Bell Ghisallo Road Bicycle Helmet Special Colors. Race proven at the highest levels of professional cycling, the Bell Ghisallo Bicycle Helmet features a sleek, streamlined design loaded with high tech features. Its name pays special homage to the Madonna del Ghisallo, the patron saint of cycling whose famed chapel in northern Italy majestically overlooks Lake Como, and it's only natural that the protector of cyclists has been tasked with ensuring your head stays cool, comfortable and safe. The fusion in mold microshell provides incredible strength while the internal reinforcement provides room for massive vents and less material with no sacrifice to protection. And achieving a perfect fit has never been simpler via Bell's GPS Geared Positioning System which provides one hand adjustment.
