The PU PINK WHEELS NILS EXTREME 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 riding and the grip on the surface. The PU-82A wheels provide good shock absorption and excellent adaptability to any surface. The diameter of the wheels directly affects the riding speed. Larger diameter wheels allow for higher speeds, but do not guarantee the same agility as smaller diameter wheels. The ABEC 7 bearings, made from high-quality carbon steel, ensure excellent hardness and durability. It has the lowest rolling resistance, which translates to higher speed according to the American standards set by the Bearing Engineering Committee. An important parameter of this bearing is the eccentricity, or roundness on the inner ring track, which is just 0.0025mm.
