Aerodynamic Shell Design * Aerodynamic properties are maximized through extensive wind tunnel and professional riders feedback.* Dual Layer EPS liner enhances impact absorption and ventilation.* Five shell and six EPS liner sizes present increased fit options that help to comfortably fit most head sizes.* A third generation Tail Fin integrated into the bottom rear beading in combination with the Shell-Integrated Spoiler allows smooth airflow that reduces drag and lift. Variable Ventilation System * Upper Air Intake Vent is positioned to maximize air volume into the helmet interior.* Top outlet vent is separate from the Shell Integrated Spoiler allowing it to be positioned for optimum flow-through ventilation.* Four rear outlet vents allow for adjustment of airflow based on riding position.* Enlarged lower air intake/defroster vent reduces shield fogging and increases ventilation.* The rear/neck outlets allow for effective air exhaust.* Breath guard and chin curtain included. Lightweight Advanced Integrated Matrix Plus AIM * High performance fiber materials are combined with extremely elastic organic fibers to create a shell structure that is ultra lightweight rigid and resilient. Interior System* The entire interior lining cheek pads crown liner and chin strap covers is easily removed to allow cleaning.* Each component of the inner liner is ergonomically designed to offer the ultimate in safety fit and comfort.* Eyeglass compatible interior. Standard Chin-Strap Clip * Neatly secures chin strap. CW-1 Shield and Q.R.S.A. System * Q.R.S.A. Quick-Release Self-Adjusting base plate allows for tool-less shield removal and installation. The spring loaded base plate U.S. patent pending 11/799935 pulls the shield back to contact the window beading evenly and ensures a roper seal.* The CW-1 three-dimensionally curved shield is both wider and taller than the CX-1V it replaces.* Optional CWF-1 two-dimensional racing shields with tear-...
