The light weight of the ceramic bearings denotes a faster forward movement which is always preferable for the rider. On the other hand, the hard and smooth surface of the ceramic bearings results in minimal friction, which means reduced levels of resistance for the rider. In addition, the surface contributes to a decrease in vibrations during cycling, implying a smoother driving experience. Therefore, also less depletion of the rider on longer journeys.
In fact, research shows that ceramic bearings lower the beats from 2 to 5 beats per minute, allowing you to save up to 10-12 watts. In addition, another property of ceramic bearings is that they do not rust resulting in long durability.
A ceramic is an inorganic, nonmetallic, solid material comprising metallic, nonmetallic or metalloid atoms, mainly held in ionic and covalent bonds. This article gives an overview of the ceramic materials from the point of view of the science of materials.
The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, vitrified and often completely amorphous (eg, crystals). Very often, cooked ceramics are vitrified or semi-vitrified such as earthenware, stoneware and porcelain. Variable crystallinity and electron consumption in ionic and covalent bonds make most ceramic materials good thermal and electrical insulation (extensively researched in ceramic engineering). With such a wide range of possible options for the composition / structure of a ceramic (eg almost all elements, almost all types of bonding and all levels of crystallinity), the amplitude of the subject is broad and the identifiable attributes hardness , toughness, electrical conductivity, etc.) are difficult to specify for the group as a whole. General properties such as high melting temperature, high hardness, low conductivity, high modulus of elasticity, chemical resistance and low ductility are the norm, with exceptions known to each of these rules (eg piezoelectric ceramics, glass transition temperature, superconductive ceramics, etc.). ). Many composite materials, such as fiberglass and carbon fiber, while containing ceramic materials, are not considered part of the ceramic family.
