Black Diamond Neutrino Carabiner

Haven't used them for climbing yet, but used them for several non-technical uses (hanging hammock, slinging stuff off my pack, etc.) and they've been great.

I love this biner. Just big enough to clip easily and still very light. I like this biner a little better than the Oz biner because of it's size. I have found the Oz biner tougher to clip (especially with gloves on). The neutrino is great for slings, draws or cams. From alpine climbing to sport climbing I prefer this biner for its lightweight and perfect size.

Pros:
• Light
• Perfect size
• Color coded (matches camelots)
• Easy to handle
• Easy on the wallet
• Easy to clip

Cons:
• Occasionally snags on the hook side of the gate, but that comes with the territory when it comes to wire gates.

These things are awesome. Definitely a good idea to pick up a set if you're building a rack of camelots. Having the color coded biners is amazing when you're fumbling for that number 2 cam while slowly greasing off a gnarly sloper. All you gotta do is grab the yellow biner and you're golden.

Nice and light, compact size, smooth wire gate. Use these for racking gear and on alpine draws. They're pretty small so racking a cordalette or bundling a long sling on them is a little funky, but are perfect for storing individual cams, etc (see the Neutrino multi-pack, which is color-coded to match the C4's #.5 - 3).

This carabiner is average in every single way. It's neither big nor small, light nor heavy, fancy or plain. What it is though is a cheap, durable, and simple wiregate carabiner that you can color code to match your Camalots. If you need more biners, stock up on these, you won't regret it.

nothing wrong with these guys! like everybody else, i love the colors. these biners are super burly and super lightweight and easy to use. just when i thought i had enough, i run out and need more--good thing they're only 6 bucks!

A well made and very light wire gate biner that works well for trad draws and racking cams. I definitely wouldn't consider these for sport draws due to the small size and notched nose, but when you need to carry a giant trad rack full of biners all the way up a mountain, these are tough to beat. Plus, the price is right, especially if you need a bunch of them.

Super Light and a good feel when clipping. Can't complain.

Like everyone else, the size and weight of this carabiner, combined with its relative strength, make it one of the best out there. Good for putting on just about anything where you want to save some weight.

I'll have to agree with Renan, James Watts and Andy Jacobsen here. The Neutrino is great.

This biner while a little smaller than some is great when I'm leading with a thinner rope (less than 10.0 mm) and want to keep my rack weight down. The gate action is a little stiffer than some other wire gate biners but still feels smooth and clips nicely. Can't wait to get these on some ice and put the freeze-proof to the test.

Quality light weight biner that can speed up locating pro. I agree that the gates are a little stiff, but i have never gotten into a bind over it. Recomended

Buy it, color coordinate with your rack of C4's, go on with your hopefully merry life. Neutrino 'biners are small and ideal for a light weight, full strength racking 'biner. I don't how much you'll actually notice a few ounces less weight on you, but the thought of less weight is nice.

From one Limey climber to all the folks on the other side of the pond...like you I like the Neutrino: it's easy to clip and is nicely made, but what sets it apart from (too) many others is the shape - the relatively flat lower part of the 'biner makes it an excellent choice for racking gear. The almost triangular shape of most of the currently available 'biners here in the UK makes them nigh on useless for racking wired nuts. Using Neutrinos for racking wires has made a world of difference - they don't pile up on top of each other and, consequently, the wires are quick and easy to place. Top-notch gear.

As said before, it's a great biner. Especially for racking the BD cams you can't go wrong with these. Good trade off between being small enough for weight but still large enough to clip. As my rack continues to grow, so will the number of these that come with me every time.

Best wire gate availble. Small and light, this biner clips easily and you can rack a boat load of em. I think the color coding is a little lame, but I am sure some people will really like it, either way the color has no effect on the biner, it is still the bomb.

This biner is great for racking camalots since the anodizing matches

I didn't use to believe in color coding my rack, but once I tried it my climbing efficiency went through the roof, these biners are the way to go and they are pretty light with reasonable pricing. Do it!

I find these carbiners easy to clip, even though they are somewhat small. The newest version of BD Hotwires weigh exactly the same, but are larger and easier to clip. The only reason I would choose the Neutrino is if I really needed the color variety - I don't think Hotwires can match the rainbow yet?

Sturdy, good gate spring tension, and light.

Super light, super small, gate is a little stiff but oh so nice. Well reviewed biner, but may be too small (big/clumsy hands? not for you). Good/better with small ropes (<10mm). Hella light/small.

I use them for everything... Alpine draws, clipping into my gear, as extra biners in case of emergency. I like that they come in colors so I can color code for quick ID of gear on my sling.

BD does a pretty good job of getting it right. Good size, light, and the colors actually do help organize, and find your gear. Price not too bad either. Get some and spice up your rack!!

very light weight, and clip's nicely. i have steadily been replacing all of the biners on my rack with neutrinos

This is THE beaner I use across my rack. Gone are the heavy and bulky Ovals (they serve a purpose) to be replaced by a mix of these and Hotwires.

Black Diamond makes quality gear. Period. I like to rack my SLCD's on these tiny biners. If you look at the specs, they are just about the lightest biner out there. I personally don't like to use them as a quick draw because they are too small for my hands. Instead I use the Hotwire for this purpose.

The thing I like about these most is how easy they are to clip. The gate is smooth but snappy and they fit into my hand perfectly. Great for racking gear as they match the C4 and C3 BD cams. For the price these are 100% worth it.

All of my cams get one of these biners in matching colors. It makes it really easy to grab the right cam the first time

I really love these biners. they are lightweight, which is great. my favorite aspect is the color coding. i climb almost exclusively with camalots, and being able to look at your harness / sling and know what piece you are pulling strictly based on biner color is a pretty sweet advantage. whenever i buy new bd cams, i get nuetrinos to match. a little anal, but its my system and i really dig it. i actually rack my small set of master cams with my c3's with the same color biner as the similar sized c3 and it helps with the re-rack as well as pulling gear off to place it. i guess i am just much more familiar with BD's color coding system. I actually always feel more comfortable climbing with my cams vs a partners b/c of my neutrino racking system. I highly recommend them.

Works great.

I got these shortly after I ordered a set of cams, and it makes it really easy to organize the cams by color/size.

It's light, it's a wire gate and it works. What else can I say?

Fill your entire rack with these things, and you'll be amazed how much weight and bulk you save. They're a little smaller than your average biner, but still plenty big for what they do. I really like using them to make alpine draws - they just make other quickdraws look so heavy and bulky.

My favorite for racking my cams. Color coded, smooth gate, and enough room to clip runners/ropes!

Light weight, yet not so small that its hard to handle. And unlike many other light weight/small biners it still has a rope friendly diameter. 8+ KN open gate strength.
No wonder BD had a huge shortage on this biner last spring and summer.
Definitely a huge fan.
