The PU MILKY WHITE NILS EXTREME wheels are made of polyurethane. The most important parameters of the wheels are their hardness and diameter.
The hardness of the wheel determines comfort while skating and grip. The PU-82A wheels offer good shock absorption and excellent adaptation to any surface. The wheel diameter directly affects skating speed. Wheels with a larger diameter allow higher speeds but do not guarantee the same maneuverability as wheels with a smaller diameter.
The ABEC 7 bearing, made of high-quality steel, provides excellent hardness and durability. It is characterized by the lowest rolling resistance, which translates into higher speeds according to the American Bearing Manufacturers Committee (ABEC) standards. An important parameter of this bearing is the eccentricity, or roundness, of the inner rail, which is just 0.0025 mm.
