A very strong and durable material, Alconite® is the latest in a long line of ceramic rings developed by Fuji. Alconite® is so durable it can be made thinner than any other ring, so strong it will hold up to all kinds of fishing demands. Alconite® has an 80% greater compression strength and is 20% lighter than aluminum oxide, making it one of the toughest rings used for fishing, as well as one the lightest. Combined with Concept guide frames, Alconite® ring guides & tops continue Fuji's tradition of producing components that enhance a rod's performance.
