PU 64x24 82A BLACK MATT (4 pcs.) + ABEC-9 8 pcs.) NILS EXTREME SE

PU BLACK MATT NILS EXTREME wheels are made of polyurethane. The most important parameters of the wheels are hardness and diameter. The hardness of the wheels determines both driving comfort and adhesion to the ground. PU-82A wheels provide good cushioning and excellent adaptation to any surface. The diameter of the wheels has a direct impact on the speed of travel. Larger diameter wheels allow you to achieve higher speeds, but they do not guarantee as much maneuverability as wheels with a smaller diameter. ABEC 9 bearing, made of high quality carbon steel, which provides excellent hardness and strength. It is characterized by the lowest rolling resistance, which translates into the highest speed in the American Standard Annular Bearing Engineering Committee or ABEC for short. An important parameter of this bearing is eccentricity, i.e. roundness on the track in the inner ring and amounts to only 0.0012mm.
