NILS Extreme Roller wheel kit with bearings PU + ABEC-7 (x4)

The PU MILKY WHITE wheels NILS EXTREME are made from polyurethane. The most important aspects of the wheels are hardness and diameter. The hardness of the wheels affects both the riding comfort and grip on the ground. The PU-82A wheels provide good cushioning and excellent adaptation to all surfaces. The diameter of the wheels has a direct impact on riding speed. Larger diameter wheels allow for higher speeds, but do not guarantee the same level of manoeuvrability as smaller diameter wheels. The ABEC 7 bearing, made from high-quality carbon steel, ensures excellent hardness and durability. It is characterised by the lowest rolling resistance, which translates into the highest speed according to the American standard, Annular Bearing Engineering Committee, or ABEC for short. An important parameter of this bearing is the eccentricity, which refers to the circularity on the inner housing rail, measuring only 0.0025 mm.
