Aluminum 2-speed holder bulkhead is separate from the rear bulkheads to give proper flex and maximum traction. The bulkheads have an extra mounting position ââ¬â 3 screws instead of 2 ââ¬â for even greater reinforcement of the rear layshaft area and improved on-power stability. The ball-bearing is installed in a composite bushing to eliminate vibration from the engine. The holder is CNC-machined from premium Swiss 7075 T6 aluminum to ensure the lightest & strongest support framework for the 2-speed. Black color.
