The NILS EXTREME WHITE MATTE PU Wheels are made of polyurethane. The most important parameters of the wheels are hardness and diameter. The hardness of the wheels affects both driving comfort and surface grip. The PU-82A wheels provide good shock absorption and excellent adaptation to any surface. The diameter of the wheels has a direct impact on driving speed. Larger diameter wheels allow for higher speeds but do not guarantee the same maneuverability as smaller diameter wheels.

The ABEC 9 bearing, made of high-quality carbon steel, ensures excellent hardness and durability. It features the lowest rolling resistance, which translates to the highest speed according to the American standards of the Annular Bearing Engineering Committee, abbreviated as ABEC. An important parameter of this bearing is its eccentricity, or roundness in the inner ring track, which is only 0.0012mm.
