When DMM introduced the Dragon in 2010, they definitely aimed high, trying to compete directly with the market-dominating Black Diamond C4. Combine that with a high price tag and a sleek, stylized look, and people were chomping at the bit to see what they were really like.

Aside from the sleeker look, though, it’s clear the Dragons are built on a blueprint very similar to the C4s. In fact, it takes more time to list the ways in which they are similar than to find and list their differences. Both have four lobes, both are built on a twin-axle head design, and not only do the sizes line up almost exactly with the C4 line (up to number 4, anyway), but the colors are the same—a gold number 2 C4 covers the same range as a gold number 4 Dragon. For those used to Black Diamond’s scheme, this makes integrating Dragon cams into your rack extremely easy.

The differences between the two are really only apparent on the spec sheet. The Dragon lobes have a slightly smaller cam angle of 13.75° (the same as the Wild Country’s cam lines), though that probably isn’t enough to make a difference in the experience of using the cam. The Dragons also use thinner lobes made of harder aluminum that are slightly lighter, but the softer Black Diamond metal bites into rock more.

The DMM in Practice

Despite these similarities, my experience with the Dragon cams was very different from other cams I have used (Metolius, Wild Country, CCH, Rock Empire, Wired Bliss, and several generations of Camalots). This is, in my opinion, primarily because of two things.

The first is the short stem on the cam. At 12cm for the number 4 Dragon, the stem is substantially shorter than both C4s and Wild Country Friends—shorter even than Metolius Mastercams, making the Dragons comparable to TCUs in this regard. I found this to be enough to occasionally make the placements difficult to reach. The number 6 Dragon, the largest in the line and sized for fist-cracks, has a stem length of 15cm.

Obviously, this is not a problem across the board: if you’re climbing laser cut cracks at Indian Creek, this won’t make a bit of difference. I did notice it, however, when using them in the flaring cracks of Lumpy Ridge. For the most part, it’s a difference that you don’t notice, but from the one instance where it made fitting a placement noticeably more difficult, I could see how it could be a deal-breaker for certain climbers.

  1. Regarding the above issue:
    Despite being pretty smitten by this addition, I did have one complaint: occasionally, I would re-clip the racking carabiner to extend the sling, and the stiff, sewn segment of the sling that holds the two ends of the loop together would catch in the eye-holes in such a way that was difficult or cumbersome to work with. Accepting that this is an unavoidable consequence of having an adjustable sling, I still love this aspect of the Dragon cams.

    I have dragon cams and solved the problem of the sewn section of the sling getting caught in the eye-holes by adding a rubber band (made out of bicycle inner tube) to the sling. This keeps the sewn section close to the carabiner and prevents carabiner rotation just like on a regular quick draw. I guess you could use a Petzl string for the same purpose, if you’re rich and famous rather than poor and infamous like me!
