DMM Dragon Cam Review
|
|
I know the DMM Dragon isn't exactly new on the market. But I've read enough flaming comments on the Dragon cam and its comparison to the Camalot that I decided I would do my own review. Another problem most people had with the Dragon cams' lack of a thumb loop was the inability to clip high while aid climbing. This was a quick fix with an overhand knot near the thumbpiece after extending the sling, and I actually found myself being able to clip in about an inch to an inch and a half higher on the Dragon due to the shorter stem and my knot being higher than the bottom of the thumb loop would be. Yet another problem people had with the Dragons were that they thought the way DMM shaved weight off of the cam was to make the lobes thinner, which would increase the force on the rock in a placement. This is both true and untrue. It is true in the sense that, yes, the lobes are thinner, but untrue in the sense that they are not thinner on the outer portion of the lobes that contact the rock. The thinness comes for the middle of the lobes (where most companies would punch holes in the metal to cut weight. The lobes are the same thickness on the outside but thinner on the interior, meaning the same force is exerted on the rock with respect to the thickness of the cam lobes(not taking into account the cam angle just yet, I'll talk about that in a little bit) I read on a couple websites that some people were concerned that with an extended sling a lot of the weight would focus towards one side of the cam because of the twin holes in the thumbpiece. I initially had this concern, but when I got my Dragons and extended the sling for the first time I saw how this problem was solved. Due to the way the sling is inserted through the thumbpiece to avoid girth hitching, the sling goes in one hole and exits another, equalizing the force. See the picture to know what I'm specifically talking about, it is a little difficult to explain. Now for the practical application. One point that DMM says really shines in their cams is the extendable sling. Now I found this to be either good or neutral. The extendable sling is supposed to be able to save the climber the weight of carry an extra draw for extending a piece. I found that on climbs that don't wander that much, this is a savior of weight, I only had to carry draws for my cams that weren't Dragons. However as most know, there are many routes that do wander. This is where my neutral opinion is. The extendable sling really doesn't do that much for these types of climbs, and you almost always have to carry an extra draw anyway to extend the piece. However, it doesn't hinder the climber in any way, because they'd have to be carrying those draws anyway, thus, neutral. See the picture for the length of the sling when extended The 13.75 degree cam angle is another bragging point for DMM, as they say that it creates a greater holding power. Holding power is a very subjective term, but it does create a greater outward force. This can be either good or bad for a climber. Like I previously said, I tried these cams out in both sandstone and granite. In my opinion, the dragon cams felt more bomber than the Camalots in granite, but were a little sketchy in sandstone. As most know, in sandstone the rock gives a lot more than granite, and the greater outward force of the cams creates a shifting sound of the rock when the cams are weight/fell on. A comparable situation would be Metolius's line of cams, which have a similar camming angle, and I've found do almost the exact same thing in sandstone. That said, I didn't have any of the cams fail when fallen on (however, the falls weren't that large). The smaller camming angle does give for a greater potential of failing rock in sandstone though. However they will still perform very well in that rock type, and perform as good if not better in granite than the C4s. |

It looks like the lobes of the dragons are rounded which means less contact area with the rock. The total width of the lobe may be the same but it looks like the actual contact area might only be half. |

This whole thread is negated if you have a dragon cam in sizes 4-6, as they noted the turned axle bosses are cracking down the middle. |

Dragon Cam Recall I suppose if you have the new version of Dragon Cam with hot forged axle bosses, then this thread applies, and I thank you for sharing your thoughts on the Dragon Cam. I have the new 4-6, the one with the "X" shaped axle boss |

The axle boss doesn't apply to what is said in this review since this review basically just describes a few of the features of the cam, not its ultimate strength or reliability. |

It's funny; my findings with the Dragons were almost exactly opposite of yours. |

If I were on a big wall or in the back country or alpine environment it would be nice to have an option this light. Looks like it is 1.5oz of weight savings for a full set of 6 (33.2oz total for the 6 dragons). Seems to depend on the size though - 1 and 6 are basically the same weight as camalots, while 2-4 are significantly lighter. |

Regardless of the specs posted online, grabbing a set of each and comparing on a flat surface will make the difference obvious. I was interested in a set, but passed on them after seeing the crappy forging job for the lobes. C4's are CNC'd. Dragons have the usual pitting, rounding and flash marks on the lobe contact surface that go with stamping/hot forging - similar to the 1st and 2nd generation Camalots. Nice cam, but not as good as a C4. Yea, I'm no engineer or metal worker but I think the forging is what threw me off. I am used to looking at machined metal from BD and Metolius. |

Are you guys seriously against forging? It's not like CNC machining is a more advanced manufacturing process. |

I am an engineer and a metal-worker so let's see if I can put this machining vs. forging discussion to bed with a simple question: |

I also looked at these in the shop yesterday and the lobes of the dragon are visibly narrower than the C4 where they contact the rock. That means that the reduced contact area will exert more concentrated force on the rock where it is placed. |

Unless it blows out the rock, I fail to see how this issue of "narrow lobes" has any bearing on the rock at all. |

I bought a dragon in the .75 camalot size (green) of these shortly before heading to Joshua tree on a trip. I hated the way cam placed so much that I gave it to a friend who exclusively topropes. |

I hated the way cam placed so much that I gave it to a friend who exclusively topropes. I simply couldn't get the cam from my harness to a solid placement in a reasonable amount of time. I'm sure they're really wonderful if you want something to shave grams or if you only put in gear from ledges, but in my opinion they are poor lead protection when pushing your trad redpoint grade. My opinion has nothing to do with strength, it is simply a matter of one handed usability compared to bd c4s. I will not purchase another of these overpriced knockoffs and I would suggest that you don't either. So because you lack proficiency in placing these cams you're saying don't buy DMM Dragons? That's ridiculous! |

I was actually saying that they are harder to place than other cheaper, nearly identical cams. I don't feel the need to make gear placement the crux of my gear redpoints. |

Your name is Manlove? That's a tough handle to boast. |
