PU 70x24 82A (4pcs.) PINK + ABEC-7 (8pcs.) NILS EXTREME SET

Product description

PU PINK 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 the comfort of driving and the grip on 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 driving. Larger diameter wheels allow for higher speeds, but do not guarantee as much maneuverability as smaller diameter wheels. ABEC 7 bearing, made of high quality carbon steel, which provides excellent hardness and durability. It is characterized by the lowest rolling resistance, which translates into the highest speed in the American Annular Bearing Engineering Committee standard, abbreviated as ABEC. An important parameter of this bearing is eccentricity, i.e. roundness on the track in the inner ring, which is only 0.0025 mm.
