i read that as well but what about alica and the reports on 8a about expeirenced belayers using it properly and it still failing?

whoa... ya had no clue about that! um scary. i would say in most belay accidents it's likely human error but the Chinch seems to have that plus documented gear failure due to wear. I'll side with safety and limiting my risks as a priority above how easily the rope slips the wrong direction through the device so I can give my leader rope. Seems more important that I be able to take in that slack and hold it in rather then feed it out faster... no?

folks ... remember that the cinch is really a minor niche device in the scheme of things .. you arent going to find any "real" significant statistics

in the DAV study it constituted 1% of the devices but accounted for 7 accidents in 1 year ...

heres a shietty translation

"Seven accidents when you save the
Lead climber in a year are frightening.
All malfunctions.
They lie in the complex operation
the unit justified: since the
Cinch has no spring, you can
only spend rope when
the machine "open" holds. the straight
Cable passage reduces friction
almost to zero."


by now its likely that the smart, gri gri 2, click up, etc ... are pushing the cinch into obscurity

of course there are probably more cinches in the good ole USA ... however even up here in vancouver/squamish, there has been several more times smart/alpine smarts the last few years over the cinches ... the smarts up here are fast becoming the runner up to the gri gri for assisted locking from what i can see at the crags and gyms ...

IMO with the gri gri 2, and the smart ... theres no reason to buy a cinch these days

Look at the GriGri 2 video from Petzl and notice how everyone grabs the lead rope in anticipation of a fall. It's not a failure point for the GriGri. They also say don't grab the lead rope as if to arrest the fall with your hand, which was not what I was doing. I was grabbing the rope to steady myself in anticipation for the fall and you need to have a certain firmness on the rope to do that.

I think it is natural to grab the lead rope when belaying. If that's a failure point for the Cinch then it violates one of the principles mentioned here:

mountainproject.com/v/warni…

"belay devices should not require use, or be used, in such a way that is counter to human emergency reflexes (an example of such a reflex is the tightening of grip of whatever you are holding at the moment of a sudden emergency/scare. Holding the Grigri cam open with your left hand while pulling rope with your right is an example of such a use)."

because no one corrected you when you first learned to belay. natural to fearfully grab things yes ill grant you that but especially if you expect a fall both hands should go to the braking strand. if you need to steady yourself then you have also failed to find a good spot to belay from initially which is yet another sign of poor form.

im culpable as well. we can always do more to be aware and sometimes going back to basics is beneficial

cool. Maybe you should go and correct all those pro climbers in the video and thousands of climbers out there while you are at it.

I'm not telling you to do anything just suggesting that assessing how we do things from time to time is beneficial to keeping everyone on their toes, avoiding complacency, and truly minimizing the risks we take.

FWIW pro climbers do a lot of things that do not necessarily present safety at its finest.

I didn't grab it to with the intention to stop the fall with my bare hands. I mentioned this many times.

What do you think of this ?

I'm starting to prefer my mega jul to my gri gri. The mega jul works on a similar principle to the smart. I've never had anything like the problems claimed in the video. Accidents like the one described are almost impossible with the mega jul because even if it fails to auto lock, it works like an ATC. It's also designed to be reversed to work exactly like an ATC ... and it's lighter than an ATC.

Find that for me on the Petzl website...it's not preferred but it ain't a big no-no. The only no-no is to NOT grab the brake end of the rope during a fall. For any device other than the Cinch, nothing bad really happens if you grab the lead end. At most you may burn that hand a bit, but you are not going to drop the climber.

Since your lead hand needs to take in or feed slack, it's counter instinctive to have to release the hand arresting a fall.

No offense taken. I shared my experience to warn people about the Cinch. I have made my points and we disagree. It's fine.

accidents are certainly possible with the smart

i know of one drop and an almost drop told to me by people i climb with ...

ANY assisted locking device can "fail" ... that said the smart is simpler and more intuitive to use

the most common way is to hold the cam/lever and then the climber falls ... even if the cam/lever closes the person can drop 30+ feet in an instant ... ive seen it

for the smart this can be avoided by ONLY opening the device when feeding the rope, and being trained for the brake hand to move INSTANTLY to grab the brake fully ... ie hand off the device totally and only on the rope ...

same with the gri gri

also for the smart lift the lever outwards, not upwards ....

what gets me is when i see people being trained to catch in a fall ... i dont understand why they dont teach em to bring BOTH HANDS ON THE BRAKE ...

this would stop a lot of belay accidents ...

Ive give plenty of dynamic belays where both hands went under the atc

In fact with a ligher person its safer to do that so that the top hand doesnt smack and get caught on the first biner if she goes flying up

Seen that happen too

I owned a cinch. It wore out, quickly I might add. Once it wore out it began failing as is typical of the device. I switched to the GriGri2 and am still using it many years later with no issues.

If you want to use a device that wears out quickly causing it to fail, the cinch is the device for you!

Maybe it's just me, but I fail to see the logic in that, especially without those "real or significant statistics" that can't be found- aka actual evidence to substantiate a claim.

There's enough anecdotal evidence on this thread to make me uneasy on the idea of being belayed by a cinch. No matter how competent the belayer. I know from experience that at least a couple people here reporting slippage are good climbers, solid belayers, and have demonstrated excellent knowledge of rigging systems. So hearing that it failed on them is not encouraging.

It works until it doesn't. Then you're fucked. Might as well use a different device. Not worth the risk.

Mal no longer works for Trango so he isn't as active in discussions about their stuff as he used to be. I think his work with Paradox Sports is far more important.

Jake Jones wrote:I agree with you Jon, and for the same premise. I guess I'm just not as uneasy about it because it has never failed me, and with little empirical evidence (disregarding claims such as the OP's that can't really be verified or recreated) to suggest that one day it will just happen out of nowhere. I've belayed with a Smart, and it seemed funky- I can't really be more descriptive than that- but I guess every device to a new user is that way at first. Maybe I'll pick up a GriGri2 and see how I like it. I understand completely the stance that this shit doesn't just happen for no reason, and at least some percentage of these accounts probably hold water. Still though, seeing is believing, and it's been an excellent device for me, so I remain reluctant. It can't hurt to try other options, though, so I suppose your point is well taken. I would be interested in hearing Mal Daly's take on all of this, although it has the potential to be a bit biased.

Watching the Petzl instructional video again, it says around 1:47-2:00 mark, "that the GriGri should be used like any friction plate device, with one hand on the climber side of the rope, one hand on the braking side of the rope. This is the principle belay position and you must also adopt this belay position."

Since I haven't dropped anyone using a tube style device, the answer is no.
