Designed to eliminate twig-damages. Why Ceramic, why C-Bear? Lightweight: Si3N4 ceramic balls are significantly lighter than steel balls, reducing rotational mass and enhancing overall bike performance. Low Friction: The smooth surface of Si3N4 ceramic balls reduces friction, leading to improved efficiency in the cycling mechanism. High Hardness: Si3N4 ceramic balls exhibit exceptional hardness, resulting in greater durability and resistance to wear, thereby extending the lifespan of components. Corrosion Resistance (water, salt water and many acids) : Si3N4 ceramic balls are highly resistant to corrosion, making them ideal for cycling applications where exposure to moisture and harsh conditions is common. Reduced Maintenance: Due to their durability and resistance to wear, Si3N4 ceramic balls require less frequent maintenance compared to traditional steel balls, contributing to long-term cost savings and hassle-free cycling experience.
