Lightweight adult helmet for road bikes, gravel bikes or leisure rides. Shock-absorbing rigid foam foamed into an impact-resistant outer shell - the In-Mold process creates a durable bond for a robust helmet. Precisely adjust the helmet to the circumference of your head using the Zoom Ace adjustment system and an easy-to-grip adjustment wheel at the back. The height-adjustable adjustment system at the back of the head creates space for a ponytail, making it ideal for men and women with long hair. Floating padding is attached at three select points, ensuring better mobility of the padding, ventilation, and comfort. Forced Air Cooling Technology connects front and rear vents with deep channels for a cool head, plus the PowerDome (air scoop on top) for the Venturi effect. Flowstraps are lightweight webbing that completely hugs the face, preventing flapping and improving aerodynamics.
