When Gitzo launched the Mountaineer tripods in 1994, they were the World"s first carbon fiber tripods. Ever since then they have set the standard for performance and quality. The main feature of the range is the new 6X carbon fiber tube, made of a unique structure of 6 crossed layers that maximises rigidity, vibration absorption and lightweight performance. 6X tube has a high density structure made of top quality ultra-thin carbon fibers (7?m or 0.007 mm). Built-in Anti Leg Rotation is now a feature of the whole carbon fiber range. Mountaineer tripods have been further improved with features and details that increase performance, versatility and quality. Gitzo GT1540 replaces Gitzo GT1158.
