DMM Dragon Cam 1 (Original Version)

The DMM Dragon Cam 1 is the size 1 piece from the original range of Dragon climbing cams.

DMM spent over 2 years designing a single stem camming device that would compliment their existing range of 4CU rock climbing cams. They eventually decided to use a double axle design and work out the weaknesses - weight, cam angle, stems twisting and lack of a doubled sling. Hence the original Dragon cam was born. 

DMM Dragons have been designed without compromise to produce a blend of strength, lightness and functionality. The cams use a single stem with hot forged cams mounted on a dual axle. They have kept Ray Jardines original 13.75 degree constant camming angle that maximises holding power without compromising range. And also kept the extendable, double dyneema sling that saves on quickdraws and reduces the weight of your rack even further. These are the fundamentals around which Dragons are designed.

The cams use relatively strong springs - this means the units feel slightly harder to retract, but the advantages are worth it: they will sit more securely in placements, they will have improved resistance to being pulled out of low friction placements and they will walk less.

The patented thumb termination uses an aluminum forging that is massively strong, resistant to abuse and crucially lets us use an extendable sling. It was not possible to use a wire loop with an extendable sling because it was found that the dyneema sling was cutting through the wire thumb loop (This does not happen on the 4CUs because of the cross bar supports the wire loop and stops it collapsing and creating stress points). The forging is actually lighter than the wire loop it replaced.

The stem uses 5.5mm stainless steel wire cover in a hydrolised nylon sleeve. The nylon sleeve rotates freely to reduce abrasion damage and gives the units really good flexibility throughout 360 degrees. In addition they have used very short terminations that increase flexibility. Thus when the cams are placed in shallow vertical or horizontal cracks the units are less likely to be levered out of the placement.
