Rolling resistance is the biggest selling point for ceramic bearings. Because ceramic bearings are rounder with a smoother surface and more uniform size, friction is reduced and that can contribute to less energy required to turn the cranks or spin the wheels. A ceramic bearing is also harder than steel bearings (up to 30%), which improves durability, and they also don’t rust so less maintenance should be required.
