    Camalot X4

    If you're looking to add some small cam sizes to your rack, the new Black Diamond Camalot X4 is the way to go. The 4-lobed device utilizes embedded cam springs to create a narrow head width while the stacked and double axle technology provides the largest expansion range of any small cam available, ultimately providing more placement options than ever before. Plus, aluminum protection beads on the stem increase durability without compromising flexibility.

    • Stacked axle technology (sizes .1, .2, .3) and double axle technology (sizes .4, .5, .75) allows for a huge expansion range
    • Cam springs embedded in the lobes create a narrower head width than the original Camalot, allowing for wider range of placement options
    • Aluminum protection beads around the cable increase durability without limiting flexibility
    • Hot-forged trigger and the symmetric swage improve handling characteristics
    • Slung with color-coded Dyneema slings for easy size identification
    • Item #BLD3430

    So functional!

    • Familiarity: I've used it once or twice and have initial impressions

    These are the small cams I trust a lot. I saw a friend in Moab fall on one a few times trying a move and he didn't have any concerns at all. Really good for awkwardly placed cracks.

    Small, and Flexy

    • Familiarity: I've put it through the wringer

    I'm a big fan of these. Especially, the smaller ones. I have noticed , that with the flexible stem , they can wiggle their way into some tough spots to clean , though.

    My Favorite Small Cam

    • Familiarity: I've put it through the wringer

    These live up to the reputation Black Diamond built with the C4's. They feel great in the hand, the trigger action is nice and smooth, and the quality is very apparent when you pick one of these up. These overlap a few sizes with the C4s; up to the purple, I'd go with the X4s every time. The green X4 can feel a little floppy as other have mentioned, but it is still a great piece. Racking one green c4 and one green x4 is not a bad idea as the X4 has the versatility with the much narrower head and flexible stem for for finicky placement.


    • Familiarity: I've used it several times

    I snagged a few of these because I always find myself reaching for a smaller cam to put in places I don't really want to put my hands and leaving good cracks for my fingers instead. These cams are slim and lightweight so they don't add too much to your rack. Plus, the heads aren't as wide, which gives you a more versatile range of places you can stick them, like littler pockets and such. Big fan, there's a reason they're a classic.

    Confidence Inspiring

    • Familiarity: I've used it once or twice and have initial impressions

    I have been putting together my first trad rack over the past month or two, and I ended up grabbing a 0.3 and 0.4 to round out my rack sizes. Though I havent fallen on my X4s yet, I have placed the 0.4 a couple times and each times it gives me more psychological protection when I need it on those tiny cracks. Definitely a more niche use for me, but they are great for any climber needing good pro in vertical or diagonal cracks or those who send it really hard.

    X4's are AMAZING

    • Familiarity: I've put it through the wringer

    I have the 0.3-0.5 X4's and they are amazing. The grey (.4) is my favorite and fits everywhere! I have whipped on it twice now and it didn't budge. Awesome small cams!! Can't been 'em. Will be adding more to the rack when I can afford it.

    Small and strong.

    • Familiarity: I've used it several times

    These cams are one of my go-to trad pieces, I never leave the ground without at least one or two of them. They are small, finger sized pro for protecting those scary moves where you're hanging on only your fingers, and let's be honest, those happen even on easier climbs. I place these guys when I just need some extra courage to go forward. Plus, with the metal necks, these guys can take a beating and still stay in great shape. A must have for your rack.

    Love the Skinny Head

      I have been using my X4 set everywhere! Because they just seem to fit everywhere! I have pulled my C4 off my belt to only find the slot is too small and then find that the X4 fits. I don't feel any less secure on the X4s because of the smaller head. Some say the .75 head is a little floppy on the stem but I don't think its that bad, its just what you expect from a single stem cam like this.

      Perfect for the small stuff

      • Familiarity: I've used it several times

      I like the X4s a lot in the smaller sizes, where the flex does not inhibit placing them with one hand. If I could, I would rack these exclusively, but I have a Frankenrack, so I often find myself saving these for the tricky horizontal placements where they really excel, and using a different cam in simpler placements.


      • Familiarity: I've put it through the wringer

      This is the perfect small cam package to add to your trad rack they will definitely have there place. The extremely flexible stem is perfect for horizontal placements and gives me more confidence then a C4 in the same spot. These cams have nice trigger action feel great in your hands and have an amazing range. I find my self placing the X4s more often then the same size C4 when climbing in Big and Little Cotton Wood Canyon. I highly recommend these to anyone looking for smaller size cams. They are worth the extra money. If you have any questions building your rack hit me up any time!


      Hands down my favorite

        I love these things. I have a complete set and wish I had more. They are a full lobe maybe more compact than the c4. They place better in horizontal or weird cracks.I reach for these first when looking at my rack. I trust them with my lie and they have never let me down. I place the .2 a ton.

        Love the X4s

        • Familiarity: I've put it through the wringer

        These are my favorite small cams. Had the blue and the yellow and recently added the red and the grey. They are easy to place, have a great range, and have held solid on a couple of decent falls. The flexible stem is nice for horizontal placements, and I like the action much better than comparable size TCUs or C3s.

        My favorite small stuff.

          All the small things.... True care, truth brings.... I'll take, one .1.... whip on it/best trip.... Always, I know.... You'll be, on my rack... Clipping, placing, and taking.

          Say it ain't so, I will not fall.... Peel my hands off, save my ass cam.... on, on, on, on..... on, on, on, on, on, on, on belay.

          Just a great cam

          • Familiarity: I've used it several times

          Stem that bends for better horizontal placement. Check. Great range from either dual or stacked axles. Check. Durable head and stem with armor. Check. Fantastic cams.

          necessary purchase

          • Familiarity: I've put it through the wringer

          You'd think who cares what's the difference? The difference is these fit when C4's don't. Don't believe the reviews try them out and you'll get more.

          Have brutally whipped on .1 and it's still going strong.

          Great, but buy them on sale

          • Familiarity: I've used it several times

          At the recommendation of a local gear shop, I opted for the .3 and .4 (blue and grey) in X4s rather then the same size/color in C4s. And I would make the same recommendation to anyone else, it was good advice. At least for the .3/.4, they have a slightly better range than the C4 counterpart-- several times I've had a .4 C4 not fit as well in a crack as the .4 X4 did. And the flexible stem is great if you have to place in a horizontal crack.

          From those of you who have several of these...

          From those of you who have several of these or all of them, what size would you recommend for someone who is just getting their first trad rack together?

          Best Answer

          You can probably skip the .1 and the .75. The .1 is very small, and it's unlikely that you'll find a place to use it (or be willing to fall on it if you do) and the .75 overlaps a lot with the #1 Camalot. Other than that, I'd get all of them. If you have to pick just one, make it the .5 or the .4, as they have the most range.

          Bad information above. The .75 X4 overlaps with the .75 Camalot. My experience with the double-axle X4's is that the range is limited by the poor connection of the trigger "wire" to the cam lobe. As a result, they don't retract for the full range of motion when the trigger is pulled, but can if pushed into a crack. This contributes to the likelihood that they will become fixed.

          Get the single-axle X4's to cover the smaller end of your rack range.

          Depends on where you climb the most.

          Having a diverse rack is always a good thing. For complete set of X4s you could probably buy double the amount of offset brassies (nuts).

          I'd buy fingers to .5, then switch to regular C4s for the rest of your sizes. Buy small nuts for anything else

          One more question. Do any of you who use small cams as pro ever put screamers into your system in order to reduce the load on your pro in case of a fall?

          Best Answer

          Yes I have certainly used screamers on smaller gear to minimize some of the impact forces but I have largely done that while aid climbing rather than free climbing. Sometimes when I'm a bit nervous with the smaller gear I'll build a little life nest of cams and nuts or whatever works and quickly equalize them before punching it into a crux.

          I am no pro at all but I have never used a screamer with a small cam, I just put my trust in the cam and I just use more of them because they are light and with more it is more trustworthy in a fall! Hope this helps you at all!

          I am looking to add some smaller pieces...

          I am looking to add some smaller pieces to my rack, but I wanted to know if the smaller x4's, .3 and .2 in particular, are rated for taking a fall. I see that the .3 is rated for 8kn and the .2 is rated for 6kn, are these safe for taking a fall, or are these small size cams designed for aiding/anchor making?

          Best Answer

          You can use the smaller sizes for free climbing. The only piece that I have seen BD listing for direct aid only is the 000 C3 which has a rating of 4kN. I would be wary of taking huge falls but I am not seeing anything stating the .2 is a direct aid piece.

          I'm a huge fan of both the C4s and C3s but...

          I'm a huge fan of both the C4s and C3s but have yet to handle the X4s. I was speaking to someone the other day about them and he said the larger sizes have a tendency to "taco" due to the heavy head and flexible stem (when you pull the trigger, the stem just bends instead of the cam activating). Any comments from those that have handled them? Thanks!

          Best Answer

          I used #0.75 green and #0.4 gray, and #0.3 blue. Blue and gray are perfect (at least while new). The green was good-enough. I mean it was really good, stable and easy to operate. But not perfect - a bit on a soft side. With aging it probably could ("probably could" is far-far away from "definitely will") become dirty and begin to "taco". Thus I decided to keep both C4 and X4 in a green 0.75 size - I will use C4 as an universal green size piece and reach for X4 when I need a narrow head in this size (not too often).

          For blue 0.3 and gray 0.4 sizes X4s are hard to beat.

          In short:

          - If you are building a rack it is probably better to get X4s up to gray 0.4 and C4x purple 0.5 and up.

          - If you are extending your existing rack go for X4s in all sizes.


          I got my hands on the full range of x4's almost 2 months ago. I've climbed maybe 4-5 times since and I didn't get the feeling that they are harder to place because of the taco effect (hmmmmm tacos). That beeing said, You do get a feeling that the trigger action is not as good as the C4's when you play with them. On the rock though I didn't think about it at all.

          On top of that, the plus side of it is super! the flex is so good and it makes me believe that they tend to walk less. Placing them in horizontal cracks is just so delightful!

          So, I'd go for a full rack of these! they are really fun to place and are a great addition to the rack.

          What's going on with the production of the .2 and .1 x4 cams? No one has them, and no companies appear to be notified of future shipments.
