Innova Discs with a Bead

A bead is a slightly rounded and raised edge that runs along the entire rim of the disc (usually the rim bottom). In some cases, like in the Racer driver, a bead is found along the nose of the disc (top of the rim). The Innova Roc was the first disc produced with a bead. Why? According to Innova Co-Founder and Disc Inventor Dave Dunipace, the bead was designed to reduce wear and reduce the sharpness of the disc’s bottom. It does affect stability, in a sense, because of how it reduces wear, resulting in the disc remaining stable for longer.
