The Gitzo G1227 Mountaineer II Carbon Fiber Tripod is 30% lighter than equivalent alloy version without compromise on strength, tensional stability or durability. Unparalleled Strength Gitzo carbon tubes use an exclusive process based on pull winding of long Carbon Fibers which are precisely wrapped and combined under high pressure and temperature with epoxy resin to a 1.5mm wall thickness. This manufacturing process ensures stiff, light tubes resistant to bending, has good tensile and compression strength, a high degree of stability in extreme temperatures, absorbs vibration and withstands fatigue better than other Carbon Fiber tube processes. Grooved Carbon CenterColumn Unique grooved, carbon Rapid Centercolumns are now fitted to prevent rotation and increase stability and include stainless steel weight hook. HIS Technology Mountaineer tripods are now constructed using a "screw thread and glue" dual jointing technology pioneered by Gitzo called "HIS". This provides greater strength and security on location. Smooth Control Telescopic leg extensions can be set without slippage with rubber cushioned leg locks.
