National Cycle VStream Windshield - 25in./Clear No Vent Cutout N20012

National Cycle VStream Windshield - 25in./Clear No Vent Cutout N20012
National Cycle proudly introduces a revolution in windscreen performance! To offer a quiet, comfortable ride, other manufacturers will offer taller windshields or spoiler tops to lift the air stream. National Cycle designed, for the first time ever, a windshield with airflow calculated and adjusted to really quiet the riders environment. The typical airflow pattern of the wake from most windshields is called a van Karman vortex. At speeds of 50-90 mph, the air swirls off the windshield in an approximate 90-degree segment of rotation. It rolls off the windshield, hits the bottom of the riders neck on the way up, and curves off the shoulder at approximately 45 degrees. National Cycle gave the VStream its name for the shape it takes at the upper edge. The V shape is so outstandingly quiet because it pushes this vortex out and away more than 4 inches from the side of the riders head. The riders helmet then resides in still air, and the passengers environment is greatly improved as well. State-of-the-art Quantum coated Lexan polycarbonate gives VStream windshields outstanding optical clarity and strength characteristics unmatched by any windshield maker worldwide. This exclusive combination of Quantum coating on 4.5-6.0mm thick Lexan material increases scratch resistance 30X over other manufacturers acrylic shields.
