This is Doubletakes new and improved 6" (150mm) arm, it is a little longer than anything else on the market, for great visibility on loaded bikes. Technical Specifications Length center to center: 6" (150mm) Length overall: 7" (178mm) Arm weight: 150 Grams Material: A380 Die Cast Aluminum Lifetime Warranty Better hold, less effort. The whole system has been engineered together to keep the mirror from moving, except when it has to in an impact. Longer Length. The Doubletake Arm 6.0 is 15% longer than anything else on the market, offering great visibility especially around luggage. Radial Ridges. The clamping surface at the base has radial ridges to hold the ball more securely. These ridges prevent the arm from unintentionally rotating relative to the base, but without mechanical interference that could be damaged under impact. Asymmetrical Clamping. Because the ball diameters are different, the clamp is located off-center toward the mirror. The larger base diameter creates more stiffness at the bottom, and the offset clamp grips the mirror tighter to equalize rigidity. Easy Adjustment. Our low profile thumb nut is 25% longer to make adjustment easy even wearing gloves. Compatible. Mirror end 1" socket works with any 1" ball accessory (GPS, Camera, etc) Requires Doubletake ball kit for base.
