Bike Helmets

Building on the success of the Full-9, along with feedback from trusted athletes, and featuring new technologies we developed in-house, the Full-10 Spherical was engineered to be the new standard in D more→H fit, protection, and style. Created in the Bell+Giro testing Dome in Scotts Valley, CA, our proprietary Spherical Technology™ powered by Mips® features a Balland-Socket design that helps redirect impact forces away from the brain, allowing the outer liner to rotate around the inner liner during a crash. In addition, the Spherical Technology channels inside the lightweight unidirectional carbon shell allow us to achieve superior ventilation like never before—what we are calling
