As Cannondale notes, their Ryker helmet is only missing a light bar and winch. The silicon-alloy-reinforced exoskeleton cage couples with an internal roll cage to disperse and redirect any impact through the dual-density foam body. Sounds heavy, but Cannondale has shaved weight from their entire helmet line, including the Ryker, by implementing the cone-shaped impact-absorbing zones used by car manufacturers. Tank protection without tank weight. ($85, cannondale.com)
