The PU White Nils Extreme wheels are made from polyurethane. The key 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 riding speed. Larger diameter wheels allow for higher speeds, but do not guarantee the same maneuverability as smaller diameter wheels.
The ABEC 7 bearings, made from high-quality carbon steel, ensure excellent hardness and durability. They feature the lowest rolling resistance, translating to the highest speed according to the American standard Annular Bearing Engineering Committee, abbreviated as ABEC. An important parameter of this bearing is its eccentricity, which measures the roundness on the inner ring track and is only 0.0025mm.
