff and put many of my personal stuff along with ropes and webbing or whatever so its good to know where to keep things in the compressed backpack.

Seems like dry cleaning is for sensitive fabrics and so it wouldn't hurt the rope. Thx. White gas is a fairly simple mixture of light aliphatic hydrocarbons and smaller amounts (<5% in Coleman Fuel when I analyzed it) of aromatics. It evaporates quickly and completely since the molecular weights of these HCs are on the small end of the gasoline range. There is a small amount of blue dye and antioxidant added, but I wouldn't worry about either. Dry cleaning fluid can be a petroleum distillate called Stoddard Solvent, which is like kerosene, and won't harm Nylon. Or it can be a chlorinated HC like perchloroethylene (AKA "Perk"). I am not so sure about that, but given that nylon fabrics evidently are not harmed by being dry cleaned, I suspect it's OK on ropes. YMMV but I would not "clean my rope" in white gas or dry cleaning fluid. While I believe these are harmless, intentionally putting large amounts of it on your rope is a bit like dancing all over your rope with crampons on because someone proved that stepping on a rope w/crampons doesn't hurt the rope.

OK, thanks for the info. I'm guessing the white gas may totally remove dry coatings as well, so that may be another reason not to do it. I will stick with my rope brush and bathtub, I suppose, but I'm not 100% happy with the results.

Full size biners can hold more charge than mini's. Ovals allow symmetrical electron flow for better oppositional cancellation. Of course, the effects of annodization have not been well studied. I'd say you should check each manufacturers literature for the tested values.

Most gyms I've been in use what's marketed as "gym rope", which is a rope with a high fraction of the weight in the sheath (so it lasts longer). These lower stretch gym ropes are *very* different from true static ropes. Static ropes have a stretch of less than 6% at 10% of their MBS, and often have as little as 1 or 2% stretch if tested in similar conditions to the standard "static" test for dynamic ropes. They may even have low stretch material like polyester in place of some or all of the nylon. Gym ropes, on the other hand, are essentially standard dynamic climbing ropes, but with a beefy sheath. Typical gym rope: http://www.sterlingrope.com/...246835/GR/_/Rock_Gym Typical static rope: http://shop.pmirope.com/...;productMasterID=677 GO Exactly! I've been to 5 of the 7 gyms in my area, and all of the ones I've been to use these: http://www.sterlingrope.com/...246835/GS/_/Slim_Gym

Guys, Knock it off!!11 My opinion is that the only way you'll get RF emissions is if you have gate flutter that is fast enough to cause make-break in the circuit at speeds that approach radio frequencies. Hence, I don't think that the FCC has provenance here. However, just because the phenomena doesn't come under the FCC's jurisdiction doesn't mean that it shouldn't be understood.

The gym I used to climb at used to have a healthy, if somewhat hodgepodge, mixture of dynamic, gym, and static ropes. The gym ropes are much more akin to the dynamic ropes than they are to the static.

But that is not what you have linked to below. That is an ordinary dynamic rope. It has 10.6 kN impact force. It just has a beefier sheath, so it is more durable. Jay

For example, top-roping on a static rope may not get you killed, but isn't necessarily a good idea--unless the route being top-roped is so high that the stretch from a normal dynamic rope could result in the climber decking near the start of the climb. Also, your comment on fall factors is worded somewhat curiously. Fall factor does determine the forces involved in a fall--with all other things held constant. Naturally, a 50kg climber and a 100kg climber will generate different forces even if the fall factor is the same. Good list though. Curt Yeah, I've heard most of those myths back in 1996 before the internet was very big at all. In fact, most of those myths have actually been dispelled by the internet itself. Well, for me at least.

As I've said, I'm not denying that some gyms use static ropes. Hell, I once worked at a gym where I was responsible for the purchase of the static ropes for them. But IME, such gyms are a tiny minority. So like I said at the start of this, I'm curious, and would be interested to hear some examples. For example, what's the name of the gym or gyms you climb at most frequently? GO
