i absolutely love belaying with my cinch, but have never self belayed. do you have to pull the rope through as you would on a gri gri? I have used a mini traxion and feel like nothing could feed easier than that. I might have to give it a try

I hope you're reviewing the Ushba basic ascender. It's a great solo TR device. Super smooth.

I friend of mine has a Cinch & one time, she got jerked upwards while belaying a falling climber & the Cinch would not allow her to lower herself back down to the ground while weighted. It only releases when there is not weight acting upon it. The climber she was belaying has to bounce up the rope & hang from a draw to get enough slack in the rope to allow her to release the Cinch.
For this reason, I suspect the cinch may not work well as a solo belay device because if you fall,you won't be able to lower back to the ground or to a convenient ledge or stance. The Gri-Gri works so much better in this case.

well, after reading through the Trango web site i got my answer (below):
Question: The Cinch looks like it would be awesome for rope soloing. Can I use it for that?
Answer : We can not, under any circumstances, recommend the Cinch for soloing, either TR or lead. We've done an enormous amount of testing on it, all to get it dialed for belaying and lowering rock climbers. We haven't spent one second testing it for soloing. So, if you do try it, AMFYOYO. Here's the way my lawyer wants me to say the same thing... The Cinch is not designed or approved for solo or self belaying under any circumstances. Using the Cinch in this manner can result in death and/or serious injury. Other uses for the Cinch have not been tested and are not approved uses. The Cinch was not designed as a self belay device and such improper use is potentially fatal. The Cinch is designed, sold, and approved for use only as illustrated in the pamphlet that the Cinch is sold with. Use of the Cinch in any manner not illustrated in that pamphlet can result in death and/or serious injury. The user is responsible for learning the correct way to operate the Cinch and operating the Cinch correctly. The user is responsible for any and all death, injury and/or risks arising out of his or her use of the Cinch. If you do not accept this responsibility, do not use the Cinch. THE MANUFACTURER AND RESELLERS OF THE CINCH EXPLICITLY DISCLAIM ANY AND ALL RESPONSIBILITY AND LIABILITY FOR ANY DEATH, INJURY OR DAMAGE TO ANY PERSON OR PROPERTY THAT MAY OCCUR THAT IS RELATED TO THE USE OF THIS PRODUCT.

Chris,
Are you rigging the Mini-T with a sling to keep it upright, or just letting it drag between your legs? I was trying out some variations yesterday. Had a fat rope on short steep routes, and it wasn't running very smooth for me. Had to tie on my shoes or a coil of rope to weight the bottom. Folks were recommending the shock cord to keep the mini-T upright. Without it, you fall about a foot and a half or so onto the Mini-T, which I didn't like. This was just a major pain in the ass though, rigging one way to go up, then reconfiguring to get back down, and repeating. I ended up just using a gri-gri on the last few routes, but it sucks pulling slack.

well doesnt the minitraction say the same thing about rope soloing?
sound pretty promising to me.

since the cinch doesn't adjust diameter wise, I suspect different size ropes will result in very different handling characteristics.
I have a friend with a cinch and he claims they put a bad kink in the rope (when used as a regular belay device). Not sure why that would be, but that's his claim. Anyone else have any experience with the device?
yea, I suspect the legal verbiage doesn't add a thing to our knowledge. Just covering their ass.

I'm sorry Mal ...but that cinch is a piece of sh#t. If weighted you have to mantle onto the small trigger to release it, Poor design, but it feeds ok when lead climbing but to solo...Your gonna die. If I haven't already given my cinch away to Mister E or someone else it's free for the asking.....What a waste of phucking $.

I've tried the cinch quite a bit for soloing, and as a way to have a third follow and self belay on multi pitch routes. I stopped doing it because it can fail to lock in certain orientations or with light loads such as slab falls. Much better backed up. Feeds much easier than a gri-gri, more like an ushba. very useful as a rigging tool.

Wow, Chris, I'm way surprised to hear that the Cinch feeds so well! Cool to hear it, though. I guess I figured it would work similar to a Gri Gri; I saw someone use a Gri Gri once for solo-toproping, and it did not feed on it's own at all...he had to feed it by hand. I've done tons of solo-toproping for many years, have tried just about everything on the market...except the Cinch. My current favorite setup is TWO Mini-Traxions, with Belay Master 2 carabiners. One on my belay loop, one on a half-runner girth hitched to my harness. Personally, I do not feel comfortable using one of any device for this purpose. I think solo-toproping is the safest form of climbing that I do. Yes, you are alone (not always, though...oftentimes other climbers are around). But there is simply no way that two Mini-Traxions are going to fail at the same time! You don't have to rely on a belayer, you have rapped the route first to check for any potential loose rock...so why not make it mega-bomber with TWO devices? I used to use the smaller USHBA ascender as my primary unit backed up with a Mini-Traxion. That seemed even more redundant, not only being two devices, but two from two different companies...perhaps the Cinch would be nice for the same reason, backed up by a Mini. Still, though, the Mini's slide nicer on the rope, and it just seemed possible to load the USHBA in a way where it could slide down the rope. I did mod my top Mini, it's pretty easy to cut off the cam lockout with a Dremel. This does seem like a substantial flaw to this device for solo-toproping use; you can accidentally have the cam locked out. Just curious, how does the Cinch perform for rapping? I was using a Gri-Gri, but it seems annoying to modulate. It's either on or off, poor control. I now use a Metolius BRD, highest friction of any device like this, and most raps I tie a knot maybe 15 feet down in case I were to lose control of the rap at the start of a cliff.
Anyway, solo-toproping is a gas, is super safe, fantastic workout for those days you can't find a partner, or just feel like being alone, working a route, dialing your technique, getting a lot of pitches in, climbing when it is cold so you keep moving. It requires minimal gear, is quick and easy to set up, and is bomber...I strongly recommend using two devices, whatever you choose...there is simply no good reason not to! It reminds me of toproping with somebody I can barely remember about 25 years ago in Josh. He set the anchor, we did some laps and I was last up and took the anchor down. He had in about a dozen pieces, made a comment that there was no excuse for toproping to be nothing but insanely bomber. I agree.
Here's a photo of my Mini-Traxions, the one on the right has the mod I mentioned to remove the cam stop.
Enjoy! This is a great way to rock climb. It's ironic because people will see you and think you are doing something way crazy...NOT!!! I went to the Sunshine Wall at George (Frenchman's Coulee) last Wednesday and did 10 routes (5.9 through 5.12a) in 2:33 car to car...gotta love that!

what are you guys doing where you can't release a Chich? I have had one for a couple of years (one of the first generation ones) and have never had a problem releasing the rope, even while hanging or being lifted off the ground while belaying. I think the thing is great, it feeds better than anything else I have used.

The Cinch rules, I own 2 and love em both - but I think, as Malcom says, that it should not be used for solo self belay. I have, despite my admonitions, utilized it for TR solo in that capacity, and of course kept my back up knots close and short. I am suspicious that in a self belay fall, if the Cinch got pushed up against the rock and your belly, it would not lock up. It's more of a feeling. When the Cinch droops down, it will not lock. This is the same thing a belayer does when he is giving out slack fast with the device, just change the orientation so you can strip out line for the leader to clip. If the device doesn't reorient when you fall it WON'T lock......ouch.
I have had great success for regular climbing, never had an issue with it not allowing the rope to run either in lowering a person or in using it to rappel a single line, which I did a lot this summer.

Off-axis loading of the ostensibly stronger Pro-Traxion during my use (for hauling, not self-belay) resulted in near-catastrophic cluster-fuqcing. The rope got between a side plate and the sheave, and wedged almost irreversibly.
I guess if you're going to fall on one of those things, and it saves your life, you don't care if the mechanism gets locked up solid, as long as you live.
The design failure of the Pro-Traxion is the lack of lateral stiffness between the side plates and the sheave. The design is wholly acceptable for normal (i.e. 2-d) loading, but odd, strange, off-axis and generalized 3-d loadings can result in non-linear behavior. Specifically, a gap can be created between a side plate and the sheave, sufficient for a rope to enter, and get stuck.
I would never have believed this to be true, looking at the mechanism, and how well it was made. But, in The Real Life, this rare failure absolutely reared its ugly head, on the Wall, in the Real World. Getting the rope out of the cluster-fuqu was a time-consuming headache; getting back to nominal vertical freight hauling was an additional pain.
I'll NEVER, EVER haul against a Pro-Traxion again as long as I live: try it once, and I'm a fool; try it twice NO! I am not that degree of fool. And, here, I don't need to make claims or creech like a madman. The Kong Block Roll is available, and is, totally, the schnitt.
I guess my take on soloing with a mini- or ProTraxion goes about like this: it can have a failure, but will stop the rope from running because it tends to lock the rope up, solid, at the non-linear extrema of its usefulness.
In Other Words: the Traxion family of devices might not drop your ass, but might irreversibly engage your rope.

Great point, Tom! Like I have said, this is why you should never trust ONE of any device for solo-toproping! Weird sh#t can happen.
You would not be Tom Davis, would you? If yes, I climbed with you a few times back in 86-87...
