DMM Dragon Cams set include 00/0/1. With the single stem design, the two axles allow a greater range for each camming unit. They use Ray Jardine\'s original 13.75° constant camming angle, for the perfect balance between holding power and range. Hot forging process for the cam lobes (in sizes 1 to 6) produces a highly sophisticated shape in A6082 alloy for added bite, and significant weight saving. Strong springs make the cam sit more securely, and also more resistant to being pulled out of slippy placements and the potential for \'walking\' is reduced. Their patented lightweight forged thumb grip makes the grip and trigger combination sit perfectly in the hand - even when you\'re wearing full winter gloves it handles like a dream. The double extendable 8mm Dyneema sling means you only need one biner for each cam placement - another significant weight saving.Dragon 00 (Blue): Weight = 75g, Strength/Passive Strength = 9kN, Range = 13.6-22.5mmDragon 0 (Silver): Weight = 85g, Strength/Passive Strength = 12kN, Range = 16-26.7mm Dragon 1 (Purple): Weight = 97g, Strength/Passive Strength = 14kN, Range = 20-33mmLightweight single stem cam with dual axles Special thumb grip and trigger bar for easy handling Hot forged cam lobes to reduce weight A6082 cam lobes for added bite Original 13.75° camming angle Fitted with extendable 8mm Dyneema slings Colour coded for speedy identification 14kN in passive position (sizes 1-6)
